摘要:Biological processes have been proven to be efficient in treating landfill leachates.In this study, treatment of landfill leachate by Ecomat-immobilized mycelia of Ganoderma australe packed in a column was investigated.Continuous recycling of leachate at a constant flow (20 ml/min) was operated for 10 cycles to facilitate biological reactions.Diluted leachate (50%) and raw leachate (100%) were tested for comparison of efficiency of treatment.The results showed that biological oxygen demand (BOD5) was not removed for diluted leachate and a slight removal of 0.14 and 1.72% for raw leachate after cycles 4 and 10, respectively.Chemical oxygen demand (COD) removal occurred after each cycle with diluted leachate demonstrating higher removal compared to raw leachate.The highest percentage of COD removal of 51.62% for diluted leachate and 22.79% for raw leachate were achieved after the tenth cycle.Ecomat-immobilized mycelium of Ganoderma australe could also reduce ammoniacal nitrogen (NH3-N) exhibiting highest reduction of 45.95% and 30.90% after cycle 8 for diluted and raw leachate, respectively.These findings suggested that a white rot fungus, G.australe has the ability to be considered as potential candidate in landfill leachate treatment.
