摘要
In this study, simultaneous carbon. nitrogen and phosphorus (PO43--P) removals using an anoxic/oxic-membrane bioreactor(A/O-MBR) system without any circulation was investigated. The total nitrogen(TN) removal efficiency was above 84.6%, and the average removal efficiencies of COD and PO43--P were 94.6 and 90.0%. respectively. Ammonium (NH4+-N) removal without nitrite (NO2--N) and nitrate (NO3--N) accumulation in the reactor suggested that simultaneous nitrification and denitrification (SND) occurred. The phosphorus-accumulating organisms (PAOs) accumulated in the reactor. AnOx/Oxic test indicated that intracellular organic carbon might be utilized as denitrification electron donor in nitrogen removal process. (C) 2008 Elsevier B.V. All rights reserved.
