The present study was aimed to quantitatively estimate the odor emission of municipal solid waste landfills in the loess area of Northwest China and investigate the technical feasibility of using loess soil as covering material for odor pollution control. For this purpose, the study was conducted in field and chose four types of landfill surface sources representing different periods and different coverage states in this region. The surface odor release rates were determined as follows: 5915µg/(m2·h) for newly formed landfill surface without cover, 122µg/(m2·h) for newly formed landfill surface with loess cover 757µg/(m2·h) for loess-covered surface after 5months, and 14057µg/(m2·h) for re-exposed landfill surface. The results indicated that the loess cover reduced odor emissions by more than 94% at two periods and effectively controlled various odor compounds. The analysis on the loess microbial community structure after 5 months of coverage showed that Actinobacteria had the highest relative abundance, potentially participated in the degradation of volatile organic compounds, and had a stronger effect on the surface. The experimental results demonstrated the effectiveness of loess cover in controlling odor emissions, proving that the application of loess as a landfill cover layer is feasible in the northwest region.
