Description

Technical Field

[0001] The utility model relates to the technical field of landfill leachate, in particular to an oxidation device for the concentrated water of landfill leachate membrane treatment. Background Art

[0002] An oxidation device for the concentrated water of landfill leachate membrane treatment is a device specifically used for treating the concentrated water generated after the landfill leachate is treated by a membrane. Such an oxidation device usually adopts advanced oxidation technologies, such as Fenton oxidation, ozone oxidation, electrocatalytic oxidation, etc., to degrade the refractory organic matters and harmful substances in the concentrated water. An electrocatalytic oxidation device generates strong oxidizing substances, such as hydroxyl radicals, by applying an electric field to cause redox reactions on the electrode surface, thereby decomposing organic matters into harmless substances such as carbon dioxide and water.

[0003] The prior art such as the utility model with the publication number of CN220845674U relates to the technical field of sewage treatment, in particular to an electrocatalytic oxidation device for landfill leachate. It mainly aims at the problem that the cleaning sleeve in the existing device is located inside the machine body for a long time, which easily allows landfill leachate to enter the cleaning sleeve, causing impurities of the landfill leachate to adhere to the inner wall of the cleaning sleeve, thereby reducing the practicality of the cleaning sleeve effect. Since the landfill leachate is corrosive, it is easy to reduce the fit degree between the cleaning sleeve and the electrode surface, affecting the cleaning effect. The following technical solutions are proposed: including a machine body, an electrode is installed on the inner wall of the top of the machine body, and a movable component that can move is arranged below the electrode. The utility model realizes the cleaning of the electrode while avoiding the influence of the corrosiveness of the landfill leachate on the cleaning effect, and during the cleaning process, only one-way pulling is required, which is beneficial to reducing physical exertion, and solves the problem that the cleaning sleeve in the device is located inside the machine body for a long time, which easily allows landfill leachate to enter the cleaning sleeve, causing impurities of the landfill leachate to adhere to the inner wall of the cleaning sleeve, thereby reducing the practicality of the cleaning sleeve effect. Since the landfill leachate is corrosive, it is easy to reduce the fit degree between the cleaning sleeve and the electrode surface, affecting the cleaning effect.

[0004] In daily work, it is found that when the existing oxidation device for the concentrated water of leachate membrane treatment is in use, although it can be cleaned, some tiny solid particles, fibers and other impurities are likely to enter the device. The wear, blockage and corrosion of the device components lead to inconvenient subsequent cleaning and easily affect the oxidation efficiency, and further cause the problem that the existing concentrated water oxidation device is prone to enter impurities, resulting in inconvenient blockage cleaning and affecting the oxidation efficiency.
