Gas production by accelerated in situ bioleaching of landfills

摘要: A process for improved gas production and accelerated stabilization of landfills by in situ bioleaching organic wastes acid forming bacteria substantially sealed landfills, passing the leachate hydrolysis liquefaction products microbial action microorganisms with material to an phase digester regenerate activated culture recirculation landfill, supernatant from a methane operated under conditions produce rich gas. The containing nutrients added sewage sludge or other desired nutrient materials are circulated through landfill. Low Btu is withdrawn while high may be upgraded use as SNG. this invention applicable small well large waste provides simultaneous disposal municipal solid aqueous landfill which stabilized much more quickly than uncontrolled presently utilized.
