摘　　要：我国许多城市长期面临着污水厂进水浓度低、管网存在混接缺陷等复杂的水环境问题,而污水系统提质增效是解决这一挑战的重要举措。芜湖市作为长江大保护的首批试点城市,其污水提质增效工作成效显著。针对该市某片区排水系统存在的管网缺陷、混接,污水厂进水量不足、进水浓度低等问题,基于系统分析的方法对污水系统进行分析诊断,并开展了系统排查、管网评估与修复等一系列工作,取得了较明显的效果。片区污水处理厂进水量由1×10^(4) m^(3)/d增至4.2×10^(4) m^(3)/d,进水COD浓度由80 mg/L增至近130 mg/L。分析总结该项目的系统性理念与实践经验,有助于为后续长江大保护及其他城市的污水系统提质增效与水环境整治工作提供参考。Many cities in China have been faced with complex water environment problems such as low influent concentration of wastewater treatment plant(WWTP)as well as mixed connection and defects of drainage pipe network.Improving the quality and efficiency of sewage systems is an important measure to solve this challenge.As the first pilot city of Yangtze River protection,Wuhu has achieved remarkable results improving the quality and efficiency of sewage system.In view of the problems in the drainage system of a certain city area,such as mixed connection and defects of the pipe network,insufficient and low‑concentration of influent in the WWTP,the sewage system was analyzed and diagnosed based on system analysis method.A series of work such as system investigation,pipe network assessment and repair were carried out,and obvious results were achieved.The influent volume of WWTP increased from 10000 m^(3)/d to 42000 m^(3)/d,and the influent COD concentration increased from 80 mg/L to 130 mg/L.The systematic concept and practical experience of the project are analyzed and summarized,which is helpful to provide reference for the subsequent Yangtze River protection and other cities’sewage system improvement and water environment improvement work.
