摘　　要：研究了使用臭氧和二氧化氯氧化去除水中石油类污染物 ,确定了最佳投加最、反应时间、pH对去除率的影响 ,同时进行了臭氧和二氧化氯的对照实验 .分析了ClO2 和O3 在水处理应用中的特点 .实验结果表明 ,臭氧对石油类污染物的氧化速度快 ,净化能力强 .二氧化氯的氧化能力虽比不上臭氧 ,但仍然可以有效去除水中石油类污染物 ,同时可以抑制“三致”物质的形成 ,加之价格低廉 ,在水处理中有着广阔应用的前景 .The paper mainly discussed the removal efficiency of petrochemical pollutants through oxidation reaction by using ozone and chlorine dioxide. The factors affecting the removal rates, such as optimal dosage, reaction time, pH etc., are determined. The comparative tests between ozone and chlorine dioxide are carried out for summarizing the characteristics of the two oxidants in water treatment application. The experimental result indicats that ozone shows high reactive rate and strong oxidation capability while chlorine dioxide owns enough efficiency to clean petrochemicals although its oxidation capacity seems weaker than that of ozone. Chlorine dioxide can restrain the formation of cancerogenic substances, besides, it is of low costs. Therefore, it has the potential application in water treatment.
