GAS PARAMETERS IN DEVELOPING LANDFILL BIOREACTOR LYSIMETER

Abstract

Municipal Solid Waste (MSW) has attained an alarming dimension for their management in developing counties during the last few decades due to rapid ur and dev In Sri Lanka, management of MSW has become a serious problem due to increase in waste generation and lack of suitable disposat facilities. Open dumping is the most common solid waste disposal method in. the region. Landfills are needed in any integrated solid waste management system and it is the core of the ies available for ing wastes. As a this study on landfill bioreactor is an attempt to upgrade prevailing dumpsites by improving the reduction in gaseous emissions. The constructed landfill bioreactor lysimeter mainly consists of main reactor, leachate collection, storage, and recirculation and gas collection systems. The parameters of gas production and composition were anal sized in the lysimeter for 116 days. This lysimeter produced maximum of 119 liters of gas/day (6.639516 m/kg of dry matter/year), which comprises cent percent H2 up to 42 days and gradually reduced towards meth is. The analyzed showed that the same trends like in previous literature even though the accelerated degradation in this lysimeter shortened the each phases due to leachate re-circulation. It was shown that the bioreactor 1 the dation process by shortening the acid phase and early initiation of methanogenesis phase.
