Description

[Detailed description of the invention] Animal excrement processing methods and equipment The present invention relates to a method for preparing granular fertilizer from animal waste. The present invention further relates to animals. Processing of animal excreta to process the excreta of organic compounds, e.g. amino acids , especially a method for synthesizing L-lysine and L-methionine from animal excrement, animal excrement methods for purifying volatiles and organic compounds from animal waste, and special methods for treating animal waste. Special method and apparatus.

In animal waste processing methods, as much of the product as possible is separated from the animal waste. It is very important to. In these processing methods, the solid content from animal excrement Maximum attention should be paid to the separation of fertilizers, and this solid content should not be used in place of synthetic fertilizers after drying. It will be done.

A known method for processing animal excrement is the so-called bromost method, which begins with biogas processing. Animal waste is fermented in a fermenter to generate . The solids are then fermented After being removed from the animal waste and dried as an animal waste cake, it forms a useful product. Ru. Fermentation results in animal waste cake containing relatively small amounts of organic compounds. . These organic compounds are incorporated into fertilizers along with mineral nutrients, phosphorus, potassium, etc. , makes a better difference than synthetic fertilizers.

As will be described later, the present invention allows the amount of fertilizer administered to be reduced compared to that of synthetic fertilizers. The aim is to obtain agriculturally improved fertilizers compared to synthetic fertilizers.

According to the present invention, in order to prepare granular fertilizer from animal excrement, (1) animal excrement is Acidified: (ii) dehydrating the acidified animal waste and evaporating the liquid carrier; (i) ii) Granular fertilizers from animal excreta, including those that form granules from the resulting fertilizers; This invention relates to a method for preparing a food.

Preferably already on the farm by acidifying the animal waste. Biological decomposition of organic matter present in the excreta is virtually avoided. Therefore, the original Fertilizers produced by Ming have a relatively high percentage of organic matter, generally more than 30% to 40% , preferably about 50% organic matter. Ammonia emissions are significantly reduced.

For example, animal waste may be acidified using nitric acid. However, it is safe From this point of view, sulfuric acid is preferred as the formation of explosive ammonium nitrate is thereby avoided. It will be done. When using sulfuric acid for acidification, the active nutrients nitrogen, phosphorus and potassium are added to the fertilizer. The composition contained in the material is 9-3-6. When sulfuric acid is used for acidification, these activities are The composition of nitrogen, phosphorus and potassium, which are important nutrients, is 6-3-6. Agricultural law study The results show that the fertilizer has a phosphate effect equivalent to that of synthetic fertilizers, while nitrogen The effectiveness (inorganic and organic nitrogen) was found to be about 70% of that of synthetic fertilizers.

Preferably, acidification is carried out using a mixture of nitric acid and sulfuric acid. Because fertilizer farming The commercial value is improved under special conditions by acidification using this mixture. . For example, acidification can be done using a mixture with a nitric acid:sulfuric acid ratio of 30-50:70-50. You can also do it later. More preferably the nitric acid:sulfuric acid ratio is 35-45:65-5 It is 5.

Added by the seed layer of animal excrement and by the solids content of animal excrement The amount of acid is generally p)! :3. 5-5. 5, more preferably 4-5, especially 4.　 This amount is sufficient to cause an increase of 1-4°3. Generally the amount of acid added is 1-10% by weight based on the weight of the excreta. More preferably, the amount added is 1-5% by weight, usually 3% by weight.

Additives are used to match the active nutrients and nitrogen, phosphorus and potassium composition of the fertilizer. May be added to fertilizers. Additives include sulfuric acid, nitric acid and potassium salts.

Since the obtained fertilizer is usually in powder form, it is preferable to form it into granules. Fertilizer in principle The material naturally becomes granular, but when the preferred granulation enhancer is added, narrow granule sizes are formed. Granulation within the distribution can be achieved. These granulation accelerators include, for example, chocolate. Contains oak, molasses, carboxymethylcellulose and bentonite. Actually this These additives are binders that bind and set the granular fertilizers together.

To avoid the release of large amounts of air when drying the formed condensate, use vacuum cooling. Preferably, the condensate is dried using Therefore, purify the air if necessary. In addition, the emission of odors must be sufficiently reduced, which must be emitted. This is possible by adequately adjusting the amount of air that is Condensed water may be purified at a relatively low cost.

