【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.更多还原

【Abstract】 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 BrO^-₃ 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 full-scale study indicates a very effective strength and performance of catalytic ozonation in controlling BrO^-₃ formation and it is able to suppress BrO^-₃ formation potential by 51.7% on average.更多还原
