Sequential Anaerobic Fermentative Production of Hydrogen and Methane from Organic Fraction of Municipal Solid Waste
In order to improve the energy recovery efficiency，the fermentative hydrogen production from organic fraction of municipal solid waste(OFMSW)was followed by the methane production using the residual of hydrogen production as substrate. Six varieties of typical individual components of OFMSW including rice，potato，lettuce，lean meat，peanut oil and banyan leaves were selected as experimental materials. Experimental results showed that，during the hydrogen production stage，the hydrogen yields were 125，103，35，0，5 and 0 mL/g-VS for rice，potato，lettuce，lean meat，peanut oil and banyan leaves. The hydrogen composition in the biogas was about 34-59％，41-56％and 37-70％for rice，potato and lettuce respectively. The biogas was free from methane. The energy efficiency was 7.9％，6.8％，1.9％，0，0.1％and 0. During the methane production stage，the methane yields were 232，237，148，278，866 and 50 mL/g-VS respectively. The methane contents were 42-70％，57-71％，73-77％，59％-73％，68-80％and 54-74％. The energy efficiency of co-production hydrogen and methane were 56.3％，58.4％，28.8％，39.2％，81.2％and 8.8％respectively. The total COD removal rate for the whole process of hydrogen and methane production were 72.30％，81.70％，32.63％，47.59％，97.46％and 11.29％.
