摘　　要： 采用XAD树脂富集技术和GC/MS方法,对长沙市某管网末梢水中的微量、痕量有机污染物进行分析,共检出有机污染物38种,其中以氯代化合物、邻苯二甲酸酯类、醇类、杂环类、芳烃为主,并且有5种物质在中国环境优先污染物"黑名单"之列,分别是三氯乙烯、萘、邻苯二甲酸二丁酯、乙苯、1,4-二甲基苯.由于常规水处理工艺无法去除这些对人体有害的物质,因此建议水厂在考虑自身条件的基础上,积极采用活性炭吸附、臭氧氧化以及膜分离等饮用水深度处理技术,生产出更加优质的饮用水. In this study, the trace organic pollutants of drinking water in Changsha city were concentrated on XAD resins, then the concentrate was analyzed with GC/MS. It indicated that there were 38 kinds of organic pollutants in water samples, mainly chlorides, phthalate esters, alcohols, heterocyclic compounds and aromatic hydrocarbons. And trichloroethylene, naphthalene, DBP, ethylbenzene and 1,4-dimethylbenzene are listed as top pollutants of environment in China. As conventional processes of water treatment can not remove the harmful pollutants from water resources, advanced techniques of water treatment, such as active carbon adsorption, ozonation and membrane separation, are recommended to water plants for high-quality drinking water.
