Technical field

The present invention relates to a kind of Large-capacity ultraviolet photocatalytic waste water degradation device having concurrently and taking precautions against secondary pollution function, belong to CO2F Technical field of waste water processing.

Background technology

Microwave and photo catalysis degradation treatment technology, as a kind of effective for the harmless treatment skill containing organic pollution industrial wastewater Art, the most interesting.

About microwave and photo catalysis degradation technique, as an example, may refer to the Chinese patent Shen of Publication No. CN102260003A Please case.

The disclosure number is the Chinese patent application case of CN102260003A, is using microwave as excitaton source, excites electrodeless ultraviolet lamp Launching ultraviolet, irradiate the suspension mixed with photochemical catalyst titanium dioxide in liquid internal, this electrodeless ultraviolet lamp is by quartz ampoule institute cage Cover protects, and is free air pump persistently to inject air to this quartz ampoule inner chamber, quartz cavity the air overflowed via pipeline be positioned at anti- Answering the micro porous aeration head UNICOM bottom device, the lower zone of this inside reactor is aeration zone, the upper area of this inside reactor Being microwave and photo catalysis reaction zone, the program also with the membrane separation assemblies that reactor is built-in, carries the water after analysis purifies, and with this film Separation assembly realizes retaining of photochemical catalyst titanium dioxide fine particles and uses；The program also non-polar ultraviolet light source and membrane separation assemblies it Between set up dividing plate, for preventing the ultraviolet radiation injury to organic membrane separation assemblies；It is passed through the air of inside reactor, Part the most directly participates in relying on the photocatalytic degradation of photochemical catalyst titanium dioxide to react, some air, direct at ultraviolet light Under irradiation, generating a certain amount of ozone, the ozone of this generation the most also plays the direct oxidative degradation for organic pollution Effect.

The disclosure number is that the Chinese patent application case of CN102260003A is certainly for microwave and photo catalysis wastewater degradation technology Progress serves very important impetus, and the work that its research staff is launched in this field is admirable.

Meaning based on sincere admiration, and, common striving direction, to be talked below us is problem.

The problem below will spoken of, has ten；This ten problems is ten problems arranged side by side；The priority of its sequence is only Consider easily for discussing.

One of problem:

The disclosure number is the Chinese patent application case of CN102260003A, and it divides for the film intercepting catalyst titanium dioxide fine particles It is to be placed in reactor inner chamber from assembly, is immersed among process object liquid, and relies on washing away containing ozone bubbles of ascension Membrane separation assemblies, the institute's catalyst particles that adsorbs, be detained that thereby removes its surface, reach the recovery of catalyst particles, recycling Purpose, meanwhile, it is self-cleaning and keep its separating power that membrane separation assemblies is also dependent on this mode, then, based on this structure, only Business curtain hollow fiber film assembly or plate film assembly can be selected, and, this membrane separation assemblies is to need to be immersed in ozone In the context of the strong oxidizing property of bubble ascension, therefore, the tolerance against oxidative power of membrane separation assemblies is necessarily required, common material The organic film separation assembly of matter is not resistant to such use environment, therefore can only select the membrane separation assemblies of PVDF material, this Point clearly illustrates in the 0009th section of word of this case disclosure and claim 3；This kind needs special tolerance against oxidative power Its material of filter membrane is relatively costly, and its commercially available price is certainly also above common organic micro-filtration membrane module of non-oxidation durability requirements；Change Sentence is talked about, and the frame mode of this case causes the material of membrane separation assemblies to be limited to PVDF material costly.Further, dress Putting interior possible ultraviolet light to reveal, may touch organic film assembly, this organic film assembly material also required that in device can be resisted Ultraviolet light irradiation, from the point of view of this, organization plan based on this device, the material of organic film separation assembly also can only be limited in PVDF material costly.

Organic film assembly, compared to ceramic filter assemblies, has its obvious advantage；About this point, special for filtering technique For the personage of industry, it is known, does not the most launch to repeat.

So, under the premise using organic material membrane module, this PVDF filter membrane material limitation can be bypassed？This is One needs the problem solved, and this is one of problem.

The two of problem:

In view of scouring force, the cleaning capacity of described ascension bubble are more weak, therefore, with this cleaning mode with the use of UF membrane The filter opening aperture of bigger micro-filtration rank can only be selected in its aperture of assembly, and the filter opening aperture of this micro-filtration rank is 0.1-0.2 micron, About this point, have in the 0009th section of word of this case disclosure and claim 3 equally and clearly limit, this kind of filter opening aperture Limit, from the type selecting of the such membrane separation assemblies of this case, built-in and soak from the point of view of occupation mode, the self-cleaning method of ascension bubble, be Inevitable, its filter opening aperture can only be limited in micro-filtration rank.In other words, this in the way of ascension bubble washes away its scouring force, Cleaning force is the most weak, to such an extent as to cannot tackle the filter membrane of more small-bore at all, and thus, in this case device, filter sizes limits Between 0.1 micron-0.2 micron, it it is the inevitable choice not discussing leeway.

