摘　　要：讨论了阴极电芬顿体系中电极材料的选择标准,并通过比较选择以钛涂钌铱电极、活性碳纤维电极作为阳极、阴极材料。利用自制的电芬顿反应器,对影响体系处理印染废水效果的各相关因素进行研究。结果表明:阴极电芬顿法处理印染废水效果良好,最佳反应条件:pH值为3,FeSO4投加量为150 mg/L,曝气量为0.1 m3/h,电压为9 V,反应时间为40min,此时COD的去除率最高,可达到73.5%。The selection criteria of electrode material in EF-Fenton system was discussed, and by comparing the performance, titanium coated ruthenium iridium electrode was selected as the anode material, ACF electrode as the cathode material. A self- made Electro-Fenton reactor was used to treat printing wastewater, the effects of various factors on the treatment of printing wastewater were experimentally analyzed. The results show that the EF-Fenton system is effective in the treatment of printing wastewater, and the optimal reaction conditions are as follows： reaction pH value of 3, FeSO4 dosage of 150 rag/L, aeration capacity of 0.1 m3/h, voltage of 9 V, time of 40 min. The maximum removal rate of COl） reaches 73.5%.
