Abstract
The invention discloses a device for degrading pollutants by coordinating a capillary effect with photocatalysis. The device comprises an inclined plate and a fiber braided fabric, wherein the inclined plate is fixed above the water surface; an included angle between the inclined plane and the horizontal plane is 10 degrees to 30 degrees; the fiber braided fabric covers one end, far away from the water surface, of the inclined plane; one edge of the fiber braided fabric droops from the edge of the inclined plane and is in contact with the water surface; a catalyst with visual light activity is further loaded on the surface of the inclined plane. A thin film system capable of continuously flowing can be formed without any power so that a better catalysis effect is obtained; the catalyst can be separated without the need of an additional way.
Description
Technical field
The present invention relates to a kind of capillarity cooperative photocatalysis degradation of contaminant device, belongs to sewage disposal in environmental conservation
Technical field.
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 nanotechnology is likely to thoroughly solve this difficult problem.1972, A.Fujishima and K.Honda
In n-type semiconductor TiO2The photoelectrocatalysiss 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, applied range, thus is most paid attention to, and is that current most widely used nanometer light is urged
Change material, and 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 used widely in terms of wastewater treatment not yet, main
If because nano-particle separates difficult, the not simple processing equipment being suitable for.
Loaded in carrier surface by nano-particle, the detached problem of granule can be solved.But it is loaded with nano-particle
When carrier is soaked in water, exciting light must be transmitted through the solution of thicker (often more than several centimeters) and 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
Light 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 discloses a kind of device for photocatalytic abatement of organic pollution of riverway, it is possible to 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
Present invention aims to the deficiencies in the prior art, propose a kind of capillarity cooperative photocatalysis pollution degradation
Thing device, the device are simple, non-power consumption, only utilize sun light action, you can reach preferable treatment effect.
A kind of capillarity cooperative photocatalysis degradation of contaminant device disclosed by the invention, including：
One swash plate, which is fixed on more than the water surface, and the swash plate is 10~30 ° with horizontal plane angle；
Fibrous braid, is covered in the one end of the swash plate away from the water surface, and a line of the fibrous braid is from oblique
Under edges of boards marginal lappet, the water surface is contacted；
The swash plate surface is also loaded the catalyst with visible light activity.
The invention has the beneficial effects as follows：Using the capillarity of fibrous braid, water is connect from fibrous braid and water
Tactile one end capillary drinks up, and in swash plate surface wettability, forms very thin liquid layer, and under the irradiation of sunlight, pollutant are obtained
Photocatalyst for degrading effect.
The thin film system of a constant flow can be formed without the need for any power, so as to obtain more preferable catalytic effect, and
And additional means separating catalyst need not be passed through.
Test is proved：For the concentration of II containing gold orange is in the waste water of 25mg/L, the gold after the equipment persistently processes 24h
The clearance of orange II is up to 92.5%.
Description of the drawings
Fig. 1 is the structural representation of the present invention
Specific embodiment
Reference picture, a swash plate 1, which is fixed on more than the water surface, and the swash plate 1 is 10~30 ° with horizontal plane angle；Fiber
Fabric 2, is covered in the one end of the swash plate 1 away from the water surface, and a line of the fibrous braid 2 is hung down from swash plate edge
Under, contact the water surface；1 surface of the swash plate is also loaded the catalyst-silver phosphate 3 with visible light activity.
Device is fixed on into river course surface during operation, with capillarity, liquid film is formed in catalyst surface, in sunlight
Irradiation under can complete organic matter degradation in urban river water.
