Study on Process Selection for Sewage Treatment Plant Expansion Project

Abstract： Sewage treatment plants are a critical component of urban water systems， and their scale is influenced by factors such as social production， residents’ livelihoods and economic development speed. Based on the current sewage treatment process and effectiveness of the sewage treatment plant， as well as future sewage treatment needs， the sewage treatment process for the expansion project has been designed， and the key technologies adopted in the main links have been explained. The research results can provide reference for the selection of subsequent sewage treatment processes.
