[目的 ]进一步了解 G市水源水及自来水有机污染物的种类及污染状况。 [方法 ]采集 G市两个水厂水源水及自来水 ,以 GDX树脂富集 ,气相色谱 -质谱 (GC/ MS)进行定性分析 ,气相色谱 -电子捕获检测器 (GC- ECD)进行定量分析。 [结果 ]水源水中共鉴定出 87种有机化合物 ,自来水中鉴定出 34种化合物 ,其中环状化合物 (含芳环 )占半数以上。 [结论 ]工业排污对水源水质影响大 ,水源位于下游工业区的有机污染较上游严重 ,经过处理的自来水仍含有多种毒害有机污染物。
[Objective] To understand more about the types and pollution status of organic pollutants in tap water and tap water in G city. [Method] The water and tap water of two waterworks in G city were collected and analyzed by GDX resin enrichment, gas chromatography-mass spectrometry (GC / MS) and gas chromatography-electron capture detector (GC-ECD) [Result] A total of 87 kinds of organic compounds were identified in water and 34 kinds of compounds were identified in tap water, among which cyclic compounds (including aromatic ring) accounted for more than half. [Conclusion] The industrial sewage has a great influence on the water quality of the source water. The organic pollution of the water source located in the downstream industrial zone is serious than that of the upper stream. The treated tap water still contains many toxic organic pollutants.
