Abstract: A device comprises a raw material conveyor, a raw material mixer, a liquid waste conveying pipeline, an additive tank, a powder waste conveyor, an output pump, a liquid supply pump, a liquid supply manifold, an output manifold, a mixed liquid conveying pipeline, a high-pressure injection pump, a high-pressure pipeline, and a wellhead sealing device. The method includes: drilling a well; forming a fracture in the granite stratum; preparing a raw material; and injecting, by using a disposal device, a sand-carrying feed liquid from a high-pressure injection pump into the fracture of the underground granite stratum, so as to perform solidification. The method has low cost, high disposal efficiency, simple device structure, high usability, safety and reliability, and an effective reduction in nuclear waste contamination and hazards to the environment.
