Description

MBR membrane frame

technical field

The utility model relates to water treatment technology, in particular to an MBR membrane frame.

Background technique

MBR (Membrane Bioreactor) is a new type of efficient sewage treatment equipment that organically combines membrane separation technology with traditional sewage biological treatment processes. The MBR process mainly uses membrane separation technology to intercept active bacteria and macromolecular organic substances in sewage, which can effectively achieve solid-liquid separation, greatly improve the quality of effluent water, and reduce the volume of the reactor. MBR membrane module is the key component of MBR, its main function is to intercept active bacteria, improve reactor efficiency, shorten reaction time and improve high-quality effluent.

The MBR membrane frame is the supporting frame of the MBR membrane, and the transportation and collection of the produced water and backwash water of the MBR membrane are realized by pipeline transportation. The previous generation of MBR membrane racks has been used until now, and there are the following defects and deficiencies: 1. The production water and backwash water of the MBR membrane are transported and collected by the supporting structural beams of the membrane racks, which will cause welding joints between the structural beams Corrosion is serious, and the internal pressure of the beam body is uneven, which causes the membrane frame to leak; 2. Due to the different materials of the joints connecting the MBR membrane and the membrane frame, the material of the joints of the MBR membrane is ABS, and the material of the joints of the membrane frame is SS304, resulting in The thread opening of the joint is severely worn, causing water leakage from the membrane frame, which seriously affects the water quality of the produced water; 3. During the use of the MBR system, due to the suction of the produced water pump and the effect of blowing aeration, the MBR diaphragm will vibrate, and at the same time Since the connection between the MBR membrane and the membrane frame is a rigid connection, the wear of the joint between the MBR membrane and the membrane frame is accelerated; 4. A piece of MBR membrane has a total of 4 ends fixed on the upper and lower beams of the MBR membrane frame, of which 2 The ends are connected by wire ports, and the other two ends are non-fixed socket connections. When the diaphragm is running jittery, only the two ends connected by wire ports play a fixed role, thus causing the membrane frame to The uneven stress and the accelerated wear of the joint thread mouth, and at the same time make the diaphragm loose and there is a risk of falling off.
