- Abstract:
- The three-year action to improve the quality and efficiency of urban sewage treatment has been fully launched. Yangzhou City has carried out a CCTV inspection on the sewage pipe network, and comprehensively investigated the problems including residual wall, chiseling, interface falling off, rainwater and sewage connecting pipe. Through the excavation and trenchless repair of sewage drainage pipeline, the indexes of water inflow, COD and BOD5 of Tangwang and Liuwei sewage treatment plants in Yangzhou have been increased significantly compared with those before repair of the sewage drainage pipeline, and the treatment efficiency of the plants has been significantly improved. Based on this project, Yangzhou takes the lead in establishing a data collection and management system of sewage pipe network in Jiangsu Province, which is convenient for query and management. It collects massive high definition detection video and surveying and mapping data, and develops query, statistics, analysis and other functional modules according to the needs of users at all levels, resulted to an efficient facilitation of the dynamic update and management. Meanwhile, this work lays a good foundation for the installation of the internet of things terminal perception device as well as flow and water quality sensors for the novel sewage pipe network system in future. This paper investigated the critical issues in the selection of sewage pipe materials, closed water test and CCTV detection of sewage pipe network, which provides reference for other cities to carry out sewage quality improvement and efficiency enhancement.
