摘　　要：生物技术作为挥发性有机物(VOCs)的处理技术之一,具有高效、操作简单、运行费用低和无二次污染等技术特点。然而,疏水性VOCs水溶性差,传统生物处理过程中存在气液相传质速率低、VOCs可生物降解性差和微生物降解能力差等问题。本文针对疏水性VOCs处理生物技术中存在的问题,介绍了生物组合技术和生物强化技术,并分析了提高技术处理性能的方法和过程机理,总结了现有技术的处理效果,最后对生物组合技术和生物强化技术处理疏水性VOCs的应用进行了展望。Biotechnology is one of the treatment technologies of volatile organic compounds(VOCs).It has the technical characteristics of high efficiency,simple operation,low operating cost,and no secondary pollution.However,hydrophobic VOCs have poor solubleness,and conventional biotreatment faces a low mass transfer rate from the gas phase to the liquid phase,poor biodegradability of VOCs,and insufficient ability to biodegrade microorganisms.Therefore,this study reviewed the problems of hydrophobic VOCs in biotechnology and introduced biocombination and bioaugmentation technologies.It also analyzed the method and process mechanism of improving the treatment performance of the technologies and summarized the treatment effect of the existing technologies.Finally,the application of biocombination and bioaugmentation technologies in the treatment of hydrophobic VOCs was prospected.
