| 内容記述 | The purpose of this study was to evaluate a leakage restraint effect of steel slag used for intermediate cover in a final disposal site. Advection diffusion parameters such as diffusion coefficient(D), volumetric water content(θ) and distribution coefficient (Kd) were determined by column experiments and batch adsorption experiments. Lead concentration leaked from slag layer was predicted based on the two lead elution scenarios in which a distribution of lead concentration eluted from fly ash was rectangle (Scenario 1) and triangle (Scenario 2). In Scenario 1, an inflow lead concentration was constant until available lead washed out, and then the inflow lead concentration became zero. In Scenario 2, an inflow lead concentration increased at a constant rate until reached the maximum concentration, and then the inflow lead concentration decreased at a constant rate. The observed lead concentration from a bottom of the column agreed with the calculated lead concentration using a Kd of 63.8 L/kg obtained from column experiments more than that using a Kd of 11.5 L/kg obtained from batch experiments. One of the reasons that the Kd obtained from column experiments was larger than the Kd obtained from batch experiments might be that the slag used in column experiments contacted continuously with lead solution for about 50 days. In the two lead elution scenarios, in the considered range of infiltration flow rate into landfill layer, inflow lead concentration in Scenario 1 and the maximum inflow lead concentration in Scenario 2, the slag used in this study could not be suppress leachate lead concentration below the Japanese effluent standard. In the two scenarios, it was found that setting Kd to 95,700L/kg could be suppressed leachate lead concentration below the Japanese effluent standard. | |||||
