Abstract

The anaerobic ammonium oxidation microbiology can use NH+4 as electron donor,while use NO-3or NO-2 as electron acceptor,then it convert NH-4、NO-3 or NO-2 to N2.As a new method of water treatment,anaerobic ammonium oxidation consumes less energy and needs not carbon source,so it has higher theory importance and good applied prospect.In this article,the domestication and cultivation of anaerobic ammonium oxidation(ANAMMOX) microbiology using activated sludge as seed were studied in a set of SBR system,while the influent was simulated by NH4Cl and NaNO2.In this system,the anaerobic ammonium oxidation could be obsersd.But ammonium and nitrite were not decrease at a fixed rate,meanwhile the ammonium increased.So the domestication and cultivation of anaerobic ammonium oxidation biomass was in the junior stage.
