Abstract
With the development of industry, the treatment of refractory organic wastewater has become a major challenge in the field of environmental protection. Traditional biological treatment methods are difficult to effectively remove some complex organic pollutants, and electrochemical oxidation method as an advanced oxidation technology shows unique advantages. The aim of this study was to explore the potential of electrochemical oxidation in the treatment of refractory organic wastewater and realize the effective degradation of various typical refractory organic compounds by constructing three-dimensional electrode systems and optimizing operating parameters. The experiment used titanium-based ruthenium dioxide electrode as anode material, which was systematically studied under different current density, electrolyte concentration and pH value. The results show that this method has significant removal effect on organic pollutants such as phenol and nitrobenzene, and the maximum removal rate can reach more than 95%. The innovation point is the introduction of pulse current mode, which effectively improves the energy utilization efficiency and reduces the amount of by-product generation. In addition, in situ Fourier transform infrared spectroscopy revealed the main intermediates in organic degradation and their transformation paths, which provided a theoretical basis for a deep understanding of the reaction mechanism.
