电厂粉煤灰场对土壤及浅层地下水污染的试验研究

The Study on Pollution of Ash Fields on the Soil and Shallow Groundwater

以太原二电厂粉煤灰场为例,通过淋溶试验来模拟大气降水对粉煤灰的淋溶过程以及淋溶液对土壤和浅层地下水水质的影响,说明其影响因素主要取决于排灰场土壤类型及灰水污染物的种类和浓度。从模拟试验结果可知,土壤对F-,As等污染物的吸附能力较强。

On the basis of the ash field in second power plant of Taiyuan,we study the fly ash stored effect on the soil and shallow groundwater,which depends mainly on the types of soil in the area,the types and concentrations of pollutants contained.The leaching test have shown that the adsorption of the soil to F -,As is very powerful.
