摘要

研究了各种操作条件对臭氧降解水中对硝基酚的影响．臭氧化反应在pH=2.0和pH=5.8～12时可分别视为慢反应和拟一级快反应，由此测定出臭氧的液相体积传质系数和对硝基酚的臭氧化反应速率常数，并得到了传质系数的关联式和速率常数的Arrhenius表达式。

Abstract

The influence of operation conditions on the degradation of 4-nitrophenol in water by ozone was studied.The reaction between ozone and 4-nitrophenol can be regarded as slow and fast.pseudo first-order at pH2.0 and pH 5.8—12 respectively.The liquid-phase volumetric mass transfer coefficient of ozone in a bubble reactor and the rate constants were determined.The regression equations of kLa and k2 are expressed as follows
