Sažetak:
Treatment of tobacco dust represents an important problem because of high concentrations of organic compounds, expressed as COD concentration. This research investigated an aerobic biodegradation of leachate from tobacco dust with high concentrations of COD. Experiments were conducted by activated sludge process in batch conditions with different initial concentrations of leachate and different initial concentrations of activated sludge (3.0, 6.0 g dm-3) during 7 hours. Experiments were called Exp. 1 and Exp. 2 with respect to initial concentrations of activated sludge. Values of COD removal efficiency varied from 54.9 to 71.3 % for Exp. 1 and from 59.0 to 77.7 % for Exp. 2. Biokinetic analysis was conducted according to the Monod model. This model gives very good fits to experimental data, accompanied by a high correlation coefficient (R2).
