英文摘要: Municipal solid waste landfills are one of the major sources of odor complaints. The determination of volatile compounds (VCs) emissions and their rates is a necessary prerequisite to calculate and study VCs dispersion and control. In this study a wind tunnel system has been introduced to investigate the VCs emission rates from the working face of a large anaerobic landfill in China. The VCs in gas samples were characterized by gas-chromatograph-mass-spectrometer. The emission rates of VCs increased linearly with sweeping velocity (0.1m·s-1 to 0.5m·s-1), and 0.28m·s-1 was selected as the recommended practical operation sweeping velocity. The VCs emission rates on the working face at the landfill site were investigated during the course of a day. 31 chemical species divided into six chemical groups were quantified with the following emission rates: oxygenated compounds: 205.73-750.00μg·m-2·s-1, hydrocarbons: 61.82-220.37μg·m-2·s-1, aromatics: 15.55-40.11μg·m-2·s-1, halogenated compounds: 11.71-31.57μg·m-2·s-1, terpenes: 2.71-18.70μg·m-2·s-1, and sulfur compounds: 1.29-10.84μg·m-2·s-1. The highest average emission rates of VCs were found from midnight to dawn (1:00-7:00). These results provide key input parameters to users of VCs dispersion models to calculate buffer distances. © 2015 Elsevier Ltd. Citation statistics:
