- Abstract:
- It is more difficult to meet wastewater discharge standards with influent quality change and treatment equipment damage. Hence, Keqiao Jiangbin wastewater treatment plant (WWTP) in Shaoxing needs to build a new advanced treatment project, which adopts carbon-loaded magnetic coagulation and high efficiency sedimentation process. The design, operation effect, economic performance of the project are elaborated, and then operation management experience is summarized. Since April 2019, it had been running steadily, with the operating cost of about 0.84 yuan/m3, and 14 indicators such as effluent COD, TN, TP could satisfy the direct discharge standard for new WWTP in Discharge Standards of Water Pollutants for Dyeing and Finishing of Textile Industry (GB 4287-2012). The project practice has proved that carbon-loaded magnetic coagulation and high efficiency sedimentation is a good choice for advanced treatment of comprehensive printing and dyeing wastewater.
