摘　　要：实验研究了以Ir-Ru-Sn掺杂电极为阳极、不锈钢板为阴极的电催化降解模拟苯酚废水。分别考察了废水初始pH值、极板电压、极板间距、初始液的浓度及曝气等因素对电催化处理效果的影响。实验结果表明,Ir-Ru-Sn掺杂电极对苯酚的电催化降解具有很好的适应性;降解特征为表观一级动力学;曝气的存在可以有效提高传质动力,但对苯酚的降解率的提高贡献不大。采用该电极时适宜的工艺条件是:初始液的pH值为3,极板电压为36V,极板间距为1.0cm,反应时间为180min,在此条件下苯酚的去除率达到了97.97%以上。The degradation of stimulated phenol wastewater by electrocatalysis which took Iridium-Ruthenium-Stannum(Ir-Ru-Sn)doped electrode as anode and stainless steel plate as cathode was studied in the experiment. The influences of initial pH,plate voltage,plate distance,initial solution concentration aeration etc. on the performance of electrocatalysis were investigated respectively.The experimental results show that,the Ir-Ru-Sn doped electrode had very good adaptability to the electrocatalytic degradation ofphenol;the degradation fit first-order kinetics equation;the aeration could increase the mass transfer power effectively,but contributedlittle to the increase of phenol degradation rate. The appropriate process conditions for this electrode were:the pH value of initialsolution was 3,the plate voltage was 36V,the plate distance was 1. 0cm,andthe reaction time was 180min,which allowed the removalrate of phenol up to over 97. 9%.
