The performance of sediment microbial fuel cells (SMFCs) was evaluated in the presence of cellulose in the aquaculture pond sediment as 2% (w/w) in SMFC-2, 4% in SMFC-3 and without adding cellulose in SMFC-1. From aquaculture water, average chemical oxygen demand (COD) and total nitrogen (TN) removal efficiencies of 80.6±0.3% and 83.0±0.01% were obtained in SMFC-1, 88.2±0.5% and 89.6±0.8% in SMFC-2 and 83.1±0.3% and 64.5±1.6% in SMFC-3, respectively. During the complete experimental period, acetic acid was the only short chain fatty acid detected in all three SMFCs. Sediment organic matter removal in SMFC-1, SMFC-2 and SMFC-3 were 16%, 22% and 18.6%, respectively. SMFCs demonstrated effective cellulose degradation from aquaculture pond sediment and maintained the oxidized sediment top layer favourable for aquaculture.
在水产养殖池塘底泥中添加 2%（w/w）纤维素作为 2%（w/w）（SMFC-2）、4%（w/w）纤维素作为 4%（w/w）（SMFC-3）和不添加纤维素作为对照（SMFC-1）的条件下，评估了沉积物微生物燃料电池（SMFCs）的性能。从养殖水中，SMFC-1 中获得了平均化学需氧量（COD）和总氮（TN）去除效率为 80.6±0.3%和 83.0±0.01%，SMFC-2 为 88.2±0.5%和 89.6±0.8%，SMFC-3 为 83.1±0.3%和 64.5±1.6%。在整个实验期间，在所有三个 SMFC 中都只检测到了乙酸这一种短链脂肪酸。SMFC-1、SMFC-2 和 SMFC-3 中的沉积物有机质去除率分别为 16%、22%和 18.6%。SMFCs 有效地从水产养殖池塘底泥中降解了纤维素，并保持了氧化的底泥上层有利于水产养殖。
