Bioelectricity generation and remediation of sulfide contaminated tidal flat sediment

International Journal of sediment Research 2020年第1期35卷 91-96页

作者： M.Azizul Moqsud Department of Civil and Environmental Engineering University of California

A dramatic decrease in the catch of shellfish has been observed due to the high amount of Acid Volatile Sulfide(AVS) in the tidal flats in *** the current study,an evaluation of simultaneous bioelectricity generation and remediation of sulfide contaminated tidal flat sediment has been *** sediment samples collected from Tokyo Bay and Yamaguchi Bay,Japan,have been used in the laboratory test.A 2 L cylindrical shaped sediment microbial fuel cell(SMFC) has been used to evaluate the remediation of both sediment samples in the *** different electrode materials carbon felt,carbon fiber and bamboo charcoal were used in the experiments to compare their efficiency to reduce the AVS from the sediment and generate *** was observed that the AVS reduction was higher at 5 cm depths for the Tokyo Bay sediment(100%) compared to the Yamaguchi Bay sediment(60%).The larger grain size for the Tokyo Bay sediment was the probable reason for *** maximum voltage was around 100 and80 mV for Tokyo Bay and Yamaguchi Bay,respectively.
