[0033] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, unless otherwise specified, "plurality" means two or more.

[0034] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0035] As mentioned in the background art, many industrial wastewaters contain a large amount of refractory organic matter, which is highly resistant to biological treatment processes, making it difficult for traditional biological treatment methods to achieve ideal treatment effects.

[0036] In order to improve the above problems, this application proposes an electrocatalytic oxidation device for improving the biodegradability of sewage, which improves the efficiency and environmental performance of sewage treatment through advanced treatment technology. The core advantage of this device is that it can effectively reduce the use of chemicals, thereby reducing the potential impact on the environment. Compared with traditional chemical treatment methods, this equipment provides a greener solution. Through carefully designed cathode columns and anode columns, the device uses the principle of electrocatalytic oxidation to convert difficult-to-biodegrade organic matter into substances that are easy to biologically treat. This process not only improves the biodegradability of sewage, but also creates favorable conditions for subsequent biological treatment processes, thereby improving the entire sewage treatment process. In order to further enhance the treatment effect, the device is equipped with an air intake assembly in the tank body. By introducing oxygen into the tank body, the decomposition of difficult-to-degrade organic matter can be promoted, making it easier to be treated by subsequent biological processes. At the same time, the design of multiple gas nozzles ensures that the wastewater flows fully under the action of bubbles, which not only promotes the reaction and degradation of pollutants in the wastewater, but also helps to improve the uniformity and efficiency of the treatment. In order to ensure the quality of the wastewater entering the tank body, the device is equipped with a water intake assembly on the top of the tank body. This design allows the wastewater to be effectively filtered before entering the tank body, removing suspended matter and other impurities that may affect the electrocatalytic oxidation process, thereby ensuring the smooth progress of the treatment process.
