摘　　要：以黄浦江上游水源为原水,采用运行水量各为1m^3/h的两套中试设备,进行了预臭氧化工艺和预氯化工艺平行对比试验,研究了预臭氧化工艺对水中有机卤代物的去除效果,并对三卤甲烷和卤乙酸两类消毒副产物的致癌风险进行了分析计算,发现预臭氧化可以大大降低致癌的风险性。The comparative pilot experiments were conducted at a scale of 1 m^3/h for each , and the raw water for both preozonation and prechlorination processes took from upstream of HuangPu River. The Effects of Removing Organichaloid compounds from Water by Preozonation are studied. The Cancerogenic risk of trihalomethane and haloacetic acids, two kinds of DBPs ,was calculated and analyzed. The results show that Cancerogenic risk was decreased drastically by preozonation process .
