This study was carried out to find out safety disposal methods of waste CCA treated wood. The heavy metals of remnant were analyzed after combustion of CCA treated wood at different temperatures. Arsenic volatilized temperature was detected. The removal rate of heavy metals by acid in the ash were examined. Through this study, we could conclude that in order to protect volatilize arsenic, combustion of CCA treated wood should be do under the $300^{\circ}C$. But when CCA treated wood combustion under $300^{\circ}C$, it's weight-loss rate was $55\%$, so land reclamation dependence will be increased. When CCA treated wood combustion at high temperature, the land reclamation dependence could be reduced, but the arsenic that volatilize into the atmosphere should be captured. When it bums with high temperature, the ash contains lots of copper and chromium, so removal of heavy metals should be conducted.
