Background

China is a country with relatively lack of water resources, the water resources are not uniformly distributed in time and space, precipitation and runoff are mainly concentrated in summer due to the fact that most regions are located in subtropical monsoon climate areas, and drought disasters frequently occur in winter and spring, so that the control and utilization of rainwater are very important.

The initial rainwater is mixed with atmospheric dust and pollutants on the roof and the ground, so that the components are complex, and the pollution degree even exceeds that of urban domestic sewage by some indexes. According to the rainwater flowing through the area, the main components include tree branches and leaves, wastes, silt and a large amount of suspended matters, and if the rainwater flows through the area, the rainwater also can have other pollutants such as oil stains and the like. The current common practice is to abandon the initial rainwater with the thickness of 5-10min or 2-3mm before the rainfall before entering the rainwater recycling system.

The existing rainwater discarding device mostly adopts a small pipe discarding method or a volume discarding method. The waste stream of the small pipe is often discharged into a downstream rainwater pipe because the problem of odor or sewage backflow with a sewage system cannot be solved, so that initial rainwater does not enter the sewage system; the abandon a class start mode adopts electronic or mechanical component mostly, because the initial rainwater composition is complicated, very easily causes mechanical component because of silt or impurity jam and malfunctioning. The storage pool is adopted in the volume method, and after rainfall is finished, all rainwater in the storage pool is discharged into a sewage pipe network through a lifting pump, so that time and electricity are consumed.
