国内外对合流制管道溢流污染的控制与管理

Control and Management of Combined Sewer Overflow Pollution at Home and Abroad

随着城市化进程的加快,城市雨水问题以及合流制排水管道的溢流污染问题变得日益严重。合流制管道的溢流污染已成为部分城市改善水体水质的主要制约因素之一。若未经有效处理的溢流污水直接排入水体中,不仅会严重地破坏水环境功能,还将危及人类健康。介绍了国内外部分城市控制合流制管道溢流污染的概况,分析了我国目前控制合流制管道溢流污染存在的问题和不足,讨论国外经验对我国的启示并提出一些建议,为我国对合流制管道的溢流污染控制提供借鉴。

With the rapid development of urbanization, the problems of urban stormwater and combined sewer overflow （CSO） pollution become increasingly serious. CSO pollution has become one of the main factors affecting receiving water quality in some cities. If the untreated overflow sewage flows directly into the receiving water, it will destroy the function of the water environment and endanger human health. The general situation on the CSO pollution control at home and abroad is reviewed. The problems and gaps in the CSO pollution control in China are analyzed. The inspiration from foreign experience to China is discussed, and some suggestions are put forward to provide reference for the CSO pollution control in Chinese cities.
