摘　　要：采用电絮凝和O3氧化两步法处理石化工业污水,分别对电絮凝和O3氧化的实验条件(包括电极材料、pH值、电解质的加入量、电解电压、电解时间、通气时间和气体流速等)进行了优化。于所选的最佳实验条件下对石化工业污水进行处理,有机污染物的去除率达98.79%。此外,还对电絮凝-O3氧化过程的作用机制进行了初步探讨。An electrocoagulation-O3 oxidation method has been used to treat the organic pollutants m petrochemical wastewater. Key experimental conditions including the electrode material, the pH of the wastewater, the quantity of electrolyte added, voltage, electrolytic time, aeration time and gas flow rate were optimized. Under the optimal experimental conditions, the elimination efficiency of organic pollutants from petrochemical wastewater reached 98.79 %. The mechanism of the electrocoagulation-O3 oxidation process is discussed briefly.
