两相分配生物反应器处理有机废气新技术

摘要

The treatment of waste gas containing volatile organic compounds(VOCs) using two-phase partitioning bioreactor in recent years was reviewed.The common bioreactors(including the stirred tank bioreactor,the biotrickling filter,and the biofilter,etc.) and VOCs removal effect were introduced in details.The advantages and disadvantages of the non-aqueous phases(silicone oil,hexadecane,and tetradecane,etc.) in the application for the removal of VOCs using two-phase partitioning bioreactors were discussed.The mass transfer mechanism of the organic pollutants in the two-phase partitioning bioreactor was also discussed.The development prospect and the improvement direction for the two-phase partitioning bioreactors were analyzed.%综述了近期国内外有关两相分配生物反应器处理有机废气技术的研究进展.介绍了搅拌釜生物反应器、生物滴滤塔、生物滤床等多种反应器结构及其去除有机废气的效果；分析了硅油、十六烷、十四烷等多种非水相介质在两相分配生物反应器中应用的优缺点；阐述了有机废气在两相分配生物反应器中的传质机理.最后对两相分配生物反应器的发展前景及改进方向进行了分析.
