CQDHX Series Electrochemical Advanced Oxidation Technology
Cutting-edge Electrode Manufacturing Technology
For 15 years starting in 2010, we have dedicated ourselves to researching electrode manufacturing and application. Through over 3,000 iterations of electrode manufacturing verification and more than 5,000 experiments on various types of highly complex wastewater, we have integrated the characteristics of diverse challenging wastewaters. By adjusting the composition of the electrode substrate materials, the constituents of the electrode surface materials, and the electrode surface deposition and formation conditions, we have achieved optimal performance for treating different kinds of highly complex wastewater. The CQDHX series electrode modules can meet the requirements for treating highly complex industrial wastewater under extreme conditions, effectively removing organic COD, ammonia nitrogen, toxic substances, bacteria, color, phosphorus, and various heavy metals from hard-to-degrade industrial organic wastewater with high salinity, high toxicity, high concentration, and strong acidity/alkalinity.
Working Mechanism of CQDHX Series Electrode Modules
Electrochemical oxidation is a technology that utilizes an applied electric field to drive chemical reactions for pollutant degradation. Its core reaction occurs at the anode of the electrolytic cell, and the operating mechanisms are primarily categorized into two types: direct oxidation and indirect oxidation, which often function synergistically.
Direct Oxidation Mechanism: Pollutant molecules migrate to and adsorb onto the anode surface. Subsequently, the anode, acting as an electron acceptor, directly extracts electrons from the pollutant molecules, causing their oxidative decomposition. This process is controlled by the mass transfer rate and relies on the catalytic activity and adsorption properties of the anode material, exhibiting a certain degree of selectivity towards different pollutants.
Mechanism of Indirect Oxidation: The anode does not directly oxidize pollutants. Instead, it generates highly oxidizing agents by electrolyzing components within the solution. These agents then diffuse into the bulk solution and carry out homogeneous oxidation of the pollutants. Depending on the type of oxidants generated, the main pathways can be categorized as follows:
|
Hydroxyl Radical Pathway |
At the surface of an anode with high oxygen evolution overpotential, water or hydroxide ions are electrochemically oxidized to generate hydroxyl radicals. Hydroxyl radicals possess an extremely high oxidation potential and can non-selectively oxidize the vast majority of organic compounds, ultimately mineralizing them into carbon dioxide, water, and small inorganic molecules. This pathway achieves the most thorough degradation. |
|
Reversible Redox Mediator Pathway |
Specific metal ions in the electrolyte are oxidized at the anode to higher valence states, forming strong oxidants (such as high-valent metal ions). These oxidants diffuse into the solution to oxidize pollutants and, after being reduced to their initial valence states, can return to the anode surface to be re-oxidized, thus forming a cycle. |
|
Other Oxidant Pathways |
Through electrode design and regulation of reaction conditions, hydrogen peroxide can be generated at the cathode, or ozone can be produced at specific anodes. Hydrogen peroxide can combine with ferrous ions to form an electro-Fenton system, which subsequently generates hydroxyl radicals, thereby enhancing oxidation efficiency. |
Electrochemical oxidation achieves pollutant degradation through two main mechanisms: electron transfer at the anode surface and the in-situ generation of highly oxidizing species. In practical applications, particularly for complex wastewater systems, direct and indirect oxidation often work synergistically. By optimizing electrode materials and process parameters, efficient and advanced treatment of organic pollutants can be achieved.
