Suspension and biofilm microbial community in bioelectrochemical systems of different electrode spacing

Bioelectrochemical systems (BESs) are widely used for the removal of contaminants from wastewater because of the electrodes can be as non-exhaustible electron acceptors or donors. Reducing the electrode spacing (ES) can effectively improve the electrochemical performance. However, how the electrical properties are improved when the ES reduces remains unclear.

生物电化学系统（Bioelectrochemical systems, BESs）因电极可作为非耗竭性电子受体或供体，被广泛应用于废水污染物去除领域。减小电极间距（Electrode Spacing, ES）可有效提升其电化学性能，但目前电极间距缩小后电学性能提升的具体机制仍不明确。
