- Abstract:
- Many cities in China have been faced with complex water environment problems such as low influent concentration of wastewater treatment plant (WWTP) as well as mixed connection and defects of drainage pipe network. Improving the quality and efficiency of sewage systems is an important measure to solve this challenge. As the first pilot city of Yangtze River protection, Wuhu has achieved remarkable results improving the quality and efficiency of sewage system. In view of the problems in the drainage system of a certain city area, such as mixed connection and defects of the pipe network, insufficient and low?concentration of influent in the WWTP, the sewage system was analyzed and diagnosed based on system analysis method. A series of work such as system investigation, pipe network assessment and repair were carried out, and obvious results were achieved. The influent volume of WWTP increased from 10 000 m3/d to 42 000 m3/d, and the influent COD concentration increased from 80 mg/L to 130 mg/L. The systematic concept and practical experience of the project are analyzed and summarized, which is helpful to provide reference for the subsequent Yangtze River protection and other cities’ sewage system improvement and water environment improvement work.
