Abstract

The invention discloses a first rain treatment system which comprises a first rain collecting system, a first rain storing pool, and a first rain filtering system which are communicated in sequence, wherein the first rain filtering system comprises a hydrocyclone, a rapid filter tank, and a water pump for pumping the first rain from the first rain storing pool into the cyclone separator; an underflow port of the hydrocyclone is connected to municipal sewage network pipelines, and an overflow port is connected to the rapid filter tank. Compared with the prior art, the beneficial effect of the invention is that the treatment capacity of the rainwater treatment system is improved.

Description

technical field [0001] The invention relates to a rainwater treatment system, in particular to an initial rain treatment system. Background technique [0002] China's cities have a high population concentration, high land use intensity, multiple drainage systems, large rainfall, and sufficient rainwater resources. On the one hand, they are facing flood peak flood hazards, and on the other hand, the non-point source pollution caused by rainwater runoff has aggravated urban water bodies. Deterioration of the water environment. [0003] The problem of non-point source pollution of initial rainwater in diversion system is the most prominent. In the early stage, the amount of rainfall is large, the amount of suspended matter is large, and the pollution load is high. A more economical and effective method is to treat initial rainwater through a rapid filtration system, but traditional rapid filtration tanks have problems such as easy clogging, short backwash cycles, and unstable...
