Abstract
A solution containing 2,4-dichlorophenol (DCP) and phenol (or glucose), in the ratio 1:1 in terms of carbon, was fed to a completely mixed continuous flow reactor with recycle and controlled wasting of the activated sludge, operated at steady-state conditions at 20°C. A carefully adapted sludge was able to degrade DCP, besides the accompanying substrate, with no evidence of substrate inhibition in the concentration range covered (156 mg l-1 in the influent). The reactivity order was found to be glucose ≫ phenol > DCP. The results of a series of kinetic runs with phenol + DCP were interpreted by a first-order equation for phenol and by the Monod model for DCP.
