Problems solved by technology

[0002] The existing flat membrane is only welded to the deflector on the four sides, which leads to the existing flat membrane not being resistant to backwashing. During backwashing, the membrane keeps bulging like blowing a balloon, and the filter membrane at the edge welding is easy to tear
Because it is not resistant to backwashing, it is limited that it cannot be designed for backwashing, which seriously affects the fouling resistance of the membrane and the stability of the sewage treatment system, and also indirectly speeds up the chemical cleaning frequency of the membrane, increasing the cost of chemicals and cleaning labor cost

Embodiment Construction

[0017] In order to make the technical means, creative features, objectives and effects of the invention easy to understand, the present invention will be further elaborated below in conjunction with specific illustrations.

[0018] A preferred embodiment of the present invention is to provide a kind of anti-backwashing flat membrane, the purpose is to set anchor points for fixing the filter membrane on both sides of the deflector, the anchor points are evenly set to fix the filter membrane, so that the flat membrane can It can improve the anti-fouling resistance while being resistant to backwashing, ensure the water output, reduce the frequency of chemical cleaning of the flat membrane, save the cost of chemicals and labor costs, and has a simple structure and is easy to use.

[0019] Such as figure 1 As shown, a backwash-resistant flat membrane, including a deflector 101 and a filter membrane 102, the filter membrane 102 is connected to the deflector 101 through a plurality o...

Abstract

The invention discloses a backwash-resistant flat sheet membrane which comprises a guide plate and a filter membrane. The filter membrane is connected to the guide plate through a plurality of anchorpoints, the distance between every two adjacent anchor points is consistent, and a water discharging pipe is connected to the guide plate.

Description

technical field [0001] The invention relates to the technical field of liquid filtration devices, in particular to a backwash-resistant flat membrane and a preparation method. Background technique [0002] The existing flat membrane is only welded to the deflector on the four sides, which leads to the existing flat membrane not being resistant to backwashing. During backwashing, the membrane keeps bulging like blowing a balloon, and the filter membrane at the edge welding is easy torn. Because it is not resistant to backwashing, it is limited that it cannot be designed for backwashing, which seriously affects the fouling resistance of the membrane and the stability of the sewage treatment system, and also indirectly speeds up the chemical cleaning frequency of the membrane, increasing the cost of chemicals and Cleaning labor costs. Contents of the invention [0003] The technical problem to be solved in the present invention is to provide a backwash-resistant flat membra...
