Abstract：In order to address the issue of system contamination caused by the treatment of copper ions （ Cu2+ ）wastewater usingelectrochemicaltechnology，whichleads topoorsystem stability，thispaper focusedonthepolutioncharacteristicsof the system during the removal of Cu2+ byflow electrode capacitive deionization（FCDI），and explored the influence mechanism of key parameters such as applied voltage，inlet Cu2+ concentration，flow electrode velocity，and inlet water quality on the Cu2+ removal performance of the system.The results show that under the conditions of an applied voltage of 0.8V ，an influent Cu2+ concentration of 50mg/L ，and a flowing electrode flow rate of 1.2mL/min ，the Cu2+ removal rate reaches 56.22% ，the charge efficiency is 90% ，and the copper removal rate is 0. 03μmol/（cm2⋅min） .At the same time，the continuous operationstabilityoftheflow electrodesystemunderdiferentcyling modesisinvestigated，andthepolution characteristicsof theionexchange membraneandactivatedcarbonelectrodeareanalyzed.Theresultsindicatethattheflow electrodeexhibitssignificant advantages incopper ionremovalunderthesinglecycle（SC）mode，and themembraneand electrodeexhibitthelowestlevelofpollution.ThisstudyprovidesimportantreferencefortheappicationofFCDItechnologyin heavy metal removal.
