摘要
研究铁矾渣与石灰和水泥的反应产物及水泥对重金属离子的固化能力。结果表明,添加石灰和水泥都可将铁矾渣完全分解,分解产物也为Fe_3O_4和石膏。用水泥对铁矾渣进行固化处理,固化体的浸出毒性符合国家标准要求。
The reaction product of jarosite slag with lime and cement,and the solidification ability of cement for heavy metal ions are investigated. The results indicate that the jarosite slag is decomposed by addition of lime and cement,and the products are Fe3O4 and gypsum. The leaching toxicity of the solidified body of jarosite slag by using cement is satisfied with the national standards.
