Preparation and performance of biologically activated bamboo charcoal for removing quinoline

A strain of bacterium (BC027) for quinoline degradation was inoculated on the activated bamboo charcoal (ABC) substrate. SEM observation showed that the bacterium grew well on the charcoal substrate and thus obtained biologically activated bamboo charcoal (BABC). The investigation on quinoline removal showed that BABC has greater capacity for removing quinoline than ABC or dissociate BC027. The removal ability of BABC is influenced by initial concentration and domestication process. Adsorption of carbon substrate only occurred at the beginning stage, while it had no effect on the bacterium inoculation and activity. The bacteria enhanced the treatment capacity of ABC and prolonged its usage life.
