Description

  The present invention relates to a manure processing method and a manure processing apparatus for processing manure at the time of a disaster or the like.

  In the event of a long-term power outage or water outage due to a disaster such as an earthquake, the toilet cannot be used, and a large amount of manure accumulates in each household. Malodors continue to emanate from the large amount of manure, and if left untreated, the odor will significantly deteriorate the living environment.

  In such a disaster, for example, manure is put in a plastic bag and stored in a sealed state for the time being, but the plastic bag is easily damaged, so it is damaged during storage. There is a problem that feces and urine leaks, and odors are emitted around. In addition, there is a problem that manure rots with time in the plastic bag, and the odor gas leaks out of the bag due to the pressure of the accumulated odor gas.

  Therefore, the assembly structure made of corrugated paper is made into a disposable simple toilet (simple toilet) (refer to Patent Document 1), or a frame body such as a wooden bag made of wood or paper and a bag body such as a polyethylene bag inside is simplified. It has been proposed to use a toilet body as a toilet and to dispose of a bag that receives manure (see Patent Documents 2 and 3).

In addition, as a method of actively treating manure, a method in which manure is introduced into sawdust, the sawdust and manure are stirred together, and manure is treated with microorganisms in manure (see Patent Document 4), or fine particles of quick lime. And a method for treating manure (see Patent Document 5) using the manure treating agent obtained by coating at least one type of coating agent selected from the group consisting of higher fatty acids, salts thereof and esters thereof. Proposed.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Manure processing equipment)
First, the excrement processing apparatus used for implementation of the excrement processing method concerning the present invention is explained.

  FIG. 1 is a schematic diagram showing a procedure for folding a toilet pack in the excrement disposal apparatus of this embodiment. FIG. 2 is a schematic view showing a state in which the toilet pack according to the present embodiment is arranged in the toilet bowl. FIG. 3 is a schematic view showing a state in which the toilet pack in the present embodiment is held by the toilet seat.

  With reference to FIG. 1 and FIG. 2, the excrement disposal apparatus 1 of this embodiment is a container-shaped toilet pack 10, and the excrement processing agent 20 added to the excrement received in this toilet pack 10 (refer FIG. 4). And a treatment container (treatment tank) 30 (see FIGS. 6 to 9) that performs the exothermic treatment of manure after the mixture of the feces and urine treatment agent 20 is put together with the toilet pack 10.

  The toilet pack 10 is a simple disposable container that receives manure, and at least the inner surface that receives the manure has water repellency. That is, the toilet pack 10 is formed by folding a water-repellent material having a water-repellent finish on one surface into a container shape so that the inner surface becomes a water-repellent surface, and is stored in a folded state. The opening edge F is expanded so that a space is formed, and the container is formed into a container shape (see FIGS. 1E and 2).

  Examples of the water repellent material include a material in which a resin layer such as silicon resin is coated or laminated on one surface of a combustible material such as paper or vinyl. In particular, since the toilet pack 10 of the present embodiment is folded and formed into a container shape, it is preferably a sheet-like or film-like water-repellent material that can be easily folded, for example, release paper (release paper) is preferably used. It is done.

  Next, with reference to FIG. 1, the folding procedure of the sheet-like or film-like toilet pack 10 will be described. This folding structure is an example of folding and forming the toilet pack 10 as a container, and the structure and folding procedure are not limited.

  The material of the toilet pack 10 is, for example, a square release paper, and has a water repellent finish on the upper surface (surface). This toilet pack 10 assumes SL, L1, L2, L3, and L4 lines in the unfolded state as shown in FIG.

  First, as shown in FIG. 1B, a right isosceles triangle is created by folding inward (upper surface side) with a center line SL on a square diagonal line as a reference. Next, as shown in FIG. 1 (c), on both sides of the right-angled isosceles triangle, the both sides of the right-angled isosceles triangle are folded inward and overlapped with respect to the inclined lines L1 and L2 that rise obliquely symmetrically. Create a pentagon. Next, as shown in FIG. 1 (d), with respect to the horizontal lines L3 and L4, a portion of a right isosceles triangle located at the upper part of the pentagon is opposite to the upper surface side (front surface side) and the lower surface side (back surface side). Fold each in the direction and overlap to create an inverted trapezoid. The toilet pack 10 is folded into a container shape even in this state, but as shown in FIG. 1E, the opening edge F can be reinforced by folding the opening edge F outward, and each folding piece is folded. Can be maintained. And if the folding part (henceforth "the holding | maintenance part 11 and 12") of a right-angled isosceles triangle is picked with a finger and the opening edge part F is expanded, the toilet pack 10 will be shape | molded as a simple container ( (See FIG. 2).

