摘　　要：近年来,武汉市南湖流域排水系统运维状况不佳,基于城市发展需要,排水系统提质改造势在必行。对南湖流域排水系统运行情况进行全面摸查,发现污水稀释、沉积物淤积、危害气体逸散等问题。基于传统重力式和压力式排水系统特点对比,选取民族大道、南湖大道和中南财大区域作为先行示范,新建3个系统性压力式排水系统,对规划和建设方案进行了阐述,有望实现“点对点”传输污水,污水收集和传输效率得到显著提高。压力式排水系统中污水流速较高,能够有效减少危害气体生成,有助于沉积物强制冲刷,对于污水的稳定输送具有重要意义。此外,对南湖流域新建压力式排水系统的经济效益、环境效益和社会效益进行了评价,并分析了工程重难点及运行问题。In recent years,the operation and maintenance of the sewer system in Nanhu Lake area of Wuhan were unsatisfactory.Based on the needs of urban development,it is essential to improve the quality of the sewer system.This study clarified the issues of sewage dilution,sediment deposition,and harmful gas escape while conducting a thorough investigation of the Nanhu basin’s sewer system.According to the characteristic comparison between traditional gravity sewer systems and pressure sewer systems,the Minzu Avenue,Nanhu Avenue,and Central South University of Finance and Economics area were selected as the first demonstration of pressure sewer construction.The planning and construction schemes of the three new pressure sewer systems were elaborated.It was expected to realize“point‑topoint”sewage transmission,which might significantly improve the efficiency of sewage collection and transmission.The high flow rate of sewage in a pressure sewer system can effectively reduce the generation of harmful gases and contribute to the forced erosion of sediments,which is of great significance for the stable transport of sewage.In addition,this study also evaluated the economic,environmental,and social benefits while analyzing the key difficulties and operation problems.
