The present invention relates to a hydrolysis apparatus for solid livestock manure that can be integrated with a wet anaerobic digestion system. More specifically, the invention aims to: enable the utilization of solid livestock manure, which has previously been excluded from anaerobic digestion, as a feedstock for anaerobic digestion; diversify the treatment methods for solid livestock manure, which has conventionally been handled almost exclusively by composting; enable the use of solid livestock manure as a bioenergy source, thereby contributing to the promotion of biogas production in the livestock sector; and drastically reduce greenhouse gas emissions originating from livestock manure through anaerobic digestion of solid livestock manure (approximately 36 to 206 kg of greenhouse gases can be reduced per ton of livestock manure), thereby securing an additional source of income through carbon emissions trading. To this end, the present invention discloses a wet anaerobic digestion-linked hydrolysis apparatus for solid livestock manure.
