摘要
针对铬污染土壤,还原稳定化修复技术因具有操作简单、价格低廉、处理效果好等优点,在实际工程中得到广泛应用。对于不同类型的铬污染土壤,选择适用的还原稳定化材料是保证修复效果的关键。基于当前国内、外研究进展,结合国内污染场地应用实例,综述了铬元素的化学性质及影响因素,并对修复材料研究及应用现状等进行系统梳理。同时,结合污染场地特点,通过探讨修复后土壤“返黄”等影响因素,总结出材料修复稳定性与土壤环境条件之间的关系,为铬污染土壤修复工程提供了重要的参考与建议。
The technology of chrome-contaminated soil reduction and stabilization,characterized by its simplicity of operation,cost-efiectiveness,and superior treatment outcomes,has been widely employed in practical engineering endeavors.The selection of appropriate reduction and stabilization materials is crucial in ensuring the efficacy of restoration for various types of chrome-contaminated soils.Based on the current research progress both at home and abroad,and illustrated by the cases of polluted sites within China,this paper provides a comprehensive examination of the chemical properties and influencing factors of chrome elements,as well as a systematic overview of the current research and application status of restoration materials.Moreover,considering the specific characteristics of polluted sites,it evaluates the factors impacting the post-restoration yeUowing of soils,and thereby identies the relationship between Ae stability of the soil environment.This information serves as an important reference and guide for the implementation of restoration engineering projects for chrome-polluted soils.
