Method for preparing solid waste cementing material by using dry desulfurization ash and solid waste cementing material
The invention relates to the fields of solid waste pollution absorption disposal, resource recycling and the like, in particular to a method for preparing a solid waste cementing material by using dry desulfurization ash and the solid waste cementing material. The method for preparing the solid waste cementing material by using the dry desulfurization ash comprises the following steps: step A, washing the dry desulfurization ash with water; step B, drying the washed dry desulfurization ash; step C, stirring and mixing the dried dry desulfurization ash and an additive A to obtain an exciting agent; step D, adding a third component into the exciting agent, and stirring and mixing to obtain a solid waste cementing material; wherein the third component is one or more of the following materials: slag, steel slag, fly ash, cement and volcanic ash. According to the invention, resource utilization of various solid wastes is realized, the environmental protection pressure of steel, coking and other enterprises is reduced, and economic benefits can be brought to the enterprises.
本发明提供了涉及固体废物污染消纳处置、资源循环利用等领域，尤其涉及一种利用干法脱硫灰制备固废胶凝材料的方法，固废胶凝材料。本发明利用干法脱硫灰制备固废胶凝材料的方法包括：步骤A，将干法脱硫灰进行水洗；步骤B，将水洗后的干法脱硫灰进行干燥；步骤C，将干燥后的干法脱硫灰与添加剂A搅拌混合，得到激发剂；步骤D，在激发剂中加入第三组分，搅拌混合，得到固废胶凝材料；其中，第三组分为以下材料中的一种或多种：矿渣、钢渣、粉煤灰、水泥、火山灰。本发明实现了各种固体废弃物的资源化利用，减轻了钢铁、焦化等企业的环保压力，同时还能为企业带来经济效益。
