中文摘要：
对光合细菌生物膜制氢反应器的挂膜启动特性以及成膜稳定后的反应器产氢性能进行了实验研究，探讨了光合细菌生物膜制氯反应器挂膜期间产氢及底物降解规律及稳定成膜后底物浓度对反应器产氢性能的影响。实验结果表明：在生物膜光生物反应器挂膜初期，随着微生物浓度的增大使循环液吸光度、底物消耗和反应器氢气产量迅速升高，进入膜生长期后由于t要是可逆吸附，备参数出现波动，最后在膜稳定期各参数趋于稳定。在稳定成膜后，随着底物浓度的增加，生物膜光生物反应器产氢率先增加，然后降低，存在一个最佳产氢率的底物浓度。
英文摘要：
Experimental investigation was conducted for the study on the start-up behaviors and photo-hydrogen production performance of a photosynthetic bacterial biofilm reactor in this paper. The variation of OD600nm of substrate solution, substrate elimination capacity, and hydrogen yield rate in the start-up stage was studied respectively. The results revealed that OD600nm of substrate solution, substrate elimination capacity, and hydrogen yield rate increased with the increase in the biomass during the biofihn formation stage, then fluctuated in a range in the biofilm development stage which attributed to the reversible absorption, and finally keep almost constant in the biofilm stabilization stage. After the start-up completed, the effect of the inlet substrate concentration on the photo-hydrogen production performance in the biofilm stabilization stage was studied. Experimental results showed that the glucose concentration of 0.12 mol/L exhibited the highest hydrogen yield rate of 3.54 mg/h.
