Simulation Tests of Biodegradation and Compression of Municipal Solid Waste
Abstract In this paper, biodegradation-compression tests were carried out to investigate the dependence of longterm settlement behavior of municipal solid waste (MSW) on stress level. Three biodegradation-compression test apparatuses were purposely developed. The apparatuses were equipped with units for vertical loading, leachate recirculating, gas collecting, and temperature controlling. Fresh MSW samples were compacted the prescribed density in the test apparatus, and then subjected to three different stress levels (100,200 and 400 kPa). Biodegradation processes of the MSW samples were simulated at the controlled temperature (41 °C) and under a leachate recirculation condition. The compression and gas production of the samples were recorded. The experimental results indicated that the secondary compressibility parameters of the MSW are dependent on the vertical stress level. It seems that the gas production rate of the MSW is independent of the stress level.
