Description

Take precautions against the ultraviolet catalytic wastewater degradation reactor expansion method of secondary pollution

Technical field

The present invention relates to a kind of ultraviolet catalytic wastewater degradation reactor expansion method taking precautions against secondary pollution, belong to CO2F waste water Processing technology field.

Background technology

Microwave and photo catalysis degradation treatment technology, as a kind of effectively for the harmless treatment skill containing organic pollutants industrial wastewater Art, interesting in recent years.

With regard to microwave and photo catalysis degradation technique, as a case, may refer to the Chinese patent Shen of Publication No. CN102260003A Please case.

The Chinese patent application case that the disclosure number is CN102260003A, is using microwave as excitaton source, excites electrodeless ultraviolet lamp Launching ultraviolet, irradiating 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, the air being overflowed by quartz cavity 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 that retaining of photochemical catalyst titanium dioxide fine particles is used again；The program also non-polar ultraviolet light source and membrane separation assemblies it Between set up dividing plate, for preventing the radiation injury to organic membrane separation assemblies for the ultraviolet；It is passed through the air of inside reactor, Part 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 also plays the direct oxidative degradation for organic pollution certainly Effect.

The Chinese patent application case that the disclosure number is 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.

Based on the meaning of 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 Chinese patent application case that the disclosure number is CN102260003A, 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 rely 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 recovery, the recycling of catalyst particles 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 touching organic film assembly, this organic film assembly material in also requiring that device can be resisted Ultraviolet light irradiation, from the point of view of this, based on the organization plan of 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；With regard to this point, special for filtering technique It for the personage of industry, is known, here do not 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 solving, 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, With regard to 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 occupation mode, from the point of view of 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 too weak, so that cannot tackle the filter membrane of more small-bore at all, and thus, in this case device, filter sizes limits It between 0.1 micron-0.2 micron, 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, it is less than 100 The catalyst particles of nanometer by being directed through, by the filter opening of membrane module, be mixed into the 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 with the photochemical degradating reaction of uv light induction, 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 of these different preparation methods formation, 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, Without the level of production commercially available on a large scale can be formed；Known at present 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 using 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 here launch to repeat；The average grain diameter of gas phase titanium dioxide P25 is 21 nanometers；Gas Phase titanic oxide P25 performance does not includes optimum, but, its stable performance, it is important to can commercially make a big purchase in large quantities and obtain, and Can use in a large number at industrial scale, therefore, also 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 higher photochemical catalyst of decentralization, 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, ready-made commercially available business that is good and cheap, that can actual make a big purchase in large quantities, use 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, cleaning force that bubble washes away too weak, so that 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 Equal particle diameter is 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 using the titanium dioxide optical catalyst of the big particle diameter special for this of other kinds, it collides because of mutual during using Or with wall collision, 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, that the disclosure number is CN102260003A Chinese patent application case, it is for the interception structure of photochemical catalyst particulate The cleaning solution of scheme and related film assembly is all undesirable.

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

The three of problem:

