Abstract

PROBLEM TO BE SOLVED: To prevent clogging of a piping by shortening the piping to communication tanks to each other and to miniaturize an overall device by making treated water made by cleaning livelihood drain in a water catchment tank as toilet wash water and burying a reclaimed water treatment system underground free to reuse it. SOLUTION: Livelihood drain reserved in a drain catchment tank 3 is purified and treated by a biological purifying film treatment, etc., by flowing it in a cleaner 1 through a pump 4, and treated water is reserved in an adjacent treated water reservoir tank 2. Thereafter, a pump 6 arranged in this reservoir tank 2 is actuated, treated water is supplied to a toilet in a dwelling houses and reused as wash water. Thereafter, a clear-water piping is erected on a ground part from underground and piped in the housing. In this case, each of the tanks 1, 2, 3 is buried underground, and the ground part is efficiently used by arranging a passage, etc., on it. Additionally, an overall device is miniaturized by designing the piping to connect each of the tanks 1, 2, 3 short, and occurrence of clogging in the inside of the piping is minimized. Consequently, it is possible to reduce cost of contruction work and to easily carry out construction.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a residential sewage treatment system.

[0002]

2. Description of the Related Art The inventors of the present invention have already filed an application for a sewage treatment system as schematically shown in FIG. 2 as a sewage treatment system for a house. , Wastewater discharged from a bathroom, a washing surface, etc., and domestic wastewater such as rainwater are temporarily stored in a drainage catchment basin 3, and a pump 4 provided in the drainage catchment basin 3 is operated to pressurize a pressure feed pipe 5 Through which the domestic wastewater flows into the purification device 1,
A biological purification treatment is performed in the purification device 1 to purify domestic wastewater, and the treated water is stored in a treated water storage tank 2 provided at a lower portion, and sequentially circulated through the purification device 1 and the treated water storage tank 2 to reduce the size. The wastewater is treated by the above device, and the wastewater is treated by a pump 6 through a water purification pipe 7 to a toilet bowl in a home, and can be reused as toilet flush water.

In such an intermediate water treatment system,
From the viewpoint of maintainability and workability, the purification device 1 and the treated water storage tank 2 are installed above the ground, and the piping such as the pressure feeding pipe 5 or the pipe connecting between the tanks and the water purification pipe 7 are long and complicated. Therefore, there is a problem that it is difficult to reduce the size. Further, since the pipe is long and complicated, there is a problem that clogging in the pipe, decay of domestic wastewater in the pipe, and generation of offensive odor easily occur.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised in view of the above-mentioned conventional problems, and makes it possible to reduce the size of the entire apparatus and to prevent clogging of pipes and rot in pipes. The first gist of the present invention is to provide a residential sewage treatment system that purifies domestic wastewater collected in a catchment basin by a purification device and treats the treated water stored in a treated water storage tank to a toilet. In a residential sewage treatment system configured to be reusable as wash water or the like, the water collecting basin, the purification device, and the treated water storage tank other than the control unit constituting the system are buried underground. Also, the second gist is:
The water collecting basin, the purification device, and the treated water storage tank are provided integrally or in proximity to each other.

[0005]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an intermediate water treatment system of the present invention, in which all parts other than a control unit (not shown) constituting the intermediate water treatment system are buried underground, and a drainage water collecting reservoir 3 and a purification device 1 and the treated water storage tank 2 are integrated,
In addition, they are buried underground in a state of being extremely close to each other, and domestic wastewater generated in the house is introduced into the drainage catchment 3 and is stored therein. The domestic wastewater stored in the inside flows into the purification device 1 via the pump 4 and is purified by a biological purification membrane treatment or the like in the purification device 1, and the treated water after purification is stored in an adjacent treated water storage tank. 2 is operated by a pump 6 provided in the treated water storage tank 2 to supply water to a toilet at home through a purified water pipe 7 so that it can be reused as toilet flush water at home. Water purification pipe 7
Is erected from the basement to the ground, and piped into the house. The drainage catchment tank 3, the purification device 1, and the treated water storage tank 2 are all buried underground. It is possible to form a passage or the like for effective use, and the apparatus can be extremely compactly installed in a buried state, and furthermore, each of the drainage catchment tank 3, the purification device 1, and the treated water storage tank 2 Can be designed to be extremely short, and the piping can be made extremely compact without the need for complicated and long piping as in the past. Can be done. In addition, since the piping is shortened, clogging in the piping is reduced, and stagnation of domestic wastewater due to stagnation in the piping is reduced, and generation of offensive odor can be reduced.

[0006] Furthermore, it may be configured such that the domestic wastewater flows into the purification device 1 by overflowing from the drainage collecting reservoir 3, or the treated water is overflowed from the purification device 1 to the treated water storage tank 2. May be made to flow, and if it is a type that overflows like this,
Piping can be omitted, and it can be made more compact. In addition, the drainage catchment tank 3, the purification device 1, and the treated water storage tank 2 are connected by overflow type gutters, respectively, and overflow the wastewater from the drainage catchment reservoir 3 to the purification device 1, and from the purification device 1 to treated water. It is also possible to provide a structure that allows water to flow into the storage tank 2, and it is possible to omit piping between the tanks to make an extremely compact device. It is preferable that the control unit, the pump, the air pump, and the like be installed on the ground from the viewpoint of maintenance.

[0007]

According to the present invention, domestic wastewater collected in a water collecting tank is purified by a purifier, and the treated water stored in a treated water storage tank can be reused as toilet cleaning water or the like. In the residential sewage treatment system, the water collecting basin, the purification device, and the treated water storage tank other than the control unit constituting the system are buried underground, so that the entire apparatus is converted into a compact and the tanks are connected. The piping can be designed short and installed easily, and the piping is shortened, so that clogging in the piping and decay of domestic wastewater in the piping can be prevented well,
In addition, there is an effect that the ground side can be used effectively.

In addition, the water collecting basin, the purification device, and the treated water storage tank are arranged integrally or in proximity to each other,
By making them integral or close to each other, the piping between the tanks can be made extremely short, and the entire device can be set to an extremely compact size, making installation easy, and because the piping is short, clogging in the piping In addition, the spoilage of domestic wastewater is extremely reduced, and the effect of successfully preventing the generation of offensive odor is obtained.