  2 and 3, the toilet pack 10 of the present embodiment is thus provided with the triangular holding portions 11 and 12 on both sides thereof, and the holding portions 11 and 12 are grasped with fingers and opened. The edge F can be expanded to the left and right, and can be held on the toilet seat 61 of an existing toilet seat opening / closing toilet (Western style toilet) 60 by using the holding portions 11 and 12. The toilet pack 10 may be used alone without being installed in the existing toilet bowl 60. The procedure for holding the toilet pack 10 on the toilet seat 61 of the existing toilet bowl 60 will be described later.

  FIG. 4 is a schematic view showing a state in which a manure treating agent is added to manure in the toilet pack.

  Referring to FIG. 4, feces and urine treatment agent 20 mixed with feces and urine is hermetically sealed in bag 21 having moisture resistance, and is added to feces and urine in toilet pack 10 by opening bag 21. . Although the manure treatment agent 20 may be measured and used in use, in this embodiment, in consideration of convenience, the amount of use commensurate with one or several stools is contained in the bag body 21. Sealed. The excrement treating agent 20 is a powder containing quicklime surface-treated with a hydrophobic coating agent and an exothermic agent, and may further contain a water absorbing material and / or an additive as necessary. Hereinafter, the components of the excrement treating agent 20 will be described in detail.

(Quicklime surface treated)
Although the form of the surface-treated quicklime (CaO) used in the present invention is not particularly limited, it is preferably in the form of a powder from the viewpoint of effectively dispersing the stool. The average particle diameter is preferably in the range of 0.1 μm to 5 mm, more preferably in the range of 0.5 μm to 2 mm, and particularly preferably in the range of 1 μm to 1 mm. When the surface-treated quick lime has an average particle size of less than 0.1 μm, production may become difficult and production cost may increase. On the other hand, if it is larger than 5 mm, the contact area between the obtained excrement treating agent and excrement may be reduced, and the reaction efficiency may be reduced. In addition, a lump may be generated during the excrement treatment, and unreacted matter may remain. is there. Moreover, you may use the quick lime by which the said surface treatment is carried out in combination of 2 or more types of quick lime from which an average particle diameter differs as needed. In the present invention, the average particle size is a value measured by a particle size distribution measuring device.

(Hydrophobic coating)
The hydrophobic coating agent used in the present invention can impart hydrophobicity to quicklime when the surface of quicklime is processed using the coating agent, and the coated quicklime is powdered. It is preferable that the compound be easy to make.

  Specific examples of the coating agent include, for example, at least one compound selected from the group consisting of paraffin, stearylamine, higher fatty acids, salts of higher fatty acids, or esters of higher fatty acids. Among these, It is preferably at least one compound selected from the group consisting of higher fatty acids, higher fatty acid salts, and higher fatty acid esters. Such higher fatty acids are preferably monovalent or polyvalent saturated fatty acids or unsaturated fatty acids having 8 to 26 carbon atoms, more preferably monovalent or polyvalent saturated fatty acids or unsaturated fatty acids having 8 to 24 carbon atoms, A monovalent saturated fatty acid of several 10 to 20 is particularly preferable. Specific examples of the higher fatty acid include caprylic acid, pelargonic acid, capric acid, lauric acid, myristic acid, palmitic acid, stearic acid, arachidic acid, lignoceric acid, oleic acid, linoleic acid, linolenic acid, arachidonic acid and the like. It is done. Specific examples of the higher fatty acid salt include ammonium salts; alkali metal salts such as sodium salts and potassium salts; or Group 2 metal salts such as calcium salts and magnesium salts. Specific examples of the higher fatty acid ester include methyl ester, ethyl ester, n-propyl ester, isopropyl ester, n-butyl ester, sec-butyl ester, tert-butyl ester, isobutyl ester, n-hexyl ester and the like. Or a cycloalkyl ester such as a cyclohexyl ester.

