摘要:
随着城市点源污染问题的逐步解决，城市雨水径流污染负荷在水环境中的占比正逐步增大。城市雨水径流在形成过程中，经历大气、下垫面和管道三阶段的污染物冲刷与积累，其中前两个阶段初期冲刷效应明显，理论上源头控制设施可以获得更好的污染物控制效果。以生物滞留池、透水铺装、雨水桶作为源头体积控制的典型设施，以耦合控制模块搭建的末端截流调蓄池作为末端体积控制的典型设施，进行了不同情景的场次与多年模型模拟，并使用MV控制比对场次模拟结果进行处理。模拟结果显示，与雨水桶和调蓄池相比，具有下渗功能的生物滞留池和透水铺装的污染物控制效果更佳；对于雨水桶、调蓄池等调蓄类设施，其污染物控制效果主要由设施规模与排放规则共同决定。
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.
