The Yangtze River protection is an important environmental protection strategy for China, and the quality and efficiency of the sewage system is also one of the environmental protection actions that China is working hard to implement in recent years. As the first batch of pilot cities for the protection of the Yangtze River, Wuhu City has significantly improved its sewage system through a series of comprehensive sewage system improvement engineering measures. This paper briefly described the general situation and measures of the sewage system renovation project in the CD area of Wuhu City, and based on the systematic thinking of “source-network-plant-river”, the performance of improving the quality and efficiency of the sewage system was evaluated. With the implementation of the sewage system remediation project, the water quality at the source and discharge outlet as well as the water quantity of sewage collected had been greatly improved. The sewage collection volume had been increased from 10,000 m3/d to 42,000 m3/d and the COD concentration of the influent has increased significantly. The introduction and analysis of this project may provide some reference for other similar sewage system remediation projects in China and other countries and regions.
