摘　　要：以黄铜矿作为颗粒电极,考察了三维电极-电Fenton法处理维尼纶废水的影响因素及处理效果,初步探究反应路径及机理,并与三维电极法、普通Fenton法、普通电解法进行了对比.结果表明在电解时间3.0h、初始pH值为4.0、极板间距为3cm、电流密度为30mA/cm^2、黄铜矿投加量10g/L条件下,水样COD的去除率可达到93.6%,并通过试验证明以黄铜矿为工作电极的三维电极-电Fenton法效果优于三维电极法、普通Fenton法、普通电解法.A three-dimensional-electrode Electro-Fenton Depth coupling method was applied on industrial vinylonwaste-water treatment using mosaic electrode made from brass copper.the reaction paths and mechanisms in equipment waspreliminarily investigated.They were then compared with those of three-dimensional electrode method,commonElectro-Fenton method and common electrolysis method.The results indicated that the removal rate of the volatile phenolCOD achieved93.6%at a electrolysis period of3.0h,initial pH of4.0,electrodes space of3cm,electric current density of30mA/cm2and brass copper dosage of10g/L.By such experiment,the research tried to verify that a three-dimensionalelectrodeElectricity-Fenton Depth coupling method using mosaic electrode made from brass copper ore works moreeffectively than traditional three-dimensional electrode method,common fenton method and common electrolysis method.
