摘　　要：为研究垃圾转运、焚烧处理设施挥发性有机污染物排放现状,采用GC-MS(气相色谱质谱联用仪)方法分析了垃圾处理设施不同采样点臭气中物质组成及主要组分含量。在所采集的样品中定量分析了111种物质,从中筛选21种物质并根据其归一化浓度建立了各采样点的指纹谱图。结合物质嗅阈值和指纹谱分析,初步识别了不同处理设施采样点的典型恶臭污染物,其中垃圾转运站站内包括对二甲苯、间二甲苯、邻二甲苯、二甲基二硫醚,站外包括甲苯、乙苯、二硫化碳、甲硫醇;垃圾焚烧厂渣坑为甲硫醚,渗滤液为硫化氢。The paper is aimed to present the investigation results of the fingerprint spectrum of the odor pollutant from the garbage transfer station and garbage incineration plant with the GC-MS method in hoping to find the main constituents and levels of odor pollutant from the said two types of garbage disposal installation in Tianjin. A total of 111 compounds in the samples have been quantitatively analyzed,of which 21 typical compounds have been selected to construct the fingerprint spectrum of odor pollutant from the garbage transfer station and garbage incineration plant.Among them,we have managed to have sorted out and identified the typical pollutants in various sampling units based on the olfactory threshold and fingerprint spectrum,which can be stated in the following way： p-xylene,m-xylene,o-xylene,dimethyl disulfide inside the garbage transfer station, and toluene, ethylbenzene,carbon disulfide and methanethiol outside the garbage transfer station; methyl sulfide for slag pit and hydrogen sulfide for leachate in the garbage incineration plant. Among them,what US EPA is predominantly concerned about may include mononuclear aromatic and halohydrocarbon. Moreover,among the 25 primarily concerned pollutants,we are mainly concerned about 18 ones from the garbage transfer station and 25 ones from the garbage incineration plant. From example,we have found that the concentration of pollutants inside the station proves to be higher than that outside of it. Say,the concentration of aromatic hydrocarbons inside the station proves 39. 48 whereas it is only 8. 58 outside of the station. On the other hand,while the concentration of sulfide in the station turns to be 2. 95,it turns to be only 2. 72 outside of the station. As to the oxygenated compounds,it proves so low that it can only be detected along with ethanol and acetone. Hydrogen sulfide concentration that can be found in the leachate of the waste plant tends to be merely 8 304. 78,with that of aromatic hydrocarbons remaining between 0. 37 and 0. 82.And,so low can
