摘要：The idea is immensely attractive if copper ions can be completely removed in wastewater. In this study, a novel bioelectrochemical system assisted microelectrolysis was developed for the enhanced removal of copper. One abandoned aluminium was used as anode and graphite/activated carbon as biological anode, and a bifunctional catalytic conducive membrane as cathode. Under the combined action of electroreduction and electroflocculation, copper ions directly pumped into the cathode chamber were efficiently treated, and organic matter was synchronously removed (Copper ions > 99.9%, TOC > 98.2%, COD > 97.9%, NH4+-N > 94.5% and TP > 94.9%). The reactions of primary batteries and microelectrolysis in anode chamber significantly enhanced the self-production capacity of BES (maximum power density of 2250 mW m(-3) M current density 10.65 mA m(-2), maximum cell voltage of 1.4 V). The results confirmed the application potential of bioelectrochemical system assisted microelectrolysis for the removal of copper.
