- Abstract:
- In order to implement the national policy requirements such as Water Pollution Control Action Plan, enhance the sewage treatment efficiency and improve the water environment quality, the local discharge limits of major pollutants in key basins and region of China have been formulated one after another, which are all higher than that of the first class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Through large-scale systematic investigation and analysis, the common difficulties of upgrading include how to find out the background effectively, identify the current situation, and put forward the technically feasible and economically reasonable countermeasures. In this paper, the “four in one” accurate diagnosis technology method is systematically constructed, covering the four closely connected and back-to-back operation steps of “problem preliminary screening-difficulty analysis-system diagnosis-application verification”, the key objectives and implementation plan of each step are put forward systematically, and the system application of the systematic and accurate diagnosis technology in Changzhou Jiangbian WWTP is introduced. The technical method has been included in the upgrading policy guidance documents issued by Jiangsu, Guangdong and other provinces, which provides systematic technical support for the upgrading construction and refined operation management of urban wastewater treatment system in China.
