A research progress in nitrogen conversionAnammox and prosp ects of its application

Abstract

Abstract: The innovative process of nitrogen conversion-anaerobic ammonium oxidation(Ana m mox)-is introduced in the paper.Anammox is a biologically mediated process i n which ammonium is oxidized with nitrite serving as electron acceptor under anaer obic condition.Since the process applied to remove ammonium from wastewater does not need additional COD,consumes less O₂,and produces less secondary sludage, there is a great potential for applying this process to wastewater treatment.It is also worth to explore the existence of anammox process in natural systems suc h as paddy soil,sediments of rivers,lakes and marines.

Key words: Anammox, Nitrogen removal, Autotrophs
