摘　　要：合流制系统改造及溢流污染控制是黑臭河道治理的核心工作之一。文中在总结国内外合流制溢流污染(CSO)治理措施的基础上,论述了巢湖市排水系统溢流污染控制策略。系统分析了合流制溢流污染产生的原因,依据巢湖市污染排查和管网检测等前期研究相关结果,提出了整体控制策略;并选取典型区域小王庄中沟,提出针对典型区域合流制系统的控制措施,即在现有管网的基础上,借助管网系统与系统之间的互调性以及末端调蓄控制手段,对整个管网的污水运行及入河排放进行污染物溢流污染控制。Reconstruction and pollution control of combined drainage system is one of the core works of black-odor river regulation.On the basis of investigating and summarizing control measures of overflow pollution(CSO)at home and abroad,pollution control strategy of overflow pollution in Chaohu City is analyzed.By abundant investigations,the causes of overflow pollution in combined drainage system are systematic analyzed.Based on the results of preliminary studies on Chaohu City’s pollution investigation and pipe network detection,some control measures areproposed.As a result,an optimal scheduling strategy is proposed for Xiaowangzhuang middle ditch,which is a typical area for CSO pollution.By virtue of the intermodulation between pipe network system and the strategy of terminal regulation and storage control,the optimal control of sewage operation and discharge into the river is carried out for the whole pipe network.
