臭氧氧化水库原水溴酸盐生成的控制研究

摘要

探究了棘洪滩水库原水经臭氧氧化后,消毒副产物溴酸盐的生成情况.通过混凝改变进水水质,探究了不同水质条件下溴酸盐生成量的差异,证明有机物含量越低溴酸盐生成风险越大;投加过氧化氢可以有效抑制溴酸盐的生成;在臭氧工艺后增添活性炭工艺可以有效去除臭氧工艺产生的溴酸盐.%The formation condition of disinfection by-product bromate in ozonation process of Jihongtan Reservoir raw water was explored.The inflow water quality was changed by coagulation.Difference in formation amount of bromate under different water quality conditions was discussed,which showed that lower organic matter content,higher risk of bromate formation.The addition of H2O2 efficiently inhibited bromate formation.After ozonation process,the addition of activated carbon could efficiently remove bromate produced by ozonation process.
