- Abstract:
- A new underground wastewater treatment facility with a designed capacity of 50×104 m3/d was built in Bailonggang wastewater treatment plant in Shanghai. The process consists of pretreatment, AAO, high-efficiency sedimentation tank and cloth media filter, and the effluent quality is required to meet the first level A limit specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The actual operation data in 2021 showed that the process demonstrated a good ability to withstand the seasonal fluctuations of influent pollutants, the removal rate of each pollutant was higher than the design value, and the effluent quality was always better than the first level A limit specified in the discharge standard. The assessment results of pollutant removal capacity of the main treatment units based on mass flow analysis showed that the removal rates of pollutants in pretreatment and biological treatment stage all reached the design values.
