【Abstract】：Toefectivelysolve theenvironmental problemsof soil，waterandatmosphere polutioncaused by leachate from garbage，break through the bottleneck of high energy consumption and easy secondary polution in traditional treatment，and explore the potential resources of high concentration organic matter that can be utilized， promoting the transformation of solid waste treatment towards resource utilization.This study takes the leachate froma large domestic waste incineration plant as an example.By continuously monitoring the annual changes in leachateindicators，the seasonal variationcharacteristicsofleachatepolutants arestudied.The removal methods of harmful substances suchas leachate pH，totalnitrogen，total phosphorus，and heavy metals that affect organic matter eficiencyare explored，and theremoval efectof alkaline flocculation on pollutants is explored.The results showed that the pH，COD，total nitrogen，and heavy metals （arsenic，chromium， lead）concentrationof leachate from garbage incineration plants vary greatly due to seasonal factors，showing significant seasonal diffrences.The alkaline flocculation method has a higher removal rate for major polutants such as total nitrogen，total phosphorus，and heavy metals，and can retain more than 95% of the organic matter in the leachate.