Preferably, the animal waste is processed using the so-called greenfield process (US-3,855°). 079, US-4,270,974 and US-4,608,120) i::shita Cut and dehydrate. According to this known method, non-volatile oil is added to animal excreta. The oily slurry formed is dehydrated by thermal evaporation and then the oil is heated to 140-1 The solids are removed by volatilization at a temperature of 60°C. This high distillation temperature It kills the weed seeds present in the excrement and sterilizes it for long-term use of fertilizer or granular fertilizer. Allows for temporary storage. Another important advantage is that all bacteria are killed during the sterilization process. In this process, bacteria contained in animal excrement, such as pig fever bacteria, are treated. Ru. From this point of view, hair that may be present in animal excrement is granulated and then passed through the sieve. It can be easily removed by cleaning.

The particles formed are more than 80%, preferably 85%, more preferably 90% It has a solid content of Generally the particles are: NH, -N 1-3% by weight No3N1.53.5% by weight Total N 5-9% by weight Total P2O3 2-5% by weight Total 203-10% by weight including.

The method of the invention can be used to collect waste from many types of animals, such as cattle, pigs, poultry, etc. It may also be used in relation to generated animal waste. Animal excrement generally contains solids. Although the amount may be higher than 7%, according to the method of the invention, higher solids contents, e.g. It is particularly preferred that the Delicious. Therefore, during the animal excrement processing process, a smaller amount of animal excrement is has the advantage of being transported. In addition, the addition of acids on the farm The occurrence of monia is significantly reduced.

Below, the agricultural value of modified fertilizers will be explained in comparison with that of synthetic fertilizers.

acid using nitric acid or a mixture of nitric acid and sulfuric acid (40/60 (w/w)) before storage. The excrement of the pigs, which have been sexified and thereby lowered the pH of the excrement to 4.2, is passed through a sieve. Remove bulky waste. Acidified animal excrement is converted into water-insoluble boiling point 180 Mixed with liquid paraffin at °C.

This mixture of animal waste and paraffin was dehydrated by distillation. The generated steam condensed in a condenser. A concentrated liquid mixture of animal waste and paraffin is heated in a container. The paraffin was removed by distillation at about 180-190°C. if necessary Residual paraffin may also be removed from the resulting fertilizer by steam stripping. stomach. After drying the fertilizer, the product is a residue with a moisture content of about 1.5% and a particle size of less than 100 μm. Fertilizer with the above has about 28% refined product. Bulk weight is approximately 500g/l .

The fertilizer is then granulated. If necessary, add additives and granulation accelerators to the granulation drum. In addition, the fertilizer is divided into particles with a particle size distribution in the range of 0.5-8 mm. Granulate.

The particles are then sieved to remove hair and the like. Finally, classify the particles.

The particles formed typically have a moisture content of 25-35%, preferably 32-36%.

The granulation temperature depends on the granulation method employed, but is, for example, between 80 and 100°C.

The particles are then added to a vacuum cooling unit, the pressure is reduced to approximately 20 mBar, and the granulation temperature is By lowering the temperature, water evaporates. If the temperature of the particles to be dried is If it is not high enough, excess steam may be added to adjust the particle conditions. this Employing vacuum cooling technology can substantially reduce the amount of air required to dry particles. while providing the particles with optimal wear resistance, hardness and quality. ten particles Preferably, the particles have a diameter of 1-gmm for faster drying. Finally, if you If necessary, the particles may be post-dried.

The table below shows a number of fertilizers using fertilizers acidified using a 40/60 nitric/sulfuric acid mixture. shows a granulation experiment.

Animal excrement acidified with nitric acid (hereinafter referred to as fertilizer N) and 40/60 nitric acid/sulfuric acid Granular fertilizer obtained from animal excrement acidified with a mixture (hereinafter referred to as fertilizer S) The agricultural value of fertilizers will be investigated using synthetic fertilizers as a comparison target.

Table 2 shows the composition of the granular fertilizer used.

Tests were conducted on clay and sandy soils. Grain on clay soils for consumer use It is a potato, and in sandy soils it is an industrial potato. in each type of soil , using five types of fertilizer N processes, changing to O-280 k g/h a per year. Ta.

Based on soil tests clay soil fertilizer contains 220 kg nitrogen and for sandy soils 210kg nitrogen is recommended.

During the growing season, the grain showed very rapid color changes. grown on fertilizer products On average, grains fertilized with 140 kg/ha of nitrogen had a color comparable to that of grains fertilized with 140 kg/ha of nitrogen. 1 and 2 used synthetic fertilizers (0-280 kg/ha), with fertilizer N and fertilizer S. Clay for nitrogen content (solid content %) and nitrogen intake (kg/ha) after nitrogen administration Field test results on soil are shown. Figures 3 and 4 show similar fi elds on sandy bedding. The field test results are shown below.

