摘　　要：臭氧氧化具有氧化能力强、反应速率快、对环境友好等特点,在水处理工艺中受到广泛关注。但臭氧在水处理中的应用存在利用率低、能源和运营成本高等问题。根据反应器的复杂程度以及规模扩大化应用,水动力传质技术是提高气液传质和臭氧氧化效率的重要手段,这已成为臭氧强化传质发展的趋势。文中阐述了传统反应器和微气泡反应器面临的问题,介绍了基于填料式反应器、振荡流反应器、气-液膜接触器、水动力空化等多种水动力传质技术在臭氧氧化水处理工艺的研究进展,并讨论了水动力传质技术在臭氧氧化工艺未来的发展方向以及待解决的问题。Ozonation is widely concerned in water treatment process because of the strong oxidation capacity,fast reaction rate and environmental friendliness.However,the application of ozone in water treatment has problems such as low utilization rate,high energy and operation costs.According to the complexity of the reactor and the scale up application,hydrodynamic mass transfer technology is an important means to improve gas-liquid mass transfer and ozonation efficiency,which has become the trend of ozone enhanced mass transfer development.In this paper,the problems concerning conventional reactors and microbubble reactors are described,the research progress of various hydrodynamic mass transfer technologies in ozonation water treatment process based on packed reactors,oscillatory flow reactors,gas-liquid membrane contactors,hydrodynamic cavitation,etc.are presented.Future directions of hydrodynamic mass transfer technologies in ozonation process and problems to be solved are discussed.
