通过对北京市阿苏卫生活垃圾卫生填埋场合硫恶臭排放源研究,结果表明垃圾无组织源头排放二硫化碳浓度最高为11.18 mg/m3,其次为二乙硫醚、二甲硫醚和硫化氢,硫化氢浓度随着距离增大而减小,200 m以后衰减完毕.垃圾填埋场有组织排放源中,硫化氢气体浓度介于4.23～69.09 mg/m3.根据EPA-LandGEM一阶降解速率方程式可准确界定恶臭气体污染源强.%Researches on sulfur malodor emission sources in Asuwei Domestic Waste Sanitary Landfill Site of Beijing were carried out. The results showed that the unorganized waste is the source of the highest concentration of carbon disulfide emissions (11. 18 mg/m3), followed by diethyl sulfide, dimethyl sulfide and hydrogen sulfide. Hydrogen sulfide concentration in general decreased with distance increasing. When the distance is 200 m, the hydrogen sulfide concentration decay is completed. Hydrogen sulfide concentrations were 4.23-69. 09 mg/m3 in organized sources of waste landfill sites. According to EPA-LandGEM first order degradation rate equation, pollution intensity of odor sources was accurately defined.