It is known that liquid water body itself also can absorb the energy of microwave, and cause the liquid water body that is processed itself Temperature-rise effect, and this temperature-rise effect occurring with wastewater treatment process, be not but the situation that we are expected, in other words Saying, the microwave energy from magnetron is not used for exciting electrodeless ultraviolet lamp 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, with regard to this point, in this its detailed description of the invention of CN102260003A application case Clearly have expressed the suitable size overall with regard to this apparatus structure, its expressed preferred size is corresponding is exactly that a profile is very little Device, then, consequently, it is possible to the distance of reactor wall and microwave radiation source is little, the wastewater flow rate contacting with microwave is little, The microwave energy that waste water is absorbed is relatively also little, corresponds ground, and the wastewater treatment capacity of single tank is therefore also little, 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 carrying out the repetition being operated by a complete set of head to tail many times, the cumulative of its treating capacity just has plant-scale meaning, So to say, simply 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, so excessively 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 more microwave energy to waste or to reduce microwave energy waste, single tank wastewater treatment capacity is increased, Reduce this batch (-type) wastewater treatment equipment unnecessary too many and head to tail repeated number of times, improve its waste water and process effect Rate, is a significant technical problem meriting attention, and 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 slightly inadequate；Certainly, this weak point, for CN102260003A For clear the fact that express upper corresponding small size in scheme such as its detailed description of the invention, 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 not 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 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, following so several key element is had to influence whether that this kind of oxidation is anti- The efficiency answered, first ultraviolet wavelength, intensity, it two is the particle diameter of photochemical catalyst, photochemical catalyst in unit volume reactant liquor Usage amount, the photochemical catalyst catalytic performance of himself etc., it three is the concentration of organic matter 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 conditions In the case of identical, the sufficient degree of oxygen atmosphere, will become that to affect one of photochemical catalysis oxidative degradation ability act foot light 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 to be become 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 overflow cloth arrange mode, the supply of oxygen atmosphere excessively disperses, and actually 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, and therefore, the effective coverage needing most enhanced oxygen blowing to promote photochemical catalysis oxidation course is real 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 stronger, and oxidation reaction is also It just is proceeded more quickly；Especially 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 the little reactor that a single tank single treatment amount only has about 40 liters, in the case of such little reactor, little inner chamber, Because size is inherently very little, then, its shortcoming in terms of photochemical catalysis oxidation effective coverage oxygen supply concentration degree, would not So obvious, it might even be possible to ignore, a non-existent problem at all can be regarded more even 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 Use electrodeless ultraviolet lamp as the situation of UV source, oxygen supply strengthening in effective coverage within above-mentioned quartz ampoule periphery 20 cm distance 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, the usefulness improving 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:

This CN102260003A scheme pumps air into and includes within the quartz ampoule of electrodeless ultraviolet lamp, reaches 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 flowing 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 existing 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 Just very little, then, the longitudinal size of its reactor inner chamber or be regarded as with reckoning in every item contain the liquid degree of depth also can only be one very little Size, clearly illustrates among this size such as its detailed description of the invention, only about 40 centimetres, and the Sheng that reckons in every item liquid is deep Degree also just only 40 centimetres, actually contains the liquid degree of depth and is certainly less than this number, and just the Sheng liquid degree of depth with 40 centimetres is analyzed, that , this Sheng liquid degree of depth of 40 centimetres is what concept？That is to say, ascension containing ozone-air is by the path of waste water only Having short 40 centimetre, this path is too short, and bubble containing ozone-air passes through at a gallop only only has 40 centimetres of deep water bodys, The ozone too short, contained in bubble with water body time of contact, can only have small part to be used for oxidative degradation organic matter, And most ozone actually simply passes by liquid simply, effusion through exhaust port emptying 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 that 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 utilize completely 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 concern, it is clear that Ren Mengeng It is contemplated that ozone utilizes the reactor of wastewater degradation without extreme ultraviolet more complete, 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, can impartially, prematurely immediately stop to evening only 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, but still So 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 also undelayed instant information output in advance is made neither 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 wherein mingled with some 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 the dividing plate intercepting 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 the organic top layer of membrane separation assemblies 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, organic plasma membrane that it can be close to by nature divides Produce from the top layer of assembly and pierce destruction based on the lasting of heat penetration erosion mechanism, 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 heatproof temperature limit that the heat penetration erosion effect of formula very easily breaks through 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 significantly low In the preferable service life expected, the structure of this CN102260003A its device of application case, determine in this structural frames Under frame, the heat penetration erosion destruction problem that above-mentioned point-like pierces formula cannot be avoided；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 Chinese patent application case that the disclosure number is 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 causing；It when this catalyst particles is reunited, is immediately to adopt an effective measure, enters The depolymerization to aggregate for the hand-manipulating of needle operates；But, we, among this CN102260003A scheme, do not see any having Help the scheme prompting immediately dissolved the structure of this problem or can immediately dissolve this problem.For such as CN102260003A scheme can only be the reactor of small scale structures because factors limits just like that, still can manually directly carry React device, carries out toppling over and inspecting outside reactor, processes above-mentioned reunion situation, then, hold if being possible to expand it Amount, simply so to say, if being the several cubes of large-scale reactors to dozens of cube or huge reactor, that is obviously 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 Realizing 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 of processed industrial wastewater, unavoidably Gradually incrustation, the long-pending material of dirt is mainly difficult to the mineral-type impurity being touched by light-catalyzed reaction certainly, 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 Simply very 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 washes away the incrustation process that strength is still not enough to stop completely 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 also very important, and this is the ten of problem.

