Abstract:

Laboratory-scale experiments on aerobicanaerobic operations of the sequencing batch reactor SBR activated sludge processes, in which methanol was added as a hydrogen donor, were conducted to remove nitrogen and refractory organic compounds in municipal landfill leachate. The NH 4-N concentrations in leachate from landfill ranged from 100 to 200 mgl. A high concentration of nonbiodegradable organic compound 100 to 150 mgl as chemical oxygen demand COD was observed in the leachate. Ninety-five percent or more nitrogen removal was achieved in the operation with an optimum length of aerobic and anoxicanaerobic period for the nitrification-denitrification process. Fifty percent or more removal of refractory organic compounds was achieved by the SBR activated sludge process with the addition of ozonation pretreatment.