From these results, the inorganic nitrogen dosage of 100 kg/ha in the form of fertilizer is the same as that of synthetic fertilizer. It can be seen that this corresponds to a nitrogen dosage of 140 kg/ha. Therefore, soil mineral The physical burden can be reduced.

In a test on clay soil using consumer potatoes, fertilizer N and fertilizer S were tested. When used, the yield of potatoes in tons/bB is as follows: Synthetic fertilizer (59.1 ton/h) 42.2 respectively compared to when using a). and 67.2ton/ha increased to

For industrial potatoes grown on sandy soil, synthetic fertilizers (46,0 t o n/h a ) was increased to 48.4 ton/ha, respectively.

The weight of grain per unit price is compared to 67.6 tons/ha when using synthetic fertilizer. They were 67.8 and 66.8 ton/ha, respectively. Furthermore, this Their tests showed that the nitrogen present in fertilizers was extremely active, which led to the release of mineral nitrogen. This shows that not only elementary nitrogen but also organic nitrogen is active. This is the fertilizer of the invention A smaller dosage is required to obtain the same yield compared to that of synthetic fertilizers. In terms of the economics of the animal excrement processing process, it is important to extract as much as possible from animal excrement. It is important to separate many useful products. These useful products are Not only the selling price but also the cost paid to treat the waste that is discharged into the environment after treatment. Purpose is also important.

The process for processing animal excreta should be carried out if the formation of useful products is maximized and If the formation of waste is minimized, then from an economic point of view the price effect is simply too much. Ginai. This must ensure that the waste composition can be treated at the lowest possible cost. It means that it must be done. These processing costs are the total cost of animal waste. Further reductions are possible if products that can contribute to the cost effectiveness of the processing process are obtained during processing. It is. In this case, the generation of biogas is particularly noteworthy.

First, the known processing process for animal excrement is the so-called Bromest method, in which The animal waste is fermented in a fermenter prior to further processing, producing biogas. bring to life The solids are then separated from the fermented animal waste and, after drying, Get excrement cake. As a result of fermentation, the waste contains small amounts of organic matter but no inorganic products. The amount of waste generated is relatively high, which makes the cost of disposing of the waste it generates relatively high. . Furthermore, since the entire volume of animal waste is in principle subjected to fermentation, Takes bulk over a long period of time.

A second known processing step is the so-called greenfield process (US-3,855,0 79, US-4,270,974,'US-4.608,120). this According to known processing steps, a liquid organic carrier is added to the animal waste, which is then added to the animal waste. The mixture of excreta and liquid carrier is dehydrated by evaporation and the vapor formed to obtain a condensate. The components of this condensate are only disposed of in the environment after treatment. Ru.

Biological treatment of this condensate appears virtually impossible due to their composition.

First, this condensate contains very small amounts of nutrients and minerals essential for biological decomposition. Contains only

Second, this condensate contains toxic components derived from animal waste, such as ammonia. and phenolic components.

Third, condensate has a destructive effect on biological degradation processes or Contains used organic liquid carrier residues that will discharge biomass from the plant. .

However, surprisingly, this condensate is considered to make biological treatment expensive. Despite its composition, this condensate was continuously treated anaerobically and then aerobically. It was found that it can be treated relatively cheaply if it is subjected to sexual treatment.

That is, the present invention: i) adding a liquid organic carrier to the animal waste; ii) adding the liquid organic carrier to the animal waste; 1ti) condensing the resulting vapor; iv) subjecting the condensate to anaerobic treatment; and V) subjecting the effluent from the anaerobic treatment to The present invention relates to a method for processing animal excrement, including a step of pneumatically treating it.

If the animal excrement is collected, preferably before its concentration, but more preferably Acidification of animal waste immediately after its release, i.e. on the farm, reduces the amount of ammonia in animal waste. It is possible to maintain a high temperature and avoid the release of ammonia. Desirable because of low pH Bad fermentation produces as little as possible, thereby reducing the amount of organic matter present. This organic matter, which has no solution and enters the condensate via the vapor phase, is an essential source of carbon in it. can function as Carbon source supplementation is thereby reduced to a considerable extent. can be

In a preferred embodiment, a portion of the effluent from the anaerobic process is recycled and condensed for processing. At the beginning of the anaerobic treatment, the pH of the condensate is adjusted to the required pH for the anaerobic treatment. Addition of a base to increase H may be omitted. In either case, anaerobic treatment The effluent has a higher pH due to the decomposition of fatty acids present in the condensate. . Preferably 20-90%, more preferably 30-80%, even more preferably 4 Recycle 0-80% of the effluent.

anaerobic treatment of new biomass to enable it to form to a sufficient extent. It is recommended to add a nutrient preparation agent, e.g. precision or vinasse (distillation residue a), to the condensate. It will be done.

