Then sieving is pressed into sheet by mill, sieving, carry out first sintering, obtain porous ceramics base material；By nano inoganic particle with
Styrene-isoprene-styrene block copolymer, parinaric acid, poly-internal-olefins are added in deionized water, are surpassed
After sound dispersion, heating water bath is evaporated until aqueous solvent, obtains intermediary；Treated intermediary and sulfonated polyether sulfone powder
End, additive are blended in batch mixer, then, by spinneret, will be woven into polymer after mixture melting extrusion with extruder
Film；Using porous ceramics basement membrane as base material, after carbon-fiber film and thin polymer film is respectively set in two sides, presses, then carry out altogether
Second of sintering forms sewage water filtration composite membrane after cooling.
Highdensity aquaporin is all had in porous ceramics basement membrane, carbon-fiber film and thin polymer film, it is ensured that enough
Water flux, wherein carbon-fiber film can effectively filter sulphion, chlorion and organic matter, and ceramic matrix has heavy metal
Good filtration, the three-dimensional netted filtration formed by three kinds of films can form the polluter in water filtering and make
With achieving the effect that Quick purifying.
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：Water-flowing amount is high compared with prior art for the sewage disposal composite membrane of the present invention, and can be with
Heavy metal ion, sulphion in disposable removal sewage, chlorion, organic matter, achieve the effect that high-efficient purification water quality.
