초록

Batch experiments were conducted to investigate the effect of organic concentration on the hydrogen production in a dark fermentation process. The organic concentration was varied from 20 to 150 g/L in experiments with a dog food. Anaerobic sludge was treated with 2 N HCl at pH 2 for the enhanced bio-hydrogen production. With added organic concentration of 150 g/L, the maximum hydrogen production was 27 L. But, the maximum hydrogen yield was 280 ml-H2/g-dog food at 80 g-dog food/L. The main production of VFAs are butyrate and acetate. The concentrations of both butyric acid and acetic acid also increased as the organic concentration was increased with the butyric acid concentration increase to a level quadruple that of the acetic acid concentration.
