Nitrogen removal and microbial metabolic analysis in an iron-carbon based constructed wetland-microbial fuel cell for mariculture wastewater treatment

Lei Wang, Tianyu Zhao, Zerui Gong, Xiaobo Ban et autres

Mariculture wastewater is characterized by high salinity and rich nitrogen compounds, which pose significant threats to marine ecosystems. While conventional constructed wetlands (CWs) have demonstrated effective performance in treating freshwater aquaculture wastewater, their efficiency often decreases under high salinity conditions. Currently, studies …