  The amount of the coating agent used is preferably in the range of 0.01 to 10% by mass, more preferably in the range of 0.1 to 3% by mass, and 0.4 to A range of 1.5% by mass is particularly preferable. When the amount of the coating agent used is less than 0.01% by mass, a sufficient reaction delaying effect cannot be obtained at the time of manure treatment, the reaction proceeds rapidly, and uniform mixing cannot be performed. In addition to the formation, the hydrophobicity of the reaction product is not maintained, and there is a possibility that it returns to the original form of manure due to water mixing. On the other hand, when it exceeds 10% by mass, the active surface area of quicklime is reduced, so that the reaction may not proceed efficiently, and the cost may increase.

(Quicklime surface treated with hydrophobic coating)
The method for producing quicklime surface-treated with a hydrophobic coating agent is not particularly limited as long as it does not adversely affect the excrement treating agent of the present invention and the excrement treating method using the same. Specifically, for example, a method of mixing quick lime powder and a coating agent at a temperature higher than the melting point of the coating agent, or a quick lime powder held at a temperature slightly lower than the melting point of the coating agent, with stirring, the coating agent Preferably, a method of spraying the melt of is used. Moreover, since the said quicklime is normally manufactured by baking calcium carbonate, after cooling the quicklime obtained by baking to predetermined | prescribed temperature, it is also preferable to attach | subject to the said surface treatment method. The surface-treated quicklime may be used in combination with two or more kinds of quicklime that have been surface-treated using different amounts of coating.

  Although the shape of the said surface-treated quicklime is not specifically limited, It is preferable that it is a granular form. The average particle diameter is preferably in the range of 0.1 μm to 5 mm, more preferably in the range of 0.5 μm to 2 mm, and particularly preferably in the range of 1 μm to 1 mm.

Or it is preferable that it is a substance which generate | occur | produces heat | fever by reaction with slaked lime (Ca (OH) 2) etc., and can supply the calorie | heat amount required for melting | fusing of the said coating material. Specific examples of such exothermic agents include quick lime, powdered aluminum, aluminum oxide, magnesium oxide, and anhydrous magnesium chloride. These compounds may be used alone or in combination of two or more.

  Among these, it is preferable to use quick lime from the viewpoint that it can also contribute to excrement treatment. The amount of quicklime used in this case is preferably in the range of 20 to 200 parts by weight with respect to 100 parts by weight of the surface-treated quicklime, and 25 to 150 from the viewpoint of obtaining a processed product as a powder. The range is more preferably in the range of parts by mass, and particularly preferably in the range of 25 to 100 parts by mass. When the amount of quicklime used is less than 20 parts by mass, the calorific value is small, and the surface-treated quicklime cannot be activated efficiently, so that there is a possibility that the excrement treatment time becomes long. On the other hand, when the amount of quicklime used exceeds 200 parts by mass, the surface-treated quicklime is immediately activated by the excessive amount of heat generated, and a lump may be formed, leaving unreacted material remaining.

  However, the amount of the exothermic agent used is not limited to the amount used when the exothermic agent is quicklime, and can be appropriately adjusted based on the type and amount of the coating agent, the type of exothermic agent, and the like.

  Moreover, when using quicklime as a heat generating agent, although a shape is not specifically limited, It is preferable that it is a granular form. Moreover, the average particle diameter is preferably 0.1 μm to 5 mm, and more preferably 0.5 μm to 2 mm.

  The quicklime surface-treated with the hydrophobic coating agent described above does not cause aggregation due to reaction with moisture during manure treatment and can be efficiently pulverized under the mixing conditions during manure treatment, or the hydrophobic By the physical and / or chemical mechanism as described in the section of the protective coating agent, the coating agent is peeled from the surface of the quicklime surface-treated with the coating agent, and the reaction between the quicklime and the excrement where the active surface is exposed, In the case where the amount of heat necessary for melting the coating agent present on the surface of the surface-treated quick lime used in the present invention can be supplied, the surface-treated quick lime can be used as a heat generating agent.

(Water absorbing material)
It is preferable that the excrement treating agent of this invention further contains a water absorbing material. The water-absorbing material that can be used in the present invention is a viewpoint that controls the reaction between active quicklime and manure, that is, the moisture contained in the manure reacts with the active surface of quicklime at a time to produce agglomerates by aggregation. From the viewpoint of suppressing the remaining unreacted excreta. The water-absorbing material is not particularly limited as long as it does not adversely affect the manure treatment agent of the present invention and the manure treatment method using the same, and a known substance can be used. It is preferable that the water | moisture content which it did is the substance which can react in contact with the active surface of quicklime. Examples of the water absorbing material include sawdust, water-soluble paper, fiber bundle, nonwoven fabric, peat moss, and grass charcoal. These may be used alone or in combination of two or more. The amount of the water-absorbing material used can be appropriately adjusted depending on the type and shape of the water-absorbing material and the amount of water contained in the manure that is the object to be treated. Is preferably in the range of 2 to 6 parts by mass.

