摘要
对北京市老城区合流制管网排除系统下游干管进行降雨径流监测,分析降雨径流和生活污水混合后的水质变化特征,以便为合流制管网污染控制提供数据依据。结果表明北京市合流制管网污染程度较高,其污染过程受降雨过程、管道汇流过程、地表径流污染特征和管道沉积物冲刷等综合影响。
Monitoring the rainfall runoff in the downstream trunk of combined sewer network in Beijing old district was selected to analyze the variation of the water quality which blended the runoff and the sanitary sewage,providing data for controlling the pollution in combined sewer network.The results showed that the pollution has got a high degree in Beijing＇s combined sewer network.The rainfall intensity,collection process in sewers,pollution characteristics of the surface runoff and the wash-off processes of the in-sewer pollution stocks can affect the non-point source pollution process in combined sewer network.
