污染土壤的固化/稳定化处理技术研究进展

Advances in Solidification/Stabilization of Contaminated Soils

固化/稳定化技术具有快速、有效、经济等特点,广泛应用于各类危险废物的处理,但土壤方面的应用还比较匮乏。本文介绍了近年来污染土壤固化/稳定化研究和应用的现状,概括了从实验室研究、现场试验到处理工程的流程,重点对常见固化系统、主要影响因素、处理效果评价、固化机理研究和修复工程的实施等方面的研究进展加以总结,并对其发展趋势加以展望。

Solidification/stabilization has been widely used to treat a variety of hazardous wastes due to its quickness, high-efficiency and cost-effectiveness, but its applications in soils are relatively rare. The research and application of solidification/stabilization in contaminated soils was reviewed in this paper, and the implementation processes from laboratory study, site trial to in-situ treatment projects were summarized. Frequently employed binder systems, influential factors and evaluation methods for treatment performance, solidification/stabilization mechanisms, and typical engineering application cases were emphasized. The technical trends of soil solidification/stabilization were then prospected in the last part of the paper.
