Enhanced microbial adaptation to p-Nitrophenol using activated sludge retained in porous carrier particles and simultaneous removal of nitrite released from degradation of p-Nitrophenol

摘要: In order to examine the microbial degradation of p-nitrophenol (PNP) by a mixed culture system and simultaneous removal nitrite released via degradation, an activated sludge retained in porous carrier particles suspension as control were acclimated artificial sewage containing PNP sole carbon source. The adaptation microbes was faster than that suspended more 20 d. After PNP, it degraded completely without significant accumulation intermediate metabolites. activity 2 times higher microbes. By increasing concentration, from removed denitrification. This research demonstrates using is not only effective for reduction acclimation time but also enables nitrogen compounds resulting nitroaromatics.
