Description

Technical Field

[0001] The utility model relates to the technical field of electrocatalysis, in particular to an electrocatalytic oxidation device. Background Art

[0002] There are a large number of complex organic pollutants in industrial organic wastewater, which are highly toxic and difficult to treat, and require high treatment technology. This type of wastewater has poor biodegradability. After being treated by traditional microbial treatment systems, some toxic and difficult-to-degrade pollutants still exist in the wastewater, which cannot be directly discharged or recycled. Therefore, the wastewater needs to be further treated in depth. The main technology for deep treatment of industrial organic wastewater is advanced oxidation technology, which degrades or completely mineralizes the difficult-to-degrade organic matter in the wastewater by generating hydroxyl free radicals. Currently, electrochemical oxidation is one of the most commonly used technologies in advanced oxidation. It uses electrons, a clean energy source, as a catalyst, and uses anode and cathode electrode materials as a medium to degrade organic pollutants by direct oxidation and indirect oxidation.

[0003] During the operation of the system, numerous flocculent particles formed on the electrode plates will adhere to the space between the two plates, reducing the effective area of ​​the plates and thus weakening the electrolysis efficiency of adjacent plates. In order to facilitate the cleaning of the flocculent particles between the plates, this scheme proposes an electrocatalytic oxidation device. Utility Model Content
