Hydrophobic aeration membrane and subassembly thereof

The utility model discloses a hydrophobic aeration membrane, including hollow fiber membrane and the hydrophobic film of cladding at the hollow fiber membrane surface. Hydrophobic aeration membrane has a plurality of aeration holes along the length direction equipartition, is the interval that links to each other between two aeration holes 1 100um, is the aperture in aeration hole 100 800nm, is the hydrophobic contact angle of hydrophobic film 90 150. A hydrophobic aeration membrane subassembly is still disclosed, including membrane module and a plurality of hydrophobic aeration membrane. Themembrane module is woven through the braided wire rule and is in the same place with the sealed intercommunication in end that exhausts, a plurality of hydrophobic aeration membrane with the end of admitting air respectively including the end and the end of exhausting of admitting air, hydrophobic aeration membrane's both ends. The utility model provides a hydrophobic aeration membrane have the hydrophobicity good, arrang
