摘　　要：目的了解昆明市2015年-2016年生活饮用水氯化消毒副产物的主要污染情况,为各自来水厂的日常管理、监测提供依据。方法按照《生活饮用水标准检验方法》(GB/T 5750—2006)采用气相色谱仪、分光光度计、余氯比色计对昆明市7个水厂出厂水4个季度包括三卤甲烷和卤乙酸在内的12种消毒副产物进行监测分析。结果 2015年第4季度-2016年第3季度各水厂消毒剂副产物指标,检出项目主要有三氯甲烷、一氯二溴甲烷、二氯一溴甲烷、二氯乙酸、三氯乙酸、三氯乙醛及余氯,三卤甲烷中三氯甲烷所占比重较大,三氯乙醛及2种卤乙酸各季度均有检出且含量相对偏高,而其他项目均为未检出。结论昆明市饮用水中消毒副产物污染情况较轻,7个水厂出厂水在4个季度内氯化消毒副产物指标符合《生活饮用水卫生标准》(GB 5749—2006)的要求。Objective To investigate the main pollution status of chlorinated disinfection by-products in drinking water in Kunming from 2015 to 2016,so as to provide basis for daily management and monitoring of waterworks.Methods According to Standard Examination Methods for Drinking Water(GB/T 5750—2006),the 12 disinfection by-products including trihalomethanes and haloacetic acids in Kunming drinking water were analyzed by gas chromatograph spectrophotography and chlorine colorimeter.Results Chloroform,dibromochloromethane,bromodichloromethane,dichloroacetic acid,trichloroacetic acid,trichloroaldehyde and residual chlorine are mainly disinfection by-products;trichloromethane accounted for a large proportion of trihalomethane;trichloroacetaldehyde and two haloacetic acids were detected in each quarter and the content was relatively high;other projects are not detected.Conclusion The pollution of disinfection by-products in drinking water in Kunming is relatively low,and the disinfection by-products in four quarters are qualified.
