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 the electrode materials in the cathode Fenton system are discussed. The electrode materials of the anode and the cathode are coated with ruthenium-iridium (ITO) electrode and activated carbon fiber electrode by comparison. The use of home-made Fenton reactor, the impact of the system to deal with the effect of printing and dyeing wastewater were all related factors. The results showed that cathode Fenton process was effective in treating printing and dyeing wastewater. The optimal reaction conditions were as follows: pH 3, FeSO4 dosage 150 mg / L, aeration rate 0.1 m3 / h, voltage 9 V, reaction time For 40min, COD removal rate at this time the highest, up to 73.5%.
