Enough water fluxes are demonstrate,proved, wherein polyacrylonitrile fibre membrane has good antibacterial ability, can effectively inhibit the bacterium in water micro-
Biological pollution film, thin polymer film can effectively filter sulphion, chlorion, and ceramic matrix has good mistake to heavy metal
Filter acts on, and the three-dimensional netted filtration formed by three kinds of films can form filtration to the polluter in water, reach fast
The effect of fast water purification.
Further, first sintering carries out in vacuum atmosphere, 3 DEG C/s of heating rate, and it is small to be warming up to 400 DEG C of heat preservations 2
When, it is then warming up to 650 DEG C and keeps the temperature 4 hours；Second of sintering carries out under an argon atmosphere, and 5 DEG C/s of heating rate is warming up to
850 DEG C keep the temperature 10 hours；.
Further, the nano inoganic particle is aluminium oxide or titanium dioxide.The additive is coconut oil or olive
Oil.
Further, the nano inoganic particle and styrene-isoprene-styrene block copolymer, 18 carbon four
Olefin(e) acid, poly-internal-olefins weight ratio be (10-15):(30-45):(3-7):(9-13).
Further, the weight ratio of the intermediary and sulfonated polyether sulfone powder, additive is (1-1.1):(3-6):
(0.2-0.4)。
Beneficial effects of the present invention：The high stability sewage water filtration composite membrane water-flowing amount compared with prior art of the present invention
Height, the substance classes that may filter that are more, and are not easy to be contaminated, and achieved the effect that high-efficient purification water quality.
