生物除臭技术在畜禽场臭气处理中的应用研究进展

Research Progress on the Application of Biological Deodorization Technology in the Treatment of Odor in Livestock and Poultry Farms

集约化畜禽场的臭气排放对环境和人类健康的危害引发越来越多的关注。臭气处理的方法有多种,其中生物法因其低成本、除臭效率高的优势得到了更为广泛的应用。在综述不同生物除臭技术原理的基础上,对影响除臭性能的主要因素(填料、pH、营养、温度、微生物)进行分析。总结新型生物除臭设备及技术的研究进展,并对今后生物除臭的发展趋势进行展望。

The harm of odor emissions from intensive livestock and poultry farms to the environment and human health has attracted increasing attention.There are various methods for odor treatment,among which the biological method has been more widely used due to its advantages of low cost and high deodorization efficiency.Based on the review of the principles of different biological deodorization technologies,the main factors affecting deodorization performance(fillers,pH,nutrients,temperature,microorganisms)were reviewed.This study summarizes the research progress of new biological deodorization equipment and technologies,and prospects the development trend of biological deodorization in the future.
