Background
In the urbanization process of China, the urban water environment faces many problems in recent years.
On one hand, the building area of a city is continuously enlarged, the area of a waterproof ground is increased, underground water is greatly reduced, and most rainwater is collected into surface runoff and needs to be discharged into rivers and lakes through pipelines. After rainfall falls to the roof of a building, the rainfall flows along the roof and is collected to a rainwater collecting port, enters an underground rainwater pipeline through a rainwater falling pipe on the edge of the building, and then is discharged into a municipal drainage pipe network. In cities, the area of the roof accounts for about 30%, and rainwater runoff formed after roof rainwater is converged with ground rainwater and road rainwater increases the drainage pressure of municipal pipe networks.
On the other hand, in the early stage of rainfall, a large amount of polluting gaseous substances such as acidic gases, plant exhaust gases, automobile exhaust gases and the like in the air are dissolved in rainwater. Building roofing pollutant is mainly for the deposit in roofing material decomposition thing and the atmosphere, because roofing runoff rainwater can demonstrate the initial stage scouring effect, and initial stage runoff rainwater pollutant concentration is higher, and quality of water turbidity is big because surface runoff, and municipal pipe network drainage pressure is big, and most municipal pipe networks are easy with these initial rain inflow river courses in, produce the pollution to the river course.
In order to solve the above problems, people are always seeking an ideal technical solution.