It is an advantage of the invention that the microwave constrainer by the caged of metal material, electrodeless ultraviolet lamp be wrapped among its inner chamber, And by its inner chamber of microwave constrainer of this caged and the waveguide UNICOM being derived from magnetron, microwave its entirety of constrainer of this caged Locations of structures is also in the inside of described quartz ampoule, and this quartz ampoule is the component being isolated, playing sequestering action for gas-liquid thing, By described step, the microwave coming via waveguide transmissions is constrained within its effective workspace, has contained microwave to periphery The unhelpful dissipation of waste water water body, and between microwave constrainer outer wall and reactor wall, build microwave weak irradiation spatial domain or microwave zero Irradiation spatial domain；This quartz ampoule and be placed into its lumen of megaphone-shaped component in state unsettled, vertical being positioned at reactor inner chamber Within upper area；The step of this case method also includes: microwave described in extension on three-dimensional, expansion inside reactor is weak Irradiation spatial domain or the size in microwave zero irradiation spatial domain, by this step, can significantly expand the design volume of reactor, it is allowed to anti- Answer device list tank wastewater treatment capacity to be substantially improved, and need not worry that microwave energy dissipates too much in unhelpful waste water water body temperature rise effect again Should.

In the case of using bright finished stainless steel wire cylinder mould as microwave constrainer, or, using punching corrosion resistant plate In the case of making microwave constrainer through mold pressing, welding or splicing process, via complicated mirror-reflection mechanism, can be with maximum limit Ultra-violet light transmission from electrodeless ultraviolet lamp is gone out by degree ground, and makes up himself entity of described metal cage to greatest extent to light Block, absorb caused loss.

Relying on this case method, the design volume of this wastewater degradation reactor is that single tank wastewater treatment capacity can be expanded to several cubes extremely Dozens of cube；Based on this case the method, a complete set, the frequency of omnidistance wastewater degradation operation can be greatly reduced, be conducive to The saving of human and material resources.

On the other hand, this case method makees the shuttling movement of relatively large yardstick with described megaphone-shaped component guided liquid-flow, in reactor The stream containing ozone bubbles of ascension can pull, guide the lumen rapid increase of the liquid flow of inside reactor along this megaphone-shaped component, And after in impact, by quartz ampoule peripheral light catalytic degradation reaction region, spread to surrounding by top area, via Zhou Bianqu Territory sinks, and reaches reactor intracavity bottom region, then through the stub end trunking down of this megaphone-shaped component to this loudspeaker Within the lumen of cylindrical member, continue its circulation；The liquid shuttling movement of this relatively large yardstick being guided, contributes to guaranteeing The homogenization of inside reactor liquid degradation reaction process, this, for large-scale degradation reaction device, is necessary.

UV source involved by this method of this case is to rely on microwave excited electrodeless ultraviolet lamp, and the ultraviolet radiation feature of this lamp-type is exactly can Accomplishing high-power, high intensity, but the Effective depth penetration that ultraviolet is in liquid water body only about 20 centimetres, therefore, Region within quartz ampoule periphery about 20 cm distance is effective coverage, and this region is exactly photochemical catalysis oxidative degradation Efficient region；This case device is with described megaphone-shaped component, and pack is from the bubble stream of numerous micro porous aeration heads so that it is Intensively towards the release of quartz ampoule peripheral light chemical catalytic oxidation effective coverage, this mode is favorably improved to be had described in quartz ampoule periphery The oxygen atmosphere supply intensity in effect region, helps speed up ultraviolet catalytic oxidation degradation reaction process.