(Additive)
The manure treating agent of the present invention further contains other additives in place of or in addition to the water absorbing material, as long as the manure treating agent of the present invention and the manure treating method using the same are not adversely affected. Also good. Examples of such additives include fragrances, deodorants, or deodorizers from the viewpoint of odor control; hydrophilic organic compounds such as alcohols from the viewpoint of improving the wettability of the surface-treated quicklime to water, or Surfactant; From the viewpoint of controlling the water content in manure, examples thereof include desiccants such as silica gel and anhydrous sodium sulfate, and water retention agents such as water-absorbing resins. These additives may be used alone or in combination of two or more.

  Examples of the fragrances include lemon oil, lemon grass, cinnamon oil, lavender oil, and vetiver.

  Various surfactants can be used as the surfactant, and specific examples thereof include, for example, polyoxyethylene alkyl ether, polyoxyethylene alkyl phenyl ether, polyoxyethylene monofatty acid ester, polyoxyethylene alkyl ester, Nonionic surfactants such as oxyethylene difatty acid ester, polyoxyethylene propylene glycol fatty acid ester, polyethylene sorbitan monofatty acid ester, glycerin monofatty acid ester; alkylbenzene sulfonate, alkyl sulfosuccinate, alkyl sulfate, polyoxyethylene alkyl sulfate Anionic surfactants such as aryl sulfonates; long-chain primary amine salts, dialkyldimethylammonium salts, alkyltrimethylammonium salts, benzylates Ammonium chloride, alkylpyridinium salts, benzalkonium chloride, cationic surfactants such as benzethonium chloride; or alkyldiaminoethylglycine hydrochloride, and amphoteric surfactants such as hydrochloric alkylpolyaminoethylglycine is.

  Further, a sachet made of a water-soluble resin, a sachet made of water-soluble paper, or a sachet made of a water-degradable nonwoven fabric, which can be used when adding the sewage treatment agent to sewage, is also included in the sewage treatment agent of the present invention. It can be contained as an additive.

(Adjustment method of manure treatment agent)
The method for preparing the manure treatment agent of the present invention is not particularly limited. For example, quick lime surface-treated with a hydrophobic coating agent and a heat generating agent are mixed, and if necessary, a water absorbing material and / or a desired addition. The method etc. which mix an agent are mentioned.

  The surface-treated quicklime is coated with a hydrophobic coating agent, so that not only the moisture resistance of the resulting excrement treatment agent is increased, but also a reaction that does not cause a reaction immediately even if it comes into contact with excrement during the excrement treatment Since it has a retarding property, it does not immediately come into contact with the active surface of quicklime to produce a lump or the like. Therefore, manure and the manure treatment agent of the present invention can be mixed uniformly. However, when a higher fatty acid, particularly a higher fatty acid having 15 to 26 carbon atoms, is used as the coating agent, the hydrophobicity is higher, and mixing with feces and urine containing a large amount of water may make stirring difficult. In such a case, from the viewpoint of facilitating the stirring of the powder, an additive such as a surfactant or a salt of a higher fatty acid having a relatively low hydrophobicity, particularly a higher fatty acid having 8 to 14 carbon atoms. You may use it, adding a salt further to the excrement processing agent.

  The method for adding the manure treatment agent to manure is not particularly limited, but from the viewpoint of ease of handling and the like, for example, the manure treatment agent is previously put in a sachet, and the sachet is left as it is during the manure treatment. A method of adding to manure is preferable. The wrapping bag in this case may be a wrapping bag made of a water-soluble resin, a wrapping bag made of water-soluble paper, or a wrapping bag made of a water-degradable nonwoven fabric so that the sewage treatment agent is efficiently diffused into the urine during sewage treatment. preferable. In addition, it is preferable to preserve | save the said excrement processing agent including these aspects on moisture and water resistant conditions.

  FIG. 5 is a schematic view showing a state in which the manure and manure treatment agent in the toilet pack are stirred and mixed, and a spatula.

