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 (A₁) and COD removal (A₂) were obtained by fitting the experimental data. The deviations between experimental and predicted A₁ and A₂ 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.

摘要

本文研究了旋转填充床 (RPB) 中不同有机化合物的降解动力学。选择能与臭氧快速反应的苯酚、邻苯二酚、对苯二酚和苯胺作为模型污染物，建立集总参数模型来表征这些有机化合物在RPB中的快速臭氧化反应速率。通过拟合实验数据得到有机化合物降解( A ₁ )和COD去除( A _{2 )的集中参数的相关性。}实验和预测A ₁和A _{2之间的偏差}一般在25%以内，说明臭氧化速率模型对RPB中臭氧与有机物之间的快速臭氧化具有良好的可预测性。
