| Abstract: | Bio-nitrification technology is discussed in the processes of the deep bed filtration in this paper. The result of experiment proves that the order of reaction of bio-nitrification kinetics is zero and the relationship of the concentration of ammonia as well as the nitrate and HRT or height of deep bed is provided well with linearity. The effect of the dissolving oxygen and HRT on removal efficiency or reaction processes is discussed. The effect of backwashing technique on removal efficiency of ammonia is analyzed. |
