The anaerobic ammonia oxidation (Anammox) bioreactor wa s succe ssfully started up with the nitrifying activated sludge. After anaerobically operated for 105d, the bioreactor reached agood performance with removal percentage of both ammonia and nitrite higher than 95% and volumetric total nitrogen removal as high as 149155mmolP(L•d). The soft padding made an important contribution to the high efficiency and stability because it held a large amount of bioma ss in the bioreactor.

The anaerobic ammonia oxidation (Anammox) granular sludge bed reactor was started up succe ssfully with nitrifying granular sludge. During the operation, the nitrifying granular sludge was gradually converted into Anammox granular sludge with good settling property and high conversion activity. The Anammox reactor worked well with the shorte st HRT of 2143h. Under the condition that HRT was 6139 h and influent concentration of ammonia and nitrite wa s 10mmolPL, the removal of ammonia and nitrite was 97117% and 100100%, re spectively. Corre sponding volumetric total nitrogen loading rate and volumetric total nitrogen conversion rate were 100183mmolP(L•d) and 98195 mmolP(L•d). The performance of Anammox reactor wa s efficient and stable.
