Abstract:
Suzhou is faced with the new requirements of implementing the "Suzhou Special Emission Limits". It conducts historical data analysis, full-process functional test analysis, and full-process simulation test analysis on sewage treatment plants, and clarifies the key points of process management and project upgrading. The operation results after the implementation of the project showed that the project could effectively improve the effluent quality of the sewage plant. The removal rates of COD, BOD5, SS, TN, NH3-N, and TP were 89.8%, 95.2%, 95.8%, 79.4%, 94.4% and 93.3%. The effluent quality could stably meet the discharge standards. The project investment was about 3.28 million yuan, and the operating cost increased by 0.57 yuan per ton of water. This method can offer useful information for the optimization of operation and transformation of the same type of sewage plants.