It has been found that condensed compositions first require nitrogen. Therefore, it requires nitrogen If necessary, add nutrient preparation to provide nitrogen requirements. This amount is nitrogen At least 50 g/m3. Preferably 60 g/m3. better Preferably, it is 70-80 g/m'te.

Another necessary nutrient source is phosphorus. If phosphorus is required, nutrients for it For example, the preparation agent can be added at least 10 g/m3, preferably 15 g/m3 to the required amount of phosphorus. g/m", more preferably 20 g/m3.

When, as a result of its composition, the condensate needs trace elements, this nutrition The formulation preferably also contains trace elements. When trace elements are low, nutritional preparations are Contains iron, nickel, cobalt, manganese, zinc, molybdenum, and copper Good too.

Micronutrients if needed, e.g. sulfur, potassium, calcium, magnesium may be added.

at a temperature of 30-40°C, preferably 35-40°C, and a pH of 6-8, preferably 7. When treated anaerobically, the C0D (chemical oxygen demand) treatment yield is preferably 80% or more. preferably 85% or more, more preferably 90% or more, for example 90-95%.

Condensate is essentially free of sugars, amino acids, and alcohol, but is primarily volatile. contains hydrolytic fatty acids, hydrogen, and carbon dioxide, and is particularly important for anaerobic decomposition. are obligatory hydrogen-producing acetogenic bacteria, acetic acid-degrading, and methane-producing They are hydrogen-oxidizing, methane-producing bacteria. This special composition requires a certain amount of biomass. Alcohol manufacturing and/or paper manufacturing? The sludge used in the treatment of wastewater is suitable as oculant sludge. I found out. This sludge preferably contains a relatively high concentration of propionic acid and The presence of reliant acid is suitable. Therefore, preferably the proportion of Cn fatty acids (n≧2) A sludge suitable for the solution is used. A particularly suitable product is the production of sugar from sugar cane. This is sludge obtained from the treatment of wastewater produced by sludge.

Anaerobic treatment leaves ammonia in the condensate and increases the chemical oxygen demand (C) of the condensate. Carbon sources are used during nitrification and subsequent denitrification because OD) cannot be completely removed. Perform an aerobic post-treatment, whereby nitrogen-containing compounds, mainly ammonia, are finally converted to nitrogen Changes to Regarding aerobic post-treatment, the method of the present invention allows the effluent generated during anaerobic treatment to It is denitrified in the denitrification unit, potash is nitrified in the nitrification unit, and the potash is nitrified in the nitrification unit. a portion of the sludge-influent water mixture is recycled to the denitrification unit. do. The sludge-influent mixture from the nitrification unit is fed into the denitrification unit. Because nitrification and denitrification occur simultaneously in the same equipment, Optimal use is made in the denitrification of carbon sources (COD) present in carbon dioxide. recirculation rate, That is, the recirculation flow rate over the flow to the nitrification unit is approximately 1° to 30°. moreover Preferably it is 15-25, for example 20. The recirculation rate depends on the composition of the effluent, especially coal. Depends on the concentration of ammonia and other nitrogen compounds on the source.

Surprisingly, denitrification and nitrification are negatively affected if this carbon source is not present in sufficient quantities. It has been found that crude condensate can be used to supplement the carbon source without oxidation. I made it clear.

Depending on the composition of the influent and crude condensate, the influent is between 1 and 20%, more preferably contains 5-20%, in practice 10-15% crude condensate.

The sludge resulting from the nitrification unit is preferably premixed with the influent water.

Therefore, the microorganisms present in the sludge are exposed to high substrate concentrations, thereby Lock formation is encouraged. The formation of this floc, the increase of microorganisms against the agglomerates is extremely useful for later separating the formed bacterial bodies (sludge) from the treated liquid in the sedimentation tank. is important.

When the anaerobic and aerobic treatments of the present invention are optimally performed, the condensate is processed into a liquid that can be drained. According to the treatment method of the present invention, 90% BOD (biochemical oxygen demand) Processes that produce 95% BOD or more, in fact 97-99% BOD The yield rate is achieved.

