Abstract
The invention discloses an ultrafilter membrane for ultrafiltration apparatus. The ultrafilter membrane comprises a filter basic layer, a UV antibacterial layer, a fine hole filter layer, a support transition layer, and a carbon nanotube sponge layer. The UV antibacterial layer, the fine hole filter layer, the support transition layer, and the carbon nanotube sponge layer are sequentially arranged on the inner surface of the filter basic layer from inner to outer. Through the technical scheme mentioned above, the membrane will not be broken when being folded, the membrane is protected therefore, and moreover, the filtering is very sufficient.
Description
Technical field
The present invention relates to filter membrane field, particularly relate to a kind of ultrafilter membrane for ultrafiltration apparatus.
Background technology
Ultrafiltration (UltraFiltration, be called for short UF) be solution under pressure, solvent and part low molecular weight solutes arrive the opposite side of film through micropore on film, and solute polymer or other emulsifying micelle group are trapped, it is achieved the purpose separated from solution.Its separating mechanism is mainly by the sieving actoion of physics.It is during ultra-filtration and separation after feed liquid is applied certain pressure, polymer substance, colloidal substance are because of film surface and the primary sorption of micropore, in hole blocked and retain and three kinds of modes such as mechanical grading effect on film surface are stoped by ultrafilter membrane, and water and lower-molecular substance pass through film.Ultrafilter membrane is less than micro-filtration membrane aperture, at 0.7 ~ 7 kg/cm2Pressure under, can be used for separating diameter less than the molecule of 10 μm and microgranule.During ultrafiltration apparatus is widely used in Treated sewage reusing.
But, the ultrafilter membrane bending section having pressure when being currently used for ultrafiltration apparatus comes to harm and ruptures, and filters insufficient.
Summary of the invention
The technical problem that present invention mainly solves is to provide a kind of ultrafilter membrane for ultrafiltration apparatus, decreases film bending section having pressure when and comes to harm and rupture, thus plays the effect of protecting film, and filter the most abundant.
For solving above-mentioned technical problem, the technical scheme that the present invention uses is: provide a kind of ultrafilter membrane for ultrafiltration apparatus, including: filtering basic unit, ultraviolet antibiotic layer, pore filter course, support transition zone and CNT spongy layer, the described inner surface filtering basic unit is disposed with described ultraviolet antibiotic layer, described pore filter course, described support transition zone and described CNT spongy layer outward by interior.
In a preferred embodiment of the present invention, described support transition zone is ceramic fibre transition zone.
