Operation Status and Optimization Countermeasures of Drainage System in Shanghai Central City
Taking the drainage system of Shanghai central city as the research object,this paper analyzed the changes of water quantity,water quality,discharge and reduction amount of COD in each area by collecting the operation data of the drainage system of three major sewage areas of Bailongang,Zhuyuan and Shidongkou in the region from 2016 to 2021.The results show that the water inflow,concentration of influent COD and BOD5,and COD reduction in the three major sewage areas showed an increasing trend,while the COD discharge showed a decreasing trend by taking measures such as exploring the treatment capacity of the wastewater treatment plant,optimizing the trans-portation and scheduling of the pipe network and adjusting the wastewater treatment process.At the same time,the current situation of the drainage system in Shanghai central city was summarized,which mainly has problems of in-sufficient terminal sewage treatment capacity,weak linkage between regions,pipe network maintenance and the systematic and refined management level needs to be improved,corresponding countermeasures were put forward to provide reference for improving the safe operation capacity of the drainage system in Shanghai central city.
