Description
Technical field
The present invention relates to water-treatment technology field, and in particular to a kind of purpose ceramic-film filter and preparation method thereof.
Background technology
With the improvement of people's living standards and the pay attention to day by day to water body environment protection, purpose ceramic-film filter is more and more
Be applied to water-treatment technology field.Seal casinghousing and ceramic membrane are two big composition components in purpose ceramic-film filter, capsul
Body is provided with wastewater inlet, outlet of sewer and clear water output, and wastewater inlet is connected with ceramic membrane one end, outlet of sewer and ceramic membrane
The other end connects, and clear water output is arranged on seal casinghousing, for discharging the clear water through ceramic membrane filter.
Existing ceramic membrane mostly is the loose structure of potter's clay firing, and intensity is not enough, easily damages in use, cleaning process
Bad, service life is shorter.
And, the microorganism in sewage is easily bred in ceramic membrane, causes the Pore Blocking of ceramic membrane.
Content of the invention
It is an object of the invention to provide a kind of purpose ceramic-film filter and preparation method thereof.
One of for achieving the above object, the present invention is adopted the following technical scheme that：
A kind of purpose ceramic-film filter, including seal casinghousing and the ceramic membrane being arranged in the seal casinghousing；
The ceramic membrane includes the porous type embryo using kieselguhr sintering, and the porous type embryo surface is attached with oxidation
Aluminium lamination and the nano-metal particle containing metal ion.
Used as further improved technical scheme of the present invention, the metal ion is silver ion, the nano-metal particle
For nano-Ag particles.
Used as further improved technical scheme of the present invention, the aperture of the porous type embryo is 300-610 nanometer, the pottery
The aperture of porcelain film is 1-50 nanometer.
For realizing the another object of foregoing invention, the present invention is adopted the following technical scheme that：
A kind of preparation method of purpose ceramic-film filter, comprises the following steps：
S1, by kieselguhr sintering make porous type embryo；
S2, to porous type embryo electrodeposition coated film and dry, sintering, to adhere to alumina layer in the porous type embryo surface；
S3, the porous type embryo for being attached with alumina layer is immersed in nano-metal particle aqueous solution, after taking-up through
Dry, sinter, cooling obtains final product ceramic membrane；
S4, ceramic membrane is assemblied in seal casinghousing, obtains final product purpose ceramic-film filter.
As further improved technical scheme of the present invention, using alumina sol as electrophoretic deposition liquid in step S2.
Used as further improved technical scheme of the present invention, in step S3, nano-metal particle aqueous solution is nanometer silver
Grain aqueous solution.
With respect to prior art, the method have technical effect that：
The ceramic membrane of the present invention has the vegetative function of suppression, and smooth surface, intensity height, and can wash away repeatedly makes
With long service life.
Description of the drawings
Fig. 1 is the schematic flow sheet of the preparation method of purpose ceramic-film filter in an embodiment of the present invention.
Specific embodiment
Describe the present invention below with reference to specific embodiment shown in the drawings.But these embodiments are simultaneously
The present invention is not limited, structure that one of ordinary skill in the art is made according to these embodiments, method or functionally
Conversion is all contained in protection scope of the present invention.
A kind of purpose ceramic-film filter, including seal casinghousing and the ceramic membrane being arranged in the seal casinghousing；
The ceramic membrane includes the porous type embryo using kieselguhr sintering, and the porous type embryo surface is attached with oxidation
