生物除臭技术研究进展

Research Progress of Biological Deodorization Technology

生物除臭技术是一种应用前景广泛的除臭技术,它是利用有孔的、潮湿的介质上聚集的活性微生物的生命活动,将臭气中的H2S、NH3、有机溶剂等有害、发臭气体转变为简单的无机物,使之成为无害、无味气体,从而达到除臭的目的。阐述了生物除臭过程及传质机理,生物滤池及生物滴滤池的反应原理、优缺点及其应用。探讨了生物除臭技术存在的问题及今后的研究方向。

Biological deodorization technology is a kind of deodorization technology with broad application prospect, which makes use of activity of microorganism that gather on the poriferous and wet medium to change the smell of H2S, NH3, organic solvents and other harmful and smelly gases into simple inorganic substances to become harmless and tasteless gases, so as to achieve the purpose of deodorization. The paper expatiated on the process of biological deodorization and mechanism of mass transfer, the response principle of biofilter and biotrickling filters as well as their advantages, disadvantages and applications. It also discussed the problems existing in the biological deodorization technology and the future research directions.
