Method for preparing industrial solid waste filler and application of industrial solid waste filler
The invention discloses a method for preparing an industrial solid waste filler and application of the industrial solid waste filler. The method comprises the steps of pretreating industrial solid wastes to obtain industrial solid waste powder; then mixing the industrial solid waste powder with deionized water to obtain a water-slurry mixture; separating and drying solid matters in the water-slurry mixture to obtain a solid material; roasting the solid material, cooling the product, and grinding the solid into powder; and mixing the powder with Portland cement, mixing the mixed powder, deionized water and hydrogen peroxide, foaming at room temperature, and naturally air-drying at room temperature so as to prepare the industrial solid waste filler material. According to the invention, cement is combined with the solid waste filler, so that foamed concrete with an adsorption effect can be prepared, the adsorption effect is effectively combined with the characteristics of concrete, a relatively good phosphorus and antimony adsorption removal effect is shown, the cost is low, the purpose of treating waste with waste is achieved, and the solid waste filler has important industrial value.
本发明公开了一种工业固体废物填充剂的方法及其应用，先进行工业固体废物的预处理，得到工业固体废物粉末；然后工业固体废物粉末和去离子水进行混合，得到水浆混合物；再将水浆混合物中的固形物进行分离，干燥，得到固体材料；然后将固体材料进行焙烧，产物冷却后的固体研磨成粉末；再将粉末与硅酸盐水泥进行混合，再将混合粉末、去离子水和过氧化氢进行混合，在室温下发泡并在室温下自然风干，从而制得工业固体废物填充剂材料。本发明将水泥与此种固体废物填充剂结合，可制得到具有吸附作用的发泡混凝土，有效得将吸附作用与混凝土的特点相结合，展示出了较好的吸附除磷除锑的效果，并且成本低廉，起到了以废治废的目的，具有重要的产业价值。
