摘　　要：采用Cu^(2+)与Fe^(2+)对ACF进行改性并作为阴极进行电Fenton实验,比较了2种改性与未改性的ACF电极对垃圾渗滤液生化出水的处理效果。结果表明,改性提高了ACF电极处理效果,且质量分数0.5%的Cu^(2+)改性后的处理废水效果优于Fe^(2+)改性。在未添加Fe^(2+)的情况下,系统对渗滤液生化出水COD去除率达89.26%,且避免了铁泥的产生。处理后出水腐殖酸等大分子共轭体系及芳香构化程度明显下降,可生化性得到明显改善。The ACF was modified by Cu^(2+)and Fe^(2+)and used as cathode to conduct electro-Fenton experiment. The treatment effects of two modified and unmodified ACF electrodes on biochemical effluent from landfill leachate were compared. The result showed that the treatment effect of ACF electrode was improved by modification, and the treatment effect of wastewater after modification with mass fraction of 0.5% Cu^(2+)was better than that of Fe^(2+)modification. The COD removal rate of leachate biochemical effluent reached 89.26% without adding Fe^(2+)and the production of iron sludge was avoided. After treatment, the conjugated system and aromatization degree of macromolecule such as humic acid in effluent decreased significantly, and the biodegradability improved significantly.
