摘　　要：采用生物制剂法和铁氧体法处理重金属废水。在空气氧化40 min,生物制剂添加量为0.2%,处理后pH值为12左右,生物制剂法处理废水中的Cu、Pb、Zn、Cd和As去除率分别达83.48%、74.81%、80.42%、99.85%、99.65%。在添加纳米铁粉,处理后pH值为8.8左右,除砷剂聚合硫酸铁协同作用(Fe/As=10)下,铁氧体法处理废水中的Cu、Pb、Zn、Cd和As去除率分别达89.56%、82.26%、58.26%、99.92%、99.81%。The biological preparation and ferrite methods were applied for heavy metal wastewater treatment.Under conditions of air oxidation of 40 min,biological agents added 0.2%,and point pH value 12,the removal rate of Cu,Pb,Zn,and Cd was 83.48%,74.81%,80.42%,99.85%,and 99.65%,respectively.In the conditions of additions of nanometer iron powder and the end point pH value of about 8.8,the arsenic removal synergistic effect of PFS（Fe/As=10）,ferrite process for treatment of wastewater Cu,Pb,Zn,Cd was up to 89.56%,82.26%,58.26%,99.92%,99.81%,respectively.
