A biofilm photobioreactor under unsaturated flow condition (BFPBR-U) is proposed using a polished optical fiber as the internal light source for photo-H2 production in continuous culture. The main chamber was filled with spherical glass beads to create the reaction bed and the cells were immobilized to form a biofilm under unsaturated flow condition obtained by pumping substrate solution over a packing bed at a rate to create a thin fluid film and injecting the argon to maintain the gas phase space. The effects of operational conditions, including flow rate and influent substrate concentration, on the photo-H2 production performance were investigated. The unsaturated flow conditions eliminated the inhibition caused by high organic loading rate and enhanced light transmission efficiency, leading to an improvement in the photo-H2 production performance.
提出了一种非饱和流动条件下的生物膜光生物反应器（BFPBR-U），该反应器使用抛光光纤作为内部光源，用于连续培养中光催化产氢。主腔室填充有球形玻璃珠以形成反应床，细胞被固定化，在通过以一定速率将底物溶液泵过填充床以形成薄液膜并注入氩气以维持气相空间而获得的非饱和流动条件下形成生物膜。研究了包括流速和进水底物浓度在内的操作条件对光催化产氢性能的影响。非饱和流动条件消除了高有机负荷率引起的抑制作用，并提高了光传输效率，从而改善了光催化产氢性能。
