DEVICE FOR TREATMENT OF WASTE LIQUID HAVING SUBMERGED MEMBRANE OF SPIRAL WOUND TYPE

摘要

The present invention relates to a waste fluid treatment device with a spiral wound type submerged membrane. The waste fluid treatment device with the spiral wound type submerged membrane comprises a water tank in which a waste fluid flows and is discharged by being filtered; a waste fluid inlet which supplies the waste fluid into the water tank; a submerged membrane which is placed inside the water tank in a ring shape and filters foreign substances included in the waste fluid flowing through the waste fluid inlet; a permeate suction unit which sucks permeate of the waste fluid passing through the submerged membrane and supplies the permeate to the outside of the water tank; an air supply unit which supplies compressed air to the submerged membrane and prevents the foreign substances from being attached to the surface of the submerged membrane; and a membrane support porous plate which supports the lower part of the submerged membrane and has a plurality of holes on the surface.
