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.

For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] As mentioned in the background technology, traditional methods for treating organic phosphorus mainly include physical adsorption, chemical oxidation, biodegradation, etc. However, these methods have problems such as low treatment efficiency, high cost, and secondary pollution.

[0040] In order to improve the above-mentioned problems, the present application proposes an electrocatalytic oxidation device for organic phosphorus conversion, which has significant innovation and practicality. An ultraviolet lamp and an electrode assembly are specially configured inside the tank body. The two can work together to provide sufficient light energy, thereby activating the photocatalyst and further generating a large number of free radicals. These free radicals have strong oxidizing ability and can effectively oxidize organic phosphorus into inorganic phosphorus, thereby realizing efficient conversion of organic phosphorus. This process not only improves the conversion rate of organic phosphorus, but also helps to reduce the potential harm of organic phosphorus to the environment. In addition, the design of the tank body also fully considers the needs of the reaction process. It provides a place suitable for the reaction. Its properties directly affect the catalytic efficiency and the selectivity and stability of the reaction. By optimizing the design of the tank body, the efficiency and stability of the reaction can be further improved to ensure that the reaction can be carried out under optimal conditions. In order to facilitate the replacement and maintenance of the electrode assembly, two third openings are designed on the top of the tank body. These two openings enable the electrode assembly to freely extend into or out of the tank body, which greatly facilitates the replacement and maintenance of the electrode assembly, extends the service life of the equipment, and reduces maintenance costs.
