目的:了解宁夏银川市城区水源水、出厂水及末梢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:水中有机污染物采用XAD-2树脂富集,GC/MS分析测定。结果:检出银川市某水源水、出厂水及末梢水均含有微量有机污染物。水源水中以苯系物,直链烷烃和多环芳烃等为主;出厂水中以酮类、邻苯二甲酸酯类、直链烷烃为主;末梢水中含有氯代化合物、直链烃,邻苯二甲酸酯类及芳烃等有机化合物。结论:银川市饮用水及水源水均已受到有机物的污染。对不同水体优先监测、优先管理、优先控制的污染物亦应有所区别。因此建议各个水厂应加强管理,采取饮用水深度处理技术,生产出更加优质的饮用水。
Objective: To understand the pollution status of organic pollutants in the water source, factory water and peripheral water of Yinchuan City in Ningxia, and provide a scientific basis for supervision and management. Methods: The organic pollutants in water were enriched by XAD-2 resin and analyzed by GC / MS. Results: Yinchuan City, a source water was detected, the factory water and peripheral water contain traces of organic pollutants. Mainly water, benzene, linear paraffins and PAHs, etc .; in the factory water to ketones, phthalates, straight paraffins based; peripheral water containing chlorinated compounds, straight chain hydrocarbons, o-benzene Dicarboxylic acid esters and aromatic compounds such as organic compounds. Conclusion: Yinchuan City, drinking water and water sources have been contaminated by organic matter. Priority should be given to the monitoring of different waters, priority management, and priority control of pollutants should also be different. Therefore, it is suggested that all waterworks should strengthen management and adopt advanced drinking water treatment technology to produce more high-quality drinking water.
