Description

Technical Field

[0001] The utility model relates to the technical field of garbage leachate treatment, in particular to a solid-liquid separation device for garbage leachate treatment. Background Art

[0002] Garbage leachate refers to a high-concentration organic wastewater formed by the water contained in the garbage itself in the landfill, the rain and snow water entering the landfill, and other water, minus the saturated water holding capacity of the garbage and the covering soil layer, and passing through the garbage layer and the covering soil layer. There is also water seeping from the accumulated garbage prepared for incineration. Garbage leachate is a very big problem in environmental governance, because garbage leachate has a very strong odor, and there are many built-in bacteria and substances that cannot be degraded independently, so it is necessary to separate and treat the garbage leachate. For this reason, we provide a solid-liquid separation device for garbage leachate treatment.

[0003] In the prior art, a Chinese patent document with publication number CN216336903U and publication date April 19, 2022 was proposed to solve the above-mentioned technical problems.

[0004] In order to solve the problem of solid-liquid separation of the leachate, the existing technology uses a layering plate to block the solid part in the liquid at the top of the layering plate, so that the leachate can be fully processed in a solid-liquid separation manner during the continuous squeezing movement of the pressure plate. However, this method causes the solids to be retained inside the separation box above the layering plate, making it inconvenient to clean. Utility Model Content
