Abstract
Electrochemical oxidation technology, as an advanced oxidation process, demonstrates unique advantages in the treatment of organic wastewater, enabling the mineralization of recalcitrant organic compounds that are difficult to degrade using traditional biological and physicochemical methods. This study aims to investigate the performance and mechanisms of electrochemical oxidation technology in treating different types of organic wastewater, providing theoretical basis and technical support for practical engineering applications. Laboratory-made two-dimensional and three-dimensional electrode reactors were employed, with multiple typical organic pollutants selected as research subjects. The effects of operational parameters such as current density, electrolysis time, and pH value on the electrochemical oxidation process were examined. Modern analytical instruments were utilized for qualitative and quantitative analysis of intermediate products. Results indicate that electrochemical oxidation technology can efficiently remove organic pollutants, with removal efficiency significantly increasing as current density rises; the three-dimensional electrode system exhibits higher treatment efficiency compared to the two-dimensional electrode system. Degradation pathways of organics vary under different pH conditions. Innovatively, machine learning algorithms were introduced into the modeling and optimization of the electrochemical oxidation process, achieving effective prediction of complex nonlinear relationships and offering new insights for parameter optimization of electrochemical oxidation technology. The study reveals that electrochemical oxidation technology holds broad application prospects in organic wastewater treatment and can serve as an effective complement or alternative to traditional treatment methods.
