Recently, interest is growing to explore low-cost and sustainable means of energy production. In this study, we have exploited the potential of sustainable energy production from wastes. Activated sludge and algae biomass are used as substrates in microbial fuel cell (MFC) to produce electricity. Activated sludge is used at anode as inoculum and nutrient source. Various concentrations (1-5 g/L) of dry algae biomass are tested. Among tested concentrations, 5 g/L (5000 mg COD/L) produced the highest voltage of 0.89 V and power density of 1.78 W/m(2) under 1000 Ω electric resistance. Pre-treated algae biomass and activated sludge are also used at anode. They give low power output than without pre-treatment. Spent algae biomass is tested to replace whole (before oil extraction) algae biomass as a substrate, but it gives low power output. This work has proved the concept of using algae biomass in MFC for high energy output.
最近，人们越来越关注探索低成本和可持续的能源生产方式。在这项研究中，我们利用了从废物中生产可持续能源的潜力。活性污泥和藻类生物质被用作微生物燃料电池 (MFC) 的底物来发电。活性污泥用作阳极的接种物和营养源。测试了各种浓度（1-5 g/L）的干藻类生物质。在测试的浓度中，在 1000 Ω电阻下，5 g/L（5000 mg COD/L）产生的电压最高为 0.89 V，功率密度为 1.78 W/m²。预处理的藻类生物质和活性污泥也被用在阳极上。它们的输出功率比未经预处理时低。用过的藻类生物质被测试用来替代整个（在提取油之前）藻类生物质作为底物，但它的输出功率较低。这项工作证明了在 MFC 中使用藻类生物质来获得高能量输出的概念。
