中文摘要：

研究了臭氧（O2）和过氧化氢（H2O2）联用技术对水中邻苯二甲酸二甲酯（DMP）的去除。利用小试试验确定了投加H2O2的工艺参数和相关因素的影响，在中试系统中模拟DMP污染，考察了联用工艺应用于实际水体的除污染效果。小试结果表明，在H2O2／O2的最佳摩尔比为0．6：1时，可以有效提高水中DMP的去除率。同时影响因素考察发现，随反应温度升高去除率升高，pH值在中性范围内对DMP有较好的去除效果，叔丁醇对DMP的去除表现出抑制作用。中试结果表明，在最优工艺参数条件下，O2／H2O2有效地提高了有机物的去除效能，对饮用水中μg级DMP有很好的控制作用，可以作为一项给水深度处理技术。

英文摘要：

The removal of dimethyl phthalate in the drinking water was studied by the combination of O3/H2O2 treatment processes. The lab-scale experiments were carried out to get the optimal parameters of the addition of H2O2 and the related effects were also studied. The removal efficiency of model compounds （DMP） in the natural water was investigated in the pilot-scale plant. The results demonstrated that the process O3/H2O2 can effectively elimi- nate DMP in the water, with the best ratio of/-[2O2/03 to be 0. 6 ： 1. The DMP removal rate elevated with the tem- perature increasing and good performance could be obtained under the neutral pH condition, while tert-butyl alcohol obviously reduced the rate of DMP removal in the water. The results obtained under the optimal parameters in the pilot-scale plant showed that the combination process of O3/H2O2 can make a good performance on the effective removal of organic matter, especially DMP in μg level of the drinking water.
