| 摘 要： | 恶臭污染已成为生活垃圾堆肥过程中的主要环境问题.以大类粗分后的厨余垃圾作为研究对象,利用嗅觉测定法和GC-MS分析了不同阶段堆肥尾气的臭气浓度和恶臭化合物的种类及其排放浓度,并对不同堆肥阶段臭气浓度和恶臭物质排放浓度的相关性进行分析.结果表明,厨余垃圾堆肥过程中共检测到43种挥发性有机物,其中含硫臭气物质5种,烃类化合物22种,芳香烃类化合物11种,其它物质5种.通过相关性分析,发现硫化氢、甲硫醇、1,3-二甲基苯和邻二甲苯与臭气浓度极显著相关(P<0.01),二甲二硫和对二甲苯与臭气浓度显著相关(P<0.05),因此在厨余垃圾堆肥过程中要对这6种臭气物质进行重点监测和控制.

| Abstract: | Odor pollution has become a major environmental problem in municipal solid waste composting. The odor samples at different composting phases of kitchen waste were collected and analyzed by olfactometry and gas chromatography-mass spectrometry (GC-MS). The correlation between the odor concentration and the emission of odor compounds was also analyzed.The results showed that there were 43 kinds of volatile organic compounds (VOCs) in the composting process of kitchen waste, including 5 kinds of sulfur odor compounds, 22 kinds of hydrocarbon compounds, 11 kinds of aromatic compounds and 5 kinds of other odor compounds. The correlation analysis indicated that the odor concentration was very significantly correlated with the emission of hydrogen sulfide, methanethiol, 1,3-xylene and o-xylene (P<0.01), and significantly correlated with the emission of dimethyl disulfide and p-xylene (P<0.05). Therefore, those 6 kinds of odor compounds should be intensively monitored and controlled during the composting process of kitchen waste. |
