본 발명에 따른 수전해기의 부생 산소를 활용해 생산된 과산화수소를 이용한 수처리 시스템은, 수전해기에서 생성된 고순도의 부생 산소를 활용하여 과산화수소를 생성하고, 상기 과산화수소를 자외선 반응을 통해 하이드록실 라디칼을 생성하고, 고도산화 수처리에 활용하도록 구성됨으로써, 수전해 시스템과 수처리 시스템의 연계를 통해 부생 산소의 현장(on-site) 활용이 가능해짐에 따라 별도의 산소 액화, 저장, 운반 및 주입 설비 등이 필요하지 않으므로 설비가 간단해지고, 오존과 과산화수소 구매 비용 등 운영 비용이 절감될 수 있다. 또한, 수전해기의 산소 생산량, 피처리수의 오염도, 피처리수의 양 등에 따라 간접적 안트라퀴논 공정의 제1과산화수소 생성기와 전기화학적 반응을 하는 제2과산화수소 생성기 중 적어도 하나가 선택적으로 사용될 수 있으므로, 과산화수소 생산 효율과 수처리 효율이 보다 향상될 수 있다. 또한, 기체 수소가 반응물로 투입되지 않는 간접적 안트라퀴논 공정 및 전기화학적 2전자 산소환원반응을 통해 과산화수소를 생산하여 수처리에 사용하기 때문에, 효율적인 운영이 가능해질 수 있다. 또한, 산소의 생산과 수요를 직접 연결시킴으로써 경제성도 향상될 수 있다.
