A plug flow multi-electrode bioelectrochemical reactor for wastewater treatment and simultaneous generation of electricity has been developed and its efficiency investigated. It employs a horizontally located anodic zone in which the anodic electrodes comprise porous graphite plates coated with palladium. The aerated immersed cathodic electrodes contain iron(II) phthalocyanine as a catalyst. The parameters of the device were obtained using glycerol and acetate as fuels and anaerobic sludge as an inoculum. The maximal volumetric power and current densities obtained, relative to the total volume of the anodic zone, were: glycerol: 73+/-1 mA/L; 43+/-1 mW/L; acetate: 75+/-1 mA/L; 40+/-1 mW/L. It was shown that biotransformation of glycerol into volatile fatty acids does not depend on the presence of anodic electrodes in the reaction zone, while acetate degradation takes place only if the reaction zone contains anodic electrodes as a final electron acceptor.
一种用于废水处理并同时发电的推流多电极生物电化学反应器已被开发出来，并对其效率进行了研究。它采用水平放置的阳极区，其中阳极电极由涂有钯的多孔石墨板组成。曝气浸没式阴极电极含有铁（II）酞菁作为催化剂。该装置的参数是使用甘油和乙酸盐作为燃料，厌氧污泥作为接种物获得的。相对于阳极区的总体积，获得的最大体积功率和电流密度分别为：甘油：73±1 mA/L；43±1 mW/L；乙酸盐：75±1 mA/L；40±1 mW/L。结果表明，甘油向挥发性脂肪酸的生物转化不依赖于反应区中阳极电极的存在，而乙酸盐的降解仅在反应区含有作为最终电子受体的阳极电极时才会发生。
