Abstract
In order to investigate the quantitative and qualitative properties of leachate with different composition of MSW in solid waste landfill, three lysimeters filled with bottom ash only (Lysimeter A), bottom ash 70%+municipal solid waste 30% (Lysimeter B), and municipal solid waste only (Lysimeter C) respectively were operated under actual meteorological conditions. From the results, Lysimeter A and Lysimeter B were much higher than Lysimeter C in terms of cumulative generation rates of leachate. The pH in leachate from Lysimeter A are in the range of pH 9 to 11, however, the pH of the leachate was gradually changed to the neutral with time. In the case of CI?, leachates from Lysimeter A and B with bottom ash have high Cl? concentration whereas leachate produced from Lysimeter C has low Cl? concentration. In the Lysimeter C with municipal solid waste only, concentration of organic materials in the leachate was much higher than that of leachate produced from the other Lysimeters.
