The invention relates to a charged membrane device for
water processing. The device comprises a power supply, a membrane group device and a membrane
assembly, wherein the membrane group device is groove-shaped, the upper portion and the lower portion of the membrane group device are open and the periphery of the membrane group device is sealed, the membrane
assembly is arranged inside the membrane group device, and the outer surface of a
hollow fiber membrane wire is coated with a layer of outer tubular supporting layer having a mesh multi-hole structure to form a
hollow fiber membrane. When the device is applied in an immersion type membrane
separation technology, under the action of current of the power supply, the
hollow fiber membrane wire is shielded by the negative
electrode of the outer tubular supporting layer, and pollutants with negative
electricity can hardly pollute the hollow
fiber membrane under the action of electrostatic repulsive force and the
flocculation of an
electrode dissolution flocculating agent, so that membrane
pollution is controlled. The charged membrane device having an anti-
pollution function and capable of generating the flocculating agent can control membrane
pollution effectively and has the advantages of being high in
stain resistance, high in strength of the membrane wire, free of addition of the flocculating agent, capable of purifying waterquality, practical and the like.
