摘　　要：为了研究折流板式光合生物制氢反应器(anaerobic baffled reactor, ABR)运行过程中传热传质的机理,将Monod生物动力学模型与生物制氢底物消耗动力学相结合,使用数值模拟研究不同条件下反应器内葡萄糖消耗过程中传热、传质和化学反应引起的熵产率,在此基础上分析光合细菌对葡萄糖的消耗速率和产氢速率,以单位氢气生成速率的熵产率最小作为评价原则对反应器的运行条件进行优化。结果表明,各因素对折流板式光合生物氢反应器性能的影响主次顺序依次为:光照强度、溶液温度、壁面温度、底物初始浓度和水力滞留期。最佳运行条件为:培养液温度为30℃,反应器壁面温度为30℃,光照强度为6 000 lx,反应器水力滞留期为12 h,培养液葡萄糖质量为150 mol/m^(3)。In order to investigate the mechanism of heat and mass transfer during the operation of the anaerobic baffled reactor(ABR), the Monod biokinetic model was combined with the kinetics of biohydrogen substrate consumption to numerically analyze the entropy generation rate caused by heat, mass and chemical reactions during glucose consumption in the reactor under different conditions. The rates of glucose consumption and hydrogen production by photosynthetic bacteria were analyzed, and the operating conditions of the reactor were optimized using the minimum entropy generation rate for per unit hydrogen production rate as the evaluation principle. The results showed that the main order of factors affecting the performance of the folded plate type photosynthetic biohydrogen reactor is: light intensity, solution temperature, wall temperature, initial substrate concentration and hydraulic retention period. The optimum operating conditions are: culture solution temperature of 30 ℃, reactor wall temperature of 30 ℃, light intensity of 6 000 lx, reactor hydraulic retention period of 12 h and culture solution glucose concentration of 150 mol/m^(3).
