High-efficient pollution-cut system with drainage pump station collecting tank dynamic division

Abstract

The invention relates to a high-efficient pollution-cut system with a drainage pump station collecting tank dynamic division. The high-efficient pollution-cut system comprises a sewage collecting tank and a rainwater collecting tank arranged adjacent to the sewage collecting tank and both having an opened top, a dynamic division device arranged between the sewage collecting tank and the rainwater collecting tank, a rainwater sewage inlet pipe communicated with the sewage collecting tank, a sewage intercepting pump disposed in the sewage collecting tank, a sewage pipe net communicated with the sewage intercepting pump, a rainwater pump disposed in the rainwater collecting tank, a drainage pipe communicated with the rainwater pump and an electrical controller electrically connected the dynamic division device, the sewage intercepting pump and the rainwater pump in respective. Compared with the prior art, the system is simply structured on the whole; sewage in draught days and primary rainwater can be intercepted in the sewage collecting tank, so sediments in the rainwater sewage cannot settle and efficiency of intercepting pollutants in the sewage in the draught days and the primary rainwater can be improved for the sewage intercepting pump; and the high-efficient pollution-cut system is suitable for reconstruction and new-construction of drawing pump stations and has great social and economic benefits.

Description

technical field [0001] The invention belongs to the technical field of rain and sewage treatment, and relates to a high-efficiency sewage interception system for dynamic partitioning of sump pools of drainage pump stations. Background technique [0002] Nowadays, with the expansion of cities and the increase of construction density, the rate of ground hardening is getting higher and higher, the original reservoirs, mountains, lakes, and fish ponds are gradually being occupied, and the sections of rivers are getting narrower and narrower. , Drainage and natural purification capabilities are greatly weakened, coupled with the urban heat island effect leading to frequent extreme weather, urban flooding and waterlogging seriously threaten the safety of life and property of urban residents, and waterlogging has become a difficult problem in urban water management. The extremely high population density and urban construction density make the urban non-point source pollution load r...

Problems solved by technology

In the combined drainage system, during sunny days, early rains and light rains, the flow of rainwater and sewage in the pipeline is small, and the designed sewage interception pump in dry weather is easy to deposit pollutants in the drainage pipeline and the sump of the drainage pumping station due to the small flow. It can effectively intercept the amount of sewage, but it is difficult to effectively intercept the corresponding pollutants or pollution loads; when the overflow in rainy days or the rainwater pump is released into the river, the sediment or pollution load accumulated in the previous period will be washed by the high-velocity rainwater and released into the river with the overflow. have a serious impact on the water quality of receiving water bodies

At the same time, due to various reasons, the rainwater pipe network of my country's separate drainage system has been mixed with different degrees of sewage, which has become a de facto combined pipe network. There is a rainy day overflow discharge river pollution similar to the confluence pumping station
