Abstract：
The microbial fuel cell (MFC) is considered a modern technology used for treating wastewater and recovering electrical energy. In this study, a new dual technology combining MFC and a specialized biofilter was used. The anodic materials in the system were crushed graphite, either without coating (UFB-MFC) or coated with nanomaterials (nano-UFB-MFC). This biofilter served as a barrier to retain and remove turbidity and suspended solids, while also facilitating the role of bacteria in the removal of organic pollutants, phosphates, nitrates, sulfates, oil and greases. The results demonstrated that both systems exhibited high efficiency in treating kitchen wastewater, specifically greywater and dishwashing wastewater with high detergent concentrations. The removal efficiencies of COD, oil and grease, suspended solids, turbidity, nitrates, sulfates, and phosphates in first UFB-MFC were found to be 88, 95, 89, 86, 87, 75, and 94%, respectively, and in Nano-UFB-MFC were 86, 99, 95, 91, 81, 88, and 95%, respectively, with a high efficiency in recovering bioenergy reaching a value of 1.8 and 1.5 A m-3, respectively. The results of this study demonstrate the potential for developing MFC and utilizing it as a domestic system to mitigate pollution risks before discharging wastewater into the sewer network.
摘要：
微生物燃料电池（MFC）被认为是用于处理废水和回收电能的现代技术。在这项研究中,使用了一种结合MFC和专用生物过滤器的新双重技术。系统中的阳极材料是破碎的石墨，无涂层(UFB-MFC)或涂覆纳米材料(nano-UFB-MFC)。这种生物过滤器作为屏障，以保留和去除浊度和悬浮固体，同时也促进细菌在去除有机污染物中的作用，磷酸盐,硝酸盐，硫酸盐，油和润滑脂。结果表明，两种系统均表现出处理厨房废水的高效率，特别是高洗涤剂浓度的灰水和洗碗废水。COD的去除效率,油和润滑脂，悬浮固体，浊度,硝酸盐，硫酸盐，发现第一个UFB-MFC中的磷酸盐为88、95、89、86、87、75和94％，分别,在Nano-UFB-MFC中，分别为86、99、95、91、81、88和95％，分别,回收生物能源的效率高，分别达到1.8和1.5Am-3的值。这项研究的结果表明，在将废水排放到下水道网络之前，开发MFC并将其用作家庭系统以减轻污染风险的潜力。
