中文摘要：

总结了不同区域、不同时段生活垃圾的恶臭特性，发现恶臭特性受垃圾组分、处理处置工艺等因素影响较大，垃圾中转站的主要恶臭组分为乙酸乙酯、甲苯、乙苯等挥发性有机物（VOCs）及氨气，填埋场恶臭组分中含硫化合物和含氧化合物浓度高，堆肥场恶臭组分中苯系物和烃类浓度较高，焚烧厂恶臭组分主要为苯系物。基于复杂多变的生活垃圾恶臭特性，采用综合评分法评价恶臭的环境影响程度，对已报道的生活垃圾恶臭组分进行综合评价，发现生活垃圾降解过程释放的恶臭组分中，二甲二硫、硫化氢、甲硫醇、萘、1，3，5三甲苯、甲硫醚、甲苯、乙苯、对二甲苯和α-蒎烯等是混合生活垃圾优先控制的恶臭污染物。

英文摘要：

The odor properties from different stages in waste sector were reviewed,and the relationship between odor components and the operation stage, the locations as well as the waste components were summarized. The domi nant odorants components in waste transfer station were ethyl acetate, methylbenzene, ethylbenzene and ammonia. The concentration of oxygenated compounds and sulfo-compounds was relative high in odor emission from landfill. In composting site,the main odorants components were benzene series and hydrocarbons, and in waste incinerator, the dominant odorants were benzene series. Besides,a comprehensive evaluation on the prior odorant was compared based on the waste characteristics, and 10 typical odorants were screened, including dimethyl disulfide, hydrogen sulfide, methyl mercaptan, naphthalene, 1,3,5-trimethyl benzene, dimethyl sulfide, methylbenzene, ethylbenzene, p-xylene, α-pinene,all of them should be priority considered on the odor control process.
