This paper is designed for the sewage treatment process of Shaowu City Second Sewage Treatment Plant, focusing on the modified card oxidation ditch process. This sewage treatment plant is mainly purified by living sewage in Shaowu City, and the processing scale is 10,000 m3d-1. According to the sewage quality and the reality of urban development, this paper selects the hydrolyzate + oxidation ditch + concrete precipitation process. The sewage first hydrolyzedate the acidified tank before entering the secondary treatment to increase the sewage’s sewage, then remove the main organic matter in the water and complete the nitrogen removal phosphorus. Finally, further remove the suspension in water. The material and total phosphorus have enabled water quality to meet the “Sewage Treatment Plant Pollutant Emission Standard” (GB18918-2002). The project is expected to invest 3001,500 yuan, and the wastewater operating cost of the equivalent is 0.57 yuan/ton.
