Abstract: 

The volumetric flow rate of the second-phase project of the sewage treatment plant in a certain northern city is designed to be 8×104m3/d with the value of average influent BOD5 being 110mg/L and that of average influent TN being 45mg/L, which indicates that the carbon source is far from insufficient. Bardenpho is adopted as the major process of the sewage treatment plant, and efficient suspension filler is added to the first aerobic pool. The Bardenpho process with synchronous nitrogen and phosphorus removal function is characterized by long denitrification sludge age and full use of the carbon source in the zooglea microorganism. The addition of efficient suspension filler into the aerobic pool can increase the amount of micro-organisms and strengthen the nitrification. The combination of the two can ensure a good effect of nitrogen and phosphorus removal without additional carbon source when the carbon source from the influent is insufficient.

Keywords:
