摘    要:为提高光合产氢反应器性能,构建了一种采用沼泽红假单胞菌CQK01接种的光生物产氢-膜曝气生物膜反应器(PBR-MABR)耦合系统。实验表明,在序批培养条件下,由于产氢过程中有机酸和氢离子不断积累,使得PBR系统的产氢速率远低于PBR-MABR系统,其产氢速率为0.49 mmol·(L·h)-1;而PBR-MABR、PBR-2MABRs和PBR-3MABRs的产氢速率则分别可达到0.61、0.76和0.85 mmol·(L·h)-1。这主要是由于有机酸被MABR中的透气膜上生长的生物膜不断降解所致。有机酸的降解不仅提高了耦合系统内pH值并在一定程度上缓解了体系中的产物抑制。

关 键 词:光合产氢反应器   膜曝气生物膜反应器   产氢速率   底物降解

Abstract:To enhance hydrogen production from glucose, membrane-aerated biofilm reactors (MABRs) were coupled with a photobioreactor (PBR) in this study. During a typical fed-batch cycle, the PBR inoculated with Rhodopseudomonas palustris CQK01 exhibited a hydrogen production rate of 0.49 mmol·(L·h)-1. Upon coupling with one, two, or three MABRs, the hydrogen production rate was increased to 0.61, 0.76, and 0.85 mmol·(L·h)-1, respectively. This increase was mainly due to the consumption of large amounts of the accumulated inhibitory byproduct and H+ from the PBR effluent by the biofilms attached to the membrane of the MABRs.
Keywords:photobioreactor  membrane-aerated biofilm bioreactor  hydrogen production rate  substrate degradation
