This study demonstrated the effectiveness of single chamber up-flow membrane-less microbial fuel cell (UFML-MFC) in wastewater treatment concurrently with bioelectricity generation. The objectives of this study were to examine the effect of influent substrate concentration (0.405 g/L, 0.810 g/L, 1.215 g/L, 1.620 g/L), anode distributions (11 cm, 17 cm, 23 cm ) and surface morphologies for biofilm formation on the performance of wastewater treatment and power generation. The optimum performance was obtained with substrate concentration of 0.810 g/L. The COD removal efficiency, output voltage, internal resistance, power density and current density obtained were 84.64%, 610 mV, 200 Ω, 162.59 mW/m² and 468.74 mA/m², respectively. The Coulombic Efficiency (CE), Normalized Energy Recovery (NER_S and NER_v) were 1.03%, 789.38 kWh/kg COD and 22.56 kWh/m³, respectively. The results also indicate that the output voltage and power generation obtained in a continuous up-flow MFC were higher with A3 (23 cm), which is of larger electrodes spacing followed by A2 (17 cm) and A1 (11 cm) caused by the enrichment of anaerobic microbial population at A1.

这项研究证明了单室上流无膜微生物燃料电池（UFML-MFC）在废水处理和生物发电的同时的有效性。这项研究的目的是检验进水底物浓度（0.405 g / L，0.810 g / L，1.215 g / L，1.620 g / L），阳极分布（11 cm，17 cm，23 cm）和表面的影响生物膜形成的形态对废水处理和发电性能的影响。底物浓度为0.810 g / L时可获得最佳性能。获得的COD去除效率，输出电压，内部电阻，功率密度和电流密度分别为84.64％，610 mV，200Ω，162.59 mW / m ²和468.74 mA / m ²， 分别。库仑效率（CE），归一化能量回收率（NER _S和NER _v）分别为1.03％，789.38 kWh / kg COD和22.56 kWh / m ³。结果还表明，在连续的上流式MFC中，A3（23 cm）的输出电压和发电量更高，这是因为电极间距较大，其次是A2（17 cm）和A1（11 cm），这是由A3引起的。 A1厌氧微生物种群的富集。
