| 中文摘要: |
| 火力发电厂灰场的粉场灰对土壤和浅层地下水均有影响，其对浅层地下水影响的大小，主要取决于排灰场土壤的类型及污染物的种类和浓度，从模拟试验结果可知，土壤对砷，氮，六价铬的吸附能力远小于汞和铅。 |
| 英文摘要: |
| The ash residue from a steam power plant is usually transported hydrau lically to the ash disposal area through pipelines. Some of the pollutants contained in the ash residue will inevitably dissolve in the effluent water. Therefore, the ash stored there has an effect on the soil and shallow groundwater, which depends mainly on the types of soil in t he area, the types and concentrations of pollutants contained. In this paper, experiments wer e carried out to investigate the influence of the effluent water in the ash disposal area for a steam power plant on the soil and shallow groundwater in the area. The concentrations of som e pollutants, inclusive of heavy metals Pb, Hg, As, and Cr etc., contained in the effluent wat er and soil were measured, and conclusions were drawn for the effect of the ash disposal are a for the steam power plant on the soil and shallow groundwater. |
