Bench Scale Study of Fermentative Hydrogen and Methane Production from Food Waste in Integrated Two-stage Process
An integrated two-stage anaerobic digestion process has been investigated,which combined hydrogen and methane production for the treatment of food waste.With a none-heat treatment of inoculum,fermentative hydrogen production has been investigated at difierent organic load rate(OLR)in the first stage(hydrolysis/acetogenesis).The subsequent methane fermentation from the effluent of hydrolysis/acetogenesis phase was assessed as well.The maximum yield of hydrogen(0.065 m3/kg VS·d)and methane(0.546 m3/kg VS·d)were found at the OLR of 22.65 kg VS/m3·d and 4.61 kg VS/m3·d,respectively.Biodegradability test demonstrated that 2.98％ and 90.68％ substrate was degraded in hydrogen fermentation stage and the subsequent methane fermentation stage,respectively.Bench-scale test proved that the hydrogen fermentation coupled with subsequent methane fermentation was emcient and practical on the anaerobic treatment of food waste with none-heat treatment of inoculum.
