An aerobic biodegradation of p-nitro phenol
(PNP) by acclimated waste activated sludge in a
bubble column was examined at varying initial
PNP concentrations, activated sludge
concentrations and aeration rates. For the
aerobic biodegradation of PNP by acclimated
waste activated sludge, the dynamic models for
the dissolved oxygen mass balance and PNP
degradation kinetics with the proposed
correlations for volumetric oxygen transfer
coefficient and oxygen uptake rate could
successfully simulate the concentration profiles
of dissolved oxygen and PNP during the time
course of an aerobic biodegradation of PNP.
