STORAGE STRUCTURE OF HEAVY METAL POLLUTED SOIL
PROBLEM TO BE SOLVED: To increase the adsorption capacity of heavy metals in an adsorption layer and to suppress the heavy metals without providing an adsorption apparatus.SOLUTION: Provided is a filling 1 including: a pollution soil layer 4 formed by pollution soil including arsenic; a water shielding layer 2 provided at the part lower than the pollution soil layer 4 in a shape same as the lower face of the pollution soil layer in a plane view and shielding leachate from the pollution soil layer 4; and an adsorption layer 3 provided between the pollution soil layer 4 and the water shielding layer 2 in a shape same as the lower face of the pollution soil layer 4 in a plane view and adsorbing the arsenic eluted in the leachate.SELECTED DRAWING: Figure 1
【課題】吸着層における重金属の吸着能力を高め、吸着装置を設けることなく重金属の拡散を抑制する。【解決手段】盛土１は、砒素が含まれる汚染土によって形成される汚染土層４と、汚染土層４よりも下方に、平面視において汚染土層の下面と同じ形状に設けられ、汚染土層４からの浸出水を遮る遮水層２と、汚染土層４と遮水層２の間に、平面視において汚染土層４の下面と同じ形状に設けられ、浸出水に溶出された砒素を吸着する吸着層３とを備える。【選択図】図１
