Developing an efficient dual-electrode system for peroxymonosulfate (PMS) activation is essential to expand the scope wastewater treatment and solve issues of low capacity, poor mineralization, high energy consumption. This study proposed oxygen vacancy-mediated LaCoO3-modified Ti4O7 (LCVTO) anode membrane in situ grown nanocarbon-modified carbon felt (C/CF) cathode coactivate PMS, achieving 100% sulfamethoxazole (SMX) elimination 37.3 s. The rate constant (k = 15.84 min-1) was 12 21 times higher than those processes, with consumption reduced just 7.9% 4.6%, respectively. filter supports either high-flux pollutant removal (1061 L/m2·h) or deep mineralization (89%) at 212.22 L/m2·h. In electrochemical infrared spectroscopy density functional theory calculations revealed reaction mechanism multiple active sites, (Co Vo) supplying •OH, SO4•-, 1O2 nanocarbon on contributing additional 1O2. process demonstrated excellent pH adaptability (4-14) SMX removal, outstanding reusability, continuous operation capability. Its resilience matrix interference enables economical both high-conductivity mariculture low-conductivity municipal sewage remarkably electric (0.08-0.16 kWh/kg COD). approach offers promising prospects addressing water pollution challenges across industrial environmental contexts.
