Abstract

PROBLEM TO BE SOLVED: To prevent an excessive load of sewerage caused by the contamination of sewage by the direct inflow of drainage containing crushed garbage by using a combined purification tank which is discarded associated with the preparation of sewerage as an apparatus for treating kitchen drainage containing garbage crushed by a crusher. SOLUTION: A combined purification tank is used as a purification apparatus 12 for kitchen drainage containing garbage crushed by a garbage crusher installed on a sink, and the kitchen drainage, after being purified by the purification apparatus 12, is discharged into sewage 14, and other living drainage from a bath, a washroom, and a toilet is discharged directly into sewage without passing through the purification apparatus 12.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wastewater treatment system, and more particularly to a wastewater treatment system including kitchen wastewater containing crushed material by a crusher for garbage disposed on a sink.

[0002]

2. Description of the Related Art
BACKGROUND ART There is known a crushing device for kitchen trash that is attached to a lower part of a sink in a kitchen sink and crushes kitchen garbage that has been put in through a sink drainage port and then discharges the crushed garbage.

When a kitchen is equipped with such an apparatus for crushing garbage, the garbage can be treated simply by putting the garbage into the crushing apparatus through the drainage port of the sink, and the garbage is accumulated and stored. You can put it in a plastic bag and carry it to a designated place on a specified collection day, eliminating the hassle of
The convenience of daily life is significantly improved.

By the way, in collective housing such as apartments and condominiums in the undeveloped area of public sewer, a combined septic tank is generally installed, and the whole domestic wastewater from each household flows into the combined septic tank and is purified there. After being released, it is usually released.

In this case, when the kitchen wastewater containing the crushed material by the above-mentioned raw garbage crushing device is allowed to flow into the combined septic tank as it is, the conventional combined septic tank is not designed for such a case. However, the load on the combined septic tank becomes too large, which causes a problem that sufficient treatment cannot be performed.

On the other hand, even if a sewerage facility is developed in the future, if the kitchen wastewater containing the crushed raw garbage is discharged into the sewerage together with other domestic wastewater, an excessive load is placed on the final treatment plant of the sewerage facility. This causes a problem. Therefore, at present, there is a demand for refraining from using such an apparatus for crushing raw garbage.

[0007]

The invention of the present application has been made to solve such a problem. Thus, the gist of the invention of the present application is to provide a purifying device for purifying kitchen wastewater containing crushed substances by the garbage crushing device provided in the sink, and after the kitchen drainage is purified by the purifying device, sewer Meanwhile, other domestic wastewater from baths, washrooms, toilets, etc. is discharged directly into the sewer without going through the purification device.

[0008]

As described above, according to the present invention, kitchen wastewater containing crushed substances by the garbage crushing device is purified by the purifying device and then discharged into the sewer, while it is discharged from the bath, washroom, toilet, etc. The other domestic wastewater is discharged to the sewer as it is. According to the present invention, the kitchen wastewater containing the crushed raw garbage can be sufficiently purified before being discharged to the sewer. It is possible to prevent the facility from being overloaded.

On the other hand, for the purifying device, a bath,
Since the domestic wastewater from the washroom, toilet, etc. does not flow in, it does not impose an excessive load on the purifier, and the kitchen wastewater can be discharged after being sufficiently cleaned.

In the present invention, it is preferable to use an existing combined septic tank as the purifying device. If sewerage facilities are installed in apartments, the combined septic tank will be unnecessary and will be disposed of as wastewater is installed.

In such a case, by using the combined septic tank as the above-mentioned purifying device, it is possible to omit the special provision of a purifying device dedicated to purifying kitchen wastewater containing crushed raw garbage, and the purifying device can be omitted. The cost for installation can be omitted, and the cost can be reduced.

In the present invention, a single septic tank generally provided in a detached house can be reused as a device for purifying kitchen wastewater containing the above-mentioned crushed raw garbage together with the construction of sewer facilities. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, embodiments of the present invention will be described in detail with reference to the drawings. In FIG. 1, reference numeral 10 is a garbage crushing device (disposer) provided under a sink of a kitchen sink.
Then, in the case of the wastewater treatment system of this example, the kitchen wastewater containing the crushed material by the crushing apparatus 10 for this garbage is the purification apparatus 12
Is discharged to the sewage 14 after being purified there.

Here, the purifying device 12 is composed of a combined purifying tank, and the purifying device 12 composed of the combined purifying tank is used as a purifying device for general domestic wastewater before the sewage 14 is maintained. That is, in this example, the place where the existing combined septic tank should be disposed of along with the maintenance of the sewage 14 is reused as the purifying device 12 for purifying the kitchen drainage. In this example, the bath,
Other domestic wastewater from the washroom, toilet, etc. is discharged to the sewer 14 as it is.

As described above, in this embodiment, the kitchen wastewater containing the crushed material by the garbage crushing apparatus 10 is purified by the purifying apparatus 12 and then discharged into the sewage 14, while the bath, the washroom,
As for other domestic wastewater from the toilet, etc., it is designed to be discharged to the sewer 14 as it is. According to this example,
Kitchen wastewater containing crushed raw garbage can be sufficiently purified before being discharged to the sewage 14, and an excessive load on the sewerage facility can be prevented. On the other hand, since the domestic wastewater from the bath, washroom, toilet, etc. does not flow into the purification device 12, an excessive load is not applied to the purification device 12, and the kitchen drainage is sufficiently cleaned. Can be discharged to the sewage 14.

In this example, the combined septic tank that is disposed of as waste water 14 is reused as the purifying device 12, and according to the present invention, for purifying kitchen wastewater containing crushed garbage. It is possible to omit the special provision of the dedicated purifying device, and the cost for installing the purifying device can be omitted.

The embodiment of the present invention has been described in detail above, but this is merely an example. For example, in the present invention, an existing single septic tank in a detached house can be reused as a purifier for kitchen wastewater containing crushed raw garbage in accordance with the maintenance of a sewage facility. Can be configured in a form in which various changes are made without departing from the spirit of the invention.
