Description

[Detailed description of the invention] [Industrial application field] This invention is installed in a part of the domestic drainage pipe of a house, etc. to remove impurities from the wastewater, purify the wastewater, and drain it into the sewer, etc. The present invention relates to a purification device for domestic wastewater, etc.

[Conventional technology]

Conventionally, wastewater from kitchens, bathrooms, etc. in homes is discharged directly into gutters, sewers, etc. through drain pipes, but this has caused the wastewater to be contaminated with scum from household garbage, detergent, and other impurities. When water is drained repeatedly over a long period of time, impurities accumulate in gutters, sewers, etc., impairing the flow of sewers, producing bad odors, and impairing the sanitary environment around houses. 2. Description of the Related Art Garbage, detergent, etc. flow out from sewers into rivers and lakes, contaminating rivers and lakes, and becoming a major cause of environmental pollution. In order to prevent this kind of environmental pollution, various measures are being taken to appeal to local residents to respect public health etiquette and to improve the cleaning management of sewers, etc., but none of them are environmentally friendly. The reality is that it is not an effective means of preventing pollution.

[Problem that the invention attempts to solve]

This invention was created in view of the above circumstances, and its purpose is to efficiently remove impurities from domestic wastewater, etc., and to exhibit excellent purification functions to eliminate environmental pollution caused by domestic wastewater. At the same time, the septic tank itself does not require expensive drainage equipment such as pumps, saving energy and reducing product costs.Furthermore, the septic tank itself has been made smaller, allowing it to be used in narrow spaces such as residential alleys and backyards. To provide a highly practical purifying device for domestic wastewater, etc., which can be easily installed without requiring space, is extremely simple to maintain and manage, and is highly practical.

[Means to solve the problem]

In order to achieve the above object, the present invention installs a septic tank in a domestic drainage pipe, and furthermore, the main body of the septic tank is composed of a plurality of sedimentation chambers that are connected in sequence, and the first sedimentation chamber side is A water pipe leading to domestic wastewater is connected, and a filtration chamber containing an activated carbon filter is provided above the final settling chamber.
The chamber is provided by being immersed in water near the water surface, and
The filtration chamber and the drain pipe outside the tank are connected through a water pipe, and the water pipe is formed so that the purified waste water inside the filtration chamber flows down into the pipe, and the drain pipe outside the tank is connected to the water level of the septic tank. This height difference allows the water in the septic tank to flow naturally to the outside.

[Effect]

The waste water flowing out from the domestic drain pipe is first led to the inflow water pipe and discharged into the water of the first settling chamber,
It flows slowly in the settling chamber while drawing a circular trajectory,
In the flow process of this wastewater, relatively heavy impurities to light impurities are precipitated and deposited, and then the wastewater flowing into the next chamber is separated by precipitation in the same manner as above and enters the final settling chamber, where the remaining impurities are almost completely precipitated. After separation, the wastewater permeates into the filter, and in this filtration chamber, fine impurities are removed, and the adsorption action of activated carbon deodorizes the wastewater, and organic solvents in the wastewater are recovered. Ru. Next, the purified wastewater collects at the inlet of the water pipe that communicates with the filtration chamber and falls into the pipe, and then is led to the drain pipe outside the septic tank through the water pipe, making use of the head of the drain pipe. and flows out from the pipe toward the outlet.

During this flow process, first, relatively heavy impurities to light impurities are precipitated and deposited in the first precipitation chamber 3. , then the second precipitation chamber 4 and the third precipitation chamber 5
The remaining impurities are almost completely separated by precipitation, and the fine particulate impurities remaining in the water are removed by the purifying action of the filter bacteria. After that, the drainage is carried out in the filtration chamber 12.
It flows into the filtration chamber through the water permeation hole 17, passes through the activated carbon filter 14, and is stored in the filtration chamber 12 up to a constant flow rate. In this process, the waste water is deodorized by the adsorption action of the activated carbon filter 14, and organic solvents are recovered, so that the waste water is further purified. Next, the wastewater purified in the filtration chamber 12 sequentially flows into the inlet 20 of the water pipe 19 drawn into the chamber 12, flows down into the water pipe, and passes through the water pipe 19 while mixing air to the outside of the septic tank 1. Flows into drain pipe B, flows out from the drain, and is discharged into gutters and sewers.

〔effect〕

As described above, according to the present invention, (1) impurities such as domestic wastewater are efficiently recovered by the settling chamber installed in the septic tank, and the wastewater is deodorized by the adsorption action of the activated carbon filter installed in the filtration chamber. Since the organic solvents are recovered, the cleaning of wastewater is further improved, and excellent purification function is exhibited, ultimately preventing pollution of rivers and lakes caused by domestic wastewater, and further improving the quality of water. According to the structure of the invention, since the filtration chamber is provided above the final settling chamber, the most supernatant purified water flows out through the filtration chamber, which further improves the purification effect described above. In this invention, the purified water in the filtration chamber flows down into the water pipe, and a head difference is provided between the drain pipe outside the tank and the water level in the septic tank, so that the purified water flows out naturally. It does not require expensive equipment such as water pumps, saves energy, and reduces the cost of this type of product.
