摘　　要：武汉市黄孝河机场河项目建有全国最大的合流制溢流污染调蓄及一级强化处理设施群。其中机场河合流制溢流污染调蓄及一级强化处理设施用于调蓄和处理雨季时机场河明渠起端的合流制溢流污水,调蓄规模为10×10^(4)m^(3),一级强化处理设施规模为4 m^(3)/s。采用细格栅、曝气沉砂池、高效沉淀池、精密过滤设备、紫外消毒等处理工艺,具有占地面积小、间歇运行和启动快速的特点。运行结果显示,出水水质可稳定达到设计标准,出水COD、SS和TP的平均浓度分别为53.07、4.28、0.35 mg/L,去除率分别为28.9%、92.2%和72.8%;综合运营成本为0.363元/m^(3)。The Huangxiao River and Jichang River Project in Wuhan has the largest combined sewer overflow(CSO)regulation and primary enhanced treatment facilities in China.Of which,the Jichang River CSO storage tank and primary enhanced treatment plant are used to treat the CSO that accumulates at the beginning of the Jichang River open channel during the rainy season.It has a storage capacity of 10×10^(4)m^(3)and a primary enhanced treatment capacity of 4 m^(3)/s.Fine grid,aerated grit chamber,high efficient sedimentation tank,precision filtration equipment,and ultraviolet disinfection processes are employed in this facility.The system is characterized by a small footprint,intermittent operation and fast start-up.According to the operation results,the average effluent concentrations of COD,SS,and TP are 53.07 mg/L,4.28 mg/L and 0.35 mg/L,and the removal rates are 28.9%,92.2%,and 72.8%,respectively.The effluent quality consistently satisfies the design standards,and the comprehensive operating cost is 0.363 yuan/m^(3).
