Leachate treatment system for waste landfill

摘要

The present invention relates to a leachate treatment system for waste landfills, and more specifically to a leachate treatment system for waste landfills, wherein the system sequentially performs a series of steps comprising: a water storage step for leachate; a chemical aggregation processing step for aggregating a pollutants mixed into the pollutant via a chemical aggregation processor and for collecting the aggregated pollutants by making the aggregated pollutants float; a biological decomposition processing step for removing by biologically decomposing, via microorganisms, the leachate undergone the chemical aggregation processing step; a sludge processing step for separating sludge from purified water undergone the biological decomposition processing step; and a dehydration step for dehydrating the sludge separated and removed by the biological decomposition processing step and the sludge processing step for separating. By stably decomposing and removing pollutants, the present invention can stably treat leachate.
