摘　　要：垃圾渗滤液生化处理后的尾水COD_(Cr)浓度约为400～800 mg/L,因其可生化性较差,所以通过传统办法很难进一步降低出水COD_(Cr)浓度,为使其能直接排放自然水体,本课题采用"铁碳微电解-Fenton氧化-混凝沉淀"组合工艺处理垃圾渗滤液生化处理后的尾水,处理后的垃圾渗滤液尾水COD去除率可达71.4%,接近国家污水综合排放一级排放标准。The CODCr is about 400-800 mg/L of the landfill leachate tailwater which is already treated by biological processes. As the low hiodegrability, it＇s very difficult to further deduce the CODCr by traditional ways. In order to meet the standard of discharging to nature water, the tailwater is advanced treated by ironcarbon micro-electrolysis, Fenton oxidation and coagulation-sedimentation. The removal of CODCr is up to 71.4 %, and the CODc~ value of effluent is close to class one of ＂Integrated Water Discharge Standard＂ （GB 8978--1996）.
