摘　　要：臭氧高级氧化法具有高效、无二次污染等优势,广泛用于各类废水处理,而臭氧在气液界面传质效率低增加了运行成本.依据臭氧传质理论,从改进气液两相接触器结构、加入促传剂、外场强化等方面综述了臭氧传质的研究现状及强化机理,并展望了强化臭氧传质的发展方向.Ozonation technology has the advantages of high efficiency and no secondary pollution, which has been widely used in a wide array of wastewater treatment. However, the low efficiency of ozone mass transfer in the gas-liquid interface increases the operating cost. Based on the analysis of the ozone mass transfer theory, the research status and strengthening mechanism of ozone mass transfer are reviewed from the aspects of improving the structure of gas-liquid contactor, adding the promoter and applying the physical field in this paper. The topics of future development of ozone mass transfer enhancement are also suggested.
