[0025] Example: Please refer to Figure 1-4 A leachate heavy metal adsorption treatment device includes an adsorption box 1, with support legs 14 fixedly connected to both ends of the bottom of the adsorption box 1, and an outlet 15 fixedly connected to the bottom of the adsorption box 1. The outlet 15 is connected to the interior of the adsorption box 1, and a pretreatment mechanism for purifying leachate is provided at the top of the adsorption box 1.
[0026] The pretreatment mechanism includes a reaction chamber 5. The top of the adsorption chamber 1 is equipped with the reaction chamber 5.

[0028] Specifically, such as Figure 1 As shown, before treating the heavy metals in the leachate, the leachate is added into the reaction tank 5 through the inlet 6, and flocculants and other purification agents are also added into the leachate through the inlet 6. The drive motor 9 is started to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the external stirring blades 7 to rotate, which can stir the leachate in the reaction tank 5 and make it react quickly with the agents, so as to quickly separate some stains and harmful substances in the leachate, thus achieving rapid purification of the leachate.
[0029] The top of the adsorption box 1 is fixedly connected to the water distribution chamber 4. The two sides of the top of the water distribution chamber 4 are fixedly connected to the filter cylinder 20. The bottom of both sides of the reaction box 5 are fixedly connected to the water guide valve 26. The top of the filter cylinder 20 is movably connected to the threaded cover 25. The two ends of the bottom of the threaded cover 25 are fixedly connected to the connecting plate 24. The bottom of the connecting plate 24 is fixedly connected to the connecting ring 22. The bottom of the connecting ring 22 is fixedly connected to the support frame 21. The inside of the support frame 21 is fixedly connected to the filter screen 23.
[0030] The connecting ring 22 is movably connected to the filter cartridge 20, and the water guide valve 26 is fixedly connected to the filter cartridge 20.
[0031] The water guide valve 26 is connected to the inside of the filter cylinder 20, and the water distribution chamber 4 is connected to the inside of the adsorption box 1.
[0032] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, after the leachate has been pretreated, the water inlet valves 26 on both sides are opened to introduce the leachate into the filter cylinder 20. While the leachate is passing through the filter cylinder 20, the filter screen 23 inside the filter cylinder 20 can automatically filter the leachate and remove the solid matter. The filtered leachate is introduced into the water distribution chamber 4, and then evenly distributed into the adsorption box 1 for adsorption treatment. After filtration, the threaded cover 25 can be rotated to drive the support frame 21 out of the filter cylinder 20, which facilitates the cleaning of the inside of the support frame 21, thus realizing automatic filtration of leachate.
[0033] Side plates 2 are movably connected to both sides of the adsorption box 1. Three sets of positioning frames 3 are fixedly connected to one side of the side plate 2.

[0036] Specifically, such as Figure 1 and Figure 2 As shown, after the leachate is introduced into the adsorption tank 1, it passes through the interior of multiple positioning frames 3. The adsorption packing 13 inside the positioning frames 3 can quickly adsorb the heavy metal substances in it. After multiple adsorptions, it is discharged through the outlet 15 at the bottom. After the treatment is completed, the fixing nut 18 can be rotated to make it detach from the fixing screw 19. Then, the side plates 2 on both sides can be pulled to remove the multiple overlapping positioning frames 3 inside the adsorption tank 1, so as to replace or clean the adsorption packing 13 inside the positioning frames 3. This realizes that the adsorption structure can be easily disassembled and reassembled for easy replacement and cleaning.
[0037] Working Principle: In use, before treating the heavy metals in the leachate, the leachate is added to the reaction tank 5 through inlet 6, along with flocculants and other purification agents. The drive motor 9 is started, driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the external stirring blades 7 to stir the leachate inside the reaction tank 5, allowing it to react quickly with the agents and rapidly separate some stains and harmful substances from the leachate. After the leachate has completed pretreatment, the water inlet valves 26 on both sides are opened to guide the leachate into the filter cylinder 20. As the leachate passes through the filter cylinder 20, the filter screen 23 inside the filter cylinder 20 automatically filters the leachate, removing solid matter. The leachate is then introduced into the interior of the water distribution chamber 4, and then evenly distributed into the interior of the adsorption tank 1 for adsorption treatment. After filtration, the threaded cover 25 can be rotated to move the support frame 21 out of the filter cylinder 20, thus facilitating the cleaning of the interior of the support frame 21. After the leachate is introduced into the adsorption tank 1, when it passes through the interior of multiple sets of positioning frames 3, the adsorption packing 13 inside the positioning frames 3 can quickly adsorb the heavy metal substances. After multiple adsorptions, it is discharged through the outlet 15 at the bottom. After treatment, the fixing nut 18 can be rotated to detach it from the outside of the fixing screw 19, and the side plates 2 on both sides can be pulled to remove the multiple sets of overlapping positioning frames 3 inside the adsorption tank 1, so as to facilitate the replacement or cleaning of the adsorption packing 13 inside the positioning frames 3.