Below, the processes illustrated in the flow sheets of Figure 5 (anaerobic treatment) and Figure 6 (aerobic treatment) The present invention will be described in detail with reference to specific examples of devices.

Pig waste having the composition shown in Table 3 is acidified with nitric acid to a pH of about 4.

Depending on the degree of acidification, the ammonia content of the condensate is approximately 500-2000 ppm It is.

The acidified waste is mixed with water-soluble liquid paraffin, which has a boiling point of about 180°C. match. The mixture of excrement and paraffin is concentrated in a concentrator and the vapor formed is condensed. Condenses in the condenser. This heat treatment for at least 30 minutes allows the liquid to be considered a sterilizing liquid. Obtain a concentrate that can be obtained.

Regarding the cost efficiency of excrement treatment methods, it is important to extract as many valuable products from excrement as possible. It is important to separate. Idiot the selling price of these valuable products is important Of particular importance is the cost at which these products can be separated from human waste.

In all known treatment methods, solid waste is extracted from the excreta, which after drying becomes a valuable fertilizer. Directed to separating the form portions, the so-called excrement cake.

A first known treatment method involves fermentation to generate biogas. Using the so-called Proaest method, in which excrement is first fermented in a device. be. Next, what is separated from the fermented excrement is the excrement cake after drying. solids that form valuable products. As a result of fermentation, almost all organic The compound decomposes.

A second known treatment method involves the production of amino acids such as L-lysine and L-methionine. Bacteria that can use excreta as a substrate for The method described in Dutch Patent No. 8887.00803 is added to the supernatant obtained by There is. Substrates or their containing any organic or inorganic compounds that are often disturbed. As a result of the complex composition of the supernatant, amino acids in sufficiently pure form from the excreta or supernatant Recovering the acid requires economically unacceptably high costs.

A third known treatment method is the so-called Greenfield treatment method. ) (U.S. Pat. No. 3.855,079, U.S. Pat. No. 4.270.974 and 4.608120). According to this method, non-volatile oil is added to the excrement, After dehydration of the formed oil slurry by evaporation under the influence of heat, biological oil residues are removed from the condensate formed which is discharged as effluent after treatment. Living The biogas formed during physical decomposition can be used in treatment methods. “Nato Natur en Techniek, 57. See pages 894-903 (1989).

The present invention converts animal waste, which contains useful carbon, energy and nitrogen sources, into Include in your field of vision. Their source is animal excretion in relatively pure form, as a gaseous phase. Can be separated from objects. Its carbon, energy and nitrogen sources are substantially volatile This is because it is a sexual compound. That is, they contain lower fatty acids (e.g. acetate and ammoniacal). Nitrogen and carbon sources are additionally provided by microorganisms for amino acids. Particularly ideal for microbial synthesis may exist in proportions.

Other important advantages of using substrates removed from animal waste as the gas phase is that the condensate is substantially sterile and particularly clean, i.e. does not contain mineral salts. Therefore, the condensate is like an amino acid suitable for the conditions required by microorganisms for the production of organic compounds. Therefore, the present invention provides a method for synthesizing organic compounds from animal excrement, which includes the following steps: provide a way to accomplish this.

i) Concentrating animal excrement: 11) Condensing the generated vapor; 1ii) Producing organic compounds in this condensate; adding viable microorganisms; and iv) organic compounds produced by the microorganisms. The process of separating matter from condensate.

This condensate is formed by fraction condensation into a relatively ammonia-rich first condensate. (nitrogen source) and a second condensate that is relatively rich in organic compounds. .

Depending on the microorganism used, the best results can be obtained by mixing both condensates in different proportions. A suitable carbon/nitrogen ratio is obtained.

The concentration of ammonia in the condensate is reduced at a relatively high pH, generally between 5 and 7, preferably at a pH of 1. or by concentrating animal waste at a pH of 6 to 7. Can be done. However, increasing the ammonia concentration in the condensate The goal is to lower the fatty acid concentration.

Another possibility for optimally regulating the condensate is concentration of the condensate. To that The reaction volume required, the efficiency of production and the content in the condensate are The separation of organic compounds and the organic compounds formed is improved.

All preferred embodiments described above provide that this condensate is suitable for optimal production of organic compounds. This means that the conditions can be optimally adjusted to the conditions required by microorganisms.

