Abstract

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.
旋转填料床快速臭氧化反应降解动力学研究
研究了不同有机化合物在旋转填料床(RPB)中的降解动力学。选择苯酚、儿茶酚、对苯二酚和苯胺等能与臭氧快速反应的污染物作为模型污染物,建立了集总参数模型,表征了这些有机化合物在RPB中快速臭氧化的反应速率。通过对实验数据的拟合,得到了有机化合物降解(a1)和COD去除率(a2)的集总参数的相关性。实验a1和a2与预测值的偏差一般在25%以内,表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较好的可预测性。
