摘　　要：目的了解宁夏中卫市城区饮用水中有机污染物的污染状况,为监督管理提供科学依据。方法饮用水中有机污染物采用XAD-2树脂富集,GC/MS分析测定。结果共检出有机污染物44种,其中以氯代化合物、邻苯二甲酸酯类、醇类、杂环类、芳烃及直链烃为主,并且有4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、1,4-二甲基苯。结论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。OBJECTIVE To learn the organic pollutants of drinking-water in Zhongwei of Ningxia and to provide scientific basis for supervision and management. METHODS The organic pollutants in drinking water were concentrated on XAD-2 resins and analyzed by GC-MS. RESULTS 44 kinds of organic pollutants in water samples, mainly chlorides, phthalateesters, alcohols, heterocyclic compounds and aromatic hydrocarbons were detected. Among these pollutants, there were trichloroethylene, naph- thalene, DBP, and 1, 4-dimethyl benzene, which were listed as top 4 pollutants in environment in China. CONCLUSION 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.
