Biological phenol degradation was performed experimentally in a gas-liquid-solid fluidized bed bioreactor using a mixed culture of living cells immobilized on activated carbon particles. A comprehensive model was developed for this system utilizing double-substrate limiting kinetics. The model was used to simulate the effects of changing inlet phenol concentration and biofilm thickness on the rate of biodegradation for two different types of support particles. The model shows that gas-liquid mass transfer is the limiting step in the rate of phenol biodegradation when the phenol loading is high.
在气液固流化床生物反应器中，使用固定在活性炭颗粒上的活细胞混合培养物对生物苯酚降解进行了实验研究。利用双底物限制动力学为该系统建立了一个综合模型。该模型用于模拟两种不同类型载体颗粒在入口苯酚浓度和生物膜厚度变化时对生物降解速率的影响。模型表明，当苯酚负荷较高时，气液传质是苯酚生物降解速率的限制步骤。
