Summary:The present invention relates to a technology for using ozone (O_3), hydroxyl radical (OH) and a strong alkali solution to regenerate an activated carbon, which is used as an adsorbent of pollutants, simply and economically in order to treat purified water, domestic sewage, industrial wastewater, and livestock wastewater and to remove air pollutants. The present invention provides an integrated system for regenerating the activated carbon, which comprises: a regeneration reaction tank configured to contain activated carbon to be regenerated and a strong alkali solution; an ozone generator generating ozone to be supplied to the regeneration reaction tank; and an acidifier device dispersing ozone supplied to the regeneration reaction tank. 본 발명은 정수 처리, 생활하수 처리, 산업폐수 처리, 축산폐수 처리, 대기오염물질 제거 등을 위해 오염물질의 흡착제로 사용되는 활성탄을 오존(O), 히드록실 라디칼(Hydroxyl radical, OH·) 및 강알칼리용액을 이용하여 간단하고 경제적으로 재생하는 기술에 관한 것이다. 본 발명은 「재생 대상 활성탄 및 강알칼리 용액을 수용하도록 구성된 재생반응조; 오존을 발생시켜 상기 재생반응조에 공급하는 오존발생기 및 상기 재생반응조에 공급되는 오존을 분산시키는 산기장치를 포함하여 구성된 통합형 활성탄 재생 시스템」을 제공한다.
