Study on bio-hydrogen production of starch wastewater by anaerobic fermentation technology

Abstract

Bio-hydrogen production of starch wastewater by anaerobic fermentation technology was studied in this paper. The results show that the best conditions of continuous hydrogen production are: the HRT is 8 hours and the temperature of the reactor is 35°C, in which conditions, the hydrogen production rate is up to 195.6 ml/g-starch. At the same time, the starch wastewater is degraded with COD removal of 49.5%∼65.8%.
