This project is the Jimunai County drainage engineering sewage treatment plant project. It is a project using an Asian Bank loan. The construction unit of the project is the Jimunai County Housing and Urban-Rural Development Bureau. The design scale of the sewage plant is 500 cubic meters per day. It adopts a typical treatment process based on the aeration and oxidation ditch process, and chlorine dioxide is used for terminal disinfection. The effluent standard of the sewage plant is the second-level standard of the "Pollutant Discharge Standard for Urban Sewage Treatment Plants" (GB18918-2002.).
