摘　　要：利用合成的侧链高分子化合物配位稳定火化飞灰中的重金属,并配合石灰固化飞灰与土壤的混合物,实现飞灰的无害直接填埋。实验室有毒物质检测程序(TCLP)检测得到的重金属浸出量符合废物填埋控制标准。飞灰粘土固化件无侧限抗压强度达到2 MPa以上,水稳定性好,长期抗渗透能力高。A branch polymer is synthesized to coordinate and stabilize the heavy metal ions in fly ash. Cooperating with slaked lime, the polymer could also solidify the mixture of fly ash and soil to realize the innocuous landfill. The result of Toxicity Characteristic Leaching Procedure（TCLP） shows that the leaching amount of heavy metals meets the control standard of landfill. The solidification mixture has an over 2MPa unconfined compressive strength and good waterstability.
