摘　　要：国内较多城市的污水主干管网普遍存在高水位运行的现象,管网的问题诊断非常困难,影响运营及维修工作,无法有效保障污水收集与输送。文章结合东莞市区污水主干管网问题诊断项目实践,综合采用现场摸查、河道降水位、水位及水质在线监测大数据分析等多源信息融合创新的方法,对市区污水处理厂主干管网的运行状况进行评估,查找管网系统的缺陷点。项目共查明河道与污水管网联通点83处,管道堵塞严重3处,管道外水入渗较大3处,有力指导运营及维修工作。通过诊断方法的多样化与融合创新,全面分析高水位运行下污水管网系统问题(管网堵塞、河道与管网联通等问题),可提高诊断的准确性和效率,是实现污水系统提质增效的核心之一。The main sewage pipe network in many domestic cities typically operates at a high water level,posing challenges for diagnosing pipe network issues,impacting operation and maintenance work,and compromising the effective collection and transportation of sewage.Drawing on the experience from the Dongguan main sewage pipe network problem diagnosis project,this study comprehensively employed innovative methods such as on-site investigation,river dewatering and water level monitoring,as well as big data analysis of online water quality monitoring to assess the operational status of the main sewage pipe network supporting urban sewage treatment plants and identify system defects.The project successfully identified 83 joint points between rivers and sewage pipes,3 severe pipeline blockages,and 3 instances of significant external water infiltration into pipelines.These findings effectively guided operation and maintenance activities.By diversifying diagnostic methods through fusion innovation and conducting comprehensive analysis of problems associated with high water level operation in sewage pipe networks(e.g.,blockages in the pipe network or connections between rivers and pipes),the diagnostic accuracy and efficiency can be enhanced a crucial aspect for improving the quality and efficiency of sewer systems.
