固体废弃物稳定化修复污染土壤的研究进展

Research Progress in Stabilized Remediation of Contaminated Soil by Solid Waste

土壤污染是当前环境治理的重中之重,关乎我国国家发展长治稳定,也是人民安全的基本保障。作为重金属污染土壤的主要修复手段之一,固体稳定化土壤修复技术以固体废弃物资源化和土壤原位绿色化修复为基础,大幅的固化土壤中重金属,已得到广泛的发展。本文概述了其种类、优化措施以及尚待解决的关键问题,对当前国内外固体废物土壤稳定化技术进行系统化总结,为我国重金属污染土壤的治理指明方向,提出了固废资源化与重金属土壤修复的复合绿色化发展。

Soil pollution is the top priority of current environmental governance, which is related to the long-term development and stability of the country, and is also the basic guarantee for the safety of the people. As one of the main remediation methods for heavy metal contaminated soil,stabilized technology has been widely developed based on the recycling of solid waste and the in-situ green remediation of soil.This paper summarized the types, optimization methods, and key problems to be solved, systematically summarize the current domestic and foreign solid waste soil stabilization technologies, provide the direction for the treatment of heavy metal contaminated soil in China and proposed a composite green development of solid waste recycling and heavy metal soil remediation method.
