Novel comet type composite fiber filtering material

Abstract

The invention belongs to the field of fiber filtering material and particularly relates to a novel comet type composite fiber filtering material. The novel comet type composite fiber filtering material comprises a comet nucleus and a comet tail connected on the comet nucleus, wherein the comet tail is a fiber filament bundle consisting of fiber filaments; and the fiber filament bundle consists of at least two types of fiber filament materials. The composite fiber filtering material can improve the knotting phenomenon of the fiber filaments well, plays a role in filtering and blocking dirt in water in a better way, enhances filtering accuracy and water environmental capacity, has high filtering material cleanliness after backwashing, and saves energy and water.

Description

(1) Technical field

[0001] The invention belongs to the field of fiber filter materials, in particular to a novel comet type composite fiber filter material. (2) Background technology

[0002] In the field of water treatment, the separation of suspended particles and water is a very critical link. The traditional separation process uses granular filter media, but the disadvantages are low filtration precision, low filtration speed, and small dirt holding capacity of the filter bed. Then use synthetic fiber and its formed body filter material, which can make up for the defects of particle filter material, but the specific gravity difference between fiber and water is small, resulting in poor cleaning effect, and the fiber is easy to lose during backwashing. Later, various synthetic fiber forming filter materials were proposed, and comet fiber filter material is one of them. The traditional comet-type fiber filter material has a comet nucleus at one end and a comet tail at o...
