Abstract

The present invention discloses a kind of capillarity auxiliary pollution of river thing catalytic degradation device, it is characterized in that including：One horizontal frame, it is fixed on more than the water surface；Fibrous braid, is covered in the horizontal frame surface, and a line of the fibrous braid hangs down from horizontal frame edge, contacts the water surface, and another a line corresponding thereto also hangs down from horizontal pane edge, close to the water surface without the contact water surface；The fibrous braid surface is also loaded the catalyst with visible light activity.A thin film system for constant flow can be formed without any power, so as to obtain more preferable catalytic effect, and additional means separating catalyst need not be passed through.

Description

A kind of capillarity aids in pollution of river thing catalytic degradation device
Technical field
The present invention relates to a kind of capillarity auxiliary pollution of river thing catalytic degradation device, belong in environmental protection at sewage Reason 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 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, propose a kind of capillarity auxiliary pollution of river thing catalysis Decomposition apparatus, the device is simple, non-power consumption, only utilizes sun light action, you can reach preferable treatment effect.
A kind of capillarity auxiliary pollution of river thing catalytic degradation device disclosed by the invention, including：
One horizontal frame, it is fixed on more than the water surface；
Fibrous braid, is covered in the horizontal frame surface, and the fibrous braid a line from horizontal frame Edge hangs down, and contacts the water surface, and another a line corresponding thereto also hangs down from horizontal pane edge, close to the water surface without contact water Face；
The fibrous braid surface is also loaded the catalyst with visible light activity.
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.
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 95%.
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 with visible light activity.Device is fixed on river course surface during operation, under the irradiation of sunshine Complete organic matter degradation in urban river water.
