Fly ash-based porous defluorination material as well as preparation method and application thereof
The invention discloses a fly ash-based porous defluorination material as well as a preparation method and application thereof. The porous defluorination material comprises the raw materials by weight: 20-40 parts of fly ash, 20-50 parts of calcined coal gangue, 0-20 parts of a fluorine ion adsorbent, 50-200 parts of water glass, 1-3 parts of a foaming agent and 0.1-0.2 part of a foam stabilizer.The preparation method of the fly ash-based porous defluorination material comprises the steps: a raw material mixing step: uniformly mixing fly ash, calcined coal gangue, the fluorine ion adsorbent and the foam stabilizer according to the ratio, and then adding the mixture into water glass to obtain a mixed material; a stirring step: stirring the mixed material for the first time, then adding hydrogen peroxide, and stirring for the second time to obtain mixed slurry; and a molding and curing step: carrying out molding treatment on the mixed slurry, and then curing to obtain the fly ash-basedporous defluorination material. The preparation method provided by the invention can achieve the purpose of treating waste with waste, and has an excellent defluorination effect.
