Study on Bio-Hydrogen Production of Different Fermentation Types
By the researches and analyses of the fermentation type in the bio-hydrogen production system, ethanol-type fermentation bacteria had the largest H2-production capability, butyric acid type fermentation bacteria took the second place, and propionic acid-type fermentation bacteria had the least H2-poduction capability. When the organic loading rate (OLR) is 24kgCOD/m3•d, HRT is 8h and temperature is 35 °C, the highest hydrogen production capability corresponding were 4.2, 1.3 and 0.018 mol•kg MLVSS−1•d−1, so ethanol-type fermentation was optimal type for hydrogen production.