Based on this method of this case, the capacity of reactor or treating capacity can significantly be expanded, and described significantly expand, and are by significantly expanding The design volume of microwave zero irradiation zone or the weak irradiation zone of microwave realizes, then, from the appearance, reactor horizontal Size, longitudinal size are all significantly to expand certainly, and therefore, inside reactor is contained the liquid degree of depth and can be added significantly similarly Deeply, for example, it is possible to deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., containing, liquid is deep In the case that degree is enough deep, containing ozone-air bubble ascension path long enough, steep, containing ozone-air, the time long enough contacting with water body, Just can with enough reducing substances fortune, and thoroughly or almost exhaust in bubble contained smelly up hill and dale during its ascension Oxygen, thus, in bubble containing ozone-air, ozone composition oxidation potential utilizes incomplete problem to be solved, and, Owing to long ascension path causes ozone depletion, reactor tail gas re-entrainment would not there is the ozone that can cause environmental pollution.

This method of this case with external multistage filter, reaches little from aggregate bulky grain to ten number nanometers to catalyst particles The interception step by step of the collision fragment of yardstick, recovery, reuse photochemical catalyst almost up hill and dale, take precautions against catalyst loss almost up hill and dale And the secondary pollution causing；This hold-up interception method secondary filter can be protected to make its filtration passage from bulky grain thing step by step 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 hold-up interception method, Can fully intercept nano level photochemical catalyst, it can intercept this average particle of gas phase titanium dioxide P25 certainly almost up hill and dale 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 hold-up interception method and catalyst The practical capacity of market supply, actual kind match, blend.

Further, involved by this method of this case catalyst intercept mechanism external, involved filter core need not be soaked in inside reactor Strong oxdiative, In the liquid of strong ultraviolet irradiation, therefore, it can to consider the tolerance to ultraviolet irradiation, Strong oxdiative condition completely, so, In the selection of filter core material just without extraordinary tolerance in terms of restriction, can carry out in more vast optional material species Select, and entirely without the material of the PVDF must being confined to again costly etc.

Involved by this method, filters at different levels are commercially available, commercially available filters at different levels, draining-off sewage when its sewage draining exit backwashes Floss hole, this case uses this kind of back flush type equipment, is used to intercept step by step catalyst particles, the sewage draining exit of originally commercially available equipment, It is used as being used delivery outlet again by the recycling delivery outlet retaining catalyst particles or backflow by conversion in the present case.

Already described above and, based on this case method, the capacity of reactor or treating capacity can significantly be expanded, and described significantly expand, and are 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 all significantly to expand certainly, 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, contain the liquid degree of depth enough deep in the case of, containing ozone-air bubble ascension path long enough, the bubble containing ozone-air contacts with water body Time long enough, just can be with enough reducing substances fortune during its ascension, and thoroughly or almost exhaust up hill and dale Ozone contained in bubble, thus, in bubble containing ozone-air, ozone composition oxidation potential utilizes incomplete problem to obtain 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 escapes liquid level；One of above speak of, the some problem that this case solves simultaneously, it 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 at its corresponding framework of this case method are stood to dozens of Under the process capacity framework of even hundreds of the cube volume in side, when inside reactor ullage has ozone effusion, i.e. show The degradation reaction of inside reactor has reached terminal, and be the overall uniformity of internal liquid reach the terminal of degradation reaction, this One terminal point determining factor is the matching criteria that can be provided by with this case scheme；This case fills in its exhaust port position of reactor If ozone sensor, ozone detected in this locations of structures, just mean that inside reactor degradation reaction is reached home, ozone Sensor and the composite structure connection with ozone attention device or ozone content display or ozone attention device and ozone content display Connect, for providing the information that indicates accurately, this case and the electric signal by ozone sensor output to be passed by cable to operating personnel Giving power-supply controller of electric, this power-supply controller of electric is simultaneously coupled with magnetron and air pump respectively by cable, and power-supply controller of electric is according to it Received described electric signal carries out power switch action, and certainly, its function mode is to receive ozone at power-supply controller of electric It when the signal of the ozone effusion that sensor sends, is automatically switched off the power supply leading to magnetron and air pump；This case method according to this, The terminal of inside reactor degradation reaction process can be known in time；And method according to this, it when reaction reaches terminal, 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 method according to this, when degradation reaction is reached home, the power supply of described magnetron and air pump can be closed 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；This case method determines the ozone that its corresponding framework do not has more than needed and is available for discharge.

