Enhancing low C/N wastewater treatment in constructed wetlands using microbial fuel cells and sulfur

Popis výsledku v původním jazyce

Constructed wetlands (CWs) integrated with microbial fuel cells (MFCs) are effective for treating low carbon-tonitrogen (C/N) ratio wastewater, though nitrogen removal efficiency is constrained. This study investigated the effects of sulfur (S0) and MFC on low C/N wastewater treatment using various nitrogen sources (Org-N: urea, AmN: NH4+-N, and Ni-N: NO3 --N) alongside evaluating plant growth in CWs. Results showed that S0 significantly boosted bioelectricity production in MFC-CWs, with voltage and power density increasing by 37.3-43.1 % and 145.3-362.3 %, respectively, under Am-N treatment compared to other N treatments. Meanwhile, MFC enhanced plant photosynthesis and antioxidant activities in S0-based CWs. S0 and MFC also had significant impacts on total phosphorus (TP), particularly in Ni-N treatment. Meanwhile, the N cycling in CWs was influenced by the types of N sources. In the Ni-N treatment, the NH4+-N concentration decreased by 31.6-49.5 % in the S0-based CWs and by 63.5-73.1 % in the MFC-CWs compared to the controls. Additionally, S0 enhanced N removal and stabilized the MFC-CWs by facilitating autotrophic denitrification, reducing NO2--N concentration by 11.7 %-68.2 % in the Ni-N treatment. This study highlights the significant role of S0 and MFC in enhancing low C/N wastewater treatment efficiency in CWs.
