The reciprocating screw 12 passes through the slide groove 10 and penetrates the slider 8. A short shaft 14 is provided in the slider 8 to form a sliding connection with the bidirectional thread groove. The driving member drives the slider 8 to reciprocate in the slide groove 10 by driving the bidirectional screw to rotate. The rotation of the reciprocating screw 12 can drive the slider 8 to continuously reciprocate, thereby driving the purification aeration pipe 9 to reciprocate in the leachate.

One end of the second channel 22 is connected to the purification cavity, and the other end extends in the slider 8 (the trajectory needs to be staggered from the connection between the slider 8 and the reciprocating screw 12). It should be noted that: the chute 10 is located at the bottom of the slider 8 and is formed with a pipe placement area 26 for connecting the first hose 24 and the second hose 25 to the docking pipe 23 or placing them during the movement of the slider 8.

[0035] Specifically, the box body 1 is provided with a first valve port 28 and a second valve port 29 at the bottom of the stirring frame 5. The other end of each first hose 24 connected to the first channel 21 passes through the guide rail 7 and is connected to the first valve port 28; the other end of each second hose 25 connected to the second channel 22 passes through the guide rail 7 and is connected to the second valve port 29.

[0037] Specifically, a flared opening 30 is provided at the top of the purification core 91 .

[0038] A specific application example of this embodiment is:

[0039] When the device is in use, the staff first injects the landfill leachate into the box body 1 (injected through the injection pipe on the box body 1), and after injecting a certain amount of landfill leachate (preferably the aeration port 18 at the upper end of the grinding aeration pipe 92), inject an equivalent amount of deodorant again. After that, the staff controls the ozone generator 4, the motor 6 and the fan 27 to operate synchronously through the control switch group (the control switch group is connected to the external power supply, and the ozone generator 4, the motor 6 and the fan 27 are all electrically connected to the control switch group). The motor 6 starts to drive the stirring frame 5 to stir the leachate. At the same time, the rotation of the stirring frame 5 will cause the first bevel gear 15 to drive the second bevel gear 16 to rotate. The rotation of the second bevel gear 16 will drive each set of reciprocating screws 12 to rotate. The rotation of the reciprocating screw 12 will drive the slider 8 to slide on the guide rail 7, thereby bringing The dynamic purification aeration pipe 9 moves; at the same time, the ozone generator 4 operates to generate ozone and injects it into the annular cavity 17 through the first hose 24, and exposes the ozone through the aeration port 18, thereby reacting with the landfill leachate, thereby achieving the purpose of purifying the landfill leachate. As the stirring rack 5 stirs the leachate and the purification aeration pipe 9 continuously moves in the leachate, the deodorant and the landfill leachate will be more evenly and fully mixed, thereby reducing the time of the deodorization reaction. The odor generated by the landfill leachate will pass through the vertically arranged purification core 91 in turn. The volcanic rock honeycomb panel 19 and the activated carbon filler 20 inside the purification core 91 will deodorize, filter and adsorb the gas, thereby achieving a high-efficiency deodorization effect. The observation plate 2 enables the staff to intuitively observe the degree of deodorization and purification of the landfill leachate.
