【摘要】 在充填软性纤维材料的玻璃柱式反应器中,利用Rhodopseudomonas polustris Y₆光合细菌（PSB）连续处理发酵废液。建立了该处理系统动力学模型。计算出模型参数:K_?=45.56mg/ml,μm=0.224h^-1。模型理论曲线与实验值较吻合。研究得出较适合的稀释率D_opt为0.129h^-1,此时COD去除能力最大为1686.0ppm COD/h。本文为纤维载体固定化PSB处理有机废水提供了一些放大操作依据。更多还原

【Abstract】 Waste water was continuously treated in a glass columnar bioreactor with Rhodopseudomonas palustris Y₆. A kinetic model of the bioreactor system was established. With the data obtained the model coefficients K, and μ_m have been calculated to be 45.56 mg/ml and 0.22h^-1 respectively. Good agreements between model prediction and the experimental data were achieved. The optimal operation condition is found, when D_op, is 0.129 h^-1, at that dilution rate the maximal COD reduction capacity is 1686.0 ppmCOD/h. The results presented in this paper provide a useful basis for further scale-up and operation.更多还原
