摘　　要：针对珠三角某城市片区污水管网高水位、低浓度运行的现状,通过管网排查、排水监测、GIS管控平台"三位一体"的综合手段,分析诊断污水直排口419处,雨污混接点287处,支管与主管未拉通3处,河水入侵9处,地下水入侵43处。提出"清、拉、分/截、调、疏、修"技术措施,污水主管运行水位降低4 m,污水收集率提升29.5%,进厂COD平均浓度提高10 mg/L,实现污水管网提质增效,可为其他城市污水管网提质增效提供参考。Currently,the sewage network was running with high water-level and low concentration in the pearl river delta area,this study analyzed and diagnosed 419 direct sewage outlets,287 rain and sewage mixing points,3 unconnected branch and main pipes,9 and 43 invasion river and groundwater,using integrated approach of network investigation,drainage monitoring and GIS platform.The technical measures of cleaning,pulling,separating/cutting,adjusting,dredging and repairing were proposed,which could reduce the operating water level of the pipeline by 4 meters,improve the sewage collection rate by 29.5%and improve the average concentration of the water quality into the plant by 10 mg/L.These technical measures improved the quality and efficiency of the sewage network and provided a useful reference for sewage network in other cities.
