摘　　要：随着臭氧氧化工艺应用的日益广泛,其产生的致癌性副产物——溴酸盐也倍受关注。该文从溴酸盐的产生影响因素及去除方法两个方面来研究溴酸盐的控制技术,发现溴离子、臭氧、氨氮及有机物浓度都将影响溴酸盐的生成;此外,活性炭及其与零价铁粉的组合都能较有效的去除溴酸盐,而UV/TiO2能更快速彻底地去除溴酸盐。With the popularisation of ozonation, bromate, a carcinogenic hyproduct, has been widely concerned. Control technique of bromate was studied by studying the formation impact factors and removal methods of bromate. Results show that bromine, ozone, ammonia nitrogen and concentration of organic matter can affect the formation of bromate. It is also found that activated carbon and the combination of activated carbon and zero valent iron powder can remove bromate effectively. Meanwhile, UV/Ti02 can remove bromate more rapidily and completely.
