Innovative Application of Carbon Tube Aerated Membranes to Enhance Anaerobic Baffled Reactor for Wastewater Treatment
炭管曝气膜强化厌氧折流板反应器功能的研究

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, NH4(+) -N and TN. The results showed that on the conditions of intra-membrane pressure of 0.025 MPa, HRT 24 h, influent COD 2000 mg/L, NH4(+) -N 50 mg/L, simultaneous nitrification and denitrification was happened, and COD and NH4(+) -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.
