Title:
CONTROL METHOD FOR COMPOSITE METAL IONS IN SOLID WASTE LANDFILL
Document Type and Number:
WIPO Patent Application WO/2024/036966
Kind Code:
A1
Abstract:
A control method for composite metal ions in a solid waste landfill, relating to the field of metal pollution treatment in solid waste landfills. Permeable adsorption walls capable of adsorbing harmful substances in leachate are built around a solid waste landfill. If the solid waste landfill is arranged against a mountain, there is only a need to build a permeable adsorption wall on the outer side surface of the solid waste landfill not surrounded by the mountain, and if groundwater exists beneath the solid waste landfill, the built permeable adsorption wall needs to extend underground to an underground aquiclude so as to prevent leachate in the solid waste landfill from flowing out along with the groundwater. The permeable adsorption wall sequentially consists of an inherent soil layer, an inherent soil layer and attapulgite mixed layer, an inherent soil layer and attapulgite @ manganese dioxide mixed layer, an inherent soil layer and attapulgite @ copper sulfide mixed layer, and an inherent soil layer.
