村镇供水中臭氧消毒副产物溴酸盐生成规律研究
Study on formation law of byproduct——bromate during ozone disinfection for rural drinking water supply
摘要
Abstract
In accordance with the characteristics of rural drinking water supply, the ozone adding experiment on the groundwater samples from 63 water sources for the rural drinking water in 9 provinces is made with three ozone dosing methods, and then the difference among the levels of bromate concentrations formed after the disinfections of the water samples from various areas is investigated and the impacts from both the ozone dosing and the dosing method on the bromate forming concentration are studied.The result shows that the less the bromonium ion concentration of the raw water is, the lower the pH value is to be, and then the less content of the bromate formed after ozone adding is to be as well, while the bromate formation shows linear positive correlation with the ozone dosage with a certain range.Under an identical dosing, the bromate formations corresponded to the three o-zone dosing methods, i.e.adding high concentration ozone water, adding by water-jet, direct adding of ozone gas, vary in an order from less to large.关键词
