[0002] Landfill leachate treatment is an important environmental issue, involving the operation and management of urban landfills and environmental protection. The technical approach to leachate treatment includes source reduction, process control, end-of-pipe treatment, and the combination of technical and management measures, as well as the combination of practicality and economy, to promote technological development.

[0022] Please see Figure 1-4 This utility model provides a technical solution: a landfill leachate full-volume treatment system, including a support base 1, a landfill treatment cylinder 2, an odor treatment cylinder 3, and a collection tank 4. The landfill treatment cylinder 2 and the odor treatment cylinder 3 are both fixedly installed on the upper end face of the support base 1, and the collection tank 4 is fixedly installed inside the support base 1. A filter plate 5 is provided inside the landfill treatment cylinder 2 for limited movement.

[0023] Specifically, a fixing ring 17 is fixedly installed inside the garbage disposal bin 2, and multiple springs 18 are evenly fixedly installed on the lower end face of the fixing ring 17. The other end of the springs 18 is fixedly connected to the upper end face of the filter plate 5.

[0024] The outer wall of the filter plate 5 slides in contact with the inner wall of the waste disposal cylinder 2.

[0025] The top of the waste disposal bin 2 is fixedly installed with a liquid inlet pipe 6, and a turbine fan blade 7 is rotatably installed inside the liquid inlet pipe 6.

[0026] A linkage assembly is provided between the turbine fan blade 7 and the filter plate 5.

[0027] The linkage assembly includes a moving rod 8, a first protrusion 9, a fixing plate 10, and a second protrusion 11.

[0028] The top limit rotation of the moving rod 8 is located inside the inlet pipe 6.

[0029] Specifically, a limiting bracket 12 is fixedly installed inside the liquid inlet pipe 6. The limiting bracket 12 is rotatably connected to the moving rod 8. Limiting rings are fixedly connected to the upper and lower sides of the limiting bracket 12 on the outer side of the moving rod 8.

[0030] The top of the movable rod 8 is fixedly connected to the turbine blade 7. The movable rod 8 is movably engaged with the filter plate 5.

[0031] Specifically, a through hole is provided at the center of the filter plate 5, and the moving rod 8 extends through the through hole to the bottom of the filter plate 5.

[0032] The lower end face of the filter plate 5 is uniformly fixed with a plurality of first protrusions 9 in a ring shape. The bottom end of the moving rod 8 is fixed with a fixing plate 10. The upper end face of the fixing plate 10 is fixed with second protrusions 11 on both sides. The second protrusions 11 slide with the first protrusions 9.

[0033] A funnel 13 is fixedly installed at the bottom of the inside of the garbage disposal bin 2. A conduit 14 is fixedly connected to the bottom of the funnel 13, and the other end of the conduit 14 extends into the inside of the collection tank 4.

[0034] The odor treatment cylinder 3 and the collection tank 4 are connected by a connecting pipe, which is equipped with an expansion section. The expansion section is an existing structure, specifically a hollow spherical structure.

[0035] The odor treatment cylinder 3 is fixedly mounted on the upper surface of the support base 1 by a bracket. A multi-layer molecular sieve 15 is fixedly installed inside the odor treatment cylinder 3. The multi-layer molecular sieve 15 includes an activated carbon adsorption layer and a zeolite adsorption layer.

[0036] An exhaust pipe 16 is fixedly installed at the top of the odor treatment cylinder 3, and a gaseous hazardous substance monitoring device is installed at the top of the exhaust pipe 16. An axial flow fan is installed inside the exhaust pipe 16. After the leachate is filtered by the filter plate 5, it enters the collection tank 4 through the funnel 13 and the conduit 14. Subsequently, odorous gas is generated. At this time, the axial flow fan located inside the exhaust pipe 16 is turned on to draw the gas in the odor treatment cylinder 3 to the outside, so that the gas pressure in the odor treatment cylinder 3 decreases. Then, the odorous gas in the collection tank 4 enters the odor treatment cylinder 3 through the connecting pipe. The odorous gas then passes through multiple molecular sieves 15. The multiple molecular sieves 15 filter and purify the odorous gas, so that the odor in the gas is removed, meets the emission standards, and avoids environmental pollution.

[0037] Working principle:

[0038] In use, the leachate is discharged into the interior of the waste treatment cylinder 2 through the inlet pipe 6. When the leachate passes through the turbine blades 7, it drives the turbine blades 7 to rotate. The rotation of the turbine blades 7 drives the moving rod 8 to rotate. The rotation of the moving rod 8 drives the fixed plate 10 at its bottom to rotate. The rotation of the fixed plate 10 pushes the filter plate 5 upward through the sliding engagement of the second protrusion 11 and the first protrusion 9. At the same time, it causes the spring 18 to contract. When the second protrusion 11 and the first protrusion 9 are no longer in contact, the spring 18 returns to its original state and drives the filter plate 5 to move downward. This causes the filter plate 5 to sieve up and down repeatedly, thereby preventing impurities and particles in the leachate from clogging the filter holes and ensuring the filtration efficiency of the leachate.

[0039] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
