摘　　要：制作了一种玻璃纤维固定化光合细菌连续产氢反应器,研究了光合细菌的固定化过程及其产气特性,考察了底物中葡萄糖浓度、进料流速以及不同光源对细菌产氢的影响。实验表明,该反应器的最佳产气条件为:LED光源光强2000 lux,葡萄糖浓度6 g/L,进料流速4 mL/min,产氢速率为61 mL/(h·m^2)。玻璃纤维既能增大光能的吸收量,又能增加光合细菌的生物量,从而能提高底物和光能利用率,获得较高的产氢效率。A continuous hydrogen production reactor of photosynthetic bacteria immobilized with glass fiber was fabricated.The immobilization process and gas production characteristics of photosynthetic bacteria were studied.The optimal gas production conditions of the reactor were as follows:LED light intensity 2000 lux,glucose concentration 6 g/L,feed velocity 4 mL/min,hydrogen production rate 61 mL/(h·m^2).Glass fiber can not only increase the absorption amount of light energy,but also increase the biomass of photosynthetic bacteria,so as to improve the substrate and light energy utilization rate and obtain higher hydrogen production efficiency.
