Solid-liquid mixed material treatment method and device

The invention discloses a solid-liquid mixed material treatment method and device. According to the method, an appropriate separating agent is selected according to the characteristics of a to-be-treated material; density of the separating agent is between densities of to-be-separated solid-phase and liquid-phase substances in the material; the separating agent 20%-20 times of the mass of the material is added to the to-be-treated material, and a separating agent layer is formed between the solid phase and the liquid phase; a centrifugal machine is adopted to perform centrifugal separation; the solid-phase material obtained after separation is dried, the liquid-phase material obtained after separation is evaporated, and the separating agent is recycled. The treatment device comprises a stirring tank, a mixed liquid transfer pump, the centrifugal machine, a condensing device, an evaporator and a drying device. The method has the advantages of being low in treatment energy consumption, good in solid-liquid sepa
