In the biological aerated filter, the removal efficiency of phosphorus is poor, while the efficiency of organics and nitrogen are very well. In order to solve these problems, the sequence bio-film reactor connects to traditional biological aerated filter, ceramic filler was added to the system, study the effect of bio-film culturing and biological disposal capacity .Control intermittent time of anaerobic and aerobic and aeration volume, the removal effect of COD 、nitrogen and phosphorus are good in the sewage . The results show that anaerobic and aerated time are 3h and 4h in SBBR, the removal efficiency of COD、NH4+-N、TN and TP are 90.07%、85.12%、81.74% and 83.63%, the concentration are 31.37mg/L, 5.15㎎/L, 6.60㎎/L and 1.10㎎/L separately. All of these satisfy theⅠ-B criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). The system of SBBR-BAF run stably, removal sewage perfectly, avoid return and mud, save energy consumption.
