Evaluation of biodegradation kinetic constants for aromatic compounds by means of aerobic batch experiments.
Kinetics of aerobic biodegradation have been investigated for twenty aromatic species using sludges collected from the aeration basin of municipal sewage treatment plants. The reproducibility of the results is tested with respect to the sludges period of collection and the wastewater treatment plant where they are taken. The comparison of kinetic constants, estimated for the investigated chemicals, allows to evaluate the reactivity effect of single groups (i.e., -OH, -CH3, -Cl, -NO2) into the aromatic structures. The search for easy structure-reactivity relationships is also attempted by means of contributing group methods.
