【摘要】 针对平煤集团十二矿煤矸石不同粒径的溶出毒性实验研究,在实验室模拟控制条件下设计了两种动态淋溶实验:一是将煤矸石与粘土均匀混合;二是将煤矸石与粘土分层。通过实验分析可知,在两种控制实验中,粘土层土壤的吸附、转化作用,对控制有害元素的溶出有一定的效果,且分层处理对有害元素的溶出控制效果较好。更多还原

【Abstract】 To aim at the experimental study on the stripping toxicity of coal wastes in different particle size of No.12 Mine of Pingdingshan Coal Group, Two dynamic leach experiments were designed under simulation conditions in laboratory: one is to mix coal waste with clay uniformly, another is to divide the coal waste and clay into layers. It can be seen from the experimental analysis that in two controlled experiments, the absorption and transformation functions of clay layer have a certain effect on the control of stripping of harmful elements, and the layering treatment have the best effect on the control of stripping of harmful elements.更多还原
