由于臭氧具有更高的消毒能力，许多公用事业公司正在研究将其用作主要消毒剂。然而，包括臭氧在内的所有氧化剂都会与水中的天然有机物（NOM）发生反应，形成消毒副产物（DBP）。地表水中溴的存在会导致溴酸盐的形成，溴酸盐是臭氧氧化过程中产生的一种DBP，也是一种可疑的致癌物。本文报告了加拿大安大略省温莎市温莎公用事业委员会（WUC）开展的一项研究的结果，该研究旨在改进WUC的a.H.Weeks工厂采用预混凝臭氧氧化的消毒过程。研究目标包括:评估该工厂底特律河原水水源中的溴含量；预处理过程中溴酸盐生成的评估- 四种臭氧剂量（1.2、1.3、2和3 ug/L）下的混凝臭氧氧化；评估不同初始溴浓度下溴酸盐的形成；评估两次接触时间（6.5和9分钟）的溴酸盐形成情况；建立溴酸盐形成与Ct值之间的关系。包括17个参考文献、图表。

Many utilities are now investigating the use of ozone as a primary disinfectantdue to its higher disinfection capabilities. However, all oxidants, includingozone, react with natural organic matter (NOM) in water to form disinfectionbyproducts (DBPs). The presence of bromide in surface waters can lead to theformation of bromate, a DBP produced during ozonation, and a suspectedcarcinogen. This paper reports the results of a study undertaken by the WindsorUtilities Commission (WUC) of Windsor, Ontario, Canada, to improve thedisinfection process using pre-coagulation ozonation at WUC's A.H. Weeks Plant. The study objectives included: evaluation of the amount of bromide in the raw water source for the plant, the Detroit River; evaluation of bromate formation during pre-coagulation ozonation at four ozone dosages (1.2, 1.3, 2 and 3 ug/L); evaluation of bromate formation at various levels of initial bromide concentrations; evaluation of bromate formation for two contact times (Ct) (6.5 and 9 minutes); and establishment of a relationship between bromate formation and Ct values.
