Experimental Research on Gas Production with Single Material Waste

To study the effect of biogas production with a single component in the waste, the phenomena of biogas production with the groups of fat powder, cellulose powder and protein powder inoculated respectively in activated sludge from Liu Minying biomass pool and Xiao Hongmen Sewage Plant were observed simultaneously. Six reactors in total were settled. Gas production and the component of the biogas were monitored by GC everyday. Three single materials and the sludge were inspected with infrared spectrometer from the beginning of the installment of the reactors. The results of the experiments show that cellulose powder has the best ability on the respect of methane production, and fat powder is worse than cellulose powder but better than protein powder. On the respect of hydrogen production, protein powder is the best and the other two materials produce gas without hydrogen at all. Compared with sludge from the two different origins, sludge from Liu Minying biomass pool is better both on methane and hydrogen production. The difference of sludge FTIR figures between Liu Minying biomass pool and Xiao Hongmen Sewage Plant can explain this to some degree.
