Geoenvironmental Condition Improvement by Using Microbial Fuel Cell
Publication: Geo-Congress 2023
ABSTRACT
Soil pollution is one of the main causes of the declination of shells and other sea creatures that live in the tidal flat area in Japan. The geotechnical approach to clean the polluted soil by mixing it with sand and recycled waste glass is difficult as it can cause some problems to the natural habitat of the living creatures. In this study, the microbial fuel cell, which is a bioelectrochemical device, has been used to remediate the pollution. It has been observed that the acid volatile sulfide (AVS) of polluted soil has been significantly decreased by using the microbial fuel cell. The application of the microbial fuel cell has been increasing the flow of electrons inside the anode area and thus enhancing the activity of the sulfate-reducing bacteria and other geobacteria. The voltage generation has been monitored during the process and has been noticed a significant increase of the voltage with duration. Thus, microbial fuel cells can be used to solve the problem of soil pollution and make suitable inhabitants for living creatures, and at the same time, it can generate some bioelectricity to power the environmental monitoring sensors.
