Organic Carbon and Nitrogen Removal in a modified Anozic/Ozic-Membrane Bioreactor treating high strength wastewater
In this study, the feasibility of simultaneous nitrification and denitrification (SND) in an anoxic/oxic membrane bioreactor (A/O-MBR) without any recirculation was investigated. It was found that SND occurred in the bioreactor. The influent ammonia converted to NO2--N and NO3--N via the nitrification process and then further reduced to gaseous nitrogen, directly. It is possible that the aerobic denitrifying bacteria and the partly micro condition play the combination role. Therefore, the high CODCr and total nitrogen (TN) removal efficiencies of 96.7％ and 94.7％ were achieved in the combination system, successfully, regardless of varying influent COD concentration (500-2200 mg L-1) and NH4+-N concentration (50-200 mg L-1).
