NOVELTY - Organic waste treatment system comprises a solid-liquid separation unit (100) for separating organic waste solids and wastewater, a waste water purification unit with electronic beam irradiation part (240) for irradiating the waste water discharged from the solid-liquid separation unit with electron beam to carry out aeration by ozone air bubbles, a biogas generation unit (300) to produce biogas from solid materials separated from the solid-liquid separation unit, and an electron beam reaction part (400) for modification of methane gas generated in the biogas generation unit.    USE - Used as organic waste treatment system.    ADVANTAGE - The system: purifies biogas from organic waste generated during the process; recovers waste water and exhaust gas; and actively controls the ozone concentration by detecting its concentration.    DETAILED DESCRIPTION - Organic waste treatment system comprises a solid-liquid separation unit (100) for separating organic waste solids and wastewater, a waste water purification unit with electronic beam irradiation part (240) for irradiating the waste water discharged from the solid-liquid separation unit with electron beam to carry out aeration by ozone air bubbles, a biogas generation unit (300) to produce biogas from solid materials separated from the solid-liquid separation unit, an electron beam reaction part (400) for modification of methane gas generated in the biogas generation unit and removal of malodorous substances, an ozone generation unit for supplying ozone to the waste water purification unit, a control unit (600) for controlling the ozone generation unit and the waste water purification unit to detect and adjust the amount of ozone to be supplied and control ozone concentration in the wastewater and controlling malodorous substances released from the electron beam irradiation part.
