Study on Nitrogen Removal Efficiency of Hybrid Anoxic/Aerobic Membrane Bioreactor

Abstract:

Based on fillers theory and traditional A/O-MBR theory, anoxic/aerobic hybrid membrane bioreactor system (A/O-HMBR for short) was modified by adding suspended biological fillers in one of the aerobic tanks of the traditional A/O-MBR, in which the filling ratio of fillers was 8%. The thesis mainly studies the nitrogen removal effect in the A/O-HMBR system when the main influence parameters, such as influent C/N(5,7,10), aeration intensity(15m³/h,20m³/h,25m³/h) and HRT(5h,8h,11h), were changed.The experimental results show that when HRT was 8h, C/N was 7, and aeration intensity was 20m³/h, TN removal effect was best.