The filter opening aperture of so-called 0.1-0.2 micron, if changing a measurement unit, corresponding is exactly the filter opening hole of 100-200 nanometer Footpath；That is any concept？For 100 nanometer filter opening apertures of its lower limit, its size of catalyst particles that it can intercept Must be more than 100 nanometers, and cannot be intercepted less than the catalyst particles of 100 nanometers；In other words, less than 100 The catalyst particles of nanometer by being directed through, by the filter opening of membrane module, be mixed into so-called water purification that degradation reaction device exported it In.

Need now to have a talk the particle diameter of photochemical catalyst involved by ultraviolet catalytic degradation reaction and photochemical catalyst dosage form selection.

The professional person being engaged in photocatalytic degradation research both knows about, and reacts with the photochemical degradating of uv light induction, and its catalyst is many Select titanium dioxide fine particles catalyst；At present, laboratory level has been developed for various in style urging based on titanium-dioxide photo Changing the light degradation particle catalyst of characteristic, certainly, the light degradation catalyst that these different preparation methods are formed, its particle diameter is also It is various；Its particle diameter of photochemical catalyst that different preparation methods are made is little to 20 nanometers, greatly to 100000 nanometers namely 100 microns, Have, be wherein no lack of the photochemical catalyst kind of excellent performance；But, due to performance long-time stability evaluate, preparation cost and The restriction of market expansion etc. aspect factor, most of its deliverability of described photochemical catalyst is limited only to laboratory level, And do not have to form the most commercially available level of production；The most known can make a big purchase in large quantities commercially available can be actual a large amount of The photochemical catalyst for ultraviolet light wave band used is famous gas phase titanium dioxide P25；Its concrete skill of gas phase titanium dioxide P25 Art implication, insider both knows about, and does not the most launch to repeat；The average grain diameter of gas phase titanium dioxide P25 is 21 nanometers；Gas Phase titanic oxide P25 performance not very optimum, but, its stable performance, it is important to can commercially make a big purchase in large quantities and obtain, and Can use the most in a large number, therefore, the most usually be used as weighing respectively with P25 catalyst in photocatalysis specialized laboratory Plant reference pointer or the contrast pointer of self-made photocatalyst catalytic performance, it is true that in view of the feature of ultraviolet catalytic degradation reaction, The photochemical catalyst that decentralization is the highest, is suitable for the needs of this type reaction, say, that average grain diameter is at the light of 21 ran Catalyst its catalyst interfacial area that can provide, anti-settling ability, catalytic performance long-time stability etc. aspect, comprehensive and Speech, is optimal.Simply, at present, good and cheap, it is possible to the actual ready-made commercially available business making a big purchase in large quantities, using The photochemical catalyst of the ultraviolet light wave band of grade, it is simply that average grain diameter is the gas phase titanium dioxide P25 catalyst of 21 nanometers；In industry The application of scale, this average grain diameter be the photochemical catalyst of 21 nanometers be actual first-selection.

Already described above and, the disclosure number is the Chinese patent application case of CN102260003A, and it is for intercepting the film of photochemical catalyst Assembly, is the catalyst particles that stripping film assembly surface adsorbs, deposits that washes away with ascension bubble, but, this kind is to rise Rise its scouring force of mode that bubble washes away, cleaning force the most weak, to such an extent as to the filter membrane of more small-bore cannot be tackled at all, therefore, In this case device, filter sizes is limited at micro-filtration filter opening rank between 0.1 micron-0.2 micron, for changing a measurement unit, In this case device, filter sizes is limited at the micro-filtration filter opening rank between 100 nanometer-200 nanometers, and this is not discuss leeway Inevitable choice；This case certainly cannot intercept as above flat without the micro-filtration filter opening between selectable 100 nanometer-200 nanometers All particle diameters are the gas phase titanium dioxide P25 particle of 21 nanometers；So, if using P25 photochemical catalyst, this catalyst will completely Cannot intercept, and flow in so-called water purification, form secondary pollution, certainly also result in the heavy losses of catalyst and unrenewable； Even if using the titanium dioxide optical catalyst of the big particle diameter special for this of other kind, it collides because of mutual during using Or collide with wall, inevitable also can produce a large amount of small particle fragment, wherein particle diameter is less than the fragment of 100 nanometers, equally can not be by Micro-filtration filter opening between 100 nanometer-200 nanometers is intercepted, these fractionlets also can through its membrane module enter so-called water purification it In, form secondary pollution.

Visible, the disclosure number is the Chinese patent application case of CN102260003A, and it is for the interception structure of photochemical catalyst particulate The cleaning solution of scheme and related film assembly is the most undesirable.

Therefore, how under the premise of this case advantage of incorporating things of diverse nature, reach the fine interception for photochemical catalyst particulate and return Receiving use again, be a important topic the most worth thinking deeply about, this is the two of problem.

