[0002] Landfill leachate refers to the water produced during the process of landfilling or dumping waste through a series of aerobic reactions, as well as the infiltration water after rainwater leaching. Landfill leachate is a type of high-concentration organic wastewater that is produced after evaporation from the surface of the landfill, in addition to the water contained in the waste itself and the water-holding capacity of the soil.