Furthermore, special additives can be added to this condensate. potassium, phos Minerals and metals such as phate, magnesium, iron and manganese, vita i.e. biotin and thian+1n e), protein hydrolysate, etc. Eel protein sources (e.g. soya, casein or uchishodeshi) , in particular can be added. agricultural waste, molasses and whey (vhey) Additional starch sources can be added, such as.

The conditions required by microorganisms to produce organic compounds are Since the conditions are similar to those for growing the microorganisms in a separate reactor, increase the mass of the material and then transfer this biomass in another reaction vessel. It is preferable to produce an organic compound by using the organic compound. into the first reaction vessel. A growth medium of 100% is preferred for enriching the condensate. Therefore, the method according to the present invention According to one embodiment of the method, in the first reaction vessel, the condensate enriched with an additive is The biomass of the microorganism brought into contact with the microorganism and cultured in the first reaction vessel is In the second reaction vessel, it is brought into contact with the condensate which can also be used in the first reaction vessel. .

The organic compounds produced by the vine include vitamins such as B6 and B10, and L-Li. amino acids such as lysine and/or L-methionine.

Known microbial species that can produce these amino acids include genera Arthrobacter, Brevibacterium (Brev) ibacterium), Corynebacterium ium), Bacillus, Escherichia ia), Microbacterium, Microkottica Micrococcus and pseudo compounds (i.e. acetic acid and The initial concentration of ropionic acid) here reduces odor problems for 2-3 days, e.g. Particularly preferred for the conversion products are volatile organic compounds in the carrier oil used. preferably is, for example, at least 10% and even more preferably higher concentration of the desired volatiles. By sieves with smaller amounts of condensate containing volatile organic compounds 102 is then filled with pig excrement from which a large amount of waste has been removed; This was filled with the extraction mixture through conduit 103. This extraction mixture contains 40% of 5ec-butyldioctylphosphine oxide and 60% n-dodecane. Ru.

The physical compound was dehydrated by evaporation and then the oil residue was removed from the condensate. acidification It contained phosphoric acid, imbutyric acid, butyric acid and isovaleric acid. This concentrate It was used in the following examples.

When removed from the ground, it also produces lysine.

Experiment 2 The condensate (FIG. 7) is fed via conduit 101 to a neutralization device 102. Conduit 103 After adding the neutralizing agent through the mixture, the mixture is acidified to pH 7.2. Acidified concentrated The condensate is fed via conduit 104 to reactor 105, in which microorganisms is immobilized on a carrier such as activated carbon and alginate. Inside reactor 105 The fermentation of the condensate is carried out under aerobic conditions at a temperature of about 30° C. and a pH of 7.2. Reactor 1 The through flow (through-f) of 05 (ow) is such that microorganisms are substantially washed away. Avoid being swept away.

Via conduit 6, the biomass is fed from reactor 105 to separator 107, which In the vessel, microorganisms are separated and re-supplied to the reactor 105 via a conduit 108 if desired. supply. The eluent is passed through conduit 109 to the formed amino acid, in this case L-lysyl. to a unit that selectively separates the For this reason, the separation unit Amberlite IR-120, for example, is contained in the H form.

For animal waste processing methods to be cost-effective, animal waste should be removed as much as possible. It is important to separate many valuable products. Sale of these valuable products Not just the price, but especially the expense of being able to separate these products from animal waste. is also important.

In the processing methods known to date, from fertilizer to valuable fertilizer after drying. All attention has been focused on separating the solid material, the so-called animal waste cake. .

The first known processing method was the so-called Bronst process, in which animal waste was The excrement is first fermented in a fermentation mold to generate bio-gas. . The fermented animal excrement is then dried to create a valuable animal excrement cake. Separate the solids that form the product. As a result of fermentation, virtually all organic matter is degraded. be done.

The second known processing method is the so-called greenfield method (U.S. No. 38550). No. 79, US 4,270,974 and US 4,608,120). this According to the processing method, non-volatile oil is added to animal excrement to form an oil slurry. is dehydrated by evaporation under the influence of heat and then the oily residue is removed from the condensate formed. However, this can be removed as an eluate after biological treatment. formed during biological degradation The biogas produced can be used in the processing process. Furthermore, “Nature et Technique” 57, pp. 894-903 (1989).

The present invention recognizes the presence of valuable volatile organic compounds in animal waste, which It is removed from animal excreta without prior fermentation, and this condensate is subjected to appropriate physicochemical separation. When subjecting to separation methods to separate volatile organic compounds, it is possible to economically separate them from animal waste. This is based on the knowledge that it is possible to separate These compounds are, on the one hand, organic , on the other hand, they can be separated by volatility.
