Journal AWWA - Formation and Control of Bromate During Ozonation of Waters Containing Bromide AWWA期刊-含溴水臭氧氧化过程中溴酸盐的形成和控制
发布日期: 1993-01-01
本研究的结果表明,臭氧氧化含溴化物的水可能会产生溴酸盐,臭氧剂量起着关键作用。然而,通过两个或三个腔室对臭氧进行适当分级,有可能将臭氧残留和溴酸盐的形成降至最低,同时仍符合C X T标准。添加过氧化氢(过氧化物法)可能会增加溴酸盐的形成。随着臭氧氧化的pH值降低,满足Cx T标准所需的臭氧剂量降低,生成的溴酸盐减少。作者的结论是,在溴酸盐的形成被完全控制之前,需要更好地理解溴酸盐的形成机制。包括20个参考文献、表格和图表。
The results of this study show that the ozonation of water containing bromide may produce bromate, with ozone dosage playing a critical role. The appropriate staging of ozone through two or three chambers, however, has the potential to minimize ozone residual and bromate formation while still meeting C X T criteria. The addition of hydrogen peroxide (the PEROXONE process) may increase the formation of bromate. As the pH of ozonation was lowered, the ozone dosage necessary to meet C X T criteria dropped, and less bromate was produced. The authors conclude that a better understanding of the mechanisms of bromate formation is required before it can be fully controlled. Includes 20 references, tables, figures.
