摘　　要：采用UV、O3和UV/O3联用工艺对水中邻苯二甲酸二丁酯(DBP)的降解效果和降解产物进行研究,探讨了O3初始浓度、DBP初始浓度、pH值等因素对氧化降解DBP的影响.结果表明:UV本身对DBP的去除贡献率不大,UV/O3联用工艺对DBP的去除效果略优于单独O3氧化,提高体系的初始pH值和O3浓度有利于DBP的降解;采用GC-MS分析方法对DBP O3氧化中间产物进行分析,得出DBP可能的降解途径.The degradation characteristics and intermediates of dibutyl phthalate （DBP） in water by the advanced oxidation process O3, UV and UV/O3 were respectively studied. The effects of O3 concentration, DBP concentration and pH on the removal rate of DBP were investigated. The experimental results show that UV is not able to remove DBP significantly. However, O3 or the combination of O3 with UV could degrade DBP effectively. Both the increase in the O3 concentration and the initial pH value of the system benefit the DBP removal. In addition, the oxidation intermediates of DBP in the O3 treatment system were analyzed by using GC-MS, and the detailed degradation path was illuminated.
