摘　　要：以Ti/Fe层柱累托石为粒子电极,利用多相三维电极技术,对含硝基苯废水进行了电催化降解的研究.实验结果表明,质量浓度为150 mg·L-1左右的含硝基苯废水在20 V电压下经1.5 h的电催化降解,硝基苯去除率可达97.75%,COD去除率达80.66%.考察了Ti/Fe层柱累托石的加入量、电解槽电压、底物的浓度、pH值等因素对硝基苯及COD去除率的影响.Present study was to report electrical degradation of nitrobenzene by three -dimensional electrodes. By initiating with 20 voltage direct current, the nitrobenzene degradation ratio higher than 97.75% and COD removal centration reduction of about 80. 66% were observed during a period of 1.5 hours in the presence of filler electrodes. Variety of operating, such as conductivity, cell voltage, pH value, initial concentration of substrate, were discussed in detail to ascertain their respective effect on the treatment efficiency.
