畜禽场恶臭VOCs的产生及防控技术进展

PROGRESS IN GENERATION,PREVENTION AND CONTROL OF ODOROUS VOCs FROM LIVESTOCK AND POULTRY FARMS

规模化、集约化畜禽场排放的恶臭挥发性有机物(VOCs)是大气中恶臭气体污染物的重要组成部分,其臭阈值较低,对畜禽场实际臭气贡献较大,危害人类和动物的身心健康以及周边居民的生活环境。重点介绍了畜禽场恶臭VOCs的主要成分、产生机制和危害,并系统论述了畜禽场恶臭VOCs源头减排和末端处理防控技术的现状和研究进展,总结了先进减排技术VOCs的降解效率等相关实验结果。

Odorous volatile organic compounds(VOCs)from large-scale livestock and poultry farms,characterized by low olfactory threshold,are the important parts of the odorous gas pollutants.The odour nuisance is associated with danger and may be the cause of negative psychosomatic symptoms of humans and animals,as well as the environment.The objective of this article was to introduce the production mechanism and harm of main odorous VOCs,and to provide a systematic review on the research progress of source reduction and end treatment technologies for odorous VOCs,as well as to summarize available data on VOCs reduction effectiveness of promising technologies.
