Description
Summary:The disposal of leachate has become one of the most pressing problems for landfills. This study taking three kinds of amendments, corn straw, mushroom residue and garden waste as adsorbent materials, evaluates the different amendments on the leachate adsorption effect through analyzing indicators as the saturation adsorption ratio, sulfur containing odor emission, heat value. The results showed that all three kinds of amendments can effectively adsorb leachate, with saturation adsorption ratio between 1: 2 and 1: 4. Adding amendment could significantly reduce the sulfur containing odor emission of leachate. Compared the three kinds of amendments, mushroom residue could adsorb leachate at a maximize degree with a low concentration of sulfur containing odor emission. The industrial analysis showed that the heat values of the amendments after absorbing leachate are more than 14MJ/kg, and it can be utilized as a biomass fuel.
