雨水管网水质过程线模拟研究

Research on the Simulation of Quality in Rainwater Pipe Networks

以雨水中污染物质的浓度为研究对象,采用一阶负荷模型与阶式CSTR模型,对雨水地表径流过程与管网中的传输过程进行模拟,得出了雨水管网进出口污染物质的浓度变化过程线,并通过实例工程进行验证。模拟结果表明,该模拟方法结果稳定,得出的雨水管网水质过程线可以用于研究雨水造成的污染情况,并对雨水受纳水体的修复提供理论数据。

Using first-order load model and Tile-CSTR model,this paper simulates rainfall runoff process and the transmission process in pipeline networks for the study of pollutants concentration in rainwater.The simulation study obtains the change process line of pollutants concentration in rainwater pipe networks.This process line is verified by actual project.The results show that this simulation has stable results;its process line can be used to study the pollution caused by rain.Finally,these results can provide theoretical data for the restoration of rain-receiving water.
