本研究的目的是确定植物的污染物去除和生物发电的城市污水处理与人工湿地基质厌氧微生物燃料电池（CW-MFC）相比，传统的CWs的作用。采用流加方式建立了未种植和种植的多阳极CW-MFC（黄菖蒲、风信子和芦苇）。有植被的CW-MFC模块对COD、NO3−-N、NH 4 +-N和PO 43 −-P的去除率分别为46.9- 51.6%、94.8- 97.4%、43.2- 71.5%和96.0- 97.6%，而未种植湿地模块的去除率分别为36.6%、89.9%、43.0%和97.1%。更有效的污染物去除和更高的发电量与更高的植物生长相关。在最高株高（1635 cm）处种植黄菖蒲的多阳极CW-MFC的最大功率密度为25.14 mW/m2。与未种植的CW-MFC相比，种植黄菖蒲的CW-MFC对NH 4 +-N的去除率提高了66.2%，对生物发电的贡献率提高了97.5%。结果突出了在CW-MFC基质中生长植物在加强生物能源输出方面的重要作用，与CW-MFC中的废水处理增强相比。未来的研究应集中在提高阴极电位的长期运行，并尽量减少枯萎植物的种植CW-MFC的负面作用。
The aim of this study was to determine the role of plants on pollutant removal and bioelectricity production in the treatment of municipal wastewater withconstructedwetland matrix incorporatingmicrobialfuelcells (CW-MFCs) compared to traditional CWs. Multi-anode unplanted and planted CW-MFCs (Iris pseudacorus,Hyacinth pink, andPhragmites australis) were established in fed-batch mode. CW-MFC modules with established vegetation had high treatment efficiencies with COD, NO3−-N, NH4+-N, and PO43−-P removal of 46.9–51.6%, 94.8–97.4%, 43.2–71.5%, and 96.0–97.6%, respectively, compared to 36.6%, 89.9%, 43.0%, 97.1% in the unplanted wetland module, respectively. More efficient pollutant removal and higher power production were correlated with higher plant growth. The highest maximum power density achieved was 25.14 mW/m2in the multi-anode CW-MFC planted withIris pseudacorusat highest plant height (1635 cm). The CW-MFC planted withIris pseudacorusenhanced NH4+-N removal by 66.2% and significantly contributed to bioelectricity generation by 97.5% compared to the unplanted CW-MFC. The results highlight the significant role of growing plants in the CW-MFC matrix in strengthening the bioenergy output compared with enhancement in wastewater treatment in CW-MFCs. Future studies should focus on improvement in cathode potential over a long-term operation and minimize the negative role of withered plants on the planted CW-MFCs.
