摘要：

以硝基苯为代表性有机污染物 ,对比了臭氧化和O3/H2 O2 高级氧化工艺对水中硝基苯的去除效果 .发现与臭氧化相比 ,O3/H2 O2 高级氧化工艺可以显著地提高水中硝基苯的去除效率 .无论在臭氧化还是在O3/H2 O2 高级氧化工艺中 ,水中硝基苯的降解都主要是由OH·完成的 .通过考察O3/H2 O2 高级氧化工艺去除水中硝基苯的影响因素发现 ,在O3和过H2 O2 投量相同的条件下 ,多次投加O3和催化剂H2 O2 对水中硝基苯的处理效果明显优于一次性投加 ;在本次试验条件下 ,O3/H2 O2 高级氧化工艺降解蒸馏水和自来水中硝基苯的最优H2 O2 与O3摩尔比均为 0 5 ,HCO- 3碱度水平 (以CaCO3计 )在低于 1 0 0mg/L范围内对去除硝基苯无显著影响
