| 摘 要： | 考察了厌氧/好氧/缺氧(A/O/A)工艺处理焦化废水对COD和NH3-N的去除效果。连续试验表明,焦化废水进水CODCr、NH3-N平均浓度分别为2 450 mg/L、121 mg/L,在经过系统稳定运行处理后出水浓度分别为115 mg/L、10.6 mg/L,去除率分别为95.3%、91.2%,达到了《污水综合排放标准》的二级标准。将厌氧池和缺氧池内的出气作为气源放回曝气池中,在缺氧环境下形成气升循环。好氧池为气提升三相循环流化床结构,不设沉淀池,MLSS高达10~12 g/L。

| Abstract: | The anaerobic/anoxic/aerobic(A/O/A) process was used for treating coking wastewater,and the removal efficiencies of COD and NH3-N were investigated.The continuous experiment indicates that after stable operation the effluent CODCr and NH3-N are 115 mg/L and 10.6 mg/L while the influent CODCr and NH3-N are 2 450 mg/L and 121 mg/L,respectively.The removal rate of COD and NH3-N are 95.3 % and 91.25%,respectively,meeting II grade of Standard Integrated of Wastewater Discharge.The gas was gathered from anaerobic... |
