摘　　要：采用粉末活性炭(PAC)/超滤联用工艺处理黄河原水,并利用气相色谱/质谱(GC/MS)分析技术考察了该工艺对有机污染物的去除情况。结果表明,黄河原水受有机污染较严重,共检出有机污染物71种,其中6种属于我国水环境优先控制污染物。超滤工艺可使水中有机物种类减少24种、色谱峰总面积降低54%;而PAC/超滤工艺可使水中有机物种类减少45种、色谱峰总面积降低91%。PAC/超滤联用工艺对有机物的去除能力明显优于超滤工艺,尤其对芳香烃类和杂环烃类有机物有很好的去除能力,能有效减轻黄河原水的有机污染,提高饮用水安全性。The combined process of uhrafihration and powdered activated carbon （PAC） was used to treat Yellow River raw water, and the removal effect of organic contaminants was evaluated by GC/MS analysis. The experimental results show that Yellow River raw water is seriously polluted by organic mat- ters. Seventy-one kinds of organic matters are detected, in which six kinds are specified as organic matters which should be controlled in priority mode in water environment in China. Twenty-four kinds of organic matters can be removed by uhrafiltration process, and the total peak area of organic matters is decreased by 54%. The combined process of uhrafihration and PAC can remove forty-five kinds of organic matters and decrease 91% of the total peak area of organic matters. As a conclusion, the combined process of ultrafihration and PAC can remove organic contaminants, specially aromatic hydrocarbons and heterocyclie hydrocarbons, more effectively than ultrafihration and enhance the security of drinking water from Yellow River.
