摘要： Disclosed is a method for removing nitrogen and phosphorus from sewage and wastewater through a combination of a biological nitrogen and phosphorus removal process using nitrite nitrogen and an anaerobic ammonium oxidation process. An objective of an embodiment of the present invention is to provide an apparatus for removing nitrogen and phosphorus in which, by inducing a denitritation- and nitritation-based biological nitrogen and phosphorus removal process in a bioreactor and applying an anaerobic ammonium oxidation process, nitrogen and phosphorus can be economically and effectively removed without separately injecting organic materials.

摘要： 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.
