Description
Technical field
The present invention relates to a kind of cooperated with light, sound and electricity effect the get off method and the device thereof of degradation of organic waste water, belong to photocatalysis technology and handle organic waste water and environmental engineering technical field based on nano-photocatalyst material.
Background technology
In recent years, photocatalysis oxidation technique has caused the extensive attention of materialogy, chemistry and Environmental Science and Engineering educational circles, has carried out a large amount of research.Facts have proved, utilize TiO
2The photohole of photocatalyst or active free radical can organic pollutant exhaustive oxidation some toxicity are big, difficult for biological degradation be H just under normal temperature, normal pressure
2O, CO
2Deng small molecules.Photocatalysis technology not only can be handled multiple organic pollutant, and has the effect of good sterilization and inhibition virus activity.That had studied is used for light-catalysed catalyzer, comprises TiO
2, ZnO, CdS, ZnS, AgI etc.Because TiO
2Catalytic activity height, chemical property are stable, cheap and safe in utilization, are a kind of ideal photocatalysts and being widely studied.
Yet also there are a lot of problems in the technology of photocatalytic degradation organic waste water.At first, mostly the catalyzer that uses is granular powder, though can obtain degradation effect preferably, nano level powder is suspended in the waste water after the processing, make follow-up catalyst separating become difficult, the difficulty of catalyst recovery also makes the powder photocatalysis technology be difficult to obtain practical application.In order to solve the difficulty of catalyst recovery, Chinese patent publication number CN 1565982A, CN 1415557A report adopts the fluidized-bed mode to make decomposition apparatus, but because the agglomeration of nanometer grade powder, its degradation rate is still not satisfactory.Secondly, TiO
2Catalyzer is after UV-irradiation, and the photohole of generation and light induced electron are very easy to be compound, makes that the utilization ratio of UV-light is on the low side.
In recent years, some new researchs improve the problem that photocatalysis technology exists.In order to solve the recovery difficult problem of powder catalyzer, the photocatalysis apparatus of development selection is recently filmed with sol-gel method or the powder adhesion thin film-forming method prepares immobilized catalyst film (CN 1563490A, CN 1562776A) on base material.The type curing catalysts can carry out the recycle of catalyzer effectively.Simultaneously, by the Preparation of Catalyst after immobilized is become optoelectronic pole, light-electric concerted catalysis technology is used.In light-electric concerted catalysis degraded, the electric field that applying bias imports can make that photohole and electronics are more efficiently to be separated, and improves the degradation effect of pollutent greatly.But new problem is following, owing to film or the catalyst film of bonding mode preparation and substrate bonded and insecure, under long voltage effect, catalyst film is easy to crack, come off, cause whole catalyzer to lose activity the most at last, decomposition apparatus loses effect.It is less with the catalytic film reaction area of bonding mode preparation to film simultaneously, and degradation effect is restricted.
Be coated with the membranous type photocatalyst easily under the electric field synergistic effect outside the inactivation, and the collaborative main ultraviolet excitation that relies on of light-electricity, handle colourity and turbidity than higher waste water in, usually be limited by the system transmittance, the feasible light intensity that can arrive catalyzer is lower, can't excite catalyzer effectively, cause whole system degradation efficiency low.Recent discovers, ultrasound wave irradiation is introduced also exciting light catalyzer effectively of whole system under no optical condition, and pollutent is degraded.Introduce the ultrasound wave irradiation low waste water of transmittance of can degrading effectively, but, be coated with the membranous type photocatalyst and easily come off from substrate because ultrasound wave irradiation can produce the effect of intensive mechanical shearing to catalyst film.So ultrasonically catalyzing still uses the powder catalyzer mostly, this just makes catalyst recycling face difficulty again again.In order to integrate the multipotency field effectively, to have given play to the collaborative efficient of multipotency field fully, break through photocatalytic degradation The Application of Technology difficulty, be badly in need of the catalysis technique that design makes new advances.

Ultimate principle of the present invention or mechanism and characteristics thereof:
Principle of the present invention is to utilize electric field separates photohole-electron pair, uses ultrasonic wave raising mass transfer effect and utilizes the better exciting light catalyzer of hyperacoustic cavitation effect.Experiment showed, any factor that slows down light induced electron and hole-recombination or help electron hole subtend adsorbent to shift, all will improve TiO
2Photocatalytic activity.And electronics can be flowed to negative electrode by external circuit under the photoelectrocatalysis condition of input anodic bias.So just greatly reduce the recombination rate of electron-hole pair, thereby greatly improved photo-quantum efficiency.So the photoelectrocatalysis reaction efficiency is obviously greater than simple light-catalyzed reaction efficient.
Under hyperacoustic irradiation, ultrasonic cavitation takes place in the aqueous solution, at the utmost point of cavitation bubble collapse in the short period of time, cavitation bubble and focus occurs in the little space scope on every side, generation is up to the high temperature of 1900-5000K and surpass the high pressure of 50662kPa, water vapour generation pyrolysis in the bubble produces OH and H.And the generation of OH free radical TiO just
2The principal element of photocatalyst generation redox reaction, thereby hyperacoustic synergy accelerated the process of redox reaction, thus improved DeR speed.Research is in the last few years also found, under the condition that no UV-light participates in, adds TiO in ultrasonic system
2Photocatalyst also can obtain to be similar to the effect of ultraviolet excitation photocatalyst.With reference to the dynamochemical result of study of sound, there are two kinds of catalyzer excitation mechanisms to accept substantially.1) sonoluminescence mechanism.This mechanism can make this experimental fact of plate sensitization in the water prove by ultrasonic wave.Ultrasound wave irradiation can inspire UV-light (wavelength is about 360nm) in the aqueous solution, this UV-light can be used for exciting TiO
2Powder is brought into play the effect of its photocatalyst.2) high thermal excitation mechanism." focus " that ultrasonic wave produces in water itself just can make water molecules produce the extremely strong OH free radical of oxidisability, but efficient is lower up to several thousand K.Heterogeneous TiO
2Catalyzer obtains to cause behind this part energy Sauerstoffatom to flee from lattice and produce the hole, and the existence in hole can cause the OH free radical equally and generate.Ultrasonic wave can improve mass-transfer efficiency simultaneously, makes that the degradation effect of whole system is better.Electric field and ultrasonic wave is effective in the purpose that finally reaches the degraded organic wastewater with difficult degradation thereby.
In order to make good use of the synergistic effect of light, electricity, sound, the immobilized mode that solves catalyzer is an a great problem.At first, must make catalyzer be convenient to recycling; Secondly, make the catalyzer film forming and make conductive capability good light electrode; At last, catalyst film is combined firmly with substrate, be able to take the high-energy ultrasound wave irradiation and do not peel off or come off.
Technical solution key of the present invention is to utilize anodizing technology to prepare nano-TiO
2Pipe array film material, and with as the high optoelectronic pole of catalytic activity.Because TiO
2Firm in the metal Ti substrate, make that adding bias voltage becomes possibility.And because its outstanding adhesive ability, can not make also under hyperacoustic situation that catalyst film comes off from substrate adding, make the repeated use of nano-photocatalyst become possibility, powder catalyst separating recovery problem is also avoided.Increase access times, reduced cost.Simultaneously, because this film is pipe battle array material, the specific surface area of this kind material is bigger, can obtain more reflecting point, obtains better effect.
