【摘要】：目的分析上海市黄浦区生活饮用水中氯化消毒副产物(CDBPs)的污染水平和分布特征,同时研究氯化消毒副产物产生的影响因素。方法选取辖区内出厂水、管网水、二次供水等供水情况进行调查,同时对主要的氯化消毒副产物以及天然有机物、总氯等指标进行检测。结果水体中含量总体分布为三氯甲烷二氯一溴甲烷一氯二溴甲烷三溴甲烷;其水体中含量总体分布为二氯乙酸三氯乙酸;一氯二溴甲烷、三溴甲烷、二氯乙酸的浓度丰水期和枯水期比较,其差异有统计学意义(P0.05),丰水期含量高于枯水期;饮水中二溴一氯甲烷、三溴甲烷、三氯乙酸浓度与总有机碳含量呈正相关,Pearson相关系数分别为0.383、0.564、0.340(P0.05)。结论在该区饮用水中氯化消毒副产物有较高的检出率,丰水期含量高于枯水期。总有机碳是氯化消毒副产物形成的影响因素。
[Abstract]:Objective to analyze the pollution level and distribution characteristics of chlorinated disinfection by-products (CDBPs) in drinking water in Huangpu District of Shanghai, and to study the influencing factors of disinfection by-products. Methods we investigated the water supply situation of factory water, pipe network water and the two water supply, and detected the main chlorinated disinfection by-products, natural organic matter and total chlorine. The water content in the overall distribution of chloroform two chloro methyl bromide dibromochloromethane three methyl bromide; the water content in the overall distribution of three chloroacetic acid two chloroacetic acid; two chloroacetic acid dibromochloromethane, three methyl bromide, the concentration of the wet period and dry season, the difference was statistically significant (P0.05), the wet period was higher than that in the dry season; drinking water was positively dibromochloromethane and three methyl bromide, three trichloroacetic acid concentration and total organic carbon content, the Pearson correlation coefficients were 0.383, 0.564, 0.340 (P0.05). Conclusion there is a high detection rate of the chlorinated disinfection by-products in the drinking water in the area, and the content of the water in the season is higher than that in the dry period. Total organic carbon (total organic carbon) is an influential factor in the formation of chlorinated disinfection by-products.
