摘　　要：本试验采用自行设计的电凝聚污水处理装置,对含重金属污染物的综合废水进行处理,废水处理能力为1m3/h。结果显示:电凝聚法处理后的出水水质达到污水综合排放标准,对铜、锌、铬等重金属的平均去除率在94%以上,乳化油的平均去除率在99%以上,COD的平均去除率在92%以上;试验装置对进水的流量负荷具有较好的耐冲击性;经济分析结果为,电耗和运行费用分别为1.1kw.h/m3和0.65元/m3。The study was carried out hy using electro- coagulation method to treat the heavy metal complex wastewater, the capacity is 1m^3/h. The results show that the effluent quality can meet the requirement of discharge standard, the average removal rates of Cu, Zn, Cr are ahove 94%, emulsion oil removal rate is up to 99 %, the COD removal rate is above 92%. The equipment is able to undertake the hydraulic loading shock,and economic analysis shows that the energy consumption and running cost are 1.1 kw. h/m^3 and 0.65 Yuan RMB/m^3 , respectively.
