Resumen

This study aimed to remove antibiotic residues from wastewater and assess greenhouse gas emissions, energy generation, and chlorophyll production using microbial fuel cells combined with constructed wetlands (CW-MFC). Two hydraulic retention times (HRT) of one and two days, two types of electrodes—graphite and bioelectrodes—and a control with no electrodes were employed. The results indicated complete removal of Tetracycline (TET) within three days and over 98.0 % removal of Norfloxacin (NOR) in all treatments, with no significant differences in their removal (p > 0.05). For Chloramphenicol (CHL), the two-day HRT was more effective (85.2 %) than the one-day HRT (68.1 %) (p = 1.11e-06). Significant differences were observed regarding ammonium, with better results for the two-day HRT and in the order control > graphite > bioelectrode (p = 0.00758). Chlorophyll production was higher in the wetlands with bioelectrode and two-day HRT (55.6 SPAD) than in the graphite electrode. Regarding gas emissions, CW-MFC treatments reduced CO₂ and H₂S emissions more effectively than the control group, which released lower oxygen levels. Lastly, wetlands with bioelectrodes achieved the highest potential differences: bioelectrode2 (0.22 ± 0.12 mV) and bioelectrode1 (0.16 ± 0.02 mV). These findings demonstrate the potential of CW-MFC technology, optimized with HRT and bioelectrodes, for efficient antibiotic removal, greenhouse gas mitigation, and bioenergy generation. Integrating microbial fuel cells with constructed wetlands achieved over 98.0 % antibiotic removal, enhanced ammonium reduction, and increased chlorophyll production. CW-MFC systems emerge as a sustainable and effective alternative to conventional wastewater treatment.
