摘要
采用MBR工艺对PCB线路板废水进行处理,运行结果表明:在进水COD1500mg/L,Cu2+1.5mg/L,MLSS6000～8000mg/L,DO控制在2～4mg/L,系统温度在20～40℃,停留时间为10h,曝气量在40～43m3/min的污水条件下,MBR系统出水水质良好且运行稳定,COD平均去除率在87%以上,Cu2+平均去除率在70%左右,同时系统具有较强的抗负荷冲击能力。
The practical application of MBR technology in treatment of PCB's wastewater was introduced.The operation results show that the MBR system is stable with quality effluent under the following conditions:the influent COD of 1 500 mg/L,Cu 2+ of 1.5 mg/L,MLSS of 6 000～ 8 000 mg/L and DO of 2～4 mg/L,with the system temperature of 20～40℃,residence time of 10 h and aeration quantity of 40～ 43 m3/min.The average removal rate of COD is over 87% and that of Cu 2+ is about 70%.
