(FR) APPAREIL DE TRAITEMENT D'EAUX USÉES POUR L'ÉLIMINATION SIMPLIFIÉE D'AZOTE À L'AIDE D'UNE OXYDATION ANAÉROBIE DE L'AMMONIUM ET D'UNE NITRITATION PARTIELLE À L'AIDE DE GRANULÉS DE BACTÉRIES OXYDANT L'AMMONIUM

Abstract
(EN) The present invention relates to a wastewater treatment apparatus for shortcut nitrogen removal using anaerobic ammonium oxidation (ANAMMOX) and partial nitritation using ammonium oxidizing bacteria (AOB) granules. High-purity AOB granules are formed by means of AOB predominance using a side stream generated during a sludge treatment process. Moreover, the formed AOB granules are supplied to a partial nitritation tank (130) of a main treatment process and thus the partial nitritation is efficiently performed and nitrogen is quickly removed, and thus oxygen and an organic material is reduced compared to an existing method.
(FR) La présente invention concerne un appareil de traitement d'eaux usées pour l'élimination simplifiée d'azote à l'aide d'une oxydation anaérobie de l'ammonium (ANAMMOX) et d'une nitritation partielle à l'aide de granulés de bactéries oxydant l'ammonium (AOB). Des granulés d'AOB de pureté élevée sont formés au moyen d'une prédominance d'AOB à l'aide d'un flux latéral généré pendant un processus de traitement de boue. De plus, les granulés d'AOB formés sont fournis à un réservoir de nitritation partielle (130) d'un processus de traitement principal et, par conséquent, la nitritation partielle est effectuée de manière efficace et l'azote est rapidement éliminé, et ainsi l'oxygène et un matériau organique sont réduits par comparaison à un procédé existant.
(KO) 본 발명은 암모늄 산화 박테리아(AOB, Ammonium Oxidation Bacteria) 그래뉼(granule)을 이용한 부분 아질산화 및 혐기성 암모늄 산화(ANAMMOX; ANaerobic AMMonium OXidation) 공정을 이용한 단축질소제거 공정의 오폐수 처리장치에 관한 것으로, 슬러지 처리공정에서 발생하는 반류수(side stream)를 이용하여 AOB를 우점화하여 고순도의 AOB 그래뉼을 형성한다. 또한, 형성된 AOB 그래뉼을 주처리 공정의 부분 아질산화조(130)로 공급하여 효율적으로 부분 아질산화를 수행함과 동시에 빠르게 질소를 제거하여 기존의 방법보다 산소 및 유기물이 절감되는 발명이다.
