Over the years, industry, agriculture and other human activities have discharged large amounts of organic pollutants into landfills. Among them, color-resistant dissolved organic pollutants have attracted great attention. In order to achieve the safe discharge of wastewater, a variety of treatment technologies have been used to effectively eliminate CDOM in water. In this paper, the most promising electrochemical oxidation (EO) techniques are reviewed, their basic principles are introduced, and the research progress and application status of electrode materials and electrochemical reactors are introduced. At the same time, the substance composition and detection method of CDOM are discussed. Finally, the performance of EO technology to remove CDOM is summarized. However, we should note that electrode optimization has always been the core of EO technology improvement, and the combination of updated electrode material iteration and treatment process has broad prospects for the wide application of EO technology.
