In this study, a pilot-scale Fresnel lens mounted inclined plate curvature channel (IPCC) solar photo-Fenton reactor was well designed, established, and evaluated for the treatment of the electro-optical industry wastewater. Under an initial pH of 3.0, a [H2O2]0/COD0 ratio of 2, and a [H2O2]0/[Fe2+]0 ratio of 7.5 for a reaction time of 60 min, the COD of the wastewater could reach a reduction of 85–90% which meets the effluent standard of EPA, Taiwan (COD < 100 mg/L). In addition, it was found that solar light could be concentrated, which resulted in an increase in intensity for 1.89 to 3.76 times and the temperature of the wastewater could be raised for 8 to 16°C. Therefore, the residual COD of the electro-optical industry wastewater was also kept under 100 mg/L after a 60 min of treatment even in winter season. Furthermore, the microtoxicity of the wastewater was essentially removed. Accordingly, these results illustrated that the IPCC reactor showed a synergistic effect on the solar photo-Fenton process not only in effectively dealing with a large amount of industrial organic wastewater, but also in the sector of energy conservation in terms of effective utilization of solar energy.