  Referring to FIG. 5A, the manure processing apparatus 1 of the present embodiment is provided with a spatula 70 for stirring and mixing the manure received in the toilet pack 10 and the manure processing agent 20 as an accessory. Yes. The spatula 70 is formed of, for example, cardboard or corrugated cardboard, and may be an independent fixture, or may be provided as a spatula portion 71 in a part of the lid 80 or the outer container 40 described later. (See FIG. 6). As shown in FIG. 5B, for example, the spatula portion 71 is cut off from the lid 80 or the like during use, and a cut is made along the perforation 72 of the cut off spatula portion 71 to form a pair of fold lines 73. When bent upward (inward), a spatula 70 as shown in FIG. 5 (a) is produced. Thus, since the spatula can be manufactured easily and easily, the convenience is improved.

  FIG. 6 is a perspective view showing an outer container constituting the processing container in the present embodiment. FIG. 7 is a schematic view showing a state in which the outer container in the present embodiment is folded. FIG. 8 is a perspective view showing a state in which the disposal bag is installed as an interior material in the outer container in the present embodiment. FIG. 9 is a perspective view showing a state where the upper opening of the processing container is covered with a lid.

  With reference to FIG. 6, the processing container (processing tank) 30 is comprised from the outer container 40 and the interior material 50 mounted by this. The outer container 40 is, for example, a box-shaped container having a rectangular bottom surface and an open upper surface (a hollow rectangular parallelepiped shape having an open upper surface). The shape of the container is not limited to this, and may be other shapes such as a hollow cube whose upper surface is open (for example, about 30 cm on a side), a bottomed cylindrical body, and the like. The outer container 40 is formed into a container shape by assembling a combustible material, and the outer container 40 is formed of the combustible material so that it can be disposed of as an incinerator after a disaster or the like has passed. Because.

  Examples of combustible materials include corrugated cardboard, cardboard, or wood, but in consideration of foldable storage and weight reduction, the corrugated cardboard is assembled like the outer container 40 of the present embodiment. It is preferable to mold. Referring to FIG. 7, the outer container 40 of the present embodiment is formed of a cardboard box. Therefore, if the bottom portion 45 is disassembled, the outer container 40 can be easily folded into a flat plate shape and has excellent storage properties when not in use. Yes. And if the bottom part 45 is couple | bonded with a gum tape, a stapler needle, etc., it can assemble easily. In addition, if thick corrugated paper is used as a combustible material, a heat insulating effect can be obtained.

  The interior material 50 housed in the outer container 40 is formed of a material having heat resistance at a temperature of 80 ° C. or higher and 450 ° C. or lower. With reference to FIG. 8, the interior material 50 of the present embodiment is formed of, for example, a flame-retardant disposal bag that can be attached to and detached from the outer container 40. The disposal bag 50 is inserted and arranged inside the outer container 40, and is disposed so that its opening edge is folded outward along the upper edge of the outer container 40. The reason why heat resistance is required at a temperature of 80 ° C. or higher is that the inside of the system reaches 80 ° C. to 95 ° C. due to the hydration reaction of the excrement treating agent described later. The reason why heat resistance is required at a temperature of 450 ° C. or lower is that the feces and urine treatment agent described later is a powder, so that heat is not easily transferred within the system, and locally 200 ° C. to 400 ° C. when heat is generated by the hydration reaction. This is because it is estimated that

  As the disposal bag 50, a material having flame resistance (heat resistance) at a temperature of 80 ° C. or higher and 450 ° C. or lower, for example, an aluminum vapor deposition film material in which an aluminum foil is vapor-deposited on air foam, polyester, nylon, polyethylene or the like, Nylon vapor-deposited vinyl material, fiber material such as glass, ceramic, silica, alumina, resin laminated paper such as polyethylene terephthalate (PET), resin foam insulation paper such as polyethylene (PE), embossed paper sleeve, polyethylene (PE) Resin processed materials such as polypropylene (PP) and ethylene vinyl alcohol copolymer (EVOH) can be used, and these can be used to form a bag. The disposal processing bag 50 preferably has a flexibility that easily follows the inner shape of the processing container 30. For example, a plastic bag in which nylon is vapor-deposited at least on the inner surface is preferably used.

  By adopting a flame-retardant disposal bag as the interior material 50, the bag 50 is removed from the outer container 40 while the treated manure, toilet pack 10 and the like are accommodated in the disposal bag 50, and is hygienic. The outer container 40 can be used repeatedly. Note that the upper opening of the outer container 40 in which the disposal bag 50 is disposed is covered with a lid 80 described later.

