| 摘 要： | 采用固相萃取(SPE)样品富集前处理技术和气相色谱/质联联用(GC/MS)分析方法,对北方某工业城市给水系统中的多环芳烃类化合物的含量水平进行了研究.结果表明,该城市多环芳烃污染水平较高,但总浓度均未超过城市供水水质标准(CJ/T206-2005)中限值(2μg/L).近郊水库由于受到燃料燃烧产生的多环芳烃的污染,成为该市饮用水中多环芳烃污染的主要来源.传统的混凝-砂滤工艺对多环芳烃有较好的去除效果,总去除率可达55.9%. |

| Abstract: | Water samples were collected from the water supply systems of an industrial city of north China.Polycyclic aromatic hydrocarbons(PAHs) residues were assessed by solid phase extraction combined with GC/MS analysis.The results showed that although the PAH concentrations are relative higher than other cities,they do not exceed the relative limit of urban water supply standards(CJ/T206-2005).The nearer reservoir is polluted by the PAHs from combustion and becomes the main pollution source.The total removal efficiency for PAHs of conventional oagulate-sand filtration treatment process is 55.9%. |
| Keywords: | polycyclic aromatic hydrocarbons source water pollution of water distribution system processes of water treatment |
