摘　　要：基于Richardson-Zaki液固流态化方程,运用数值模拟分析的方法针对上升流式生物流化床反应器的膨胀行为展开了研究,并建立了相应数学模型.同时以厌氧膨胀颗粒污泥床反应器为例进行了数值模拟研究,数值模拟研究结果很好反映了该反应器的特点且两次相关实验结果的平均相对误差分别为4.74%和8.3%.所得结果显示所建模型以及所采用的数值模拟分析方法基本可行.Simulation analysis of the expansion rate of UBFR was made based on the Richardson-Zaki equation, and its mathematical model was built. And then, the validity of the simulation analysis was verified in EGSB system. The numerical simulation results well show the characteristics of the reactor. The average relative errors of the two experimental results are 4. 74%and 8. 3% respectively. THe obtained results show that the model and the numerical simulation method are workable.
