5. The growth desorption type filter membrane for sewage treatment according to claim 4, which is characterized in that: the deformation layer (1001) is made of rubber, a plurality of uniformly distributed magnetic isolation powder are embedded in the deformation layer (1001), and the content of the magnetic isolation powder is 80%.
6. The growth desorption type filter membrane for sewage treatment according to claim 4, which is characterized in that: the adsorption layer (1002) is made of sponge materials, and lubricating oil is filled in the adsorption layer (1002).
7. The growth desorption type filter membrane for sewage treatment according to claim 5, which is characterized in that: the magnetic isolation powder is made of iron-nickel alloy materials, and the content of nickel in the magnetic isolation powder is 80%.
8. A growth desorption type filter membrane for sewage treatment according to claim 3, characterized in that: the thorn-shaped powder injection (16) is arranged in a shape of two pointed surfaces, and the upper end of the thorn-shaped powder injection (16) is fixedly connected with a magnetic end (1601).
9. The use of a growth desorption type filter membrane for wastewater treatment according to any one of claims 1 to 8, wherein: the method comprises the following steps:
s1, the impact of the sewage on the fixed filtering membrane (2) during flowing can promote the carbon dioxide in the carbon dioxide aqueous solution in the pneumatic storage cylinder (4) to escape;
s2, the pneumatic push ball (7) can be pushed to move upwards along the pneumatic storage cylinder (4) along with the gradual increase of the carbon dioxide gas, the air pressure in the rubber sealing sleeve (5) is improved, the rubber sealing sleeve (5) is promoted to prop up the movable filtering membrane (3) on the outer side of the rubber sealing sleeve, when the pneumatic push ball (7) contacts the anti-falling ring (14), part of the carbon dioxide can be promoted to push the rubber sealing sheet (12) open and then enter the pneumatic push ball (7) along with the gradual release of the carbon dioxide, and the expansion of the pneumatic push ball (7) is assisted;
s3, the magnetic shielding state of the built-in magnet ball (13) can be released by means of continuous expansion of the pneumatic push ball (7), so that the pneumatic push ball (7) is pushed to slide downwards by means of repulsion between the built-in magnet ball (13) and the anti-falling ring (14), and carbon dioxide is pushed to be dissolved in water again;
s4, the rubber sealing sleeve (5) and the dynamic filtering membrane (3) can be caused to shrink along with the reduction of the air pressure in the rubber sealing sleeve (5), so that the dynamic change from the support to the shrink of the dynamic filtering membrane (3) is completed, and the dynamic change along with the dynamic filtering membrane (3) is carried out continuously and circularly.
