摘　　要：根据三维电极体系中电流特征引入了反应电流与体系电流之比(β),结合物质守恒定律以及法拉第定律建立了反应电流效率表达式,并依此建立了三维电极体系反应动力学模型。分别以DSD酸、促进剂M、聚乙烯聚合引发剂3种典型废水为研究对象,控制电流密度分别为5～16、20～60和80～350A/m2,考察相应的有机物降解效果及电流效率。结果表明,实验数据与理论拟合具有较高的相关性,F值检验说明动力学模型高度显著。建立的反应电流效率表达式和动力学模型可作为三维电极体系优化设计与控制的依据。According to laws of indestructibility of matter and Farady, the description of current efficiency and kinetic model were evaluated by introducing the ratio of the Faradaic current to the total cell current （β） through the network analysis of three dimension electrode system （TDE）. The electrooxidations of 4, 4-diaminostilbene-2, 2-disulfonic（DSD） acid, 2-mercaptobenzothiazole （M） and polyethylene polymerization initiator wastewater were studied to investigate the degradation effect and current efficiency, respectively. Experimental results obtained by using a TDE at current density ranging from 5 to 16 A/m2, 20 to 60 A/m2 and 80 to 350 A/m2, respectively, for the three kinds of typical industrial wastewater were in good agreement with the proposed equation. Being verified by F value, the kinetics model had higher significance level. Accordingly, the description of current efficiency and kinetic model could be used for the optimal design and manage of TDE.