The three of problem:

It is known that liquid water body itself also is able to absorb the energy of microwave, and cause the liquid water body that is processed itself Temperature-rise effect, and this with wastewater treatment process the temperature-rise effect that occurs, be not the most our situation of being expected, in other words Saying, the microwave energy from magnetron is used for exciting electrodeless ultraviolet lamp the most completely, and has quite a few should be served only for swashing The microwave energy sending out electrodeless ultraviolet lamp is dissipated in described temperature-rise effect, and it is unnecessary that the temperature-rise effect that this kind is not fond of causes Microwave energy waste, in view of disclosed above number be CN102260003A the apparatus structure side that shown of Chinese patent application case Case, its rational approach, can only be to reduce single tank process capacity in other words by the volume of minimizing microwave and photo catalysis reactor to come Reach the purpose weakening the unnecessary dissipation of microwave, about this point, in this its detailed description of the invention of CN102260003A application case Clearly have expressed the suitable size overall about this apparatus structure, what its expressed preferred size was corresponding is exactly that a profile is the least Device, then, consequently, it is possible to the distance of reactor wall and microwave radiation source is little, the wastewater flow rate contacted with microwave is little, The microwave energy that waste water is absorbed is the least, corresponds ground, and the wastewater treatment capacity of single tank is the least, more specifically Ground is said, the internal capacity corresponding to device suitable size expressed in embodiment is 40 liters, namely single tank wastewater treatment capacity is 40 liters, i.e. 0.04 cube, in other words, its once a complete set of, substantial length of operation solve only the industrial wastewater of 0.04 cube, then, Being accomplished by the repetition operated by a complete set of head to tail carried out many times, the cumulative of its treating capacity just has plant-scale meaning, So to say, the most individual analogy substantially, 0.04 cube of such waste water of single tank that its preferred structure size of this case is generally corresponding to Treating capacity, need to repeat 1000 times by a complete set of head to tail, substantial length of operation, its accumulation amount, can be only achieved 40 cubes such one Individual have industrial level wastewater treatment capacity, the most loaded down with trivial details repeating will cause the serious waste of human and material resources, Visible, the wastewater degradation treatment effeciency of its reality of scheme that this kind is shown by CN102260003A may not be fully up to expectations. Therefore, how on the premise of not causing the waste of more microwave energy or reducing microwave energy waste, increase single tank wastewater treatment capacity, Reduce this batch (-type) wastewater treatment equipment unnecessary too many and repeated number of times by head to tail, improve its waste water and process effect Rate, is a significant technical problem merited attention.

On the other hand, according to the literature, some system, in the case of microwave direct irradiation wastewater liquid, photochemical catalysis is dropped Solve efficiency and truly have raising, say, that in some system, between microwave direct irradiation wastewater liquid and photochemical catalysis degraded, There is certain coupling.

Therefore, how on the premise of taking into account described coupling, improve the treatment effeciency of wastewater degradation device, be worth inquiring into, This is the three of problem.

The four of problem:

The scheme that this kind is shown by CN102260003A, the bubble of the internal unrestrained cloth ascension of its retort, for driving a reaction tank The shuttling movement of the relatively large yardstick of internal liquid, contributes the most inadequate；Certainly, this weak point, for CN102260003A In scheme such as its detailed description of the invention the fact that clear expression for upper corresponding small size, low capacity device, almost without what Observable impact.From the point of view of plant-scale application demand, undersized can not the device of divergence process amount certainly the most much Attraction；So, as a kind of possibility, if there being certain mode to be capable of the significantly expansion for the treatment of capacity, under this situation, Its importance of shuttling movement of the relatively large yardstick of retort internal liquid will highlight naturally；Imagine the most this process The possibility that amount is significantly expanded, then, how to strengthen the shuttling movement of the relatively large yardstick of retort internal liquid, be certainly exactly Individual problem, this is the four of problem.

The five of problem:

For the photochemical catalysis oxidation reaction of ultraviolet light wave band, this kind of oxidation is anti-to have the most several following key element to influence whether The efficiency answered, first ultraviolet wavelength, intensity, it two is photochemical catalyst in the particle diameter of photochemical catalyst, unit volume reactant liquor Usage amount, himself catalytic performance etc. of photochemical catalyst, it three is organic concentration in oxidized object i.e. water body, has Oxidation complexity that machine thing molecular structure is determined himself etc., it four is the sufficient degree of oxygen atmosphere, in other condition In the case of identical, the sufficient degree of oxygen atmosphere, will become and affect an act foot of photochemical catalysis oxidative degradation ability gently The key element of weight.

