The disposal of landfill leachate has been a very difficult problem in landfill design, operation and management. Leachate is the product of the gravity flow of liquids in landfills and is primarily derived from precipitation and the inherent moisture content of the refuse itself. The properties of the percolate vary over a considerable range, since many factors in the flow of the liquid may influence the properties of the percolate, including physical, chemical and biological factors. The concentration of the heavy metal is basically consistent with that of the heavy metal in the municipal sewage. The leachate of the municipal refuse landfill is high-concentration organic wastewater with complex components, and if the leachate is directly discharged into the environment without treatment, serious environmental pollution is caused. For the purpose of protecting the environment, it is essential to treat the leachate.
