摘　　要：在电镀废水进行处理中引入A2/O-MBR工艺,运行结果表明:在生化段进水COD 250～350 mg/L,氨氮45～60 mg/L,总磷2.0～3.0 mg/L,总铜、总镍、总锌均低于0.5 mg/L,DO控制为2～4 mg/L,硝化液回流比为200%,MLSS在3 500 mg/L左右的运行条件下,MBR出水水质良好且稳定,出水COD、氨氮、总磷、总铜、总镍、总锌分别为45、10、0.8、0.2、0.4、0.4 mg/L。同时该工艺具有较强的抗冲击负荷能力。Anaerobic-anoxic-oxic membrane bioreactor has been applied to the treatment of electroplating waste- water. The operation results show that the effluent water quality of system is good and stable under the following con- ditions：in the biochemical section, its influent COD is 250-350 mg/L, ammonia nitrogen 45-60 mg/L, total phos- phorus 2.0-3.0 rag/L, Cu2＋ less than 0.5 mg/L, Ni2＋ less than 0.5 mg/L, Zn2＋ less than 0.5 mg/L, MLSS 3 500 mg/L, ni- trification liquid reflux ratio 200% and DO 2-4 mg/L. The average effluent COD, NH3-N ,TP, Cu2＋, Ni2＋ ,Zn2＋ are 45,10,0.8,0.2,0.4,0.4 mg/L, respectively. Furthermore ,this process has stronger resistance to impact load.
