| 摘 要： | 以太原二电厂阳坡沟粉煤灰场为例,建立灰水中污染物在土壤包气带的垂直迁移规律模型。通过数值计算可知,灰水污染物F-和As垂直入渗到达含水层中的浓度与包气带土壤渗透系数、吸附分配系数的关系均呈线性关系,灰水污染物F-到达含水层时的浓度与包气带土壤厚度的关系呈线性关系,污染物As的浓度与包气带土壤厚度的关系呈多项式曲线关系。

| Abstract: | Taking the fly ash field in the second power plant of Taiyuan as a case,a vertical transfer model of pollutants in fly ash water in aeration zone of soil was established.By numerical method,it is concluded that the concentration of F-and As percolating into the aquifer varies linearly with penetration coefficient and adsorbed distribution coefficient of soil.The concentration of F-varies linearly with the soil depth of the aeration zone of soil,while that of As is of a polynomial relationship with the depth. |
