摘　　要：选取垃圾填埋场恶臭气体中的H2S和NH3作为评价指标,对填埋库区和渗沥液调节池进行气体采样并测量H2S、NH3的浓度变化,分析逆温效应、大气温度、降雨以及覆土等因素对臭气浓度的影响。结果表明:H2S和NH3排放浓度均受逆温效应影响严重,并有明显的季节变化,呈春、夏季高而秋、冬季低的特征。此外,降雨和覆土可以显著降低填埋场恶臭污染物的排放浓度。The influences of temperature inversion effect, atmospheric temperature, rainfall and soil covering on odor emission in waste landfill sites were analyzed. H2S and NH3 were chosen as the main evaluation index, and their concentration in both the landfill area and leachate regulating tank were sampled and measured. The results indicated that the emission of H2S and NH3 was strongly relevant to temperature inversion effect. The emission concentration also varied with the variation of seasons, higher in spring and summer, lower in autumn and winter. In addition, it is also found that the rainfall and soil covering can dramatically reduce the odor emission in landfill site.
