摘　　要：随着城市化进程的加剧,填埋场恶臭逐渐成为影响城市生活的重要污染.对于场界范围内的恶臭发生源通常要依靠经验确定,难以对填埋场界范围内的恶臭污染强度分布及变化规律进行科学的描述.利用电子鼻与GPS定位仪对生活垃圾填埋场内的恶臭污染情况进行检测,通过GIS软件作图绘制恶臭污染等强度曲线,对场内强污染源释放点进行确定,发现覆盖膜破损及焚烧火炬尾气排放是造成场内恶臭污染的主要原因.对填埋气产量估算分析表明提高填埋气处理能力是控制恶臭污染的关键.Odor pollution of landfill site is a serious problem accompanied with the urbanization process that influences city life. Generally, odor emission points in landfill boundary are detected by experience, but the pollution intensity, distribution and variation in the scope of landfill boundary are difficulty to describe. In this research, odor emission points were disclosed with equal odor concentration curves that were delineated using electric nose and GPS instrument. The leakage of landfill gas and exhaust emission from biogas incineration torch was the main cause of the odor pollution in landfill area. Gas production evaluation suggested that the improvement of landfill gas consumption is the key point to control the odor pollution at the landfill site.
