中文摘要：

对与臭氧有着不同反应活性的3类有机污染物，探讨并建立了O3／H2O2高级氧化技术H2O2较优投加量的简易控制方法。结果表明，水中存在溶解臭氧是H2O2与臭氧降解效率具有协同作用的必要条件，另外，H2O2的较优加入量直接依赖于目标有机污染物与臭氧的反应活性。对于不同的有机物及在常规的臭氧化水处理时间内，H2O2加入量控制在单独臭氧化处理时水中溶解臭氧的20-30倍（质量比）之间为宜。这种简易控制H2O2加入量的方法对推广O3／H2O2技术在实际废水处理中的应用具有重要的意义。

英文摘要：

For three organic contaminants with different activities to ozone, a simple control method of suitable dosage of H2O2 for O3/H2O2 advanced oxidation process was established. The experimental results showed that existing ozone in water was a necessary condition for O3/H2O2 to promote the degradation efficiency of ozonation, and that suitable dosage of H2O2 was dependent on the reactivity of organic with ozone directly. The suitable dosage of H2O2 for different organic contaminants degraded by O3/H2O2 must be controlled within 20 - 30 times of dissolved ozone concentration （mass ratio ） within 30 - 60 min of routine time in ozonation of wastewater. This simple control method is highly significant for the application of O3/H2O2 in wastewater treatment.
