摘　　要：研究了饮用水臭氧催化氧化过程中溴酸盐的生成特点与控制效能.结果表明,臭氧衰减过程中c×t值大小与BrO3-生成明显相关.加入臭氧催化剂能使剩余臭氧含量降低60.0%-77.4%,并使臭氧ID反应持续的时间由4.3 min延长至6.8 min,明显降低了臭氧衰减过程中的c×t值.生产运行结果表明,臭氧催化氧化使BrO3^-的生成能力平均降低了51.7%,能明显抑制BrO3^-生成.An investigation is given to the bromate formation of catalytic ozonation in treating drinking water. It is shown that the c × t value of ozone depletion stage plays a more important role in BrO3^- formation. Catalyst addition not only reduces the residual ozone content by 60.0% - 77.4% but also extends the ozone ID stage time from 4.3 min to 6.8 min, which makes the ozone c × t value shorter. A fun-scale study indicates a very effective strength and performance of catalytic ozonation in controlling BrO3^- formation and it is able to suppress BrO3^- formation potential by 51.7% on average.
