The electro-assisted Fenton-like (EAF-like) and photoelectro-assisted Fenton-like (PEAF-like) processes were applied to real dye factory wastewater to evaluate pollutant degradation and toxicity reduction. A Box-Behnken design optimized the process for maximum total organic carbon (TOC) removal and color degradation while minimizing specific energy consumption (SEC). ANOVA results confirmed model reliability, with R2 values of 99.18 % (TOC), 99.31 % (color), and 99.99 % (SEC) for EAF-like, and 99.80 % (TOC), 99.82 % (color), and 99.98 % (SEC) for PEAF-like. The optimal EAF-like conditions (4.7 g/L H2O2, 7 min, 9.2 V) achieved 32 % TOC removal, 90 % color removal, and an SEC of 2.86 kWh/kg TOC, whereas the optimized PEAF-like conditions (4.7 g/L H2O2, 6 min, 6.4 V, 545 mJ/cm2 light intensity) resulted in 97 % TOC removal, 91 % color removal, and a significantly lower SEC of 0.599 kWh/kg TOC. Acute toxicity assessment using Daphnia magna showed that untreated wastewater had a 94 % immobilization rate, indicating severe toxicity. EAF-like treatment reduced toxicity to 88–28 %, while PEAF-like further decreased immobilization to 23–4 % under optimal conditions. The superior pollutant removal, energy efficiency, and toxicity reduction of PEAF-like highlight its potential as a sustainable solution for industrial wastewater treatment, demonstrating the significance of process optimization for large-scale applications. These findings suggest that the PEAF-like process is a highly efficient and energy-saving alternative for treating complex industrial wastewater, contributing to environmental sustainability and reducing ecological risks.
