The utility model aims to overcome the defects in the prior art, and provides the sewage treatment separation and purification box which is simple in structure, convenient to use and install, smaller in occupied area compared with a conventional treatment device, simple to operate and good in treatment effect. The utility model aims to solve the technical scheme that the simple domestic sewage treatment box comprises a box body, wherein a water inlet is formed above the box body, a water outlet is formed in the bottom of the box body, a large-particle treatment layer, an anaerobic layer, an aerobic layer and a water storage layer are sequentially arranged in the box body from top to bottom, multiple layers of filter screens are arranged in the large-particle treatment layer, gaps among the filter screens are gradually decreased from top to bottom, water drainage holes are formed in two side edges of each filter screen, a partition plate is arranged in the anaerobic layer to divide the anaerobic layer into a left chamber and a right chamber which can independently perform water treatment, the bottom of each chamber is connected with the aerobic layer at the bottom through a pipeline with a valve, a plurality of aeration pipes are arranged in the aerobic layer, the bottom of each aeration pipe and the water storage layer are communicated through a pipeline with a valve arranged on the outer side wall of the box body, and two backflow pipelines connected with the anaerobic layer are further arranged on the outer side wall of the box body, the return pipeline lifts water to the anaerobic layer through a lifting pump for storage.

Preferably, the method comprises the following steps: the lower water hole is provided with a switch which protrudes to the outer side of the box body and is transversely arranged, when the switch is bent downwards in an inclined mode, the lower water hole is opened, water can be reserved below the switch, when the switch is transversely arranged, the lower water hole is closed, and the water is kept in the large particle treatment layer.

Preferably, the method comprises the following steps: many aeration pipes are even arrange on the inside wall of box to be equipped with many and aeration pipe vertically aeration branch pipes on the aeration pipe, all be equipped with the aeration head on every aeration branch pipe, oxygen in the aeration pipe is supported through supporting the machine, should support the machine and place on the support that the relative box lateral wall of aeration pipe set up.

The utility model has simple structure, convenient use and installation, small occupied area compared with the conventional treatment device, wide application range, convenient maintenance and the like, the bottom of the device is full of water and then flows back to the chambers through the return pipeline to store the full water, the two chambers can work singly or together according to the amount of the treated sewage, and the device can better save resources and has flexible and efficient treatment.

Detailed Description

The utility model will be described in detail below with reference to the following figures: as shown in figure 1, a simple domestic sewage treatment box comprises a box body 1, a water inlet 2 is arranged above the box body 1, a water outlet 3 is arranged at the bottom of the box body, a large particle treatment layer 4, an anaerobic layer 5, an aerobic layer 6 and a water storage layer 7 are sequentially arranged in the box body 1 from top to bottom, multiple layers of filter screens 8 are arranged in the large particle treatment layer 4, gaps between every layer of filter screen 8 gradually decrease from top to bottom, a water outlet 9 is formed in two side edges, a partition board 10 is arranged in the anaerobic layer 5, the anaerobic layer 5 is divided into a left chamber 11 and a right chamber 11 which can independently perform water treatment, the bottom of each chamber 11 is connected with the aerobic layer 6 at the bottom through a pipeline 13 with a valve 12, a plurality of aeration pipes 14 are arranged in the aerobic layer 6, the bottom of the anaerobic layer and the water storage layer 7 circulate through a pipeline with a valve arranged on the outer side wall of the box body 1, and two backflow pipelines connected with the anaerobic layer 6 are further arranged on the outer side wall of the water storage layer 7 outside the box body 1 15, the return line 15 lifts the water by means of a lift pump 16 into the anaerobic layer 5 for storage.

The lower water hole 9 is provided with a switch 17 which protrudes to the outside of the box body 1 and is transversely arranged, when the switch is bent obliquely downwards, the lower water hole 9 is opened to leave water below, and when the switch 17 is transversely arranged, the lower water hole 9 is closed, and the water is kept in the large particle treatment layer 4.

The aeration pipes 14 are uniformly arranged on the inner side wall of the box body 1, a plurality of aeration branch pipes 18 perpendicular to the aeration pipes 14 are arranged on the aeration pipes 14, each aeration branch pipe 18 is provided with an aeration head 19, oxygen in the aeration pipes 14 is supplied by a supply machine 20, and the supply machine 20 is placed on a support 21 of the aeration pipes 14, which is arranged relative to the outer side wall of the box body 1.

When the bottom of the tank body 1 is full of water, the water flows back to the chambers through the return pipe 14 to store the full water, and the two chambers can work independently or together according to the amount of the treated sewage, so that resources can be saved better, and the treatment is more flexible and efficient.
