Description
Technical field
The present invention relates to a kind of photocatalysis pollution of river thing decomposition apparatus, belong to sewage disposal technology neck in environmental protection
Domain.
Background technology
Traditional method for treating water efficiency is low, high cost, there are secondary pollution problems, and waste water control always cannot be well
Solution.The development and application of nanometer technology are likely to thoroughly solve this problem., A.Fujishima and K.Honda in 1972
In n-type semiconductor TiO2The photoelectrocatalysis decomposition of water, TiO are found that on electrode2Oxidation activity is higher, and chemical stability is good,
Harmless to the human body, low cost is pollution-free, has a wide range of application, thus is most paid attention to, and is that current most widely used nanometer light is urged
Change material, be also the environmental type catalyst for most developing future.
Research shows, nano-TiO2Various toxic compounds can be processed, can be by the hydro carbons in water, halogenated hydrocarbons, acid, surface
Soon complete oxidation is CO for activating agent, dyestuff, itrogenous organic substance, organophosphorus insecticide, timber preservative and fuel oil etc.2、
H2The innocuous substances such as O.But up to the present nano-photo catalytic TiO2Technology is not used widely in terms of wastewater treatment yet, main
If because nano particle separates difficulty, without simply applicable processing equipment.
Loaded in carrier surface by nano particle, can solve the problems, such as that particle is separated.But it is loaded with nano particle
When carrier is soaked in water, the solution that exciting light must be transmitted through thicker (often more than several centimeters) can just be irradiated to catalysis
In agent.And in fact, either in ultraviolet region or visible region, organic solution (especially colored organic wastewater) is all
Different degrees of light absorbs are had, this will certainly cause the different degrees of light loss of exciting light, so as to get up to catalyst surface
Luminous intensity declines, so that the yield in light induced electron and hole declines, the final degradation efficiency for causing pollutant is reduced.
Patent CN 102515303A disclose a kind of device for photocatalytic abatement of organic pollution of riverway, can obtain preferably
Water treatment efficiency, but need the flowing of electric power and water.Equally, several patents such as CN104609571B, CN104609572B are disclosed
Method be all that the flowing for needing river can just obtain photocatalysis effect.If the fluid ability of river is not enough to pushing meanss
Rotate, then treatment facility may be made to fail.
The content of the invention
The purpose of the present invention is to solve the shortcomings of the prior art, a kind of photocatalysis pollution of river thing decomposition apparatus are proposed,
The device is simple, non-power consumption, only utilizes sun light action, you can reach preferable treatment effect.
The invention discloses a kind of photocatalysis pollution of river thing decomposition apparatus, including:
Horizontal frame, it is fixed on more than the water surface;
Fibrous braid, it is covered in the horizontal frame surface, and the fibrous braid side from horizontal frame
Edge hangs down, and is in contact with the water surface;Opposite side corresponding thereto hangs down from horizontal pane edge, near the water surface without contact water
Face;The fibrous braid surface is also loaded the catalyst with visible light activity;
Convex lens, it supports the top for being fixed on horizontal frame by support;The convex lens are by two of radial symmetric
Divide and constitute, described two parts are rotationally linked by hinge and are integrated.
In preferred technical scheme, the two ends of described convex lens are provided with temperature sensing spring, the two of the described convex lens of control
Part is rotated by axle center of hinge;When temperature sensing spring expanded by heating, two parts of convex lens are integrally formed, it is combined into complete
Convex lens.
The beneficial effects of the invention are as follows:Using the capillarity of fibrous braid, water is connect from fibrous braid and water
Tactile one end capillary is drunk up, and korneforos is instilled from the other end, and relatively thin liquid film is formed on fibrous braid surface, without any dynamic
Power can form a thin film system for constant flow, so as to obtain more preferable catalytic effect, and need not pass through additional means
Separating catalyst.
The convex lens of top can be with optically focused, and when the morning sun rises, temperature is relatively low, sun oblique fire, and now convex
The half of lens can just to the sun, and as the sun continues to rise, temperature is raised, and temperature sensing spring pushes convex lens two parts to water
Flat, large area receives to shine upon and focus the light into catalyst surface, improves catalytic efficiency.
Experiment is proved:For the concentration of II containing gold orange in the waste water of 25mg/L, the gold after 12h is persistently processed by the equipment
The clearance of orange II is up to 97.2%.
Brief description of the drawings
Fig. 1 is structural representation of the invention
Specific embodiment
Reference picture, an including horizontal frame 1 is fixed on more than the water surface, and the surface of horizontal frame 1 is coated with fibrous braid
2, the sagging contact water surface in the one end of fibrous braid 2, the other end it is sagging close to the water surface without contact the water surface, the surface of fibrous braid 2
It is loaded with the catalyst-silver phosphate with visible light activity.
One convex lens 3 is radially divided into symmetrical two parts by its center of circle, and two parts of convex lens 3 pass through side hinge
4 links are integrated, but can be with hinge 4 as axis rotation;Rotation of the two parts of convex lens 3 with hinge 4 as axle center is by two ends
It is individually fixed in the two-part temperature sensing spring 5 of convex lens 3 to control, when temperature sensing spring 5 is heated, then expands, can be by convex lens
Two parts are combined into complete convex lens;Two parts of convex lens 3 support 6 tops for being fixed on horizontal frame 1 by support.Operation
When device is fixed on river course surface, organic matter degradation in urban river water can be completed under the irradiation of sunshine.
