重金属复合污染土体有机重构剖面构型设计

Design of organic reconstruction profile structure of composite polluted soils

在重金属复合污染区,根据自然土体剖面特点,结合复合污染土体重构目标,采用土地工程手段,经土体有机重构将重金属复合污染废弃地构造为无污染的可利用地。通过探讨复合污染土体重构剖面构型目标、剖面构型及特点、有效土层厚度和复合污染土体物理重构特征与要求等方面得出土体有机重构的设计根据,以期对重金属复合污染土地的修复治理推广应用提供帮助。

In the compound polluted area of heavy metals,according to the characteristics of natural soil profile,and the target of composite soil reconstruction,the heavy metal compound pollution wasteland was constructed as the pollution-free land by means of land engineering method.The design basis of land organic reconstruction was obtained by the target and characteristics of the profile configuration,the thickness of the effective soil layer and the characteristics and requirements of the physical reconstruction of the composite contaminated soil.In order to provide some help to the popularization and application of the remediation and management of heavy metal compound contaminated land.