The scheme shown such as CN102260003A, its numerous micro porous aeration heads being placed in reactor inner chamber bottom overflow cloth the end of at Portion, and by its alleged water distributing plate so that this micro porous aeration head overflows the effect of cloth arrangement and becomes more very, certainly, this for For using the situation of oarse-grained micron-sized photochemical catalyst of relatively easy sedimentation, really there is its favourable one side, but, From the point of view of another side, this micro porous aeration head overflows the mode that cloth arranges, and the supply of oxygen atmosphere excessively disperses, and needs most The region that need to strengthen oxygen supply is the most effective region of photochemical catalysis oxidation, due to effective in liquid water body of short wave ultraviolet Penetration depth only has 20 cm, therefore, needs most enhanced oxygen blowing real with the effective coverage promoting photochemical catalysis oxidation course It is exactly the region within quartz ampoule periphery about 20 cm distance on border, in other words, within quartz ampoule periphery about 20 cm distance Region be the region really needing the supply of enriched with oxygen atmosphere to ensure, oxygen atmosphere supply in this region is the strongest, and oxidation reaction is also Just it is proceeded more quickly；The most especially, producing electrodeless ultraviolet emission in microwave excitation mode, its feature can be accomplished greatly exactly Power, high intensity, this is the strong point of this lamp-type of electrodeless ultraviolet lamp, but, just because of its purple extraradial high power, high-strength Degree, just mates with greater need for powerful oxygen atmosphere supply capacity, and otherwise, that powerful ultraviolet radiation energy power is just Really major part is wasted.Above it is stated that, the scheme shown such as CN102260003A, factors limits Its reactor size, limits its actual treatment capacity, as its specific embodiment clearly illustrates, that Can be a single tank single treatment amount little reactor that only has about 40 liters, in the case of such little reactor, little inner chamber, Because size is the least, then, its shortcoming in terms of photochemical catalysis oxidation effective coverage oxygen supply concentration degree, would not The most obvious, it might even be possible to ignore, a problem the most non-existent can be regarded the most completely as, in the face of such Undersized little reactor, the shortcoming problem in terms of oxygen supply concentration degree, not may float mind；However, it is contemplated that Once, if described many limiting factors can be overcome, if can have that way actual implementation one is large-scale, high throughput anti- Answer device, then within above-mentioned quartz ampoule periphery 20 cm distance, effective coverage oxygen supply strengthening problem will show especially out, particularly with Using electrodeless ultraviolet lamp as the situation of UV source, within above-mentioned quartz ampoule periphery 20 cm distance, effective coverage oxygen supply is strengthened Problem is not more allowed to despise, therefore, how among the structure of possible large-scale photo-catalytical oxidation degradation reaction device, Strengthen the oxygen supply concentration degree of described effective coverage, improve the usefulness of wastewater degradation equipment, it is simply that the problem that individual needs are kept a close watch on, this is The five of problem.

The six of problem:

Within this CN102260003A scheme pumps air into the quartz ampoule including electrodeless ultraviolet lamp, reach the logical of electrodeless ultraviolet lamp Wind cooling, the purpose of cooling, and those flowings are through the air of quartz ampoule, because of by ultraviolet irradiation, some air meeting Being changed into ozone, therefore, the air flowed out from quartz ampoule is exactly the air containing some ozone certainly, and the program should It is transferred to be positioned at micro porous aeration head below reactor containing ozone-air, and disengages from micro porous aeration head, at these containing ozone bubbles certainly Lower and on ascension during, ozone contained therein can meet with the organic molecule that runs among distance and occur redox anti- Should, this redox reaction can consume a part of ozone certainly, this be do not have doubt, but, above it is stated that, as The scheme that CN102260003A is shown, the many factors that cannot ignore certainly existed limit its reactor size, Limiting its actual treatment capacity, as clearly illustrating in its specific embodiment, that can only be a single tank single Treating capacity only has the little reactor of about 40 liters, in the case of such little reactor, little inner chamber, because overall dimension itself The least, then, the longitudinal size of its reactor inner chamber or regard as with reckoning in every item contain the liquid degree of depth also can only be one the least Size, clearly illustrates among this size such as its detailed description of the invention, the most about 40 centimetres, and the Sheng that reckons in every item liquid is deep Spend the most only 40 centimetres, actually contain the liquid degree of depth and be certainly less than this number, just analyze with the Sheng liquid degree of depth of 40 centimetres, that , this Sheng liquid degree of depth of 40 centimetres is what concept？That is to say, containing ozone-air ascension by the path of waste water only Having short 40 centimetre, this path is the shortest, passes through at a gallop containing ozone-air bubble and only only has 40 centimetres of deep water bodys, The shortest for time of contact with water body, contained in bubble ozone, can only have small part to be used for oxidative degradation organic matter, And most ozone actually simply passes by liquid simply, effusion emptying through exhaust port from liquid level, briefly, The oxidation potentiality major part of these ozone is wasted, and, effusion, the ozone that is wasted actually can cause need not The air pollution wanted；This case main inventive people once beat via micro porous aeration head with normal domestic use ozone machine in one meter of deep tank Enter containing ozone-air, in the case of the depth of water degree of depth reaches one meter, remain able to substantially smell the smell of ozone near the water surface, can See, that 40 centimetres of deep Sheng liquid degree of depth, it is clear that be to be not enough to fully utilized ozone；Visible, electrodeless ultraviolet light chemistry is urged For changing the such equipment of wastewater degradation reactor, ozone utilizes incomplete problem to be also required to pay close attention to, it is clear that Ren Mengeng It is contemplated that the reactor of wastewater degradation without extreme ultraviolet that ozone utilizes more completely, contaminative exhaust emissions is less, this is the six of problem.

