摘要(Abstract)：

为了研究电镀污泥的资源化利用，以电镀污泥作晶核剂，采用前置热处理和熔融法制备了电镀污泥基微晶玻璃，以电镀污泥中Cr （VI）的固化浸出效果为考察对象，筛选出较优的电镀污泥添加比例，通过热重-差热仪（TG-DSC）研究了含电镀污泥基础玻璃适宜的核化温度和晶化温度，并通过X射线衍射（XRD）和扫描电子显微镜（SEM）对制得的电镀污泥基微晶玻璃结构进行了表征。实验结果表明：在电镀污泥添加量为30%时，Cr （Ⅵ）的固化浸出（1.10 mg·L^-1）较低，说明玻璃对于电镀污泥中重金属具有较好固化效果。XRD表明在晶化温度720~760℃，可以得到稳定晶相的电镀污泥基微晶玻璃，SEM表明电镀污泥被包埋在微晶玻璃中形成致密结构。
