丝状真菌生物过滤塔对挥发性有机物的去除性能

Performance of Filamentous Fungal Biofilters for Volatile Organic Compounds Control

生物过滤塔工艺是控制挥发性有机物(VOCs)污染的一种重要工艺。其中,丝状真菌由于所产生的菌丝体易捕捉气相中的疏水性污染物,同时又具备耐受低pH值和适应干燥环境等特性,而日益成为VOCs生物过滤技术中新的研究热点。文章在对丝状真菌生物过滤塔的降解机理和特点进行分析的基础上,针对目前在生物过滤塔技术中研究较多的几种典型丝状真菌,较详细介绍了该类真菌生物过滤塔对VOCs的去除性能,并对该技术在VOCs控制方面的研究与应用中存在的问题和发展方向进行了分析和展望。

Gas phase biofilters are widely accepted as a new technology for the volatile organic compounds （VOCs） treatment, and filamentous fungal biofilters are becoming the focus of this kind of technology because of advantages of being more resistant to reduced moisture content and low pH. Mechanism and main characteristics of filamentous fungal biofilters are described as well as the performances of different filamentous fungal biofilters for VOCs control. Problems and prospects of the filamentous fungal biofiltration technology are also analyzed.
