Description

Technical Field

[0001] The utility model relates to the technical field of electrocatalytic oxidation, and particularly relates to a generating device for efficient tubular electrocatalytic oxidation. Background Technique

[0002] Electrocatalytic oxidation technology refers to initiating a series of electrochemical reactions by applying an electric current to an electrode. During the reaction process, the electrons generated on the electrode surface and oxidants (such as hydrogen peroxide, oxygen, ozone, etc.) act together to oxidize and decompose organic pollutants in wastewater into harmless substances such as carbon dioxide and water. With the acceleration of industrialization and urbanization, the wastewater discharge is increasing continuously, and wastewater treatment has become an important topic in environmental protection. Traditional wastewater treatment methods such as biological treatment and chemical precipitation have many limitations in treating high-concentration and refractory organic wastewater. Therefore, it is particularly important to develop efficient and environmentally friendly wastewater treatment technologies. As an application form of electrocatalytic oxidation technology, the tubular electrocatalytic oxidation generating device has attracted much attention due to its compact structure and high treatment efficiency. Through the electrocatalytic oxidation reaction, organic pollutants in wastewater are efficiently degraded into harmless substances. For some wastewater that is difficult to be directly biodegradable, electrocatalytic oxidation technology can convert it into substances that are more easily biodegradable, providing favorable conditions for subsequent biological treatment.

The electrocatalytic oxidation decontamination device provided by the utility model adopts the structure of spraying a titanium suboxide intermediate layer on the surface of the titanium substrate, so that the matching between the titanium substrate and the titanium suboxide is appropriate, and the intermediate layer and the substrate show a state of mutual penetration and mutual biting. In this way, to a certain extent, the passivation process caused by the penetration of oxygen atoms into the substrate is slowed down, and at the same time, the bonding force between the intermediate layer and the substrate is significantly enhanced, and the electrocatalytic effect is good.
