为研究市政泵站雨天排放对受纳水体水质的影响程度，利用一维河网水量水质模型和管网模型进行耦合计算，分析黄浦江、苏州河沿线73座市政泵站在不同典型降雨时段溢流排放时，对黄浦江和苏州河的水质影响程度进行了定量化研究。结果表明：雨天市政泵站排放对黄浦江和苏州河的水质浓度有不同程度的影响，越靠近中心城区的河道水体污染物浓度升幅越大，降雨量越大对水体的水质影响也越大；要降低市政泵站雨天排放对黄浦江、苏州河水质的影响，需采取工程措施和非工程措施综合措施来进行治理。

In order to analyze the influence of overflow discharge from municipal pumping stations in rainy days on the water quality of the receiving water bodies , the overflow discharge during typical rainfall periods from 73 municipal pumping stations along the Huangpu River and Suzhou Creek were studied .Through coupling of a one-dimensional hydrodynamic and quality river network model and a pipe network model , the influence on the water quality of the Huangpu River and Suzhou Creek was quantitatively studied .The results show that the discharge from the municipal pumping stations in rainy days had different influences on pollutant concentrations in the Huangpu River and Suzhou Creek:the nearer to the city center , the higher the pollutant concentrations were , and the greater the rainfall , the greater the influence on the water quality became .In order to reduce these influences , engineering measures and non-engineering measures should be taken in an integrated manner .
