摘要
通过对合流制溢流(CSOs)的形成和水质进行分析,阐明控制CSOs是解决城市水环境黑臭问题的重要途径,并梳理了控制CSOs的技术措施。治理城区CSOs可分为源头治理、过程治理和末端治理。源头治理包括雨污分流和海绵工程措施如雨水花园、雨水塘、下沉式绿地、植草沟和绿色屋顶等,可削减CSOs排放量及其有机物、氮、磷含量:过程治理是通过对老旧排水系统进行改造或清淤实现CSOs水量的减少和水质的提高;末端治理则是通过建造调蓄池以及CSOs净化设施等减少对水体的污染。
By analyzing the formation and water quality of combined sewage overflows(CSOs),it is pointed out that CSOs control is an important measure to control black and odorous water in cities.The technical measures to control CSOs are sorted out.The measures of controlling CSOs are divided into source treatment,process control and end treatment.Source control can reduce CSOs emissions and organic matter,nitrogen,phosphorus content.It includes rain and sewage diversion and sponge engineering measures such as rain garden,stormwater ponds,Sunken Greenbelt,grass swale and green roof etc.Process control is to reduce the water of CSOs and improve the quality of water by reforming the old drainage system or desilting the pipe.The end treatment is to reduce water pollution through the construction of storage tanks and CSOs purification facilities.
