| 摘 要： | 以硝基苯为目标反应物,对臭氧/分子筛氧化和单独臭氧氧化去除水中微量有机污染物的效果进行了比较.发现与单独的臭氧化相比,臭氧/分子筛氧化工艺可以提高水中硝基苯的降解效果.在该实验条件下,单独臭氧氧化和臭氧/分子筛氧化对硝基苯的去除率都随着温度的升高而增加,随着pH值的升高越来越大;此外还考察了微波对臭氧/分子筛体系降解水中微量硝基苯的作用,结果表明微波具有明显协同臭氧/分子筛体系催化降解硝基苯的作用,其协同作用机制可能是促进了羟基自由基的生成.

| Abstract: | The effect of removing organic trace infectant from water was compared between ozone/molecular sieve oxidation treatment and ozone oxidation treatment and the target reactant was nitrobenzene.It was identified that ozone/molecular sieve oxidation treatment could improve the degradation effect of nitrobenzene in water.The removing rate increased with the increase of temperature and pH in the condition of this experiment.Besides,the microwave'sfunction on the degradation of trace nitrobenzene in water with the ozone/molecular sieve oxidation treatment method was analysed and it was showed that microwave could obviously cooperate with ozone/molecular sieve oxidation treatment system to catalysing and degradation the nitrobenzene in water.The mechanism of cooperation may be that microwave could accelerate the production of hydroxyl group free radical. |
