NOVELTY - The system has primary reaction tank (430) to carry out primary fermentation of filtrate, to acquire primary fermented liquor. A secondary reaction tank (450) is provided to carry out secondary fermentation of primary fermented liquor using composition for livestock farming excrement processing, to acquire secondary fermented liquor. A sedimentation tank (470) is provided to separate secondary fermented liquor into supernatant water and sludge. A selector (550) is set to select manure rotted down by after-mature tank (530) which rots down manure cured using stirring vessel (510).    USE - Livestock farming excreta-processing system for separating livestock farming excrement such as cow feces-urine and pig feces-urine into solid content and filtrate.    ADVANTAGE - The livestock farming excreta-processing is performed effectively for separating livestock farming excrement into solid content and filtrate, by providing sedimentation tank to separate secondary fermented liquor into supernatant water and sludge.    DETAILED DESCRIPTION - The excrement reservoir (150) is located in lower-stage portion of livestock barn, for storing livestock farming excrement. The collection tub (200) is provided to collect livestock farming excrement from excrement reservoir. The solid-liquid separation device (300) is provided to separate livestock farming excrement into filtrate and solid content. The composition of livestock farming excrement processing supplied from composting system (500) and sludge supplied from solid content separated from solid-liquid-separation device are thrown into stirring vessel. The packaging device (570) is provided to package manure selected with selector. The anaerobic fermentation of the livestock farming wastewater is carried out for ten to twenty days, while aerating for ten to thirty days and carrying out metabolism activities of microorganisms using metabolite. 1-10 weight portion of microorganisms mixed with strains containing sludge is precipitated, after carrying out aerobic fermentation of the livestock farming wastewater by aerator. 15-40 weight portion of bio-activation substances containing supernatant and humic acids is precipitated and separated. 10-30 weight portion of composition for livestock farming excrement processing is put in first reaction tank with respect to specific weight portion of filtrates. 30-60 weight portion of composition for livestock farming excrement processing is put in second reaction tank with respect to first fermented liquor. The liquid fertilizer stored in liquid fertilizer storage tank (490) is used for circulating water supplied to excrement storage tank. 50-60 weight portion of water and 0.1-0.5 weight portion of composition for livestock farming excrement processing are mixed with respect to 100 weight portion of sludge supplied from solid content separated from solid liquid separation device. The selected manure is cured for ten to eleven days in the stirring vessel, and made to rot down for 50-52 days in after-mature tank.
