| 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.

| Abstract: | For three organic contaminants with different activities to ozone,a simple control method of suitable dosage of H_2O_2 for O_3/H_2O_2 advanced oxidation process was established.The experimental results showed that existing ozone in water was a necessary condition for O_3/H_2O_2 to promote the degradation efficiency of ozonation,and that suitable dosage of H_2O_2 was dependent on the reactivity of organic with ozone directly.The suitable dosage of H_2O_2 for different organic contaminants degraded by O_3/H_2O_2 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 O_3/H_2O_2 in wastewater treatment. |
