Description
Technical field
This utility model belongs to application field of water treatment, refers in particular to a kind of waste water based on thin layer moisture film ultraviolet catalytic waste water and processes dress
Put.
Background technology
Photocatalysis waste water technology belongs to water-treatment technology field.This technology have novelty, high efficiency, to waste water non-selectivity etc.
Advantage, is particularly suitable for the degraded of unsaturated hydrocarbon, and reaction condition is the gentleest, non-secondary pollution, has well application
Prospect.Its operation principle is when there is semiconductor powder catalyst in organic wastewater, after the ultraviolet light of some strength irradiates,
System just can produce a certain amount of, the reactive oxygen species and free radicals of various ways, owing to these reactive oxygen species and free radicals have higher
Oxidizing potential, so can and Organic substance effect make it degrade, and then mineralising is water and carbon dioxide, thus reaches to administer
Purpose.
The type of sewage-treating reactor mainly has: a class is to utilize nature light (sunlight) to be radiation source, use catalyst
The flat-plate reactor of immobilization technology；Another kind of is to utilize artificial light source (uviol lamp) to be radiation source, use fine catalyst
Suspension photo catalysis reactor.
Photocatalytic reactor and shortcoming thereof are as follows at present:
(1) flat photo catalysis reactor
Flat photo catalysis reactor is direct part and the scattered portion taking full advantage of sunlight, makes the utilization rate of luminous energy significantly
Improve.Under some region and certain condition, the too scattered portion of the ultraviolet component in eye is even above direct part, because
Steam not Ultraviolet radiation absorbing, so no matter this reactor is at fine day or cloudy day, has goodish treatment effect.Flat board
Formula photo catalysis reactor has higher sunlight utilization rate, simple in construction, it is not necessary to sunlight tracking system, is suitable for different
Weather conditions, to material without particular/special requirement.But hydraulic load is relatively low, it is difficult to apply to the process of big flow sewage.
(2) tubular type photo catalysis reactor
This is a kind of reactor that type is most, and shape is all cylinder, and catalyst has two kinds of existence forms, and one is fixed bed
Formula, will TiO2It is carried on the carriers such as silica gel, bead, sandstone, glass fibre, is then filled in pipe or directly will
Catalyst is carried on tube wall；Its two be slurry formula, i.e. catalyst with suspension exist with in pipe.But it is suitable only for laboratory
Research, and it is suitable only for the research of suspended state liquid phase light-catalyzed reaction, there is no wide variety of prospect.
(3) chemical fibre photo catalysis reactor
It can regard the further improvement of fixed bed photocatalytic reactor as, be a kind of design exclusively for light-catalyzed reaction anti-
Answer device.Titanium dioxide in chemical fibre formula reactor is supported on optical fibers outer layer by suitable method, and ultraviolet light is from optical fiber
One end imports, and in optical fiber, refraction occurs thus irradiates titanium dioxide layer and make catalyst stimulation, and it is that optical fibers is as to solid phase
The medium of titanium dioxide transmission luminous energy.But fibre bundle and auxiliary equipment thereof are costly, it are difficult to spread and use.
(4) fludized bed photoreactor
Fluidized-bed reactor can solve catalyst and reactant liquor contact problems well, because the catalysis of support type photo catalysis reactor
The raising of efficiency is the most mainly the most fully determined by the size of specific surface area of catalyst and illumination, and fluidized-bed layer carrier is not
Cutout is moved, migrates, is rolled, reactant liquor constantly between carrier granular flowing can make full use of catalyst surface, be effectively improved
Catalyst effective ratio area.But there is catalyst and reclaim the problems such as difficult.
Above is that generally speaking, these reactors are according to catalyst about being above some basic conditions about reactor
Existence can be basically divided into fixed and slurry formula two kinds.In outstanding slurry reactor, typically directly by catalyst granules with
Pending waste water mixes, and makes catalyst be uniformly dispersed by stirring, owing to specific surface area of catalyst is big, has Organic substance preferably
Adsorption and have preferably absorption to photon, therefore degradation efficiency is higher.But also exist catalyst be difficult to efficient recovery,
Aqueous solution easily occur cohesion make the defects such as active ingredient loss, it is difficult to apply in reality.
For the deficiency of slurry photocatalytic reactor, the most fixed photo catalysis reactor is developed rapidly.So-called solid
Fixed pattern photo catalysis reactor will be fixed on carrier or make thin film process waste water by catalyst, is not required to extras and just can make catalyst
Recycling.
General uviol lamp mounting means uses " immersion " and " overflow-type ", and this installation side not only can not make full use of
Ultraviolet light, and higher to the prescription of uviol lamp, have impact on the effect of reaction.
This utility model overcomes the shortcoming that catalyst is directly mixed by outstanding slurry reactor with waste water, but also improves uviol lamp peace
The shortcoming being placed in waste water, uses and is placed on reaction zone by uviol lamp, react the moisture film from nozzle, not only improve
The life-span of uviol lamp, it is simple to change, more improve the speed of reaction.
