[0002] Landfill leachate is a high-concentration organic wastewater produced during the landfilling and disposal of waste through biological decomposition and rainwater leaching. Its composition is complex, containing not only large amounts of organic matter and ammonia nitrogen, but also rich in various heavy metal ions and high concentrations of salt, making it extremely difficult to treat. Direct discharge of untreated landfill leachate will severely pollute soil, surface water, and groundwater, harming the ecological environment and human health. Therefore, developing efficient, economical, and environmentally friendly treatment processes for high-salinity landfill leachate wastewater is urgently needed.
[0003] Existing high-salinity wastewater treatment processes include multiple steps such as pretreatment, coagulation sedimentation, and ammonia stripping. In the coagulation sedimentation process, the current method is to directly add coagulants and coagulant aids to the surface of the water body for stirring and mixing, which reduces the efficiency of stirring and mixing.
