Abstract

The invention discloses an externally pressed six-wing tubular membrane and a method for manufacturing the membrane. The externally pressed six-wing tubular membrane comprises a six-wing tubular membrane body, a six-wing lined pipe, a composite filter membrane, a depression bar, a core tube, an electrode lead, an external layer carbon net, an organic filter membrane, an internal layer carbon net, and a prefabricated membrane tube. The composite filter membrane is composed of the internal layer carbon net, the organic filter membrane, the external layer carbon net and the electrode lead. The six-wing membrane is composed of the six-wing lined pipe, the composite filter membrane, the depression bar, the core tube and an end cover; flow guide circular holes are arranged between adjacent wing boards outside the core tube; the composite filter membrane is fixed between two adjacent wing boards by the depression bar and distributed on the outer surface of the six-wing lined pipe in a rising and falling way; both ends of the six-wing tubular membrane are sealed and fixed by the end cover and an epoxy resin; the electrode lead is led out from the sealed position of the epoxy resin. According to the externally pressed six-wing tubular membrane, the high-efficiency filtration, and pollution-preventing and self-cleaning functions are realized, and the manufacturing process is simple, thus the externally pressed six-wing tubular membrane is applied to the large polluted water or waste water treatment engineering.
