| 摘 要： | 以某市三个水库水源水为研究对象,采用组合树脂XAD4/8吸附、浓缩以及色谱–质谱(GC-MS)联机定性分析技术,研究了三个水库中微量有机物的种类、组成及沿程空间分布特性。结果表明在酸性富集条件下,在A水库的水中检测出的有机物种类最多,为13种,主要以苯系物为主;在C水库的水中有机物种类次之,为12种,主要以长链烷烃为主;在B水库有机物种类最少,为7种,主要为苯系物及长链烷烃。总出峰面积沿程递增(A、B、C),结合三个水库的CODMn、BOD5及NH4+-N情况,说明三个水库污染程度由轻到重的顺序为A水库,B水库,C水库,位于下游的B、C水库较上游受污染程度严重。 |

| Abstract: | In this paper,water samples of three reservoirs as drinking water source were studied in certain city using synthesized resin XAD4/8 concentrating and gas-chromatography-mass spectrometry(GC-MS) system qualitative analysis.The results indicate that under acidic concentration condition,organic pollutants level is the highest which is mainly composed of long-chain in reservoir C.The organic pollutants level is in the second place which is mainly composed of benzene and long-chain alkane in reservoir B.The principal composition of reservoir A is benzene.Based on the CODMn,BOD5 and NH4+-N,the sequence of the pollution from light level to serious level is reservoir A,reservoir B,reservoir C.The reservoirs located in downstream are polluted more severe than upstream. |
