By incineration treatment became the most important g municipal solid waste disposal method. The bottom ash, which accounting for 20% to 30% of the original municipal solid waste has been a large content source of municipal solid waste in China. The heavy metal will be released to the environment by the eluent produced from the bottom ash. It has a negative influence on bottom ash treatment and reuse. This study analyzed the changing of heavy metals of Cu, Ni and Zn during the elution process by the column simulation experiment. The study revealed the regulation of heavy metals migration under the condition of slow speed elution. These results can help environmental release risk assessment of heavy metal in bottom ash from municipal solid waste incineration plant.
