摘　　要：以亲疏水性为切入点,针对含多组分挥发性有机物(volatile organic compounds,VOCs)的工业废气,综述了生物滴滤床技术(biotrickling filters,BTFs)的研究现状与发展趋势。重点围绕多组分VOCs之间的拮抗作用、协同作用、交互作用,总结与剖析了三大作用的研究现状与成因,从BTFs内气液/固两相传质和生物降解动力学模型入手,阐述了BTFs中VOCs的传质和生物转化过程及其相互作用机制。展望了BTFs适应当前市场需求的应用化发展前景,提出以削弱或抑制拮抗作用、构建和强化协同作用体系为研究方向,通过强化对共代谢和增溶等作用机制的理论认知,构建具有协同效应的VOCs处理体系,进而推动BTFs的理论发展和应用推广。Taking the hydrophilicity and hydrophobicity as the starting point,the research status and development trend of biotrickling filters(BTFs)for industrial waste gas containing multi-component volatile organic compounds(VOCs)are summarized.This paper focuses on antagonistic,synergistic,and mutual effects among multiple VOCs,which summarizes and analyzes the immanent cause leading to the interactions.Besides,the gas-liquid/solid twophase mass transfer models and biodegradation kinetics models are used to elaborate the VOCs mass transfer and biotransformation processes and their mechanisms in BTFs.Furthermore,application prospect is prospected to satisfy to current market requirement through construction and strengthening of synergistic effect instead of antagonism.And the treatment systems of VOCs are constructed by strengthening theoretical cognition of cometabolism and solubilization mechanisms,which would promote BTFs developments in two aspects of theory and application.
