北京生活垃圾臭气源特性分析

Characteristic Analysis of the Odor Source of Municipal Solid Waste in Beijing

＞从生活垃圾的来源、收集、运输以及处置四个阶段研究城市生活垃圾臭气产生源特征，检测生活垃圾臭气成分并分析其产生根源，为减量、控制和治理技术提供基础数据。试验表明：夏季NH，浓度调节池＞暴露源＞集气井＞土覆盖＞膜覆盖，而冬季的调节池＞暴露源＞土覆盖＞集气井＞膜覆盖，且调节池的NH，含量要远远高于其他监测点的含量；夏季和冬季共检出挥发性有机物163种，其中夏季检出127种，冬季97种，且夏天的臭气浓度远远高出冬季。

Odor emissions performance data had been collected from the process of collection, transportation and final disposal in order to analyze the source and characteristics of odor. The key odor basic data was used for reduction, prevention and comprehensive treatment technology. Results demonstrated that the concentration of NH3 in summer was adjusting pool〉source of the exposure〉wells for collecting gas〉layer covered with soil〉layer covered with membrane, while the concentration of NH3 in winter was adjusting pool〉source of the exposure〉layer covered with soil〉wells for collecting gas〉 layer covered with membrane, and the concentration of NH3 in adjusting pool was much higher than the other monitoring points. There were 163 kinds of volatile organic compounds detected in summer and winter including 127 species detected in summer and 97 in winter. What＇s more, the odor concentration of summer was far higher than that of winter.
