Journal AWWA - Factors Affecting DBP Formation During Ozone-Bromide Reactions AWWA期刊-臭氧溴化反应中影响DBP形成的因素
发布日期: 1993-01-01
臭氧氧化含有溴离子的水会导致有机和无机副产品的形成。副产物的形成受溴离子浓度、有机前体的来源和浓度、pH值、臭氧剂量、温度和碱度的影响。有机和无机副产物均随着溴离子浓度的增加而增加,但随着碱度的增加而减少。发现有机副产物随着pH值的降低而增加,而高pH值有利于溴酸盐的形成。一般来说,随着臭氧剂量的增加,溴仿浓度先增加,然后减少。 臭氧氧化和培养温度对溴仿和溴酸盐的形成都有积极影响。与有机副产品的形成相比,PEROXONE似乎更倾向于溴酸盐的形成,而氨的添加减少了溴酸盐和有机副产品。包括22个参考文献、表格和图表。
Ozonation of waters containing bromide ion leads to the formation of organic and inorganic byproducts. Byproduct formation is influenced by bromide ion concentration, the source and concentration of organic precursors, pH, ozone dosage, temperature, and alkalinity. Both organic and inorganic byproducts increased when bromide ion concentration increased but decreased with an increase in alkalinity. Organic byproducts were found to increase with a decrease in pH, whereas bromate formation was favored by a high pH. In general, bromoform concentration first increased, then diminished, as the dosage of ozone was increased. Both ozonation and incubation temperatures had a positive effect on the formation of bromoform and bromate. PEROXONE appears to favor bromate formation over organic byproduct formation, whereas the addition of ammonia reduces both bromate and organic byproducts. Includes 22 references, table, figures.
