摘要
研究了含钒石煤烧渣稳定化处理的一种有效方法。利用石灰为稳定剂与烧渣相混合进行稳定化处理,渣中的水溶态钒转化为钒酸钙沉淀而降低毒性,浸出试验表明,水中钒浓度<5 mg/L,并且具有长期的稳定性,无二次污染。
An effective method of stabilizing bone coal vanadium mine cinder with lime was investigated . The toxicity of the treated cinder was greatly reduced by way of water- soluble vsnsdium changed into calcium vanadate, the soaking experimental results showed that the concentration d water, soluble vanadium 〈 5mg/L, and stabilization is longeval, there is not qusdratic pollution.
