Netted hydrophobic aeration membrane water body purification device of water -curtain -type

The utility model discloses a netted hydrophobic aeration membrane water body purification device of water -curtain -type, including spud pile and a plurality of water -curtain -type of group membranemodule. Seted up the gas passage in the spud pile, the gas passage passes through intake -tube connection to outside air feeder. The water -curtain -type membrane module is including admitting air end and hollow fiber curtain, and the end of admitting air is fixed and is linked together on the spud pile and with the gas passage. The hollow fiber curtain is woven through the braided wire rule by aplurality of vacuum fibre membrane and is formed, the one end and the sealed intercommunication in end that admits air of vacuum fibre membrane, and the other end is the blind end, and the vacuum fibre membrane has a plurality of aeration hole along the length direction equipartition. Does vacuum fibre outer surface of the film cladding have the hydrophobic contact angle of one deck to be 90- 150the hydrophobic film. The