The seven of problem:

Its running of waste water catalytic degradation reaction device, requires the expenditure of energy, and therefore, operating personnel are bound to wish, work as wastewater degradation When reaction proceeds to terminal, it is possible to impartially, the most lately immediately stop continuing to inject to inside reactor Energy；If the moment stopping Implantation Energy is too early, then wastewater degradation is incomplete；And if reaching reaction end already, the most still The most unceasingly to inside reactor Implantation Energy, that is certainly the energy in waste preciousness.As this case technical background Its structure of CN102260003A scheme can not provide any instant information to the wastewater degradation reaction end moment, then, just The terminal that wastewater degradation reacts can only be estimated by experience；And estimate, by experience, the terminal that wastewater degradation reacts, that obviously can not Satisfactory；So, how to make neither the most undelayed instant information output for the wastewater degradation reaction end moment, And immediately close the input of the energy to reactor in the just right moment, it is simply that a technical threshold that can not despise, this is The seven of problem.

The eight of problem:

Accept the described industrial wastewater of microwave and photo catalysis degradation treatment, be mingled with some the most unavoidably and originate from mechanical system abrasion process The material of metal particle and carbon granules etc, even if quantity is small, its existence is almost difficult to avoid that, the disclosure number is Described organic membrane separation assemblies in the Chinese patent application case of CN102260003A is installed in microwave and photo catalysis reaction zone, its In be installed between quartz ampoule and membrane separation assemblies certainly do not stop microwave for intercepting the dividing plate of ultraviolet, so, micro- The practical function region of ripple necessarily covers organic membrane separation assemblies institute installation area described in the program, based on membrane separation assemblies Working mechanism, its accumulation process on membrane separation assemblies organic matter top layer of the particulate of metal particle as above and carbon granules etc It is difficult to avoid that, and the particulate of this type of described metal particle and carbon granules etc, exactly the good absorption medium of microwave energy, inhale The particulate of described metal particle and the carbon granules of having received the accumulation state of microwave energy etc, its organic plasma membrane being close to can be divided by nature Produce from the top layer of assembly and based on heat penetration erosion mechanism lasting pierce destruction, be as noted previously, as this CN102260003A The structures shape of its device of application case can only select polyvinylidene fluoride film material, this polyvinylidene fluoride film material heatproof about 140 degrees Celsius, More certain than general film material heatproof high much, but, described metal particle and carbon granules of absorbing the accumulation state of microwave energy etc Its point-like of particulate pierce the heat penetration erosion effect of formula and the most easily break through the heatproof temperature limit of this polyvinylidene fluoride film material, due to above-mentioned former Cause, well imagines, the pvdf membrane material in this its device of CN102260003A application case its actual life will be the lowest In the preferable service life expected, the structure of this CN102260003A its device of application case, determine in this structural frames Under frame, above-mentioned point-like pierce formula heat penetration erosion destruction problem cannot avoid；Therefore, how to get around this point-like and pierce the heat penetration erosion of formula Destruction problem, also needs to consider, and this is the eight of problem.

The nine of problem:

The disclosure number is the Chinese patent application case of CN102260003A, the 0008th section of word of its specification disclosure text And claim Section 2, the catalyst particle size scope being suitable for for its device, there is a restriction, this particle size range limits It is that 20 nanometers are to 100 microns.It is known that some pH value be pre-adjusted not in place, pH value inappropriate in the case of, Titanium dioxide fine particles is susceptible to reunite, and then affects its effective working interface area, affects its photocatalysis usefulness；Particularly with The section of those the relatively small particle diameters among this particle size range, easily occurs because of presetting not in place, the pH value of pH value not especially The agglomeration traits appropriately caused；For this catalyst particles in the case of of reuniting, it is immediately to adopt an effective measure, enters The depolymerization of aggregate is operated by the hand-manipulating of needle；But, we, among this CN102260003A scheme, do not see any having Help immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem.For such as CN102260003A scheme can only be the reactor of small scale structures because factors limits just like that, still can the most directly carry React device, carries out toppling over and inspecting outside reactor, process above-mentioned reunion situation, then, hold if likely expanding it Amount, the most so to say, if being the several cubes of large-scale reactors to dozens of cube or huge reactor, that is the most not It is manual to topple over it and operate the problem that can tackle, then, for this catalyst particles in the case of of mutually reuniting, how Realize instant disposal in situ, it is simply that a technical problem, this is the nine of problem.

