Biological Aerated Filter has the drawback of severe plug under low temperature, and frequent back-washing would cause the bad performance of ammonia removal. To solve these shortcomings, partial backwashing experiment was carried out to test its amelioration effect on Biological Aerated Filter. The result showed that performing backwashing at the 40 cm of filter had strong protective effect on nitrifying bacteria, the ammonia removal could be improved gradually with the highest removal rate of 71.71%. Partial backwashing affected less on ammonia removal and the removal efficiency could be restored to the previous level after the backwashing completed for 2.5 h.
