| description | The invention relates to the technical field of solid waste resource utilization, in particular to a preparation method and application of construction waste fly ash-based ceramsite. Construction waste and fly ash are treated to prepare the construction waste/fly ash-based ceramsite, the process comprises the steps of crushing, screening, mixing, grinding and stirring, granulating, roasting and the like, the density grade of the prepared ceramsite is 500-600 grade, the apparent density is 1094.30-1358.96 kg/m < 3 >, the porosity is 53.72-64.82%, and the compressive strength is 8.87-11.9 MPa, the prepared ceramsite is used for an adsorbent in sewage treatment, and the adsorbent has the advantages that the preparation process is simple, the cost is low, and the application range is wide. According to the invention, dye and heavy metal in sewage can be effectively removed, the removal rate of dye methylene blue can reach 97.82%, and the removal rate of Pb < 2 + > can reach 99.88%. According to the method, waste |