The ten of problem:

The disclosure number be CN102260003A Chinese patent application case expressed by apparatus structure in, protect electrodeless purple for screen The quartz ampoule of outer lamp, its outer wall, refer to the outer wall of quartz ampoule, through for a long time with the contacting, unavoidably of processed industrial wastewater Gradually incrustation, the material that dirt amasss the most mainly is difficult to the mineral-type impurity touched by light-catalyzed reaction, because of the formation of this mechanism Incrustation phenomenon, is easy to be observed after equipment long-play；It is attached to the dirty lamination of described quartz ampoule outer wall, although The veryyest thin one layer, also be enough to cause the ultraviolet radiation of electrodeless ultraviolet lamp significantly stop, and this will cause this microwave light to be urged The actual treatment effect changing reaction treating device significantly reduces；In its reactor, the bubble of unrestrained cloth ascension is because excessively disperseing, scouring force Measuring more weak, if only relying on this more scattered bubble to maintain the bright and clean of quartz ampoule surface, really undertaking to do what is apparently beyond one's ability, in other words Saying, this more scattered bubble, what it was more weak wash away strength is still not enough to stop completely the incrustation process on this quartz ampoule surface；? During the use of laboratory yardstick, above-mentioned fouling problem is subtle, but, on commercial Application yardstick, this fouling problem Certainly will highlight；Therefore, how on the premise of not tearing machine open, immediately, effectively remove on this quartz ampoule outer wall Dirt lamination, maintains the lasting high efficiency of this microwave and photo catalysis processing means, and this problem is the most very important, and this is the ten of problem.

Based on this case structure, the most single tank wastewater treatment capacity of the design volume of device can be expanded to several cubes to dozens of cube； The volume of hundreds of cubes of even single tank, is also to allow；Based on this structure of this case, a complete set, whole process can be greatly reduced The frequency of operation, the beneficially saving of human and material resources.

This case, on the premise of taking into account described microwave excitation auxiliary, has been reached photocatalytic waste water degradation reactor design capacity and has significantly been expanded The target opened.

This case device its run among, its high density ascension bubble stream discharged of described cluster-shaped micro porous aeration head cluster, Upwards while ascension, and wrapped folder, carry, guided liquid-flow, form a kind of motion being similar to fountain form, this kind motion In, be derived from the high density bubble stream wrapped folder of described cluster-shaped micro porous aeration head cluster liquid gush to metal cage region and On, and then the more intensively impact inside and outside close position of metal cage, existed by described high density bubble stream wrapped folder, the liquid flow carried Impact, by the inside and outside close position of metal cage after, by the liquid layer of top area to surrounding spread, via neighboring area sink, Arrive reactor intracavity bottom region, then its high density ascension bubble stream discharged through described cluster-shaped micro porous aeration head cluster Wrapped folder, carrying, continue its motion being similar to fountain form, so circulation is endlessly；The liquid of this relatively large yardstick guided Body shuttling movement, contributes to guaranteeing the homogenization of inside reactor liquid degradation reaction process, and this urges for large-scale electrodeless ultraviolet light For changing degradation reaction device, it is necessary.

Its UV source of this case structure is to rely on microwave excited electrodeless ultraviolet lamp, and the ultraviolet radiation feature of this lamp-type is exactly permissible Accomplish high-power, high intensity, but the Effective depth penetration that ultraviolet is in liquid water body only has 20 cm, therefore, Region within quartz ampoule periphery about 20 cm distance is the effective coverage of photochemical catalysis oxidative degradation, and this region is same Time be also that microwave excitation promotes and the efficient region of photochemical catalysis oxidative degradation coupling；This effective coverage Partly or entirely it is coated with by the metal cage of also printing opacity permeable, ventilative；This case method is to be positioned at the described cluster immediately below metal cage Shape micro porous aeration head cluster, intensively discharges highdensity ascension bubble stream so that it is as fountain intensively towards as described in effectively Region discharges, and the method is favorably improved the oxygen atmosphere supply intensity of described effective coverage, helps speed up degradation reaction process.

Can significantly expand based on this case structure, the capacity of reactor or treating capacity, described significantly expand, be by significantly expanding The design volume of microwave zero irradiation zone or the weak irradiation zone of microwave realizes, then, the lateral dimension of reactor, longitudinal ruler Very little is all significantly to expand certainly, and therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, such as, and can To deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., containing the feelings that the liquid degree of depth is the deepest Under condition, containing ozone-air bubble ascension path long enough, steep the time long enough contacted with water body, its ascension process containing ozone-air In just can be with abundant reducing substances fortune, and thoroughly or be close to and exhaust ozone contained in bubble up hill and dale, thus, Incomplete problem is utilized to be solved containing ozone composition oxidation potential in ozone-air bubble, and, due to long Ascension path cause ozone depletion, reactor tail gas re-entrainment would not have the ozone that can cause environmental pollution.

