<p>A purifying system of livestock waste using microorganisms which controls quality of effluent to a more excellent level and reduces odor of a raw excrement storage tank by substantially lowering a contamination level of residual contamination source after purification of livestock waste as compared with a prescribed standard contamination level for purification of an ordinary septic tank is provided. The purifying system of livestock waste using microorganisms comprises: a raw excrement storage tank(10) having a medium(80) for activating microorganisms to circulate and supply the activated microorganisms; bioreactors(20,30) connected to the raw excrement storage tank by transfer lines; a solid-liquid separator(40) which is connected to the bioreactors by transfer lines, and has a compression dewatering unit(50) integrally formed on a lower part thereof to finally separate a solid component and a liquid component; an aerator(60) for supplying oxygen to the medium of the raw excrement storage tank and to the bioreactors; and a microorganism culture aquarium(70) for culturing microorganisms to circulate and supply, or simply supply the cultured microorganisms, wherein a first supply pipe(110) and a first recovery pipe(120) are installed between the microorganism culture aquarium and the medium, a second supply pipe(115) and a second recovery pipe(125) are also installed between the microorganism culture aquarium and the medium, and a third recovery pipe(127) is installed between the microorganism culture aquarium and the solid-liquid separator.</p> |
