摘　　要：为研究含溴原水深度处理中溴酸盐生成的影响因素,对苏州地区X水厂原水,各工艺段的出水,以及出厂水中的溴酸盐、溴化物、氨氮、高锰酸盐指数等水质指标进行了检测,并考察了各类水质指标与出厂水溴酸盐含量之间的关系。结果表明X水厂深度处理工艺过程中,溴酸盐浓度的峰值出现在主臭氧后,随着臭氧投加量的增加或者原水氨氮浓度的降低,出厂水中溴酸盐浓度呈增加的趋势;出厂水中溴酸盐浓度与原水中溴化物浓度有非常显著关系,其回归方程相关系数达到0.7133;原水高锰酸盐指数和出厂水溴酸盐之间回归方程的相关系数达到了0.4898。To study the influencing factors of bromate＇s generation in advanced treatment with raw water containing bromide,several water quality index of raw water,process water and finished water produced by X waterplant in Suzhou was investigated,including bromate,bromide,ammonia nitrogen and permanganate index.The relationship between the quality index and bromate was also investigated.The results shows that in process of advanced treatment by X waterplant,the peak value of bromate appears after the main ozonation process and the concentration of bromate is enhanced by the increasing of ozone dosage and the decreasing of ammonia nitrogen in raw water.The concentration of bromate in finished water is mainly effected by the bromide in raw water.The correlation coefficient of regression equation between bromate and bromide reaches 0.713 3.The correlation coefficient of regression equation between bromide in finished water and permanganate index in raw water reaches 0.489 8.
