| 中文摘要: |
| 矿产资源是人类经济社会发展的重要物质基础，然而在矿产资源的开采过程中，重金属等污染物在土壤环境介质中迁移，最终对矿区生态环境和人体健康造成严重威胁。矿区地质地貌复杂、土壤理化性质变异性大、污染物迁移转化过程复杂、现有土壤污染修复不彻底等成为矿区土壤污染修复主要限制因素。本文通过分析近年来矿区土壤污染修复研究成果，系统提出了构建地形地貌修复基本理念，综述了原位提取、钝化、纳米材料、联合修复以及新理念五类矿区土壤重金属污染修复技术的研究现状和最新研究进展，归纳总结了现有技术的适用范围和优缺点，提出了矿区土壤污染修复技术的未来发展方向，旨在为矿区重金属污染土壤修复的研究与实践提供理论参考。 |
| 英文摘要: |
| Mineral resources are considered significant material sources for economic and social development. However, during mining processes, various toxic pollutants, such as heavy metals, are released into the soil environment, which pose serious threats to the ecological environment and human health in mining areas. In addition, intricate geology, geomorphology, and changes in soil physicochemical properties, as well as complex processes comprising the migration and transformation of pollutants, complicate the remediation of soil environments. Given the lack of existing technology, such as inadequate soil remediation, we analyzed the recent achievements in the remediation of contaminated soils in mining areas and introduced the basic concept of land restoration. Moreover, we introduced the theoretical and experimental research status of five types of typical treatment technologies for heavy metals, including extraction, passivation, nanotechnology, combination, and new concept techniques in detail; subsequently, we also described the advantages and limitations of the application of existing remediation techniques. This study aims to provide directions for future research on soil pollution control, treatment technologies, and remediation practices in mining areas. |
