Biogas production by anaerobic digestion of cattle manure-impact of diet, temperature, pre-storage and co-digestion
In this study manure from dairy cattle was examined in terms of diet,digester temperature,codigestion and prestorage.The manure from cattles fed with 55 different diets was examined for biochemical methane potential (BMP) and chemical composition.From the differnt diets 3 was selected and digested in a continuous system at mesophilic and thermophilic temperatures.One manure type was used for testing 4 selected temperatures during long term experiments allowing for the microorganisms to adapt.The impact on co-digestion was examined at two temperatures with two co-substrates in the form of pelletized wheat straw and wheat straw co-ensiled with beet leaves.Furthermore results from 16 commercial biogas plant treating varying amounts of cattle manure with different process conditions is used for evaluating the influence of temperature and retention time.The losses of methane prior to anaerobic digestion was examined both in labaoratorie experiments and in full scale installations and the impact of mixing other wastes with the cattle manure during storage have been assesed.
