| New type hybrid biological reactor was developed by initiating the carbon membrane aeration in ABR which was augmented with carbon aerated membranes to improve wastewater treatment by removing COD, NH+4-N and TN.The results showed that on the conditions of intra-membrane pressure of 0.025 MPa, HRT 24 h, influent COD 2 000 mg/L, NH+4-N 50 mg/L, simultaneous nitrification and denitrification was happened, and COD and NH+4-N decreased from 156 mg/L，36 mg/L to 45 mg/L，6 mg/L respectively after the membrane aeration with biofilm was initiated in the third compartment of ABR.TN removal reached 87.66%, and VFA and biogas was decreased by 77.12% and 30%, respectively. |
