Abstract: Based on the introduction of collaborative disposal technology of solid waste and polluted soil preparation ceramic particles at home and abroad, and the research progress of ceramic particle technology in China and the collaborative disposal technology of solid waste and polluted soil preparation ceramic particles were summarized. Through a comparison of domestic and foreign scholars in the preparation of ceramic particles from solid waste and polluted soil, it was found that using polluted soil and solid waste as raw materials to produce ceramic particles is an upgrade and improvement on the basis of the original process. According to the existing research, the maximum amount of contaminated soil or solid waste added could reach to 40%, and the ceramic particles prepared by this method basically meet the national standards in terms of compressive strength, water absorption, bulk density, apparent density, and other ceramic particle quality. In terms of pollutant treatment, the solidification effect of heavy metals was relatively excellent, up to 99.80%. Due to the high temperature conditions required for the preparation of ceramic particles, secondary pollution may occur during the treatment process. Therefore, in practical applications, it is necessary to add exhaust gas treatment devices to meet the national emission standards. The collaborative disposal technology of solid waste and polluted soil preparation with ceramic particles could not only effectively treat pollutants, but also could achieve resource reuse and generate considerable economic benefits.
