Method for preparing ceramsite filter material by synergistically utilizing solid waste
The invention discloses a method for preparing a ceramsite filter material by synergistically utilizing solid wastes, and solves the technical problems that in the prior art, the doping amount of the solid wastes is small, and high-alumina fly ash is not adopted for preparing a high-performance ceramsite filter material. The method comprises the following treatment steps: S1, raw material pretreatment: taking high-alumina fly ash, red mud and sludge as raw materials for preparing the ceramsite filter material, airing the red mud and the sludge, and grinding to obtain red mud and sludge powder; s2, proportioning 65%-80% of high-alumina fly ash, 5%-25% of red mud and 5%-20% of sludge, and uniformly stirring the prepared mixture in a mixer; and S3, spraying water and granulating to prepare the ceramsite filter material raw material balls. The prepared filter material is high in strength, high in void ratio, large in specific surface area, high in acid and alkali corrosion resistance, basically insoluble in acid and alkali solutions and reusable, all indexes such as the mud content of the filter material meet the standard requirements of CJ/T299-2008 Artificial Ceramsite Filter Material for Water Treatment, and the filter material is a high-quality filter material product.
本发明公开了一种固废协同利用制备陶粒滤料的方法，解决了现有技术中的固废掺加量少、未采用高铝粉煤灰，制备高性能陶粒滤料的技术问题。它包括下述的处理步骤：S1原料预处理，陶粒滤料的制备原料为高铝粉煤灰、赤泥和污泥，将赤泥和污泥进行晾晒处理后，粉磨得到赤泥和污泥粉末；S2按照65%～80%高铝粉煤灰、5%～25%赤泥和5%～20%污泥进行配料，并将配制好的混合物料放入混料机搅拌均匀；S3喷水造粒，制备成陶粒滤料生料球。本发明的制备出的滤料强度高、空隙率高、比表面积大，耐酸碱腐蚀性强，基本不溶于酸碱溶液，可重复利用，滤料含泥量等各项指标均满足CJ/T299‑2008《水处理用人工陶粒滤料》标准要求，是优质的滤料产品。
