生物电化学系统（BES）可以通过在阳极氧化各种底物并同时在阴极回收金属来回收电能。将 BES 从实验室扩大到中试规模是该工艺开发过程中具有挑战性的一步，并且只有少数成功经验可供借鉴。本文提出了用于铜回收的 BES 原型。这里介绍的电池设计具有可拆卸电极，类似于电镀槽中的电极。该设计中的阳极和阴极可以独立更换。原型生物电化学电池由一个 835 cm2 的生物阳极和一个 700 cm2 的阴极组成，其中阳极供给醋酸盐，阴极供给铜。电流密度为 1.2 A/−2，发电功率为 48mW m−2。通过分析内阻分布来评估每个组件（阳极、电解质、阴极和膜）的贡献。这表明主要损失发生在阳极，并且与其他系统相比，可拆卸电极的设计会导致更高的内阻。为了进一步评估 BES 在铜回收中的实际适用性，进行了经济评估。分析表明，几个实验室规模的 BES 的内阻已经足够低，足以使系统具有经济性，而放大系统的内阻仍需要大幅改善才能实现经济适用。© 2017 作者。 《化学技术与生物技术杂志》由 John Wiley & Sons Ltd 代表化学工业协会出版。
Bioelectrochemical systems (BESs) enable recovery of electrical energy through oxidation of a wide range of substrates at an anode and simultaneous recovery of metals at a cathode. Scale‐up of BESs from the laboratory to pilot scale is a challenging step in the development of the process, and there are only a few successful experiences to build on. This paper presents a prototype BES for the recovery of copper. The cell design presented here had removable electrodes, similar to those in electroplating baths. The anode and cathode in this design could be replaced independently. The prototype bioelectrochemical cell consisted of an 835 cm2 bioanode fed with acetate, and a 700 cm2 cathode fed with copper. A current density of 1.2 A/−2 was achieved with 48 mW m−2 of power production. The contribution of each component (anode, electrolytes, cathode and membrane) was evaluated through the analysis of the internal resistance distribution. This revealed that major losses occurred at the anode, and that the design with removable electrodes results in higher internal resistance compared with other systems. To further assess the practical applicability of BES for copper recovery, an economic evaluation was performed. Analysis shows that the internal resistance of several lab‐scale BESs is already sufficiently low to make the system economic, while the internal resistance for scaled‐up systems still needs to be improved considerably to become economically applicable.© 2017 The Authors.
