" Evaluation on the Energy Potential of Livestock Manure in the Upstream Areas "

In Korea, surface water has been used as a main water resource; in particular, upstream areas are mainly used as drinking water sources. Unfortunately, these areas are exposed to many pollutants, of which livestock manure used as compost is becoming a significant pollutant during rainfall events. The aim of this study is to evaluate the utilization of livestock manure generated in the upstream areas of adam as an energy resource. Anaerobic digestion processes are used for the biological degradation of organic wastes and for biogas generation. Therefore, in this study, the energy potential of livestock manure was evaluated for the prevention of inflow into the water bodies based onfour themes: the comparison of biogas generation by various types of livestock manure, the evaluation of the energy potential of livestock manure as a solid refuse fuel after anaerobic digestion, the composting period''s effect on the biogas generation yield, and the ammonium nitrogen inhibition. The amount of biogas produced by cattle manure that lacked organic matter was the lowest, but it had the highest low calorific value of about 3,500 kcal/kg, which means that it can be used as a combustion aid substrate . It can be noted that the amount of biogas generated decreased due to the decomposition of organic matter as a result of the composting of cattle manure.
