FULL-SCALE PRACTICE OF ECOLOGICALLY BASED LANDFILL OF MUNICIPAL SOLID WASTE: TO ACCECELERATE THE BIOLOGICAL CONVERSION INSIDE LANDFILL AND COVER LAYERS
The application of bioreactor landfill with leachate recirculation was usually confronted with the problems of waste acidification and high ammonia content in leachate. A modified operation called ecologically based landfill was induced by recycling the pre-treated fresh leachate into landfill and sub-irrigating the stabilized leachate into the plant-soil system of cover layers. The former accelerated the methanization of biomass waste, whereas the latter converted the ammonia nitrogen into biomass nutrients. Secondary pollution from this system was expected to be minimized. The concept of ecologically based landfill was assessed and optimized in lab- and pilot-scale, and then validated in a full-scale landfill by 3 years of practice and monitor.
