重金属锑污染土壤固化-稳定化修复技术研究及应用

Study and Application of Solidification-Stabilization Technology for Heavy Metal Contaminated Soil of Antimony

固化-稳定化技术具有快速、经济、有效等优点,在重金属污染土壤修复中得到了广泛应用,然而对重金属修复药剂选型及现场实际应用研究仍存在不足。本文首先利用小试实验探究了不同修复药剂对重金属锑的修复效果,筛选出适用药剂及配比,并通过上海某重金属锑污染修复工程的具体实施,总结出一套重金属污染土壤固化-稳定化施工工艺流程,为重金属锑固化-稳定化修复技术的发展及应用提供理论指导和经验借鉴。

Solidification-stabilization technology is fast,economical and effective.It has been widely used in the remediation of heavy metal contaminated soils.However,there are still many problems in the selection of heavy metal remediation agents and the practical application in the field.In this paper,we explored the remediation effect of different remediation agents on the antimony remediation using a pilot test,and find out the applicable agents and matching.Through the implementation of a heavy metal antimony pollution remediation project in Shanghai,we summarized a set of solidification-stabilization process for heavy metal contaminated soils.It can support theoretical guidance and experience for the development of heavy metal antimony solidification-stabilization technology.
