有机废物的回收利用是发展中国家和发达国家的一个重要课题。有机废物的堆肥已被用作土壤改良剂。本研究利用水稻微生物燃料电池（PMFCs）在混合堆肥的土壤中产生绿色能源（生物电）。总共六个装满相同土壤的桶，使用碳纤维作为测试的电极。将水稻植物种植在五个桶中，第六个桶仅含有土壤，所有情况下均使用100欧姆的外部电阻。观察到，随着时间的推移，具有水稻植株和堆肥的电池显示出较高的电压和功率密度值。当水稻植株与1%的堆肥混合土壤时，电压的最高值显示在700 mV左右，而在没有水稻植株和没有堆肥的情况下，电压的最高值降低了95%以上。比较有堆肥和没有堆肥但具有相同数量的水稻植株的情况，有堆肥的情况下描绘了高达2倍的更高电压。将堆肥用于稻田PMFC时，功率密度也提高了3倍，这表明堆肥对生物发电的影响。(C)2014爱思唯尔有限公司版权所有。
Recycling of organic waste is an important topic in developing countries as well as developed countries. Compost from organic waste has been used for soil conditioner. In this study, an experiment has been carried out to produce green energy (bioelectricity) by using paddy plant microbial fuel cells (PMFCs) in soil mixed with compost. A total of six buckets filled with the same soil were used with carbon fiber as the electrodes for the test. Rice plants were planted in five of the buckets, with the sixth bucket containing only soil and an external resistance of 100 ohm was used for all cases. It was observed that the cells with rice plants and compost showed higher values of voltage and power density with time. The highest value of voltage showed around 700 mV when a rice plant with 1% compost mixed soil was used, however it was more than 95% less in the case of no rice plant and without compost. Comparing cases with and without compost but with the same number of rice plants, cases with compost depicted higher voltage to as much as 2 times. The power density was also 3 times higher when the compost was used in the paddy PMFCs which indicated the influence of compost on bio-electricity generation. (C) 2014 Elsevier Ltd.
