Background

Rain and sewage flow is a drainage system, which is a sewage discharge mode that rainwater and sewage are separated and are respectively conveyed by a pipeline for discharge or subsequent treatment. The rainwater can directly arrange the river course through rainwater pipe network, and sewage need be collected the back through sewage pipe network, send sewage treatment plant to handle, and quality of water is arranged in the river course again after reaching corresponding country or local standard, can prevent like this that the river course is polluted. The rainwater and sewage diversion facilitates rainwater collection and utilization and centralized management and discharge, reduces the impact of water amount on the sewage treatment plant, and ensures the treatment efficiency of the sewage treatment plant.

However, there are also heavily polluted parts in the rain water, such as initial rain water, which is the rain water in the early stage of rainfall. Generally, the surface runoff precipitation is formed when the ground is 10-15mm thick. In the early stage of rainfall, a large amount of acid gases, automobile exhaust, factory waste gas and other pollutant gases in the air are dissolved in the rainwater, and after the rainwater falls to the ground, the rainwater in the early stage contains a large amount of pollutants due to scouring of roofs, asphalt concrete roads and the like, so that the pollution degree of the rainwater in the early stage is higher and even exceeds that of common urban sewage. The sewage is directly discharged into a river channel through a rainwater pipe, and the water supply environment is polluted to a certain degree. Because the concentration of initial rainwater pollutants is high, the condition can be set to collect the initial rainwater and discharge the initial rainwater into a sewage pipe network to be treated together with sewage.

However, the initial rainwater and the later rainwater are often not well distinguished, a large amount of later rainwater and the initial rainwater easily enter a sewage pipe network together, the pressure of sewage treatment is increased, and a large amount of clean later rainwater is wasted.
