The electrochemical oxidation method is a common industrial wastewater treatment method for the advanced treatment of organic pollutants. It is an effective way to degrade organic pollutants and reduce organic pollutants in wastewater. In this method, the organic pollutants in the wastewater are transformed into carbon dioxide and water under the action of electrochemical reaction to reach the purpose of water purification.
The electrochemical oxidation method is based on the electrochemical oxidation reactions of organic pollutants in wastewater under the effect of electric field. When the electric field is applied, the organic pollutants in the wastewater form anions, and then the organic pollutants undergo oxidation-reduction reactions at the electrodes. During the electrochemical oxidation process, pollutants are reduced in the anode, while oxygen is oxidized in the cathode. This reaction otherwise known as oxidation-reduction interaction, is conducive to the degradation of organic pollutants, and eventually results in the transformation of organic pollutants into carbon dioxide and water molecules.
In addition to the oxidation-reduction reaction, the electrochemical oxidation method can also further the process of mineralization of pollutants by introducing chemicals and reacting with electrochemical reactions. The resultant products are usually stable in nature and can eventually be removed from the wastewater through process filtration or other means. By using the electrochemical oxidation technology, wastewater can be treated to a sufficient high quality to meet the requirements of discharge standards in many industries, thus becoming an important wastewater treatment method.
What’s more, the electrochemical oxidation method is advantageous in that it is simple to operate and control, and it can be adapted to an array of wastewater treatment and odor control technologies. Compared to other oxidation technologies, such as the use of chemical reagents and air bubbling, the electrochemical oxidation method requires less energy, is more economical and efficient, and can be used to treat wastewater containing high concentrations of organics, sulfur and nitrogen. It also has few organic byproducts in the end products.
Finally, electrochemical oxidation technology can be used both in large-scale industrial wastewater treatment systems and in small-scale distributed wastewater treatment systems. There are a few different types of electrochemical oxidation technology available, including rotating electrode process and anolyte-based electrochemical oxidation technology. Depending on the characteristics of the wastewater and the type of pollutants present, the industry can choose the correct type of electrochemical oxidation technology to achieve the desired results.
Overall, electrochemical oxidation technology is a powerful wastewater treatment technology which is able to tackle a wide range of wastewater treatment issues. It is particularly useful for the removal of highly toxic, organic and odorous substances, and can be utilized in both small and large-scale wastewater treatment systems. It provides a cost-effective, efficient solution to many industries, making it a popular choice for industrial wastewater treatment.
