Description

Low hydrogen production which is only 10% of the gas production is a disadvantage of bio-hydrogen production in an anaerobic digestion system. The two-stage AD process can achieve hydrogen production and methane production in two reactors respectively. In most studies, the pH of the hydrogen-producing reactor is controlled at 5.5, at this time the main hydrogen-producing bacteria Clostridium butyricum can have the maximum hydrogen production rate. In addition, HRT, temperature, and the concentration of external additives are also important operating conditions for the two-stage AD process. When the added concentration of NZVI is over 30 mM, the methane production process will be inhibited, but the hydrogen production can be promoted. Therefore, how NZVI promotes hydrogen production in the two-stage AD process is still worthy of attention in the future research.
