提出了一种非饱和流条件下生物膜光生物反应器（BFPBR-U），该生物膜光生物反应器采用抛光光纤作为内光源，在连续培养条件下进行光产氢。用球形玻璃珠填充主室以产生反应床，并且在不饱和流动条件下固定细胞以形成生物膜，所述不饱和流动条件通过以产生薄流体膜的速率将底物溶液泵送过填充床并注入氩气以保持气相空间而获得。考察了流量和进水基质浓度等操作条件对光合产氢性能的影响。非饱和流动条件消除了高有机负载率造成的抑制作用，提高了光透过效率，从而改善了光产氢性能。
A biofilm photobioreactor under unsaturated flow condition (BFPBR-U) is proposed using a polished optical fiber as the internal light source for photo-H2production 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-H2production 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-H2production performance.
