Degradation Kinetics Study of Fast Ozonation Reaction in a Rotating Packed Bed

ABSTRACT The degradation kinetics of different organic compounds in a rotating packed bed (RPB) were investigated in this work. Phenol, catechol, hydroquinone, and aniline that can react rapidly with ozone were chosen to be the model pollutants, and the lumped parameter models were established to characterize the reaction rate of fast ozonation of those organic compounds in the RPB. Correlations for the lumped parameters of the organic compounds degradation (A 1) and COD removal (A 2) were obtained by fitting the experimental data. The deviations between experimental and predicted A 1 and A 2 were generally within 25%, indicating that the ozonation rate model has a good predictability for fast ozonation between ozone and organic compounds in the RPB.
