Storage structure of heavy metal contaminated soil

摘要

To effectively enhance contact frequency between an adsorbent and a heavy metal in an adsorption layer while making reworkability easy.SOLUTION: A storage structure has a banking body part 1A in which at least a water shielding layer 2 and a polluted soil layer 4 containing a heavy metal are laminated from a foundation side G, and a leachate flowing down on an upper surface of the water shielding layer 3 from the polluted soil layer 4 is introduced to a side surface 2A of the water shielding layer 2, and an adsorption layer 6 which is arranged in contact with at least the side surface 2A of the water shielding layer 2, and in which the leachate leaching from the banking body part 1A is distributed and an adsorbent adsorbing the heavy metal contained in the leachate is mixed.SELECTED DRAWING: Figure 1
