Abstract

Performance of nine 0.5L microbial fuel cells (MFCs) with and without powdered activated carbon (PAC) and cultivated at different sludge retention times (SRTs) with different feed concentrations were studied and compared for their effects on wastewater treatment, biogas and power productions. The best MFC could remove the chemically oxygen demand (COD) from the palm oil mill effluent (POME) up to 64.4%. This study also showed that biogas could be better produced by the MFCs which were fed with relatively higher feed concentration compared to the MFCs fed with relatively lower feed concentration. However, it was found that the power production for the MFCs fed with relatively lower feed concentration had better power density production compared to the MFCs fed with the relatively higher feed concentration. In addition, all the MFCs cultivated at longer SRTs with PAC could perform better in terms of biogas production, COD removal rate and power production.
新型粉状活性炭混合微生物燃料电池处理棕榈油厂废水的性能研究
研究了9个0.5L微生物燃料电池(mfc)在不同饲料浓度下,添加和不添加粉末活性炭(PAC)以及不同污泥滞留时间(SRTs)下的性能,并比较了它们对废水处理、沼气和发电的影响。最佳MFC对棕榈油厂废水(POME)的化学需氧量(COD)去除率可达64.4%。本研究还表明,饲喂较高饲料浓度的mfc比饲喂较低饲料浓度的mfc能更好地产沼气。然而,研究发现,相对于饲料浓度较高的mfc,饲喂较低饲料浓度的mfc具有更好的功率密度生产。此外,在较长srt下使用PAC培养的mfc在产气量、COD去除率和发电量方面均表现较好。
