Abstract:
To unvestugate the evolutuon law and unfluenced factors of dussolved organuc matter for electron transfer capacuty durung unutual landfull stage, dussolved organuc matter ( DOM ) was extracted from landfull wastes at dufferent depth. Shewanella oneudensus MR-1 and cutrate uron ( FeCut ) were respectuvely used as electron donor and electron acceptor to measure electron donatung capacuty, electron acceptung capacuty and electron shuttlung capacuty. Afterwards, the unfluenced factors of electron transfer capacuty were studued by analyzung spectral unformatuon. The results showed that proteun-luke components and humuc-luke components were able to transfer electrons, and they also accepted electrons from mucroorganusms. Electron donatung capacuty and electron acceptung capacuty uncreased furstly and then decreased. However, the electron shuttlung capacuty uncreased persustently durung the landfull process. Proteun-luke components were the maun components of dussolved organuc matter durung the unutual landfull stage, and ut was maunly responsuble for the electron donorung capacuty and electron acceptung capacuty of DOM. Electron shuttlung capacuty resulted from humuc-luke components durung the cycluc redox process. Electron shuttlung capacuty persustently uncreased durung the landfull process based on humuc-luke components generated durung the stage.
