摘要/Abstract

摘要： 本文提出一种基于三维电极电化学反应器处理有机废水的新技术 ,结果表明 :该反应器能有效地去除苯胺 ,但其去除率受外加电压、溶液中Fe2 +的浓度、pH值及处理时间 (t)的影响较大 .该项技术处理有机废水效果明显 ,主要是基于电致过氧化氢 ,在Fe2 +存在情况下迅速生成对有机物有很强氧化作用的羟基自由基 .通过ESR法测出了在该电化学反应器处理废水过程中产生的羟基自由基

Abstract: The electrochemical degradation of aniline was investigated using a novel electrochemical reactor, three_dimensional electrode reactor. The experimental results indicated that the reactor could efficiently remove aniline. The removal efficiency could be attributed to a combination of direct and indirect electrochemical reactions,that is,anodic oxidation and oxidation of electrogenerated H 2O 2 and hydroxyl radicals generated in electro_Fenton process. It was also observed that the removal efficiency was significantly dependent on applied voltage,Fe 2+ concentration,pH value and electrolysis time. In the experimental range they all have a positive effect on the removal efficiency except for pH value. Furthermore,hydroxyl radicals generated in electro_Fenton process was confirmed whith the method of spin_trapping ESR.
