In order to provide an alternative for removal of algal organic matter (AOM) produced during algal blooms in aquatic environment, microbial fuel cell (MFC) was used to study AOM degradation and its association with THM precursor removal. The chemical oxygen demand (COD) removals in MFCs were 81 ± 6% and 73 ± 3% for AOM from Microcystis aeruginosa (AOM(M)) and Chlorella vulgaris (AOM(C)), respectively. THM precursor was also effectively degraded (AOM(M) 85 ± 2%, AOM(C) 72 ± 4%). The major AOM components (proteins, lipids, and carbohydrates) were obviously removed in MFCs. The contribution of each component to the THM formation potential (THMFP) was obtained based on calculation. The THMFP produced from soluble microbial products was very low. If the energy input during operation process was not considered, MFCs treatment could recover electrical energy of 0.29 ± 0.02 kWh/kg COD (AOM(M)) and 0.35 ± 0.06 kWh/kg COD (AOM(C)).
为了提供一种替代方法来去除水生环境中藻类大量繁殖产生的藻源有机物（AOM），本研究采用微生物燃料电池（MFC）来研究 AOM 的降解及其与三卤甲烷（THM）前体去除的关系。MFC 对铜绿微囊藻（AOM(M)）和普通小球藻（AOM(C)）来源的 AOM 的化学需氧量（COD）去除率分别为 81±6%和 73±3%。THM 前体也得到了有效去除（AOM(M) 85±2%，AOM(C) 72±4%）。MFC 中明显去除了主要的 AOM 成分（蛋白质、脂质和碳水化合物）。根据计算得到了各成分对三卤甲烷生成潜能（THMFP）的贡献。可溶微生物产物产生的 THMFP 非常低。如果不考虑运行过程中的能量输入，MFC 处理可以回收 0.29±0.02 kWh/kg COD（AOM(M)）和 0.35±0.06 kWh/kg COD（AOM(C））的电能。
