Abstract
Our research was carried out to estimate leaching characteristics of bottom incineration residues from municipal solid waste incinerators. Organic compounds in raw ash, leaching water, and leaching residue were qualitatively analyzed. A total of 44 organic compounds, contained in bottom ashes were nalyed by GC/MSD with wiley library search. Botton ashes were found to contain a wide range of orgainc compounds such as aliphatic and aromatic compounds. Compounds in raw ash, leaching water and residues from bottom ash were detected Ethenylbenzene, Benzaldehyde, 1-Phenyl-Ethanone and 1,4-Benzenedicarboxylic acid dimethyl ester. The leaching characteristics of incineration residue, leads us to fllowing conclusim that the single landfill of incineration residue can contaminate the soil and undergroundwater. In order to prevent environmental contamination by the organic compounds as well as extremely toxic substances in the bottom ash, it is particularlyimportant that the incineration residues should be treated so as to decrease the concentration of the compounds before disposal and be studied about leaching characteristics of organic compounds contained in bottom ash.
