生物法处理挥发性有机废气(VOCs)的研究

生物法处理挥发性有机废气是近年来逐步发展起来的一项废气治理新技术，具有效率高、投资及运行费用低、无二次污染、安全性好等优点。文章主要概述了有机废气生物处理的3种主要形式：生物过滤池、生物滴滤塔和生物洗涤器的原理、流程以及研究进展，比较了以上3种反应器的优缺点，并提出了现存问题和将来的研究方向。

Study on Biological Treatment of Air Streams Contaminated with VOCs

Bio-treatment of volatile organic compounds（VOCs） is a newly-developed efficient technology. It differs from conventional methods, and has the advantages of simplicity, low operation and maintenance cost, easy management, no secondary pollution. The process and the principle and development of the biofiltcr, biotrickling filter and bioseubber which were three major types of bio-treatment of volatile organic compounds were summarized. The advantage and disadvantage of the former three bioreactors are discussed. Eventually, the trend of this technology was also discussed.
