Pollutant adsorption sheet and pollutant adsorption method using the sheet

摘要

PROBLEM TO BE SOLVED: To effectively capture pollutants such as heavy soils generated from excavated residual soil, sludge and drainage, such as excavation excavation generated in construction and civil engineering work, lightweight and excellent in workability and durability, pollution Provided are a substance adsorption sheet and a method for adsorbing contaminants such as heavy metals using the adsorption sheet. SOLUTION: The pollutant adsorption sheet is a pollutant adsorption sheet for trapping pollutants leached from the residual soil containing the pollutant, construction soil, sludge or drainage, and the pollutant adsorption sheet comprises a nonwoven fabric and heavy metal. An adsorbent that adsorbs is carried, the nonwoven fabric has a unit area of 10 to 600 g/m 2, the adsorbent has a contaminant adsorption sheet of 10 to 5000 g/m 2, and a water permeability coefficient of 10 −5 cm/m 2. It is characterized by being s or more. [Selection diagram] Figure 2
