Abstract: A waste water treatment includes a biological filtration tank, a nitritation tank, and an anammox tank. The biological filtration tank performs biological filtration as a pretreatment process with regard to influent waste water and removes solids and organic matters. The nitritation tank performs a nitritation process with regard to waste water flowing from the biological filtration tank and supplies an electron acceptor needed for removing the organic matter in the biological filtration tank by returning some of the waste water back to the biological filtration tank. The anammox tank performs an anaerobic ammonium oxidizing process with regard to the waste water received from the biological filtration tank and the nitritation tank.

Abstract: 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.

Abstract: The present invention relates to a nitrogen-rich wastewater treatment apparatus using a partial nitritation sequencing batch reactor (SBR) tank, ammonium oxidizing bacteria (AOB) granules and anaerobic ammonium oxidation (ANAMMOX). AOB granules can efficiently be formed by means of a sludge exchange between the SBR tank and an AOB granule production tank. Moreover, partial nitritation is performed by means of allowing the AOB granules to flow into the SBR tank again, nitrogen is quickly removed by means of ANAMMOX without a supply of an external carbon source, and oxygen and an organic material are reduced and a sludge yield decreases compared to an existing method.
