Background technique

With the acceleration of industrialization and urbanization of human society, impermeable surfaces such as roads, bridges, and buildings in cities continue to increase, precipitation runoff seepage decreases, and runoff increases sharply, which changes the natural circulation of water. At the same time, due to the increase of human activities, the types and amounts of pollutants also increase. These pollutants accumulate continuously. When there is rainfall, a large amount of pollutants on roofs and roads will be washed by the rainwater runoff and directly enter the surrounding rivers and lakes with the runoff through urban drainage pipes or floods, forming a typical urban rainfall runoff. Pollution has a shocking impact on the urban ecological environment and seriously restricts the improvement of urban water environment quality.

At present, most cities at home and abroad have problems such as serious initial rainwater pollution and low drainage capacity. Pollutants in the initial rainwater in my country contain a certain amount of organic matter, pathogens, heavy metals, grease, suspended solids and other pollutants. The main sources are particles such as smoke, dust, and toxic substances in the dry and wet deposition of the atmosphere and the underlying cushions in surface runoff. Surface natural sediment and solid waste, etc. If the initial rainwater is directly discharged into rivers or natural receiving water bodies, it will cause very serious pollution to the water body, and the initial rainwater must be collected and treated. Relevant studies have shown that, as a typical characteristic pollutant in incipient rainwater, the concentration of suspended solids (SS) has a great influence on the concentration of other dissolved pollutants. Therefore, at present, the effective treatment method to reduce the main pollutants of initial rainwater is sedimentation method, and most of the treatment structures used are grit chambers.