  The outer container 40 described above is formed only of a combustible material (corrugated cardboard), but is not limited to this, and the inner surface 41 of the outer container 40 is further heat resistant at a temperature of 80 ° C. or higher and 450 ° C. or lower. You may laminate the material which has. Examples of heat-resistant materials include materials in which a metal foil such as a heat-resistant resin or aluminum foil is attached to the surface of flame retardant paper, or a metal such as aluminum on the surface of a resin material such as air foam, polyester, nylon, or polyethylene. The metal vapor deposition film material which vapor-deposited, the metal foil film material which stuck metal foils, such as aluminum foil, on the surface of these resin materials, and flame-retardant resin materials, such as a nylon vapor deposition vinyl material, etc. are mentioned. When the heat-resistant material is laminated on the inner surface 41 of the outer container 40 in this way, the heat-resistant material layer serves as the interior material 50, so that the outer container can be used without using the disposal bag 50. It is also possible to use 40 alone. If the disposal bag 50 is further housed in the outer container 40 in which the heat-resistant materials are laminated, the heat resistance of the processing container 30 is ensured.

  Referring again to FIG. 6, the processing container 30 includes a lid 80 that covers the upper opening, and a rectangular vent 81 is opened at the center of the lid 80. The vent 81 is an opening for releasing the vapor filled in the processing container 30 due to the exothermic reaction of the excrement treating agent 20. When the lid 80 is attached to the upper part of the processing container 30, the lid 80 It is sufficient to have an opening area that does not lift up due to vapor pressure.

  As described above, the lid 80 is made of, for example, a combustible material such as corrugated paper, cardboard, or wood in order to finally allow disposal as an incinerated product. In the present embodiment, the outer container 40 is formed of a combustible material and a common material (corrugated cardboard). The lid 80 may be provided with the above heat resistant material.

  Further, activated carbon 92 that adsorbs odor gas generated from the inside of the processing container 30 and a water absorbing material 91 that prevents moisture absorption of the activated carbon are mounted on the upper surface of the lid 40. The water absorbing material 91 is a sheet-like member that absorbs moisture like a sponge, and is formed in a square shape so as not to block the vent hole 81 of the lid 80. Examples of the material include a porous acrylic resin and a polymer hygroscopic agent. As a condition, a material that is not altered by the heat of water vapor is desirable. The activated carbon 43 is accommodated in a bag body such as a nonwoven fabric, and the bag body is formed in a square shape or a rectangular shape so as not to block the vent hole 81 of the lid body 80. Each of the water absorbing material 91 and the activated carbon 92 may be one piece or divided into a plurality of pieces, but it is preferable that the water absorbing member 91 and the activated carbon 92 are arranged so as not to block the vent hole 81 of the lid 80. If the water absorbing material 91 is arranged under the activated carbon 92 in this way, it is possible to prevent the pores of the activated carbon 92 from being initially blocked with water vapor and reducing the adsorption of odorous gas.

  The arrangement of the water absorbing material 91 and the activated carbon 92 is not limited to the present embodiment, and the water absorbing material 91 and the activated carbon 92 may be installed in this order from the bottom on the top plate inner surface (ceiling surface) of the lid 80. In addition, an inner lid (not shown) is provided at the upper end opening of the outer container 40 separately from the lid 80, a water absorbing material 91 is placed on the inner lid, and activated carbon 92 is placed on the water absorbing material 91.

(Manure disposal method)
Next, an embodiment of the excrement disposal method according to the present invention will be described with reference to FIGS.

  In the excrement disposal method of this embodiment, first, as described above, excrement is received in the toilet pack 10 that is folded into a container shape. The toilet pack 10 is normally stored in a folded state as shown in FIG. 1E, and is taken out from a storage location or a disaster bag at the time of a disaster. Then, as shown in FIG. 2, the triangular holding parts 11 and 12 located on both outer sides of the toilet pack 10 are picked with fingers, the opening edge F is expanded to the left and right, and is formed into a container shape. It is held by a toilet seat 61 of an existing toilet seat opening / closing toilet (Western style toilet) 60 using the parts 11 and 12.

  Specifically, as shown in FIG. 2, with the toilet seat 61 of the toilet bowl 60 opened upward, the container portion 13 of the toilet pack 10 is accommodated in the toilet bowl 60, and is held by being picked up with fingers and projecting left and right. The parts 11 and 12 are placed on the left and right edges of the toilet 60. Next, as shown in FIG. 3, if the toilet seat 61 is closed, the holding portions 11 and 12 can be held between the left and right edges of the toilet 60 and the toilet seat 61.

