Work flow chart as shown in Figure 1, the working process of the present utility model is:

1. Pretreatment

When there are impurities such as vegetable leaves and plastic bags in the wastewater, they should be removed in advance.

2. Large water tank stage

Domestic wastewater (slightly polluted wastewater such as face washing water and vegetable washing water) enters the sedimentation area a of the large water tank 1 through the water inlet pipe 2, and after a period of precipitation, it passes through the overflow plate 8 and the filter screen 7 to the water distribution area b for storage.
