Description
Technical field
The utility model relates to a kind of modified form photocatalytic reaction device that is used for water treatment, belongs to technical field of sewage in the environment protection.
Background technology
Traditional water treatment method efficient is low, cost is high, have secondary pollution problems, the solution that waste water control can not get always.The development of nanotechnology and application thoroughly solve this difficult problem probably.1972, A.Fujishima and K.Honda were at n N-type semiconductorN TiO
2Found the photoelectrocatalysis Decomposition of water on the electrode, TiO
2Oxidation activity is higher, and chemicalstability is good, and to the human non-toxic evil, cost is low, and is pollution-free, applied range, thereby paid attention to most, be present most widely used nano-photocatalyst material, also be the environmental type catalyzer that has the exploitation future most.
Research shows, nano-TiO
2Can handle multiple toxic compounds, can with the hydro carbons in the water, halohydrocarbon, acid, tensio-active agent, dyestuff, itrogenous organic substance, organic phosphorous insecticide, wood preservative and fuel wet goods soon complete oxidation be CO
2, H
2Innoxious substances such as O.But nano-photo catalytic TiO up to the present
2Technology is not used widely aspect wastewater treatment yet, mainly is because the nano particle separation difficulty does not have the simple treatment facility that is suitable for.
In the carrier surface load, can solve the problem of particle separation through nano particle.But when load had the carrier of nano particle to be soaked in the water, the solution that exciting light must see through thicker (often more than several centimetres) just can shine on the catalyzer.And in fact; No matter be at ultraviolet region or visible region; Organic solution (especially with the look organic wastewater) all can have photoabsorption in various degree, and this will certainly cause exciting light light loss in various degree, makes the light intensity that arrives catalyst surface descend; Thereby make the productive rate in light induced electron and hole descend, finally make the degradation efficiency of pollutent reduce.Patent CN100509639C discloses a kind of ramp type photo electrocatalysis reactor, can obtain the light-catalyzed reaction of water thin film promotion preferably, but lamp places the swash plate outside, has the loss of light.Equally, CN101774661A, CN102030387A, CN101993129A several patents disclosed method all is the side that excitation light source is positioned over the catalyst cupport plate, has the loss of luminous energy.In order to improve degradation efficiency, can only improve the power of excitation light source, so just increased operation energy consumption.
