摘　　要：本文研究了金属离子Cu2+及电流对微生物降解有机物(C6H12O6)的影响,开发了外加电场作用下活性污泥法处理含Cu2+有机废水的新型工艺。试验结果表明:Cu2+对微生物降解有机物有明显的抑制作用;50mA的电流对微生物活性没有影响,100mA的电流对微生物活性有明显的抑制作用;对C6H12O6含量为500mg L,Cu2+含量为10mg L的重金属离子有机废水,在曝气池两侧上加电场,电流强度为50mA,经处理后,出水C6H12O6质量浓度为20mg L～30mg L,Cu2+质量浓度为0 5mg L,达到国家废水排放标准。The effect of heavy metal ions and electricity on degradation of organic compound by microbe is studied in this paper.A novel technology to dispose organic wastewater containing heavy metal ions by adding outer electric field to the activated sludge system is developed.The results show:microbe activity is strongly restrained by Cu2+;when outer electricity intensity is 50mA,microbe activity is not influenced,but it is restrained when outer electricity intensity is 100mA.Wastewater containing 500mg/L C6H12O6 and 10mg/L Cu2+(mass concentration)has been disposed in a activated sludge system added 50mA outer electricity intensity.After disposal,the concentrations of C6H12O6 and Cu2+ in the egress water are 20mg/L～30mg/L and 0.5mg/L,respectively,which reach the national standard of discharge wastewater.
