Title:
The heavy metal adsorption layer used for an adsorption layer construction method
Document Type and Number:
Japanese Patent JP6199078
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a heavy metal adsorption layer which exhibits high effectiveness, when used for adsorbing/removing heavy metals, which is suitable to treatment of an object that is to be treated, is generated in large quantities and contains heavy metals and which can allow a treatment cost of the object to be treated to be made lower.SOLUTION: The heavy metal adsorption layer for adsorption layer construction methods has the simply-measured water permeability coefficient equal to or lower than 1.0×10m/s. The simply-measured water permeability coefficient is preferably equal to or lower than 5.0×10m/s, more preferably equal to or lower than 1.0×10m/s and furthermore preferably equal to or lower than 5.0×10m/s. The compaction degree of the heavy metal adsorption layer is preferably 80% or higher.
