The sludge lifting and drying treatment area 3 drains and dries the sludge precipitated in the sewage treatment area 5, so that the water content of the sludge after drainage and drying is not higher than 65% and is discharged. The sewage treatment area 4 purifies the waste gas in the sewage treatment area 5, so that the bacteria and virus content of the discharged gas is lower than 0.1% and is discharged.

[0044] Preferably, the domestic waste delivery area 1 is provided with an induction valve device, a garbage compression device and a garbage discharge device; the induction valve device includes a first sensor 11, an electric telescopic rod 12, and a movable baffle 13. The first sensor 11 is provided on the upper panel of the domestic waste delivery area and is used to sense the position of the garbage delivery vehicle. Its sensing method includes infrared sensing and QR code recognition. The first sensor 11 is connected to the electric telescopic rod 12 through a wire to control the extension and contraction of the electric telescopic rod. The electric telescopic rod 12 is fixedly mounted on the upper panel of the domestic waste delivery area, and the telescopic end of the electric telescopic rod 12 is in contact with the movable baffle 13. The baffle 13 is connected, and the movable baffle 13 is arranged directly above the garbage delivery port 17, and the garbage delivery port 17 is arranged on the upper panel of the domestic garbage delivery area; when in use, its control principle is equivalent to an air switch. When the sensor 11 control circuit is connected, the electric telescopic rod 12 is energized, driving the movable baffle 13 to move left and right. When the sensor 11 control circuit is disconnected, the electric telescopic rod 12 is not energized, and the movable baffle 13 does not move. In order to enable the movable baffle 13 to completely cover the garbage delivery port 17 and prevent the accumulated odor from leaking, the area of ​​the movable baffle 13 is larger than the area of ​​the garbage delivery port 17.

[0045] Preferably, the garbage compression device includes a first hydraulic telescopic rod 14 and a first compression plate 18 symmetrically arranged at the front and rear ends of the inner cavity of the domestic garbage delivery area. The bases of the first hydraulic telescopic rod 14 are respectively installed on the inner side walls of the left and right ends of the inner cavity of the domestic garbage delivery area, and the front end of the piston rod of the hydraulic telescopic rod 14 is connected to the first compression plate 18. When in use, by pressurizing the hydraulic telescopic rod 14, the two symmetrically arranged first compression plates 18 move toward each other, compressing the medical garbage, so that the medical garbage is formed into a compressed garbage block under the pressure of the two first compression plates 18. In order to enable the first compression plate 18 provided on the inner wall of the left end of the domestic waste delivery area to push out the garbage block, the first compression plate 18 provided on the inner wall of the right end of the domestic waste delivery area is not working, the two hydraulic telescopic rods 14 are controlled by two different air pressure control valves, so that the two hydraulic telescopic rods 14 can not work at the same time; the garbage discharge device includes a movable bottom plate 16 provided on the right side of the first lower bottom plate 15 of the domestic waste delivery area, and the movable bottom plate 16 moves left and right under the action of the telescopic assembly; the telescopic assembly includes a movable bottom plate 16 provided on the movable bottom plate 16 The locking head 161, the rolling pulley 162, the connecting plate 163 and the first motor 165, the screw rod 164, the locking groove 153 and the sliding groove 152 arranged on the first lower bottom plate 15 are provided on the left side of the movable bottom plate 16. The locking head 161 is provided with a locking groove 1611. A lock core 166 is installed in the locking groove 153. A locking spring 167 is provided at the bottom of the lock core 166. The tip of the lock core 166 is provided with an arc-shaped locking protrusion 1661 for use with the locking groove 1611, and a locking spring 167 is provided on the right side of the lock core 166. There is an L-shaped unlocking key 168. When locked, the locking protrusion 1661 is engaged in the locking groove 1611 to lock the position of the movable base plate 16. When the movable base plate 16 needs to be opened, the staff can move the L-shaped unlocking key 168 manually or electrically to retract the locking protrusion 1661 from the locking groove 1611. At this time, the locking structure loses its constraint on the movable base plate 16; the rolling pulleys 162 are set on the front and rear sides of the movable base plate 16. The rolling pulleys 162 cooperate with the sliding grooves 152 to slide left and right along the sliding grooves 152;The connecting plate 163 is arranged on the rear side of the movable bottom plate 16, and an internal thread and an external thread on the screw rod 164 are provided on the connecting plate 163. The screw rod 164 is connected to the power output end of the first motor 165 through a spline sleeve. Therefore, when it is necessary to open the movable bottom plate 16 to clean the garbage blocks in the domestic garbage disposal area 1, the first compression plate 18 is first used to push the garbage blocks to the upper side panel of the movable bottom plate 16, and then the L-shaped unlocking key 168 is manually or electrically pushed to retract the locking protrusion 1661 from the locking groove 1611. At this point, the locking structure loses its restraint on the movable bottom plate 16. The first motor switch is then turned on, causing the first motor 165 to rotate forward, causing the movable bottom plate 16 to move rightward under the meshing force of the teeth, causing the garbage block to fall and be transported by a garbage truck. After the garbage block is transported away, the first motor switch is adjusted, causing the first motor 165 to rotate in the reverse direction, thereby rotating the movable bottom plate 16 back. The locking protrusion 1661 reengages the locking groove 1611, locking the movable bottom plate 16 in place, and the thrown-in garbage can be compressed and packaged again.
