Abstract
Characteristics of biological hydrogen production rate and organic acid under anaerobic fermentation process were investigated with sugar wastewater. Hydrogen production rate was higher with alkaline pre-treatment than acidic pre-treatment, resulting in 70% increment. An adequate supply of the nutrients (N or P) into raw sugar wastewater could increase hydrogen production rate.
Carbohydrate degradation of the anaerobic fermentation process was not directly related with hydrogen production. Sugar wastewater with the addition of the nutrients shows 3 times higher B/A ratio than the raw sugar wastewater. B/A ratio of the wastewater with alkaline pre-treatment and nutrients addition was most higher than other samples, showing 4.02 of B/A ratio. Higher B/A ratio shows higher hydrogen production rate at each sample.
