초록

혐기성 암모늄산화(ANAMMOX)는 고농도 질소폐수를 처리하기 위한 획기적인 공정이다. 본 연구에서는 고농도 암모늄 및 유기물을 함유한 고농도 폐수를 ANAMMOX 공정을 이용하여 처리하는 동안 일어나는 유기물질의 산발효, 탈질, 황화합물의 환원 및 hydroxyapatite에 의한 인의 결정화에 대하여 연구하였다. 또한, ANAMMOX 공정의 중간생성물인 hydroxylamine과 hydrazine의 기능을 조사하였다. 연구결과, 돈사폐수의 혐기성 암모니아산화 반응과 함께 다양한 복합반응이 일어나며, hydroxylamine과 hydrazine은 ANAMMOX 반응에 중요한 역할을 하는 것으로 나타났다.

Anaerobic ammonium oxidation(ANAMMOX) is a novel process fur treatment of piggery waste with strong nitrogen. In this study, we investigated acid fermentation of organic matter, denitrificatiot reduction of sulfur compounds and P crystalization by hydroxyapatite during the treatment of wastewater with high strength of ammonium and organic matters by ANAMMOX process. Also, functions of hydroxylamine and hydrazine as intermedeates of ANAMMOX process were tested. This study reveals that various complex-reactions with anaerobic ammonium oxidation of piggery waste are happened and hydroxylamine and hydrazine play an important role in ANAMMOX reaction.
