摘　　要：垃圾填埋场恶臭气体污染是填埋场作业和当地环境质量改善面临的重要问题之一。西安江村沟垃圾填埋场作为典型超大型填埋场,其恶臭污染物释放特征对于填埋场恶臭防治具有重要意义。通过对填埋场作业面、渗滤液暴露区以及渗滤液贮存池等主要恶臭源的典型恶臭污染物浓度进行监测,系统分析了不同季节恶臭污染物释放强度,并对恶臭气体进行了组分分析。结果表明:主要代表恶臭污染物(总挥发性有机物(TVOC)、H_(2)S和NH_(3))的浓度随着吹扫风速增加而降低,释放强度在四季的顺序为夏季>秋季>春季>冬季,夏季是恶臭预防控制的关键时期。相比填埋场作业面和渗滤液贮存池,渗滤液暴露区恶臭污染物释放强度最大。定量识别出苯系物、氯代烃、烯烃类、醇类、酯类等38种恶臭组分,氯苯类为主要污染因子,后期的填埋场恶臭控制应主要针对填埋场渗滤液苯系物进行控制。The odorous gas pollution produced by the landfill was one of the important problems faced by the landfill operation and the improvement of local environmental quality.Xi’an Jiangcungou landfill as the typical super large landfill,its odorous pollutant release characteristics are of great significance to the landfill’s odor control.By monitoring the typical odorous pollutant concentration of the main odorous sources such as the operation surface of the landfill,the leachate exposure area and the leachate storage tank,the odorous pollution release intensity of the sources in different seasons and the odorous gas composition was systematically analyzed.The results showed that the concentration of the main representative substances of odor(TVOC,H_(2)S and NH_(3))decreased with the increase of blowing wind speed.The release intensity in the four seasons was summer>autumn>spring>winter.Summer was the key period for odor prevention and control.Compared with the landfill operation area and the leachate storage tank,the leachate exposure area of the landfill had the strongest source of odor emission.38 kinds of odorous components,mainly including benzenes,chlorinated hydrocarbons,olefins,alcohols and esters were quantitatively identified.Chlorobenzenes were the main pollution factors.In the later stage,the odor control of the landfill should mainly focus on the control of benzene homologues in the landfill leachate.
