| Outline of Final Research Achievements |
The purposes of this study is aim to propose simple and economical methods to recover or supply electrons to sediment for the sediment treatment, and to examine the potential of using treated sediment as useful resources. (1) Electron recovery can dissociate metal complexes within sediment, and supplying a small amount of electrons to the sediment in the course of electron recovery can enhance the decomposition of organic matter. (2) Electron recovery from sediment can improve the reduction level of sediment, leading to the restoration of benthos inhabitation. (3) Electron-recovered sediment (treated sediment) can be used as an agriculture fertilizer. (4) Treated sediment can be used as a mediator in sediment microbial fuel cells (SMFCs), which can increase the performance of SMFCs. (5) Mixing treated sediment with sediment can facilitate the decomposition of organic matter within the mixed sediment.
