摘　　要：生物法处理挥发性有机化合物(VOCs)具有反应条件温和、运行费用低,二次污染小等优点。文章综述了生物过滤、生物滴滤、生物洗涤、膜生物反应器等4种净化工艺;总结了前人就废气性质、降解菌、填料结构与特性、pH与温度等因素对反应体系降解性能的影响;综述了研究废气生物降解过程和研究生物量积累与运行性能关系等的动力学模型。最后论述了该技术当前存在的问题和发展趋势。Biopurification of volatile organic compounds （VOCs）has advantages of mild reaction conditions and low operating costs, as well as few undesirable byproducts. Several bioreactors including biofilters, biotrickling filters, bioscrubber and membrane bioreactor were reviewed. Effects of VOCs characteristics, bacteria, structure and characteristics of packing materials, pH and temperature on bioreactor performance were reviewed. Many numerical models developed to predict biodegradation process and bioreactor performance were also reviewed and discussed. Current problems and trends of biopurification were predicted and discussed as well.
