高压脉冲放电降解水溶液中4-氯酚过程的数学模型(Ⅱ)鼓泡过程中臭氧传质增强因子E与4-氯酚浓度的关系

Mathematical model of 4-chlorophenol degradation in aqueous solution by pulsed high-voltage discharge(Ⅱ)Relationship between enhancement factor of ozone masstransfer and 4-chlorophenol concentration

臭氧从气相传质到废水溶液中并与其中的有机污染物发生氧化还原反应是一个含有化学反应增强的臭氧吸收过程. 在酸性废水中主要发生臭氧与4 -氯酚分子和 4- 氯酚盐离子的反应, 而臭氧在水溶液中分解形成的羟基自由基的氧化作用可以忽略. 提出了由于发生化学反应而形成的臭氧传质增强因子 E与废水中有机物浓度[PCP] 的定量关系的表达式.

The mass transfer of ozone from gas bubble to wastewater aqueous solution was improved by the reaction between the organic compound in the wastewater and ozone.The main reactions taking place in the acid aqueous solution were those between ozone and 4-chlorophenol and 4-chlorophenol salt ion. The reaction between ·OH and the 4-chlorophenol could be neglected.
