The effects of air/water ratio, hydraulic loading and the length of LBAF on pollutants removal efficiency are tested. The results show that under optimal technological conditions when hydraulic loading is 0.43 m3 m?2 h?1 and air/water ratio is 10:1, the average removal efficiencies of COD, SS, NH3-N, and TN reach 88.01%, 95.18%, 78.97% and 52.58%, respectively. An LBAF has a large pollutants handling capacity; is less liable to be blocked, and has a longer operation cycle in comparison with a traditional BAF.展开更多
