摘　　要：采用活性炭作为自制三维电极反应器中的第三极，并用此电极反应器对甲基橙模拟染料废水的降解进行了实验研究。重点讨论了电压、电解质浓度以及溶液pH等因素对CODCr去除率和甲基橙去除率的影响。研究结果表明：活性炭作为第三极的三维电极反应器对甲基橙模拟染料废水进行降解，甲基橙浓度去除率到达90％，CODCR去除率达到80％。并由此展望了活性炭在三维电极处理染料废水的应用前景。Activated carbon was used as the third electrode in a three-phase three-dimensional electrode reactor which used to degrade the dyestuffs wastewater containing methyl orange. Various parameters influenced removal rate of CODCr and methyl orange have been investigated, such as applied cell voltage, pH value and the concentration of electrolyte. The results indicated that methyl orange removal rate can reach 90% and also CODCr removal rate can reach 80%. which shows the prospects of activated carbon＇s application in the area of wastewater treatment with three-dimensional electrode method.
