Unfired aggregate as well as preparation method and application thereof
The invention provides an unfired aggregate and a preparation method and application thereof.The unfired aggregate comprises 60-120 parts of solid waste powder, 0-40 parts of alkaline residues and 5-30 parts of water, and the solid waste powder comprises one or more of tailing powder, fly ash, desulfurized gypsum, Bayer process red mud, brick slag powder and coal gangue powder; the alkaline residues comprise one or more of calcium carbonate, calcium sulfate, calcium chloride, magnesium carbonate, sodium hydroxide and calcium hydroxide, and the unfired aggregate can also be used as a water treatment filter material. The unfired aggregate provided by the invention has the beneficial effects of no toxicity, no pollution and high strength, high temperature is not needed in the preparation process, and when the unfired aggregate is used as a water treatment filter material, the unfired aggregate has good biological adhesiveness, biofilm formation performance and sewage interception capability.
本发明提供一种免烧骨料及其制备方法与应用,该免烧骨料包括固体废弃物粉料60~120份、碱渣0~40份、水5~30份,所述固体废弃物粉料包括尾矿粉、粉煤灰、脱硫石膏、拜耳法赤泥、砖渣粉、煤矸石粉中的一种或几种,所述碱渣包括碳酸钙、硫酸钙、氯化钙、碳酸镁、氢氧化钠、氢氧化钙中的一种或几种,该免烧骨料还可作为水处理滤料。本发明提供的免烧骨料具有无毒无污染、强度高的有益效果,制备过程无需高温,当其作为水处理滤料时,具有良好的生物附着性、挂膜性能和截污能力。
