汞污染土壤治理修复技术研究进展

摘要

This paper summarized the soil quality standard for Hg in China and other countries, and compared the related technical regulations for Hg-contaminated soils in China and the US. The paper also reviewed the technologies for remediation of Hg-contaminated soils, including thermal desorption, solidification/stabilization, chemical extraction and phytoremediation. Characteristics, feasibility and limits of each technology were summarized in the hope of providing a good reference for the research and engineering practice of remediation of Hg-contaminated soil in China.%总结了国内外土壤Hg环境质量标准限值,比较了中国和美国对汞污染土壤处理技术规定；在此基础上对热脱附、固化/稳定化、化学萃取和植物修复等Hg污染土壤治理修复进行了综述,总结了各技术的特点、优势和局限,可为我国汞污染土壤治理修复技术研究和工程实践提供参考.
