Abstract:
The total design capacity of Taiyuan Chengnan wastewater treatment plant (WWTP) upgrading and reconstruction project is 20×104 m3/d, and the effluent standard is raised from first level A criteria specified in the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002) to the Comprehensive Wastewater Discharge Standard of Shanxi Province (DB 14/1928-2019). According to the requirement of the environmental protection department that the WWTP cannot stop water supply during the reconstruction period, the MBBR system is adopted to improve the quality and efficiency without water shutoff based on careful construction organization plan and schedule. During the construction period, all the sewage received by Taiyuan Chengnan WWTP was treated, and the good effect of operation while constructing was achieved.
