我国砒霜厂场地污染现状及其治理研究进展

The pollution status and research progress of remediation for arsenic factory sites in China

砒霜厂是我国一类典型的重金属复合污染场地。介绍了国内砒霜厂遗留场地的形成背景和污染现状,对物理阻隔、固化/稳定化、生态修复三类主要治理技术的基本原理和特点进行了综述,并重点阐述了固化/稳定化材料的种类及其应用现状,总结了砒霜厂污染场地治理的典型工程案例,分析与展望了砒霜厂污染场地治理技术的发展方向,旨在为砒霜厂污染场地的修复和管理提供参考。

Arsenic factory is a typical heavy metal combined contamination site in China.In this paper,the formation background and pollution status of the sites left behind by the arsenic factory in China was introduced,the basic principles and characteristics of the three main treatment technologies of physical barrier,solidification/stabilization and ecological restoration were reviewed,and the types of solidification/stabilization materials and their applications were emphasized.Besides,some typical engineering cases were also expounded and the development direction of treatment technology was further analyzed and prospected to provide reference for the remediation and management of arsenic factory contaminated sites.
