摘　　要：目的比较三维电极法与二维电极法对苯酚废水的处理效果.方法采用自制三维电极和二维电极反应器,以苯酚水样为处理对象,通过试验分析两种方法中各因素对苯酚废水处理效果的影响.结果在相同条件下,三维电极反应器对苯酚的去除率比二维电极反应器对苯酚的去除率高10%以上,对pH值的要求低于二维电极,可以处理质量浓度相对较高的苯酚废水,反应电压和电解时间、电解质投加量等因素均低于二维电极法.结论三维电极法极大地节约了处理成本,处理效果优于二维电极法.In order to compare the effect of the treatment of phenol wastewater by three dimension electrode method and two dimension electrode method, a selfmade three dimension electrode and two dimension electrode reactor are used to treat phenol water sample for the purpose of analyzing how various factors influence the effect of the treatment of phenol wastewater. The results of the experiment show that the three dimension electrode method has enormously saved the processing cost, and the request of PH is lower than the two dimension electrode, and it can process phenol wastewater with relatively high concentration. The reaction voltage, electrolyte time and addition quantity of electrolyte and other factors are all lower than those when the two dimension electrode method is used. Under the same conditions, the three dimension electrode reactor on the removal rate of phenol has increased more than 10% than that of the two dimension electrode reactor. Three dimension electrode is better than two dimension electrode in that the activated carbon particles electrodes play an important role in the experimentation.
