[0002] Landfills are common waste disposal facilities used to dispose of municipal solid waste. At landfills, waste is dumped into pits and then covered with a layer of material (such as soil or plastic film) to reduce the entry of oxygen and water, thereby slowing down the decomposition process and the release of harmful gases. Landfill leachate is the liquid that forms when moisture from the waste and rainwater seeps into the landfill during the landfilling process. This liquid contains organic matter, heavy metals, nitrogen, phosphorus, and other substances, and if not properly treated, it can pollute the surrounding environment. Treating landfill leachate is a crucial aspect of environmental protection.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Please see Figure 1-5 The present invention provides a technical solution:

[0026] A landfill leachate grading treatment device includes a purification tank 1, a plurality of purification balls 2 are equidistantly arranged on the top of the purification tank 1, and a storage pan 3 is connected to the top of the plurality of purification balls 2.

A permeable mesh plate 10 is set at the bottom of the landfill leachate frame 9.

[0027] The bottom of the leachate collection box 9 is equipped with a buckle plate, and a motor 11 is installed on the buckle plate. The output end of the motor 11 is connected to a linkage plate 12, and a scraper 13 is connected to the side wall of the linkage plate 12. The motor 11 can be started to drive the scraper 13 to promote the movement of the garbage and facilitate the discharge of leachate.

[0028] The side wall of the purification tank 2 5 is symmetrically provided with column plates 14. The top of the column plates 14 is connected to the uprights 15.
