A novel E-peroxone process with tandem flow-through (TFT) configuration was developed in this work, and its efficacy verified via the degradation of recalcitrant compounds, i.e., dyes poly(vinyl alcohol) (PVA). The gas diffusion electrode (GDE) made carbon fiber employed as cathode, while anode ruthenium–iridium acted a dimensionally stable (DSA). system achieved oxygen self-sufficiency through an innovative transfer mode, avoiding need for additional supply. electrodes TFT ensured high utilization efficiency ozone peroxone reaction occurred continuously two adjacent chambers. H2O2 yield compared between single processes under various conditions, including flow rates, current densities, pH values. Under optimal production could remove 85.5% 73.4% PVA single-pass, respectively. Electron paramagnetic resonance (EPR) tests quenching experiments revealed that hydroxyl radicals (•OH) are primary active species. Hydroxyl played major role processes. This study demonstrates holds great promise advanced technology efficient wastewater treatment.
