Description

Technical Field

[0001] This utility model relates to the field of landfill leachate treatment technology, and more specifically, to a landfill leachate biological treatment device. Background Technology

[0002] During the process of landfilling and disposal, garbage undergoes biochemical degradation processes such as compaction and fermentation, and is also exposed to precipitation and groundwater seepage, producing a liquid with a high concentration of organic or inorganic components. This liquid is called landfill leachate, also known as leachate. Landfill leachate is a high-concentration organic wastewater with highly variable water quality and quantity over time, complex composition, high BOD and COD values, high ammonia nitrogen and heavy metal content, high color, and a foul odor. Improper treatment can cause serious harm to the environment and human health.

[0003] However, most existing landfill leachate treatment methods directly filter the leachate through biological packing media. This method leads to a shortened lifespan for the biological packing media, and frequent replacement of the biological packing media is also quite troublesome. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a biological treatment device for landfill leachate, which solves the technical problem mentioned in the background art that most existing landfill leachate treatment methods directly filter the leachate through biological packing, which leads to a shortened service life of the biological packing.

[0029] In summary, when using the overall equipment: firstly, the landfill leachate can be added into the housing 1 through the feed pipe 29. Then, the internal filter plate 2 can filter the residue in the landfill leachate. After filtration, the leachate will come into contact with multiple storage boxes 15 and biological packing material 18 inside the treatment tank 13, so that the biological packing material 18 can further treat the leachate. Subsequently, the storage box 15 can be disassembled by removing the bolts on the hook 28 to facilitate the replacement of the biological packing material 18 inside.