  The toilet pack 10 can be used alone without being installed in an existing toilet bowl, and cannot be held, but can be installed in a toilet bowl (Japanese style toilet bowl) that does not have a toilet seat. I do not care.

  Since the toilet pack 10 has water repellency at least on the inner surface that receives the manure, the water of the manure received in the toilet pack 10 does not leak out of the toilet pack 10. Further, the outer surface of the toilet pack 10 may be subjected to a water repellent treatment such as a resin coating. If configured in this way, even if it contacts the water accumulated in the toilet 60, the toilet pack 10 Will not be torn.

  The processing container 30 shown in FIG. 8 is preferably installed outdoors where rain dew can surpass, such as a veranda, a bathroom, and the eaves. After receiving the manure in the toilet pack 10, it moves to the installation location of the processing container 30, opens the bag body 21 sealed with the manure treating agent 20 as shown in FIG. Add agent 20. Feces and urine may be stool alone or a mixture of stool and urine.

  Then, as shown in FIG. 5A, the feces and urine treatment agent 20 in the toilet pack 10 are stirred and mixed using a spatula 70 or a scoop. Immediately after mixing of the excrement treating agent 20, the mixture of the excrement and the excrement treating agent 20 is put into the processing container 30 together with the toilet pack 10, and the excrement of the excrement is exothermed.

  The use amount of the excrement treating agent 20 may be appropriately measured. However, in consideration of the convenience of use, the use amount suitable for one or several defecations may be subdivided in the bag body 21 and sealed. preferable. Specifically, it is preferably in the range of 1 to 200 parts by mass, more preferably in the range of 10 to 150 parts by mass, and 80 to 120 parts by mass with respect to 100 parts by mass of manure that is the object to be processed. More preferably it is. When the amount used is less than 1 part by mass, the urine adsorption process cannot be performed sufficiently, and there is a possibility that unreacted substances remain. On the other hand, when it exceeds 200 mass parts, there exists a possibility that processing efficiency may worsen.

  As described above, the processing container 30 of the present embodiment is composed of the outer container 40 and the interior material 50 installed in the outer container 40, and can be attached to and detached from the outer container 40 as the interior material 50. A disposal bag 50 having flame retardancy (heat resistance) at the following temperatures is employed. As shown in FIG. 8, the disposal bag 50 is disposed as an interior material inside the outer container 40, and the opening edge is folded outward along the outer edge of the upper end of the outer container 40 so as to be disposed. A mixture of manure and manure treatment agent 20 together with the toilet pack 10 is put into the treatment bag 50.

  After the mixture of the toilet pack 10 is put into the processing container 30 (the outer container 40 in which the disposal bag 50 is disposed), the upper opening is covered with the lid 80, and the manure and the stool treatment agent 20 are contained in the processing container 30. The hydration reaction (exothermic reaction) with is promoted. That is, the exothermic agent generates heat due to the reaction with manure, melts the surface-treated quicklime coating to expose the active surface of quicklime, and the quicklime further reacts with moisture in manure to generate heat and produce a reaction. The processed substance is obtained as a powder by adsorbing feces and urine by calcium hydroxide as a substance. The treated powder thus obtained has hydrophobicity due to the effect of the coating agent, and does not return to the original form of manure by mixing of water such as rain water. Moreover, since the inside of the above treatment system reaches 80 to 95 ° C. and is strongly alkaline, it can sterilize the bacteria in manure and suppress the generation of malodor due to the decay of the treated material. be able to.

  Since the flame-retardant disposal bag 50 disposed in the outer container 40 has heat resistance at a temperature of 80 ° C. or higher and 450 ° C. or lower and acts as a heat insulating material for the outer container 40, Even if the manure treatment agent 20 is mixed with the manure received in the container and the mixture is put into the disposal bag 50 together with the toilet pack 10, the treatment container 30 is burnt by the reaction heat due to the exothermic reaction of the manure treatment agent 20. Holes can be prevented from being ignited or ignited. In addition, if the raw material which has heat resistance in the temperature of 80 to 450 degreeC is laminated | stacked also on the inner surface 41 of the outer container 40, the outer container 40 can be reliably protected from reaction heat. In addition, when a heat-resistant material is laminated on the inner surface 41 of the outer container 40, the layer of the heat-resistant material functions as the interior material 50. Therefore, without using the flame-retardant disposal bag 50, the outer container It is also possible to use 40 alone.

