Abstract	Researchers fabricated an air-lift-type microbial carbon capture cell (ALMCC) using an air-lift-type photobioreactor as the cathode chamber. They studied performance of ALMCC in fixing high concentration of CO2, producing energy, and removing COD together with nutrients, comparing it with the traditional microbial carbon capture cell (MCC) and air-lift-type photobioreactor (ALP). The ALMCC system produced a maximum power density of 972.5 mW·m?3 and removed 86.69% of COD, 70.52% of ammonium nitrogen, and 69.24% of phosphorus, suggesting that ALMCC performed better than MCC in terms of power generation and wastewater treatment efficiency. In this work, the established ALMCC system simultaneously achieved the high level of CO2 fixation, energy recycle, and municipal wastewater treatment effectively and efficiently.
