Sažetak
Treatment of wastes and leachate evolved in landfills is today an imperative due to rigorous legislation, which intention is to protect an environment. In this work biodegradation of organic fraction in tobacco waste leachate was studied. Experiments were carried out in a sequencing batch reactor at initial concentrations of activated sludge of 3.03 and 5.95 g L-1 and different initial concentrations of organic matter in leachate, expressed as COD concentrations, which were in range from 0.5 to 3.0 g L-1. Results of experiments showed that activated sludge possessed strong ability to degrade organic matter in leachate. Efficiency of biodegradation process was approximately 82.6 %. A simple Monod equation was selected to describe the kinetics of leachate biodegradation. The kinetic parameters Y, kd, μmax and Ks during experiments E1 and E2 were found to be 0.25 g g-1, 0.005 d-1, 0.39 d-1 and 5.45 g L-1, and 0.23 g g-1, 0.003 d-1, 0.44 d-1 and 5.63 g L- 1, respectively.