This case structure is with external multistage filter, reaches little from aggregate bulky grain to ten number nanometer to catalyst particles The interception step by step of the collision fragment of yardstick, is close to recovery, reuse photochemical catalyst up hill and dale, is close to and takes precautions against catalyst loss up hill and dale And the secondary pollution caused；This intercepts scheme step by step and secondary filter can be protected to make its filtration passage from bulky grain thing The rigid obstruction of matter；Wherein the pre-filtering aperture of the first order is between 5 microns and 300 microns, and its aperture of the micro-filtration of the second level exists Between 25 nanometers and 1000 nanometers, its aperture of the ultrafiltration of the third level is between 15 nanometers and 2 nanometers；Such interception scheme, Can fully intercept nano level photochemical catalyst, it can be close to interception gas phase this average particle of titanium dioxide P25 up hill and dale certainly Footpath is the catalyst of 21 nanometers；Address above, the gas phase titanium deoxide catalyst of nano level P25 etc, be can be a large amount of The commercially available catalyst buied, is also durability, stability, the known excellent photochemical catalyst of ultraviolet light wave band photocatalysis performance, Certainly, it is also the photochemical catalyst in fact paying the utmost attention in industrial scale applications select；This case catalyst intercepts scheme and catalyst The practical capacity of market supply, actual kind match, blend.

Further, in this case, it is external mechanism that catalyst intercepts mechanism, and based on this structure, its filter core need not be soaked in reactor The Strong oxdiative in portion, strong ultraviolet irradiation liquid in, therefore, it can need not to consider completely to ultraviolet irradiation, Strong oxdiative condition resistance to Stress, so, just without the restriction in terms of extraordinary tolerance in the selection of filter core material, can selection more vast Select in matter kind, and entirely without the material of the PVDF must being confined to again costly etc.

Involved filters at different levels are commercially available, commercially available filters at different levels, the discharge of draining-off sewage when its sewage draining exit is exactly to backwash Mouthful, this case uses this kind of back flush type equipment, is used to intercept step by step catalyst particles, the sewage draining exit of the most commercially available relevant device, The recycling delivery outlet or backflow that are used as by retaining catalyst particles by conversion in the present case use delivery outlet again.

Already described above and, can significantly expand based on this case structure, the capacity of reactor or treating capacity, described significantly expand, be Realized by the design volume significantly expanding microwave zero irradiation zone or the weak irradiation zone of microwave, then, from the appearance, The lateral dimension of reactor, longitudinal size are the most all significantly to expand, and therefore, inside reactor contains the liquid degree of depth similarly Can deepen significantly, for example, it is possible to deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc. Deng, in the case of the Sheng liquid degree of depth is enough deep, containing ozone-air bubble ascension path long enough, the bubble containing ozone-air contacts with water body Time long enough, just can be with abundant reducing substances fortune during its ascension, and thoroughly or be close to and exhaust up hill and dale Ozone contained in bubble, thus, utilizes incomplete problem to obtain containing ozone composition oxidation potential in ozone-air bubble Thoroughly solve, and, owing to long ascension path causes ozone depletion, reactor tail gas re-entrainment would not have and can cause The ozone of environmental pollution；Only when being subject to processing reducing substances in water body i.e. organic pollution is degraded totally, in water body Through again without being available for the organic pollution of ozone oxidation reaction, those unnecessary ozone it is possible to no longer consume and pass through long Ascension path effusion liquid level；Having spoken of, among the some problem that this case solves simultaneously, is enhanced reactor The circulation of the relatively large yardstick of internal liquid, the systemic circulation mechanism that this enhances facilitates the organic dirt contained by it of inside reactor liquid The uniformity of dye thing degradation reaction process, thus, several cubes allowed in this case structure the most hundreds of to dozens of cube Under the process capacity framework of individual cube volume, when inside reactor ullage has ozone effusion, i.e. show inside reactor Degradation reaction reached terminal, and be internal liquid entirety uniformity reach the terminal of degradation reaction, this terminal point determining Factor is the matching criteria that can be provided by with this case organization plan；Ozone is installed in this case in its exhaust port position of reactor Sensor, detects ozone in this locations of structures, just means that inside reactor degradation reaction is reached home, ozone sensor And couple with the composite structure of ozone content display with ozone attention device or ozone content display or ozone attention device, be used for The information that indicates accurately, this case and the electric signal by ozone sensor output is provided to send power supply to by cable to operating personnel Controller, this power-supply controller of electric is also coupled with magnetron and air pump respectively by cable, and power-supply controller of electric is according to received by it Described electric signal carry out power switch action, certainly, its function mode is, receives ozone sensor at power-supply controller of electric and sends out When the signal of the ozone effusion sent, it is automatically switched off and leads to magnetron and the power supply of air pump；This case organization plan according to this, can and The terminal of Shi Zhixiao inside reactor degradation reaction process；And organization plan according to this, when reaction reaches terminal, it is automatically switched off magnetic Keyholed back plate and the power supply of air pump, stop to inside reactor Implantation Energy in time, so can avoid unnecessary energy waste；And And, this case structure according to this, when degradation reaction is reached home, it is possible to close described magnetron and the power supply of air pump in time, This power-off action also synchronizes, the same generation process terminating in a flash ozone, owing to ozone generation process is terminated in time, The a large amount of ozone that would not have more than needs disengage from described exhaust port, thus avoid unnecessary secondary pollution or say secondary Raw pollution；Its framework of this case determines the ozone that it does not have more than needed and is available for discharge.

