摘要
上海石洞口污水处理厂原设计处理规模为40万m~3/d,原主体工艺采用UNITANK工艺。改造后污水处理工艺采用"粗格栅+细格栅+旋流沉砂池+综合池+生物反应池+高效沉淀池+反硝化深床滤池"的全流程工艺配置,多模式运行,出水水质达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)一级A标准后排入长江。
The design capacity of Shidongkou Wastewater Treatment Plant(WWTP) in Shanghai is 400 000 m~3/d with UNITANK process After reconstruction, the wastewater is treated by combined process of thick-case-bar + thin-case-bar + vortex grit chamber + biological reaction tank + efficient sedimentation tank + denitrifying deep bed filter to meet the first level A criteria of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918—2002) before entering the Yangtze River with multimode operation.
