Influence of Catalytic Ozonation Process on Suppressing Bromate Formation Potential in Drinking Water Treatment
臭氧催化氧化抑制溴酸盐生成效能的研究

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 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 4.3min to 6.8min, which make the ozone C×T value shorter. A full-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.
