Title
Process Optimization of Landfill Leachate Treatment with White Rot Fungi
김기은 Gi Eun Kim
Abstract
In this study a process for the leachate treatment has been optimized. A packed column reactor system was used for the treatment of leachate. The cells of white rot fungi are immobilized on the glass beads in the reactor. The cells of Phanerochaete chrysosporium could grow up in a leachate solution without additional substances and produce extracelluar enzymes. The decrease of COD value and ammonia concentration relied on the cell growth. After 7 days COD, BOD and ammonia were removed 30%, 82% and 67%, respectively. After reaction kinetics there is a suggestion that a leachate with high content of ammonia can be well adaptable for microbial treatment. In the reactor most of ammonia were degraded by microbial cells and higher enzyme concentration could increase removal rate. For a higher efficiency a packed column system with microbial cells was tested. In the packed column reactor immobilized with the white rot fungi cells more than 80% of BOD and almost of ammonia were removed, but COD under 30%. The glass beads may not the best carrier for fungi cells or leachate treatment. A further study will be necessary about variable carriers for the optimization of the system.
