| 中文摘要 |
| 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BrO-3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BrO-3的生成能力平均降低了51.7%，能明显抑制BrO-3生成. |
| 英文摘要 |
| An investigation is given to the bromate formation of catalytic ozonation in treating drinking water. It is shown that the c×tvalue 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×tvalue 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. |
