| 摘 要： | 从粉煤灰的污染潜势分析入手,通过复垦土壤的测试分析、淋溶试验和种植试验,揭示了粉煤灰充填复垦土壤的污染性.研究表明,粉煤灰中重金属的水溶性差,同时因pH值高,抑制了作物对高含量污染重金属的吸收;淋溶试验也表明重金属元素的淋溶性弱;温室盆栽与大田作物籽实样品分析表明,样品中重金属含量符合国家有关标准,说明尽管复垦土壤存在重金属污染,仍然可以种植某些作物. |

| Abstract: | The contamination character of filing reclaimed soil with fly ash was revealed based on the analysis of fly ashpollution potential and through the surveying analysis of reclaimed soil, leaching test and planting test. Solubility of heavymetals in fly ash was not good. and meanwhile the crop absorption of high content pollution heavy metals was restrained due to high pH value.The leaching test also showed the weak leaching ability of heavy metal elements. The analysis of crop seed sample cultivated in fields and green house pots showed that the contents of heavy metals coincided with therelated national standard, explaining that, the reclaimed land could still plant certain crops, even with the soil polluted by heavy metals. |
| Keywords: | subsided land fly ash filling reclamation heavy metal contamination soil reconstruction |
