摘要

Abstract

In this study

high-gravity intensified heterogeneous catalytic ozonation is utilized for treatment of phenol-containing wastewater

and the kinetics of the direct reaction between ozone and phenol in the presence of excess tertiary butanol (TBA) is investigated. It is revealed that the direct reaction between ozone and phenol in the rotating packed bed (RPB) follows the pseudo-first-order kinetics with a reaction rate constant higher than that in the conventional bubbling reactor (BR). Under different conditions of temperature

initial pH

high-gravity factor

and gaseous ozone concentration

the apparent reaction rate constant varies in the range of 0.0160–0.115 min

-1

. An empirical power-exponential model is established to characterize the effects of these parameters on the direct reaction between ozone and phenol by high-gravity intensified heterogeneous catalytic ozonation.
