Influence of the Inoculation Volume on Methanogenesis by Thermophilic Anaerobic Digestion with Residue from Hydrogen Production Fermentation Using Combined Substrate of Sludge and Food Waste

Abstract:

This paper investigated the influence of the inoculation volume of dewatering sludge on thermophilic anaerobic digestion in residue of fermentative hydrogen production using combined sludge and food waste in batch experimental systems. The inoculum to residue ratios were 10%, 30%, 50%, 70%, 90%, respectively. The results showed that the biogas production increased with the inoculation volume except for 90%,and the optimum inoculation volume was 70%.
