Description

Technical Field

[0001] The utility model relates to an MBR membrane frame, in particular to a detachable MBR membrane frame. Background Art

[0002] MBR, also known as membrane bioreactor, is a novel water treatment technology that combines a membrane separation unit with a biological treatment unit. It primarily utilizes the MBR membrane to intercept macromolecular organic matter and biochemical sludge, allowing water molecules to pass through, thereby purifying wastewater. The MBR membrane is typically mounted on a membrane frame and coupled with an aeration system within the frame to perform the purification reaction. The purified water is then collected by a collection pipe.

[0003] The MBR membrane frame contains membrane curtain installation components, water collection components and aeration components. In order to more conveniently repair or replace the components during use, the components and the support frame need to be detachably installed and used. Therefore, a detachable MBR membrane frame is required.

[0004] The existing detachable MBR membrane frame uses bolts or rivets for detachable connection. When using bolts or rivets, it is necessary to open holes at the connection between the two so that the bolts or rivets can pass through the holes for connection. However, the opened holes will wear due to friction after long-term use, which will affect the fixation of the connection and lead to the problem of loose fixation after long-term use, and it is inconvenient to disassemble.
