摘　　要：固化稳定化可以降低土壤中重金属的迁移,被广泛应用于重金属污染土壤修复工程中,是处置重金属污染土壤最常用的技术之一。文章通过调研国内外文献,对固化稳定化的研究进行综述,总结了常用固化稳定化材料,如水泥、碱性材料、黏土矿物质、磷酸盐类材料、金属氧化物和生物炭的研究进展,阐明这些修复材料固化稳定化重金属的基本原理,论述效果评估技术的适用性及局限性,并提出未来研究需求,为以后的固化稳定化修复重金属污染土壤提供参考。Solidification and stabilization technology can reduce the diffusion of heavy metals in soil,it is widely used in the remediation for the heavy metal contaminated soil.Based on the research literature at home and abroad,the study of solidification and stabilization technology was reviewed.The common stabilization materials were summarized,such as cement,alkaline materials,clay minerals,phosphate materials,metal oxide and biochar.The basic principle of fixation of heavy metals by these repair materials was investigated.The applicability and limitations of the techniques were analyzed.And the future research requirements were also proposed.This paper provided a reference for solidification and stabilization for the heavy metal contaminated soil in the future.
