摘要: The system performance of a trickle-bed air biofilter (TBAB) for treating acrylonitrile (AN) vapor from waste gases was investigated under different gas flow rates and influent AN concentrations. In steady-state conditions, the AN elimination capacity increased bur the AN removal efficiency decreased with the increase of influent AN load. More than 95% AN removals were achieved for AN loads below 490 g AN m(-3) h(-1). The TBAB appeared to be a very effective treatment process for removing AN vapor at low to high loads, and the effectiveness could be maintained over a long period. Most AN vapors were removed in the earlier stages, indicating that a three-stage TBAB might be sufficient in the practical application. (C) 2000 Published by Elsevier Science Ltd.
