采用汛期溢流格筛净化城市雨污混合溢流污水

Reduction of CSO Loadings Using Overflow Screen

城市雨污混合溢流污水(CSO)是我国水体污染的主要来源之一,混合溢流污水携带固体垃圾进入受纳水体之后造成水质恶化。削减雨污混合溢流污染是解决城市水体黑臭和湖泊富营养化治理的重要措施。借鉴欧洲国家的应用经验,通过安装混合溢流污水格筛,可以有效截留固体垃圾物质,降低COD污染程度。

Combined sewage overflow (CSO) was one of the main sources of water pollution in China, while many solid waste had caused deterioration of water quality after entry into the receiving water body. Reducing CSO pollution was an important measure to solve the problem of urban water black odor and lake eutrophication. By learning the application experiences in European countries, CSO screen was installed to effectively detain solid waste and reduce COD pollution level.
