Power Generation Enhancement by Utilizing Plant Photosynthate in Microbial Fuel Cell Coupled Constructed Wetland System

Constructed Wetland Treatment Plant Constructed Wetland Microbial Fuel Cells

18 This work aimed at determining the amount of energy that can be harvested by 19 implementing microbial fuel cells (MFC) in horizontal subsurface constructed wetlands 20 (HSSF CWs) during the treatment of real domestic wastewater. To this aim, MFC were 21 implemented in a pilot plant based on two HSSF CW, one fed with primary settled 22 wastewater (Settler line) and the other fed with the eff...

Optimization of Bioelectricity Generation in Constructed Wetland-Coupled Microbial Fuel Cell Systems

Constructed wetland-coupled microbial fuel cell systems (CW-MFCs) incorporate an aerobic zone and an anaerobic zone to generate electricity that achieves the oxidative degradation of contaminants. However, there are few reports on the performance of such coupled systems. In this study, we determined the optimal configuration of CW-MFCs to characterize their electricity generation performance. B...

A review of microbial fuel cells coupled with constructed wetland

Feasibility study of simultaneous azo dye decolorization and bioelectricity generation by microbial fuel cell-coupled constructed wetland: substrate effects

Microbial fuel cells (MFCs) were embedded into constructed wetlands to form microbial fuel cell coupled constructed wetlands (CW-MFCs) and were used for simultaneous azo dye wastewater treatment and bioelectricity generation. For the first time, the effects of different substrate biomass on the performance of CW-MFCs were studied. Group A had the highest substrate biomass of 0.453 g VSS per L, ...

Treatment of Oil Wastewater and Electricity Generation by Integrating Constructed Wetland with Microbial Fuel Cell

Conventional oil sewage treatment methods can achieve satisfactory removal efficiency, but energy consumption problems during the process of oil sewage treatment are worth attention. The integration of a constructed wetland reactor and a microbial fuel cell reactor (CW-MFC) to treat oil-contaminated wastewater, compared with a microbial fuel cell reactor (MFC) alone and a constructed wetland re...
