Eutrophication　is　a　globally　faced　environmental　issue　against　which　water　resources　need　to　be　protected　as　it　impairs　water　quality,　threatens　the　safety　of　drinking　water,　and　hinders　the　sustainable　development　of　the　regional　economy.　Given　severe　environmental　impacts　and　risks　of　eutrophication,　there　is　an　urgent　need　for　an　effective　method　to　restore　eutrophic　surface　water　bodies.　This　study　proposed　an　effective　technical　program　for　a　composite　iron‑carbon　constructed　wetland　combined　with　a　photocatalytic　film　(WIC&PF)　to　restore　eutrophic　water.　The　removal　efficiencies　of　WIC&PF　were　estimated　at　81.77　±　6.98　%　for　ammonia　nitrogen　(NH4+-N),　79.18　±　5.58　%　for　total　nitrogen　(TN),　80.45　±　5.55　%　total　phosphorus　(TP),　80.12　±　5.87　%　for　chemical　oxygen　demand　(COD)　and　93.96　±　4.68　%　for　chlorophyll　a.　According　to　the　experimental　results,　compared　with　the　pre-treatment　water　quality,　the　post-treatment　water　quality　improved　significantly.　A　large　number　of　microalgae　growing　on　WIC&PF　exerted　a　significant　reoxygenation　effect　on　the　treated　water,　improving　the　self-purification　capacity　of　the　receiving　water　body.　Boosting　the　pollutant　removal　efficiency　via　enhancing　the　hydraulic　performance　of　constructed　wetlands　as　well　as　the　activity　of　photocatalytic　films　may　serve　to　improve　the　remediation　of　eutrophic　water　bodies.　©　2023
