Description
Technical field
The utility model relates to photocatalysis membrana technical fields, and in particular to a kind of photocatalysis composite membrane.
Background technique
Water pollution has drastically influenced people's lives quality, in order to improve the living environment of the mankind, it is necessary to dirt
Water is effectively treated.
Dyeing waste water is the waste water of printing and dyeing mill's discharge based on processing cotton, fiber crops, chemical fibre and its blending product.Printing and dyeing are useless
Water water is larger, 1 ton of every dyeing and printing process, 100~200 tons of textile water consumption, wherein 80~90% become waste water.Textile printing and dyeing wastewater
Have the characteristics that water is big, organic pollutant content is high, alkalinity is big, change of water quality is big, belongs to one of intractable industrial wastewater, give up
Contain dyestuff, slurry, auxiliary agent, finish, soda acid, fiber impurity, sand substance, inorganic salts etc. in water.
At present for there are many kinds of sewage treatmentmethods, photocatalysis treatment is a kind of sewage treatment just to grow up recently
Mode, but photocatalysis is used for sewage treatment and not mature enough at present, concrete application is also not enough extensively.
Summary of the invention
Purpose of the utility model is to solve current photocatalysis there is a problem of mentioning using deficiency for sewage treatment
For a kind of photocatalysis composite membrane.
In order to reach above-mentioned purpose of utility model, the utility model uses following technical scheme：
A kind of photocatalysis composite membrane, including polymeric matrix film and the cuprous oxide being dispersed in polymeric matrix film
The partial size of particle or the cuprous oxide powder last layer for being dispersed in polymeric matrix film surface, cupric oxide powder is less than or equal to 100
Nanometer.
Preferably, cuprous oxide is dispersed in polymeric matrix film, evenly dispersed in polymeric matrix film
There is reticular fibre, cuprous oxide is carried on reticular fibre.
Preferably, the composite membrane with a thickness of 0.1-2 microns.
Preferably, the composite membrane is perforated membrane, i.e., composite membrane is porous structure.
Preferably, the aperture is 0.1-1 microns, and the porosity is 20%-50%.
Preferably, the polymeric matrix film is polypropylene nonwoven film.
Preferably, the polymeric matrix film with a thickness of 5-20 microns.
For the photocatalysis composite membrane with two kinds of structures, first is that cuprous oxide powder is blended to carry out composite membrane with polymer
Preparation, finally obtains composite membrane, which is formed porous structure, under light illumination, has good degradation；
Second is the surface formation cuprous oxide powder last layer for dispersing cuprous oxide in polymer ink；Equally, the structure
It can be set to porous structure, handled for photocatalysis sewage；
The uniformly dispersing fibre first in polymeric matrix film makes fiber become reticular structure, meanwhile, cuprous oxide is pre-
It is first supported on fiber, not only increases film strength in this way, cuprous oxide dispersion can also be made more uniform, it is sub- to improve oxidation
The utilization rate of copper.
A kind of photocatalysis water treatment structure is wanted including polymer frame and being supported on frame using any of the above-described right
Seek the composite membrane.
Preferably, the polymer frame is tridimensional network.
The photocatalysis water treatment structure can be used as carrier, composite membrane is supported in the photocatalysis treatment structure, specifically
, used tridimensional network can be improved the treatment effeciency of unit volume, to improve whole treatment effeciency.
Compared with prior art, beneficial effect is the utility model：It can be handled under light illumination with light-catalysed effect dirty
Water, and there is higher treatment effeciency.
