Leachate from municipal solid wastes processed in the treatment plant in Salamanca, Spain has been stabilized by aerobic biological treatment. High organic load (42,310 mg O-2/L COD) and high concentration of K (4376 mg/L) and N (3320 mg/L) make this leachate suitable for agricultural applications, but before agricultural use, biological treatment has to be applied for stabilization and odour reduction. Biodegradability has been studied in aerobic and anaerobic media, showing aerobic (64%) to be more effective than anaerobic (40%) in COD removal. Kinetic study of aerobic-anaerobic biodegradation is presented and a dynamic model for effluent COD prediction in aerobic biological treatment is developed. (c) 2012 Elsevier B.V.
