The ozone treatment for enhancement of biodegradability of persistent organic pollutants in landfill leachates and subsequent biological treatment were studied. Transformation of pollutants was assessed using the chemical oxygen demand (COD) and biochemical oxygen demand (BOD) values. Biological tests were carried out in order to evaluate the potential of biological treatment of ozonated landfill leachates. The potential of biological processes for treatment of ozonated landfill leachates followed from the results of nitrification and denitrification tests.
