Description

TECHNICAL FIELD The present invention relates to a wastewater treatment apparatus suitable for treating small-scale wastewater such as in general households. More specifically, it relates to improvement of facility of such a wastewater treatment device.

[Conventional technology]

Currently, the need to save water is emphasized, mainly in urban areas,
Even in ordinary households, bath water is reused as washing water and sprinkling water. On the other hand, the sewage treatment capacity in urban areas has not reached the level of treating all wastewater, and the amount of wastewater that flows into rivers is considerable, contributing to environmental pollution. And as for this outflow drainage, the drainage of general households is increasing instead of the reduction of industrial drainage due to the regulation.

Conventionally, under such circumstances, various types of wastewater treatment devices have been provided for storing and treating bath water and washing and rinsing water for reuse as flush toilet water and sprinkling water, for example, a type to be buried in a garden. ， The type of installation on the roof is known.

[Problems to be solved by the invention]

With the above-mentioned conventional technology, it is impossible to install in a residential-type condominium that is popular in urban areas, and
Even in a single-family house, there is a problem that the construction cost must be increased because the piping work must be installed on the garden or the roof.

[Object of the Invention]

The present invention has been made in view of such problems,
The purpose is to make it possible to install at low cost regardless of the type of house and to improve the facility of the wastewater treatment equipment.

[Means for solving problems]

The wastewater treatment apparatus according to the present invention has an outer shape that can be installed in a narrow space such as the inside of a partition wall of a house, and at least a raw water pump that takes in wastewater and a treated water pump that takes out treated water and a wastewater treatment system. It is provided with a plurality of compartments.

[Operation of the invention]

The wastewater treatment device according to the present invention is a device that is installed in a house to shorten the piping line and effectively use a dead space such as the inside of a partition wall so as not to become an obstacle in daily life. In addition, by further providing a raw water pump, a treated water pump, and a plurality of compartments, smooth distribution of the drainage reuse route between intake of wastewater and treatment and removal of treated water is achieved.

Example of Invention

An embodiment of a wastewater treatment device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment in which a partition wall is installed inside a house. The partition wall 3 is provided between the ceiling 1 and the floor 2.
The entire thin box-shaped tank body 4 is housed inside. Partition wall 3
Since there is usually a gap 5 of about 10 cm in the interior of a single-family house or a condominium, this gap 5 is used for installation. The gap 5 may be filled with a fireproof material or the like. In this case, even if the fireproof material or the like is removed, the fireproof performance is deteriorated by making the tank body 4 a fireproof material or the like. There is no such thing.

In addition, this equipment is not a problem when building a new house, but when installing it in an existing house, it is sufficient to carry out some modification work. That is, since the partition wall 3 has a structure in which the wall material 32 is normally fixed to the crosspiece 31, if the wall material 32 and the crosspiece 31 are cut, the tank body 4 can be easily stored in the gap 5. In addition,
If the cut wall material 32 and the crosspiece 31 are detachably attached to the tank body 4, the ceiling 1 or the floor 2, there is an advantage that maintenance management can be easily performed.

In addition to the embodiment provided inside the partition wall 3 described above, the service pit of the condominium may be used, for example.

FIG. 2 shows an example of the internal structure of the tank body 4.
Is a machine room divided into three compartments 41, 42, 43 and its lower part
44, and the machine room 44 is provided with a raw water pump 6 for taking waste water into the tank body 4 and a treated water pump 7 for taking out treated water from the tank body 4. The compartment
The first compartment 41 of 41, 42, 43 is a raw water tank for storing the waste water taken in from the raw water pump 6, and the second compartment 42 is a treatment tank that includes a partition plate 45 and an aerator 8. The drainage corresponding to these treatment capacities is fed from the first compartment 41 via the flow rate adjusting pump 9, and the third compartment 43 overflows from the second compartment 42 in the treated water tank. The treated water is stored and the treated water is taken out by the treated water pump 7 at a proper time. The compartments 41, 42, 43 are vent pipes 46, 47.
An exhaust pipe 48 is provided in the third compartment 43, and an overblow pipe 49 is provided in the first compartment 41 and the third compartment 43.

The inlet pipe 6 ′ connected to the raw water pump 6 is designed to allow bath water, laundry rinse water, etc. to flow in, and such drainage can be purified by calming at least a plurality of compartments. In the illustrated embodiment, the purification treatment capacity is enhanced by the precipitation by the partition plate 45 and the aeration by the aeration device 8 to prevent foaming during use of treated water, corrosion in each pipe portion, and pigmentation. Note that other biological treatment means or physicochemical treatment means may be added.

The outlet pipe 7'connected to the treated water pump 7 is
It supplies treated water to water tanks, sprinkling cocks, etc. of flush toilets, and supplies and operates according to demand for these.

FIG. 3 illustrates the storage capacity of the tank body 4. For example, the width W is 160 cm (60 cm for the first compartment 41, 40 cm for the second compartment 42,
If the third compartment 43 is 60 cm, the height H is regulated by the ceiling 1 and the floor 2, but it can be about 220 cm (however,
The effective water depth of the first compartment 41 is 170 cm, the effective depth of the second compartment 42 is 170 cm, the effective depth of the third compartment 43 is 150 cm, and the depth D is 10 cm as described above. Ability is calculated.

First compartment 60 (W) x 10 (D) x 170 (H) x 1/1000 = 102l Second compartment 40 (W) x 10 (D) x 170 (H) x 1/1000 = 68l Third Compartment 60 (W) x 10 (D) x 150 (H) x 1/1000 = 90l 102 + 68 + 90 = 260l Therefore, a large amount of water in the flush toilet, which is used intermittently little by little during the day It also has sufficient storage capacity for discharged bath water and washing rinse water.

〔The invention's effect〕

INDUSTRIAL APPLICABILITY As described above, the wastewater treatment device according to the present invention can be installed in the house so that the piping line can be shortened and the facility cost can be reduced, and the facility can be installed by using the dead space such as the inside of the partition wall Therefore, it has the effect of not becoming an obstacle in daily life.

In addition to the improved facility, the wastewater is purified and reused effectively, saving water, preventing drainage from flowing into rivers, and contributing to improving the living environment in urban areas. There is.
