8. The device for treating paper medical waste according to claim 1, characterized in that: The crushing blade group comprises a blade arranged in the impregnation chamber and a blade driving motor arranged on the main machine, and the output end of the blade driving motor is transmission-connected with the blade.

9. The device for treating paper medical waste according to claim 9, characterized in that: When the impregnator is in a normal placement state, the rotation centerline of the blade is inclined relative to the horizontal direction, the blade comprises a connecting piece and at least two blade pieces integrally arranged outside the connecting piece, the blade piece is bent in the axial direction relative to the connecting piece, and the bending directions of two adjacent blade pieces are opposite; and / or, The output end of the blade drive motor is connected to the blade through a coupling assembly. The coupling assembly and / or the blade drive motor is provided with a water cooling mechanism. The water cooling mechanism includes a water inlet and a water outlet provided on the coupling assembly and / or the blade drive motor, and a water channel connecting the water inlet and the water outlet provided in the coupling assembly and / or the blade drive motor.

10. The device for treating paper medical waste according to claim 1, characterized in that: The sewage discharge mechanism includes an inflatable sealing head that abuts against the sewage discharge port, and an inflation or exhaust port for inflating or exhausting the sealing head. Inflating the sealing head through the inflation or exhaust port can make the sealing head approach and block the sewage discharge port, and exhausting the sealing head through the inflation or exhaust port can make the sealing head move away from and open the sewage discharge port.
