| 摘 要： | 采用吹扫捕集-GC／MS法对浙江省某工业园区污水处理厂中残留的难降解物质进行了定性和半定量分析，分析结果有9个响应值较高的峰，通过NIST库检索，得到这9个物质在水中残留的浓度高低依次是二氯甲烷最高，其次是四氢呋喃、三氯甲烷、1，4-二氯苯、1，2-二氯乙烷、二甲氧基甲烷、五氯环丙烷、1，4-二氯-2-氟苯、N，N-二甲基苯胺。并从这几种物质的性质、用途和这个工业园区生产企业生产的产品，分析了这几种物质在这个工业园区污水中残留的原因及危害，同时提出去除这些残留物质的方法。

| Abstract: | This study conducted qualitative and semi - quantitative analysis on refractory pollutants from an urban sewage treatment plant in Zhejiang Province by purge and trap - GC/MS. The results show that there are nine obvious peaks. According to NIST databank, residual concentration of the nine substances in a descending order is methylene chloride, furan tetrahydro, tri- chloromethane, benzene 1,4 - dichloro, ethane 1,2 - dichloro, methane dimethoxy, cyclopropane pentachloro, 1,4 - dichloro - 2 - fluorobenzene and N, N - dimethyl aniline. This paper analyzed the causes and dangers of these residual compounds from the properties, application and the products produced by enterprises in the industry district. Some suggestions on removing these pollutions were put forward. |
