Removal of Nitrogen and Refractory organic Compounds in Municipal Landfill Leachate by Sequencing Batch Reactor Activated Sludge Processes,
Abstract
Laboratory-scale experiments on aerobic/anaerobic 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 mg/l. A high concentration of nonbiodegradable organic compound (100 to 150 mg/l 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 anoxic/anaerobic 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.
