Electroplating wastewater contains high concentrations of dissolved organic matter, heavy metal ions (HMs), refractory organic compounds (ROC), and the complicated composition of effluents. Bioaugmentation presents an efficient strategy for eliminating pollution and recycling resources from electroplating effluent. In this study, simultaneous removal of pollution and sustainable resources recovery from electroplating wastewater were conducted by polyferric sulfate (PFS)-based coagulation, ultraviolet (UV)-activated persulfate (PS) (UV-APS)-based advanced oxidation coupling with bioaugmentation. To reduce carbon emissions and achieve carbon neutrality, genetically engineered Vibrio natriegens with an aerobic sulfate reduction pathway (GeVin) was introduced to remove sulfate, organics, and HMs, which further promoted generation of metal sulfides. The results of coagulation by PFS eliminated 34.68% of chemical oxygen demand (COD), 38.56% of ammonia nitrogen (NH
