水库淤泥烧制后重金属稳定性试验研究

摘要

The secondary pollution of heavy metal in reservoir silt is the key factor to restrict its reclamation. The result shows that, after sintering, the formation of heavy metal in reservoir silt is transformed, and the stability of heavy metal in reservoir silt after sintering is improved. Thus, the heavy metal is difficult to dissolve out or otherwise dissolve at a minor amount, so that the secondary pollution can be avoided.%　　水库淤泥中重金属的二次污染是制约其资源化利用的关键问题。研究表明，经过烧制后，水库淤泥中重金属形态发生转化，提高了水库淤泥烧制产品中重金属的稳定性，重金属不易溶出，且溶出量微少，避免了二次污染的产生。
