根据化工过程的气液反应理论对饮用水深度净化工艺中臭氧化单元操作进行探讨，在扩散方程的一维模型和双膜理论的基本方程的基础上，通过对三种不同径孔扩微散器的总传质系数ＫＧα的测试和比较，对臭氧接触装置的工作效能进行了评价。
According to the gas-liquid reaction theory of chemical process, the operation of ozonation unit in the deep purification process of drinking water is discussed. Based on the one-dimensional model of the diffusion equation and the basic equation of the double-film theory, three different diameters of holes are spread and dispersed. The total mass transfer coefficient KGα of the device was tested and compared, and the performance of the ozone contact device was evaluated.
