Contaminated soils have caused serious harm to human health and the ecological environment due to the high toxicity of organic and inorganic pollutants, which has attracted extensive attention in recent years. Because of its low cost, simple operation and high efficiency, soil washing technology is widely used to permanently remove various pollutants in contaminated soils and is considered to be the most promising remediation technology. This review summarized the recent developments in the field of soil washing technology and discusses the application of conventional washing agents, advanced emerging washing agents, the recycling of washing effluents and the combination of soil washing and other remediation technologies. Overall, the findings provide a comprehensive understanding of soil washing technology and suggest some potential improvements from a scientific and practical point of view.
由于有机和无机污染物的高毒性，受污染土壤已对人类健康和生态环境造成严重危害，近年来这一问题已引起广泛关注。土壤淋洗技术因其成本低、操作简单且效率高，被广泛用于永久去除污染土壤中的各种污染物，被认为是最具前景的修复技术。本文综述了土壤淋洗技术领域的最新进展，并讨论了传统淋洗剂、新型先进淋洗剂的应用、淋洗废水的循环利用以及土壤淋洗与其他修复技术的联合使用。总体而言，这些研究结果使人们对土壤淋洗技术有了全面的认识，并从科学和实际的角度提出了一些潜在的改进建议。
