Detailed description of the invention
Principle and the spirit of the present invention are described below with reference to some illustrative embodiments.Should manage
Solve, be given these embodiments be only used to make those skilled in the art better understood when and then
Realize the present invention, and limit the scope of the present invention the most by any way.On the contrary, it is provided that these are implemented
Mode is to make the disclosure more thorough and complete, and can the scope of the present disclosure intactly be passed
Reach to those skilled in the art.
Fig. 1 shows the schematic diagram of the water treatment system according to an embodiment of the invention.
As it is shown in figure 1, this system includes: seal case 1, in described seal case 1, arrange
Have: what at least one had a water inlet 2 and a delivery port 3 has nano photocatalyst catalytic material
Pipelined channel 4, described water inlet 2 and delivery port 3, penetrate the left side of described seal case 1 respectively
(certainly, in other embodiments, water inlet 2 and delivery port 3 can also be positioned at seal box with right side
The same side of body 1)；At least one radiating light source 6, is positioned at the outside of described pipelined channel 4, uses
In irradiating described pipelined channel.
Wherein the effect of seal case 1 is protection water treatment system, and prevents radiating light source from escaping to outward
Boundary's environment.Seal case 1 can be the metal cabinet of such as iron, opaque plastic box body, plank,
Cement partition wall or the mixture of above-mentioned four kinds of casings.Radiating light source for example, 380 nano wave length
UV light source.
Described pipelined channel 4 at least partly has the inner tubal wall 5a being coated with nano photocatalyst catalytic material, or
Person, is placed with at least one dividing plate 5b being coated with nano photocatalyst catalytic material in described pipelined channel 4.
The present invention does not has the concrete where being limited to pipelined channel 4 and has and be coated with nano photo-catalytic
The inner tubal wall 5a of material, and where is placed with at least one dividing plate being coated with nano photocatalyst catalytic material
5b, as long as radiating light source 6 can be irradiated to have the inner tubal wall 5a being coated with nano photocatalyst catalytic material
Or the dividing plate 5b being coated with nano photocatalyst catalytic material is the most permissible.The quantity of light source, size, can depend on
Actual demand is adjusted.Volume that dividing plate is shared in pipelined channel and dividing plate institute in pipelined channel
The parameter adjustments such as water resistance, water purification amount, partition shape can be considered in position.
Described nano photocatalyst catalytic material can be TiO2, ZnO, SnO2, ZrO2, CdS, ZnS,
Or other absorbable radiating light source radiation light and cause photochemistry or the material of light-catalyzed reaction or this
The combination of a little materials.In the following description, as a example by TiO2, but when actually used, and
It is not only restricted to only use this material.
Under the irradiation of radiating light source, the photochemical reaction of photocatalyst material can be activated, and with contact
Environment, i.e. water, react, produce free radical, these free radicals will further with in environment
Bacterial action, and destroy the structure of bacterium, thus reach to kill the purpose of bacterium.
Illustrate as a example by TiO2 is under the radiation of ultraviolet below:
Under the ultraviolet irradiation (radiation) containing wave band A, the Electron absorption on TiO2 surface is enough
Energy and depart from, and just form the electric hole of positively charged in the position of electron detachment, electricity hole can be by neighbouring water
Molecule dissociates the hydroxy (OH-) oxidation (i.e. capturing its electronics) so that it is become activity greatly
Hydroxyl free radical (OH radical), hydroxyl free radical once meets organic matter (bacterium), just
Can be recaptured by electronics, now, bacterium can be dead because of being destroyed of the molecular binding of self, and releases
Release electronics then can react with O2, formation oxygen free radical O2-, this O2-free radical also can with carefully
Bacterium effect, thus destroy the integrality of bacterial structure.
Many studies demonstrate that photocatalyst material under nanoscale, its light-catalyzed reaction can obtain into one
Step ground promotes.Table one be Escherichia coli (E.Coli) on different base materials, through the purple of different time
After outside line is irradiated, then after 24 hour cells are cultivated, Escherichia coli survival situation.
Table 1
| Illumination 30 seconds | Illumination 45 seconds | |
| The glass of the irradiation of light without UV is from base material test piece | The most | The most |
| Glass baseplate test piece through UV light irradiation | A lot | A lot |
| The thin TiO2 film test piece of glass substrate surface only a layer through UV light irradiation | A little | Seldom |
| Through the glass substrate surface of UV light irradiation, there is the film test piece of nano-scale structure TiO2 | No | No |
As shown in Table 1, relative to there is no the test piece of irradiation ultraviolet radiation, after ultraviolet is illuminated, greatly
The survival rate of enterobacteria reduces, and this represents, using the most merely ultraviolet sterilization is to have certain effect
Fruit.The result of table 1 also show, the existence of TiO2 film, can add the sterilization of intensive ultraviolet
Ability.Further, when employing the TiO2 with nano-scale structure, it appeared that examination
On sheet, the not Bacillus coli cells of remaining.This result represents, uses and has nano-scale structure
TiO2, has the effect of good disinfection.
The method making the pipelined channel with nano photocatalyst catalytic material has three kinds:
The first, utilize transparent material, such as: glass, plastic cement (PC, PI, PET) etc., logical
