- Abstract:
- The commissioning process of upgrading and reconstruction project in Wenzhou South wastewater treatment plant (WWTP) is summarized, and the influent and effluent quality data of each main processing unit during the commissioning process are analyzed. The results show that coupled control of internal reflux and carbon source dosing can effectively improve carbon source utilization, biological nitrogen removal efficiency and reduce operating costs. In addition, the efficiency of biological phosphorus removal can be effectively improved by controlling the proportion of external reflux and monitoring the ORP in the anaerobic tank. The effluent quality of the nitrogen and phosphorus removal process which takes improved Bardenpho process, secondary sedimentation tank, and Densadeg clarifier as the core process, can meet standards for new municipal wastewater treatment plants in the Discharge Standard of Major Water Pollutants for Municipal Wastewater Treatment Plant (DB 33/2169-2018) in Zhejiang Province.
