Experimental study on simultaneous removal of nitrogen and phosphorus in CAS-BT hybrid biological reactor
CAS-BT复合反应器同步脱氮除磷试验研究

The biofilm using self-made suspended media as carrier was put in the CAST reactor, then a CAS-BT hybrid biological reactor was constituted. The effect of simultaneous removal of nitrogen and phosphorus in CAS-BT hybrid biological reactor was studied. When the concentration of TN and TP was about 25 mg/L and 180 mg/L respectively in the raw wastewater, the result of simultaneous removal of nitrogen and phosphorus was good and the removal rates of TN and TP could reach to 96.46% and 98.10%, respectively. It proved that there were advantages for CAS-BT in the process of simultaneous removal of nitrogen and phosphorus.
