Phenol biodegradation in a batch jet loop bioreactor (JLB) using activated sludge was investigated. The biodegradation experiments were conducted at different phenol concentrations (S(0)) from 50 to 1000 mg/l. The results of the biodegradation of phenol by JLB show that a good phenol removal of 100%. The biodegradation capacity of the JLB was higher than that of the stirred tank reactor reported in literatures. The Haldane equation was adopted in order to describe the relation between the specific growth rates (micro) and S(0). Kinetic constants of Haldane equation were micro(m) = 0.119 1/h, K(s) = 11.13 mg/l and K(i) = 250.88 mg/l. Model equations were simulated using the MATHCAD 7.0 software's ordinary differential equation solver. Simulations were performed at each experiment with different initial phenol concentrations.
采用活性污泥在批式射流环生物反应器（JLB）中研究了苯酚的生物降解。在不同的苯酚浓度（S(0)）下进行了生物降解实验，范围为 50 至 1000 mg/L。JLB 中苯酚生物降解的结果表明，苯酚的去除率达到了 100%。JLB 的生物降解能力高于文献中报道的搅拌釜式反应器。采用 Haldane 方程来描述比生长速率（μ）与 S(0)之间的关系。Haldane 方程的动力学常数为 μ(m) = 0.119 1/h，K(s) = 11.13 mg/L 和 K(i) = 250.88 mg/L。使用 MATHCAD 7.0 软件的常微分方程求解器对模型方程进行了模拟。在每个实验中，使用不同的初始苯酚浓度进行了模拟。
