APPLICATION OF THE IN-SITU AEROBIC STABILIZATION TECHNOLOGY: FIRST RESULTS AFTER 8 MONTHS OF OPERATION OF THE FIRST FRENCH FULL-SCALE PILOT

摘要

Landfill management by anaerobic bioreactor has been studied and developed over the last decade and has proven its positive impacts concerning the acceleration of biodegradation and biogas production. However, late in the life of a non-hazardous waste landfill site, managed with or without leachate recirculation, there is a period during which biodegradation is slower but still produces biogas, in smaller quantities. It seems important to find a way of managing those landfills to accelerate the final phase of the degradation of waste while reducing the polluting potential of effluents involved. The development of landfill aeration, also called aerobic bioreactor, can answer to this need for new management. Several aerations projects worldwide have been described in literature but the aeration technology has not been applied to landfills in France yet. In this context, SITA France, in collaboration with ARCADIS, is conducting a R&D project on landfill aeration. This paper presents the experimental aeration plant, the initial characterization of the waste and effluents and results of the first on-site aeration trials.
