[0036] Specifically, the box body 100 is welded with steel plates and is used to provide a processing space for the landfill leachate concentrate. The position of the water inlet pipe 110 is higher than that of the water outlet pipe 120, and both are provided with valve switches. The debris filter bin 130 is used to filter large pieces of solid waste and particulate matter. The mixing bin 140 is used to mix the landfill leachate concentrate and the liquid medicine. The still water bin 150 is used to store the mixture of the landfill leachate concentrate and the liquid medicine after mixing. The filter frame 200 is used to block large pieces of waste or particulate matter to prevent them from entering the mixing part. When the landfill leachate concentrate is processed, the water inlet pipe 110 is used to filter large pieces of solid waste and particulate matter. After the device has been used for a period of time, the lifting mechanism 300 is started to push the filter frame 200 out to a certain height. After the debris is poured out, the lifting mechanism 300 lowers the filter frame 200 to return to its original position; the stirring mechanism 400 is used to stir the garbage leachate concentrate in the stirring chamber 140, the motor 410 drives the stirring member 420 to rotate, and the stirring member 420 drives the garbage leachate concentrate in the stirring chamber 140; the rotating cylinder 500 is used to make the garbage leachate concentrate in the stirring chamber 140 produce a variety of water flow directions; the medicine adding box 600 is used to add liquid medicine into the stirring chamber 140.
