NOVELTY - Aerobic liquefied fertilizer production system comprises: a liquefied fertilizer reservoir, whose inner portion provided with a carrier pump for flowing aged liquefied fertilizer to an aerobic liquefied fertilizer tub; an air supply pipe; a solid-liquid separator; a first reservoir; a second reservoir; a bioreactor for culturing nitrifying microorganisms or acid-forming bacteria; and multiple aerobic liquefied fertilizer tubs, where the fully aged liquefied fertilizer is transferred from the aerobic liquefied fertilizer tub.    USE - Used as an aerobic liquefied fertilizer production system.    ADVANTAGE - The system reduces energy and water utilization, prevents odor due to agitation, and provides high fertilizer productivity.    DETAILED DESCRIPTION - Aerobic liquefied fertilizer production system comprises: a liquefied fertilizer reservoir, whose inner portion provided with a carrier pump for flowing aged liquefied fertilizer to an aerobic liquefied fertilizer tub; an air supply pipe; a solid-liquid separator; a first reservoir for the livestock excretion flowed out from a livestock shed and which stores through the feed pump and mixes the solid livestock excretion and the liquid livestock excretion filtrate using mixer installed at the inner portion, where the livestock excretion filtrate is separated from an aerator receiving the livestock excretion transferred from the first reservoir; a second reservoir to accommodate localized manure filtrate using a mixing agitator installed inside a mixing tank; a bioreactor for culturing nitrifying microorganisms or acid-forming bacteria while accepting the livestock excretion filtrate supplied with aeration; and multiple aerobic liquefied fertilizer tubs annihilating harmful microorganism processing successively as excrement which included in the livestock excretion filtrate in the reaction temperature of 30-80 degrees C using the bioreactor, where the fully aged liquefied fertilizer is transferred from the aerobic liquefied fertilizer tub installed at multiple aerobic liquefied fertilizer tubs. An INDEPENDENT CLAIM is also included for aerobic processing including the intermittently circulation of the liquefied fertilizer and high temperature sterilization, comprising: transferring solid and liquid animal wastes through a pump from the reservoir, separating the animal wastes by solid-liquid separator; transferring the filtrate from the reservoir to accommodate the aeration; mixing the filtrate in the mixing tank with the nitrifying microorganisms or acid-forming bacteria, selectively culturing the microorganism and the microorganism on culture medium being supplied from the outside and aeration supplied from the air bath at a reaction temperature of 30-80 degrees C to kill harmful microorganisms present in the filtrate; and transferring the aged liquid manure.
