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。
