The Acceleration of Methane Production by Leachate Recirculation in Pilot Scale in a Landfill
Leachate recirculation has the better effect to the biogas production in landfill. A pilot scale test of leachate recirculation considered the gas and liquid well was conducted in a landfill. The long term record of the leachate recirculation volume and gas production was preserved. The variation of the methane production was addressed under different recirculation schemes. The recirculation loading was the key parameter in recirculation scheme, especially considering the special condition in landfill. The recycling program and collection method implemented in the sites have an important effect on the evaluation of leachate recirculation for methane generation enhancement. It will be provided useful evidence for assessing the gas production by Leachate recirculation and collection well design in landfill.
