Description

Technical Field

[0001] The invention relates to the technical field of landfill leachate treatment, and in particular to a highly efficient landfill leachate repair treatment device and method. Background Art

[0002] Leachate, also known as the "garbage juice" of a landfill, is the liquid produced by natural decomposition, compression, and rainwater infiltration during the landfill process. This liquid contains a variety of harmful substances, including but not limited to organic matter, inorganic salts, heavy metals, pathogens, and other harmful chemicals. Due to its complexity and potential environmental hazards, the treatment and management of leachate is an important issue in modern waste treatment and environmental protection. Leachate may contain heavy metals such as lead, cadmium, and mercury, which are very likely to pollute the environment, so they need to be separated and treated.
