Food waste (FW) and waste activated sludge (WAS) are complementary substrates that improve H2 production by dark fermentation. However, there is little experience in the process performance in the long-term operation of reactors co-processing FW–WAS. This study aims to determine the optimal FW–WAS ratio in batch H2 production and then feed this FW–WAS ratio to an anaerobic sequencing batch reactor (SBR) to evaluate the influence of three organic loading rates (OLR) – 15, 22 and 45 g volatile solids (VS) L−1 d−1 – on H2 performance and microbial composition.

食物垃圾和垃圾活性污泥共消化过程中的生物制氢:有机负荷率的影响和微生物群落的变化

食物垃圾 (FW) 和废弃活性污泥 (WAS) 是互补底物,可通过暗发酵提高 H 2产量。然而,在反应器协同处置FW-WAS的长期运行过程中,工艺性能方面的经验很少。本研究旨在确定批次 H 2生产中的最佳 FW-WAS 比率,然后将该 FW-WAS 比率喂入厌氧序批式反应器 (SBR),以评估三种有机负荷率 (OLR) 的影响 - 15、22 和45 g 挥发性固体 (VS) L −1  d −1 – 对 H 2性能和微生物组成的影响。