Among this case structure, the microwave irradiation spatial domain of its inside reactor is cut off by forcing, limits, this case and use external Cascading multiple stages backwash filter structure intercepts catalyst particles, back flush type hollow fiber microfiltration membrane assembly therein subtly And back flush type polysulfone hollow fiber ultrafiltration membrane system is the most external and away from reactor core, microwave can not be irradiated to described film group completely Part, based on this structure of this case, has got around described point-like completely and has pierced the heat penetration erosion destruction problem of formula, and this problem thus obtains well Solution.

This case structure is installed in the ultrasonic transducer of reactor bottom, it is possible to the most at once start；Address above, Some pH value be pre-adjusted not in place, pH value inappropriate in the case of, titanium dioxide fine particles is susceptible to reunite, and then impact Its effective working interface area, affects its photocatalysis usefulness；Particularly with the relatively small particle diameter of those among this particle size range Section, easily occur especially because of pH value presetting not in place, pH value is incorrect and the agglomeration traits that causes；For this catalyst The situation of particle agglomeration, is immediately to adopt an effective measure, and carries out operating for the depolymerization of aggregate；At catalyst particles When there is serious agglomeration, this case structure is positioned at reactor bottom ultrasonic transducer can OnNow easily, Immediately implement depolymerization running, thus achieve and dispose in situ for the instant of this catalyst particles agglomeration traits.

Structure is protected for screen the quartz ampoule of electrodeless ultraviolet lamp, its outer wall, refers to the outer wall of quartz ampoule, through long and quilt Processing the contact of industrial wastewater, the most gradually incrustation, the material that dirt amasss the most mainly is difficult to the nothing touched by light-catalyzed reaction Machine class impurity, the incrustation phenomenon formed because of this mechanism, it is easy to be observed after equipment long-play；It is attached to described The dirty lamination of quartz ampoule outer wall, although the veryyest thin one layer, also be enough to cause the ultraviolet radiation of electrodeless ultraviolet lamp significantly Stopping, the actual treatment effect causing this microwave and photo catalysis reaction treating device is significantly reduced by this；This case structure is positioned at reaction Ultrasonic transducer bottom device, in the irregular depolymerization running carried out for accidental catalyst particles serious agglomeration situation Among, its ultrasonic wave radiated, the most also can arrive quartz ampoule place locations of structures, this ultrasonic wave is carrying out depolymerization fortune in situ While work, carry out amassing for quartz ampoule surface dirt the ultrasonic clean scale removal work of thing the most in the lump；Further, ultrasonic transducer Installation position away from quartz ampoule place locations of structures, ultrasonic radiation has decayed when arriving quartz ampoule position, therefore, stone Ultrasonic impact suffered by English tube-surface is low intensive ultrasonic impact, and this low intensive ultrasonic impact can leniently remove Dirt, is avoided that again or significantly weakens its quartz ampoule surface smoothness loss being likely to result in of ultrasonic cavitation；Should based on this case Structure, it is possible on the premise of not tearing machine open, removes the dirty lamination on this quartz ampoule outer wall immediately, effectively, thereby safeguards that this is micro- The lasting high efficiency of glistening light of waves catalytic degradation reaction device.

In short, this case utilizes metal cage to retrain microwave more closely, reach and allowed reactor design capacity significantly to expand Target；Meanwhile, its scheme also enhances the shuttling movement of relatively large yardstick of inside reactor liquid；The program to be set up in Its highdensity bubble stream discharged of described cluster-shaped micro porous aeration head cluster immediately below metal cage, it is achieved degrade for emphasis Being substantially improved of the oxygen supply concentration degree of reaction zone；The program and having reached for nm-class catalyst particulate from big of its aggregate Grain to ten number nanometers collision fragments widely, fine interception；Based on this organization plan, the selection face of its filter core material is also Thus expanded；Its degradation reaction endpoint information can be known in time；It is right to be automatically switched off when its degradation reaction terminal The energy input of reactor；When its degradation reaction terminal, terminate the generation process of ozone the most in time, it is to avoid need not The secondary pollution wanted；Its structure also can dispose accidental catalyst particles serious agglomeration situation the most in situ, the most incidentally Quartz ampoule surface described in the supersonic cleaning of the low intensive gentleness after weakening through teletransmission appropriateness, keeps it excellent Ultraviolet light transparent performance.

This case solves described series of problems totally.
