- Abstract:
- With the gradual solution of urban point source pollution, the proportion of urban stormwater runoff pollution load in water environment is gradually increasing. In the formation of urban stormwater runoff, there are three stages of pollutant erosion and accumulation: atmosphere, underlying surface and pipeline. The first flush effect is obvious in the first two stages. Theoretically, source control facilities can obtain better pollutant control performance. Therefore, biological retention ponds, permeable pavements, rain barrels were used as typical facilities for source volume control, and the terminal interception and storage tank built with coupling control modules was used as typical facilities for terminal volume control. Various scenarios and multi-year model simulation were carried out, and the simulation results were processed by the MV control ratio. The simulation results showed that the biological retention pond with infiltration function and the permeable pavement had better pollutants control performance than that of the rain barrel and storage tank. For storage facilities such as rain barrel and storage tank, the pollutants control performance was mainly determined by the facility scale and discharge rules.
