Improvement of Waste Decomposition in Leachate Recirculation Simulated Landfill by High Water Addition
نویسندگان
چکیده
A considerable amount of research has been conducted to demonstrate the development of bioreactor landfills promoted by leachate recirculation [1-10]. The effectiveness of leachate recirculation has been well documented in lysimeter studies [1, 5, 11, 12], test cell studies [2, 13, 14-16] and full-scale studies [17-20]. However, the results from these investigations might not be applied appropriately to Thailand N. Sanphoti , S. Towprayoon , P. Chaiprasert and A. Nopharatana 146 Asian J. Energy Environ., Vol. 4, Issues 3-4, (2003), pp. 145-161 due to the difference of waste type and composition. There are still small basic information regarding to the bioreactor improvement by high water addition and a few researches have been done in Thailand. Therefore, this investigation focuses on the improvement of leachate recirculation simulated landfill by high water addition, which help to improve the landfill not only on waste decomposition that aims to overcome the inert state of a landfill in a short time but also on leachate treatment and energy conversion as well.

Temporal and Spatial Pore Water Pressure Distribution Surrounding a Vertical Landfill Leachate Recirculation Well
Addition of liquids into landfilled waste can result in an increase in pore water pressure, and this in turn may increase concerns with respect to geotechnical stability of the landfilled waste mass. While the impact of vertical well leachate recirculation on landfill pore water pressures has been mathematically modeled, measurements of these systems in operating landfills have not been reporte...

Leachates produced at the La Zoreda landfill in Asturias, Spain, were recirculated through a simulated landfill pilot plant. Prior to recirculation, three loads of different amounts of Municipal Solid Waste (MSW) were added to the plant, forming in this way consecutive layers. When anaerobic digestion was almost completed, the leachates from the landfill were recirculated. After recirculation, ...

متن کاملEvaluation of leachate recirculation on nitrous oxide production in the Likang Landfill, China.
Landfill leachate recirculation is efficient in reducing the leachate quantity handled by a leachate treatment plant. However, after land application of leachate, nitrification and denitrification of the ammoniacal N becomes possible and the greenhouse gas nitrous oxide (N2O) is produced. Lack of information on the effects of leachate recirculation on N2O production led to a field study being c...
