Description

Technical Field

[0001] The utility model relates to the technical field of MBR membrane cleaning, in particular to an MBR membrane cleaning and recycling device. Background Art

[0002] MBR membrane is an activated sludge filtration membrane used in the field of sewage treatment. When the existing MBR membrane is used, the MBR membrane is concentrated in a membrane pool and immersed in sewage. The suction pump continuously pumps water, and a negative pressure is formed in the middle of the MBR membrane. The sewage is filtered through the MBR membrane, and water molecules pass through the membrane wall and enter the water production side and are discharged through the pumping holes. Pollutants are trapped outside the membrane wall. When the existing MBR membrane is used, the filtrate and impurities will accumulate on the surface of the MBR membrane, and the MBR membrane needs to be cleaned regularly for subsequent use.

[0003] Chinese patent CN213019391U discloses an MBR membrane cleaning device, which discloses a technical solution that saves cost, time and effort, and solves the problem that the existing MBR membrane cleaning is usually carried out by continuously aerating under the MBR membrane, and the sludge and dirt on the surface of the MBR membrane are flushed by gas-liquid two-phase flow, or the production needs to be stopped regularly, the MBR membrane assembly is lifted out of the water, and manually flushed with a high-pressure water gun.

[0004] However, when the device is in use, the MBR membrane is cleaned only by a membrane brush, which easily leads to insufficient cleaning of the MBR membrane. A large amount of residues are still retained on the MBR membrane, reducing the cleaning effect. Therefore, a new MBR membrane cleaning device is proposed to solve the above problem.
