A process combining an Anaerobic Baffled Reactor (ABR) and a constructed wetland was employed to treat nitrobenzene wastewater. The overall performance was examined throughout long-term operation with a hydraulic retention time (HRT) of 24 h at 30 +/- 1 degrees C. The effluent nitrobenzene concentration of the ABR and constructed wetland was less than 4.81 and 1.94 mg/L, respectively, with an initial nitrobenzene concentration of 80 mg/L at the steady-state periods. The corresponding removal efficiencies were 97.02% and 73.93%, respectively. Moreover, 97.29% of aniline produced in the ABR could be removed in the subsequent wetland. The number of sequenced clones from each library was sufficient to cover archaea and eubacteria diversity at the species level and to obtain a representation of the total microbial diversity in the ABR. The predominant microbial populations in the ABR were identified as Pseudomonas putida, Methanosaeta concilii and Methanothrix soehngenii. Crown Copyright (C) 2012 Published by Elsevier Ltd.
