Influence of ligands on metals leachability from landfilling bottom ashes

摘要

After municipal solid waste is incinerated, its bottom ash used to be disposed by landfill. Although the leachate quality is less polluted, some heavy metals in the bottom ashes are affected By ligands, which raise their release potential. Concerned by the bottom ashes landfilling, this Research explored the influence strengths of ligands in leaching heavy metals, by rotary extraction And lysimeter leaching test.
