中文摘要：

采用GC-MS联用技术对深圳市两个垃圾填埋场（A和B）渗滤液中的有机污染物进行分析。垃圾场A是简易生活垃圾填埋场，垃圾场B是生活垃圾焚烧底渣填埋场。垃圾场A渗滤液中COD、TOC、NH3-N、NO3^--N等污染指标的浓度比垃圾场B渗滤液高一个数量级。两个垃圾填埋场渗滤液中分别检测出主要有机物72种和57种，其中含有大量难降解有机物，如酚类、胺类、杂环类物质。两个垃圾填埋场渗滤液中有机物组分的相对含量不同，渗滤液A中酚类物质含量最高，渗滤液B中有机物多为长链烷烃。

英文摘要：

The organic pollutants in leachates from two municipal landfins （A and B） were determined by GC-MS. Landfin A is a simple municipal solid waste landfin, and landfin B is mainly disposed of bottom ashes from a MSW incineration plant. The leachate of landfin A has nearly one order of magnitude higher concentrations of COD, TOC, NH3-N, NO3^- -N than those of landfin B. 72 and 57 kinds of main organic pollutants were identified in leachates from landfin A and B, respectively. Among the organic chemicals, organic compounds which are difficultly degraded, including phenols, aliphatic amides and heteroeylic compounds were determined, The relative distributions of chemical groups of substances in leachates of landfills A and B are different, The leachate of landfin A has organic components dominated by phenols, while the principal chemicals are long-chain alkanes in leachate B.
