An upflow mode membrane-less microbial fuel cell(ML-MFC、was designed for wastewamr treatment.Granular graphite electrodes,which are fiexible in size,were adopted in the ML-MPC.Microbes present in anaero-bic activated sludge were used as the biocatalyst and artificial wastewater was tested a.s substrate.During the elec-volume was generated by the ML-MFC running in batch mode.The voltage OUtput decreased from 203 mV tO about 190 mV after the ML-MFC was changed from batch mode to normally continuous mode,indicating that planktonic electrochemically active bacterial strains in the ML.MFC may be carried away along with the effluent.Cyclic voltammograms showed that the attached microbes possessed higher bioelectrochemica]activity than the planktonic microbes.Forced aeration to the cathode benefited the electricity generation obviously.Higher Ieeding rate and longer electrode distance both increased the electricity generation.The coulombic yield was not more than 20% throughout the study,which is lower than that of MFCs with membrane.It iS proposed that dissolved oxygen dif-fused-from the cathode tO the anode may consume part of the substrate.
