Research on the Drinking - and Waste - Water Treatment with Adsorptive Ozonation for its Practical Use

模型实验表明，利用USY沸石进行吸附臭氧氧化，通过将苯酚吸附到USY微孔中，促进了苯酚的分解。同时共存的Br-的氧化作用没有增强，说明USY沸石吸附臭氧氧化苯酚是可行的。而苯酚溶解在河水中，臭氧化速率降低。此外，usy填料床的苯酚吸附能力随总河水负荷的增加而降低。研究了2-甲基异龙脑（2-MIB）在USY沸石填充床上的突破特性。结果表明，河水的共存缩短了2-MIB的突破时间。河水的臭氧化降低了这种缩短作用。河水间歇吸附实验表明，溶解在河水中的三卤甲烷形成势（THMFP）被USY沸石吸附。长期河水吸附臭氧化处理实验表明，USY吸附臭氧化对河水中溶解的THMFP和黄腐酸类化合物有较好的分解效果。同时还观察到随着时间的推移，分解活性的下降。

A model experiment revealed that the adsorptive ozonation using USY zeolite enhanced the phenol decomposition by means of the adsorptive concentration of phenol into USY micropores. And the oxidation of coexisting Br- was not enhanced, suggested that the selective ozonation of phenol is possible by adsorptive ozonation using USY zeolite. While, the ozonation rate was decreased for phenol dissolved in river water. Furthermore, the phenol adsorption capacity was decreased with increase in total river water loading for the USY-packed bed.The breakthrough characteristics of 2-methylisoborneol (2-MIB) for USY zeolite packed bed was also investigated. The results suggested that the coexisting of river water shortened the breakthrough time of 2-MIB. And this shortening effect was decreased by the ozonation of river water.Batch adsorption experiment using river water suggested that the trihalomethane formation potential (THMFP) dissolved in river water adsorbed on USY zeolite.The long-term adsorptive ozonation treatment experiment using river water suggested that the adsorptive ozonation using USY was effective for decomposition of THMFP and fulvic acid like compounds dissolved in river water. And the deterioration of the decomposition activity with time elapsed was also observed.