  The processing container 30 is filled with steam due to the exothermic reaction of the excrement treating agent 20, but the vent 81 is opened at the center of the lid 80, so that the steam can escape to the outside of the processing container 30. The lid 80 is not lifted by the vapor pressure. An activated carbon 92 that adsorbs odorous gas generated from the inside of the processing container 30 is mounted on the upper surface of the lid 80. A water-absorbing material 91 is disposed under the activated carbon 92, and it is prevented that the pores of the activated carbon 92 are initially clogged with water vapor and the odor gas adsorption is reduced.

  After the heat generation process in the processing container 30 is completed, the processed product (processed excrement etc.) is discarded. In the present embodiment, since the disposal bag 50 is detachably installed in the outer container 40, the waste bag 50 is stored in the disposal bag 50 with the heat-treated feces and urine, the toilet pack 10 and the like stored therein. If it is removed from the outer container 40 and its opening is closed, the treated product (treated manure, etc.) can be discarded in a sanitary manner, and the outer container 40 can be used repeatedly without being contaminated during a disaster. .

  After the disaster has passed, the outer container 40 can be folded and stored as shown in FIG. When the outer container 40 is discarded, the constituent material is a combustible material such as corrugated paper, and can be incinerated.

  As described above, according to the excrement disposal apparatus 1 and the excrement disposal method of the present embodiment, a disposable toilet pack is placed in an existing toilet bowl, receives excrement, and, for example, quick lime and heat generated by surface treatment with a hydrophobic coating agent The fecal urine heat treatment can be performed in a processing container placed outdoors or the like using the excrement treating agent containing the agent. And since at least the inner surface of the container-like toilet pack 10 that receives the manure has water repellency, the moisture of the manure received in the toilet pack 10 does not leak out. In addition, since the inside of the processing container 30 has heat resistance, even if the manure treatment agent 20 is mixed with the manure received in the toilet pack 10 and the mixture is put into the processing container 30 together with the toilet pack 10, manure It is possible to prevent the processing container 30 from being burnt by a reaction heat due to an exothermic reaction of the processing agent 20 to be pierced or ignited. Further, when the toilet pack 10 is inserted, if the flame retardant disposal bag 50 is detachably installed in the outer container 40, the disposal bag 50 is removed after the excreta treatment, and the contents of the bag 50 are discarded. Can be very hygienic.

  The present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the claims. For example, the excrement treating agent is not necessarily limited to that of the above embodiment, and any form of excrement treating agent such as an excrement treating agent composed of quick lime can be used.

  Further, for example, it is desirable to lay a reinforcing sheet on the inside of the toilet pack 10 shown in FIG. 1 from the viewpoint of improving heat resistance.

  FIG. 10 is a development view of the reinforcing sheet laid in the toilet pack. The reinforcing sheet 14 shown in FIG. 10 is formed by sticking a heat-resistant material to at least one surface of a combustible material (corrugated cardboard). The material is preferably a material having heat resistance at a temperature of 80 ° C. or higher and 450 ° C. or lower. Examples of heat-resistant materials include materials in which a metal foil such as a heat-resistant resin or aluminum foil is attached to the surface of flame retardant paper, or a metal such as aluminum on the surface of a resin material such as air foam, polyester, nylon, or polyethylene. The metal vapor deposition film material which vapor-deposited, the metal foil film material which stuck metal foils, such as aluminum foil, on the surface of these resin materials, and flame-retardant resin materials, such as a nylon vapor deposition vinyl material, etc. are mentioned. The reinforcing sheet 14 is disposed so as to be laid in the toilet pack 10 after being folded along the folding line L5. The reinforcing sheet 14 includes side surfaces 141 and 142 for reinforcing side portions inside the toilet pack, and front and rear surfaces 143 and 144 for reinforcing front and rear portions inside the toilet pack.

  However, in order to improve the heat resistance of the toilet pack 10, the outer side of the toilet pack 10 may be covered with a bag made of the same material as the reinforcing sheet 14.

  Further, the toilet pack 10 is manufactured, for example, manually by the folding procedure shown in FIG. 1, but a box-type toilet pack 15 as shown in FIG. 15 is used to promote automation of toilet pack manufacturing. Also good.
