Sewage treatment plants typically employ gravity flow methods through various structures and equipment in the operational process flow. However, due to the restrictions of the terrain and the geology of the plant area, a lifting pump station must be added at the pretreatment part to lift the sewage to a certain height, and then the operation can be carried out according to the gravity flow method. The sewage lifting pump station is used for lifting the upstream sewage to the height required by the subsequent treatment unit so as to realize gravity flow. The lift pump station generally consists of a water pump, a reservoir and a pump room.

The reservoir has the function of adjusting the unbalance between the water inflow and the pumping volume, and the frequent starting of the water pump is avoided. Although the grid is arranged in front of the reservoir to intercept floating objects and the grit chamber removes most of sand, as the speed of sewage entering the reservoir is slowed down, some silt can be deposited and some scum floats on the water surface of the reservoir, so that the effective tank volume is reduced, even the water pump is blocked, and the normal operation of the water pump is directly influenced. Therefore, sundries are regularly cleaned according to specific conditions in the reservoir, and the normal operation of the water pump is guaranteed. The most important thing is the personal safety problem when the pool cleaning work is carried out in the closed water storage pool. Because the sludge and sand precipitated in the reservoir are not effectively treated and deposited in the reservoir, toxic gases such as H2S, SO2, CO and even combustible gas such as methane and the like are generated due to anaerobic decomposition. Before the pool cleaning personnel leave the pool and clean, forced ventilation is needed, whether toxic gas and combustible gas exist or not is detected at the most unfavorable point of ventilation, and after the detection meets the national standard, the respirator such as a wearable respirator and the like can work.
