摘　　要：目的:研究源水中有机物污染对饮用水中氯化消毒副产物形成的影响。方法:采用安捷伦7890A气相色谱仪、ECD检测器,对自贡市36家自来水厂出厂水管网末梢水中的三卤甲烷、卤乙酸、高锰酸钾耗氧量进行测定。结果:36家自来水厂的出厂水管网末梢水不同程度检出氯化消毒副产物三卤甲烷(三氯甲烷、二氯一溴甲烷、一氯二溴甲烷、三溴甲烷),卤乙酸(二氯乙酸、三氯乙酸)。结论:水源水种类、有机物污染是影响消毒副产物生成的因素,江河水、耗氧量高的源水消毒副产物较多。Objective： To discuss the influence of organic pollutants in source water on the formation of chlorinated disinfection byproducts in drinking water. Methods：Trihalomethanes, haloacetic acids and potassium permanganate oxygen consumption in finished water and peripheral water of the 36 waterworks in Zigong were determined by gas chromatograph and colorimeter. Results：The disinfection byproducts were detected in defferent degrees in all of the 36 waterworks. Conclusion： The influencing factors of disinfection byproducts in water were consisted of the type of source water and organic pollution, the disinfection byproducts increased in the water of river and the source water with high oxygen consumption.
