Agro-industry wastewaters normally contain high levels of organic matter and require suitable treatment before discharge. The use of Microbial fuel cells, a novel wastewater treatment, can provide advantages over existing treatment methods. In this study, an up-flow bio-filter circuit (UBFC) for treating wastewaters without chemical treatment or nutrient supplement, was developed to solve a clogging problem. The optimal conditions included an organic loading rate of 30.0 g COD/L-d, hydraulic retention time of 1.04 day, pH level of 5.6-6.5 and aeration at 2.0 L/min. External resistance of the circuit was tested. COD removal levels of 8.08, 20.1 and 26.67 g COD/L-d were obtained, while fed with sea food, biodiesel and palm oil mill wastewater, respectively. These rates are higher than for conventional technologies. The carbon fiber brush immobilized base increased the performance of the new UBFC by 17.54% over that obtained in a previous study, while the cost was slightly decreased about 4.48%.
农业工业废水通常含有高水平的有机物，在排放之前需要进行适当的处理。微生物燃料电池作为一种新型的废水处理方法，具有比现有处理方法更具优势。在这项研究中，开发了一种上流式生物滤池电路（UBFC），用于处理无需化学处理或营养补充的废水，以解决堵塞问题。最佳条件包括有机负荷率为 30.0 g COD/L-d、水力停留时间为 1.04 天、pH 值为 5.6-6.5 和以 2.0 L/min 的速率曝气。测试了电路的外部电阻。分别用海鲜、生物柴油和棕榈油厂废水进料时，获得了 8.08、20.1 和 26.67 g COD/L-d 的 COD 去除率，高于传统技术。碳纤维刷固定基增加了新的 UBFC 的性能，比之前的研究提高了 17.54%，而成本略有降低，约为 4.48%。
