摘　　要：化学还原稳定化修复是工业铬污染土壤修复中应用最为广泛的技术。针对不同污染程度及理化性质的铬污染土壤,选择最为高效、经济、适用的稳定化修复材料是铬污染土壤修复工程最核心问题所在。针对上述问题,重点对现有铬污染土壤修复材料,如铁系、硫系、铁硫系、有机类及微生物菌剂的修复原理、影响因素、实际应用效果及存在问题、修复后环境风险和长期稳定性等多方面进行总结,为实际修复工程中六价铬修复材料的选择及修复实践工作的开展提供重要参考与指导建议。Chemical reduction stabilization remediation is the most widely used technology for remediation of chromium contaminated soils.How to select the most efficient,economical and applicable remediation materials for chromiumcontaminated soil with different pollution degrees and physicochemical properties is the core problem of chromium-contaminated soil remediation engineering.This paper mainly focused on the remediation principles,influencing factors,the actual application effect and the existing problems,the environmental risk and long-term stability of chromium-contaminated soil remediation materials,such as iron-based,sulfur-based,iron-sulfur-based,organic and microbial agents,to the reduction of hexavalent chromium-contaminated soil.It can provide references and guidance for better application of those remediation materials in the practical engineering.
