中文摘要：

以天津市引滦原水为研究对象，研究了不同臭氧投加量（C）和不同反应时间（丁）条件下预臭氧化工艺对THMFP、HAAFP和溴酸盐等消毒副产物指标的影响。结果表明，引滦原水经不同CT值条件下的预臭氧化处理后，出水THMFP和HAAFP均有一定程度的下降，去除率分别为7．3％-32．2％和3．0％-30．9％；生成的溴酸盐含量均符合国家关于饮用水中溴酸盐含量的要求。当初始臭氧含量为2．696mg／L，反应时间为10min时，预臭氧化出水的THMFP浓度最低：当初始臭氧含量为1．048mg／L，反应时间为20min时，预臭氧化出水的HAAFP浓度最低。

英文摘要：

The raw water from Luanhe River in Tianjin was used to investigate the effects of ozone dosage （C） and contact time （T） during preozonation on disinfection by-products, such as THMFP, HAAFP and bromate. The results showed that THMFP and HAAFP of the outflow decreased under different preozonation CT values. The removal rate of THMFP was 7.3% to 32.2% while the removal rate of HAAFP was 3.0% to 30.9%. The bromated level in the outflow was lower than the maximum contamination level （MCL） of the national standards. The outflow after preozonation had the lowest THMFP value under the initial ozone dosage of 2. 696 mg/L and the contact time of 10 min. When the initial ozone concentration was 1. 048 mg/L and the contact time was 20 min, the HAAFP value of the preozonation outflow was the lowest.
