Abstract:The anaerobic ammonia oxidation(Anammox) bioreactor was successfully started up with the nitrifying activated sludge. After anaerobically operated for 105 d, the bioreactor reached a good performance with removal percentage of both ammonia and nitrite higher than 95% and volumetric total nitrogen removal as high as 149.55 mmol/( L.d). The soft padding made an important contribution to the high efficiency and stability because it held a large amount of biomass in the bioreactor.
