臭氧吸收及反应过程的传质系数与增强因子

Mass Transfer Coefficients and Enhancement Factors in Ozone Absorption and Ozonation

从双膜理论、溶质渗透理论、膜-渗透理论和表面更新理论出发,研究分析了臭氧气体在液相中的物理吸收过程传质系数,臭氧与液相中的污染物化学反应过程的吸收系数。基于双膜模型理论,推导出在不同pH值区间内伴随着臭氧与污染物化学反应过程的增强因子表达式。

Based on the two-film, the penetration. the film-penetration and the surface renewal theories. mass transfer coetticients for physical absorption of ozone gas in the liquid phase, and chemical absorption for oxidation re-action between ozone and pollutants of liquid phase were studied and analyzed in this paper. A simple explicit ex-pression of enhancement factors for mass transfer accompanied by ozonation of pollutants in different zones of ph val-ues was deduced on the basis of the two-film model.