Relying on this case method, the microwave irradiation spatial domain of inside reactor is by forcing to cut off, limiting, this case and use external level Join multistage backwash filter and carry out the fine interception for catalyst particles, among this method, back flush type doughnut micro-filtration Membrane module and back flush type polysulfone hollow fiber ultrafiltration membrane system are all by external and away from reactor core, and microwave can not be irradiated to institute completely Stating membrane module, based on this case the method, having got around described point-like completely and pierced the heat penetration erosion destruction problem of formula, this problem thus obtains To good solution.

This case simultaneously installs ultrasonic transducer at reactor bottom, based on this method, can at once start ultrasonic radiation work(when necessary Energy；Address above, some pH value be pre-adjusted not in place, pH value inappropriate in the case of, titanium dioxide fine particles is easily sent out Raw reunion, and then affect its effective working interface area, affect its photocatalysis usefulness；Particularly with that among this particle size range The section of a little relatively small particle diameters, easily occur especially because of pH value presetting not in place, pH value is incorrect and the agglomeration traits that causes； It when this catalyst particles is reunited, is immediately to adopt an effective measure, carry out the depolymerization running for aggregate； In the case of catalyst particles generation serious agglomeration, the ultrasonic transducer that this case method is arranged on reactor bottom can facilitate Ground OnNow, immediately implements depolymerization running, thus achieves at for the instant original position of this catalyst particles agglomeration traits Put.

Protect the quartz ampoule of electrodeless ultraviolet lamp, its outer wall in reactor for screen, refer to the outer wall of quartz ampoule, through for a long time with The contact of processed industrial wastewater, unavoidably gradually incrustation, the long-pending material of dirt is mainly difficult to be touched by light-catalyzed reaction certainly Mineral-type impurity, the incrustation phenomenon being formed because of this mechanism, it is easy to be observed after equipment long-play；It is attached to institute State the dirty lamination of quartz ampoule outer wall, although simply very thin one layer, also be enough to cause the ultraviolet radiation of electrodeless ultraviolet lamp significantly Stop, the actual treatment effect causing this microwave and photo catalysis reaction treating device is significantly reduced by this；This case method its reaction The ultrasonic transducer installed bottom device, in the irregular depolymerization being carried out for accidental catalyst particles serious agglomeration situation Among running, its ultrasonic wave being radiated, certainly also can reach quartz ampoule position, this ultrasonic wave is carrying out depolymerization fortune in situ While work, also carry out the ultrasonic clean scale removal work for the long-pending thing of quartz ampoule surface dirt in the lump；Further, ultrasonic transducer Installation site away from quartz ampoule position, ultrasonic radiation has decayed when reaching quartz ampoule position, therefore, quartz ampoule Ultrasonic impact suffered by surface is low intensive ultrasonic impact, this low intensive ultrasonic impact can leniently scale removal, It is avoided that again or significantly weakens its quartz ampoule surface smoothness loss being likely to result in of ultrasonic cavitation；Based on this case method, Can immediately, effectively remove the dirty lamination on this quartz ampoule outer wall, thereby safeguard that this microwave light is urged on the premise of not tearing machine open Change the lasting high efficiency of degradation reaction device.

In short, this case method allows reactor design capacity significantly to expand；Meanwhile, this method also enhances inside reactor liquid The shuttling movement of relatively large yardstick；This method solves simultaneously and utilizes incomplete containing ozone composition oxidation potential in ozone-air bubble Problem；This method and reached for nm-class catalyst particulate from its aggregate bulky grain to ten number nanometers collision fragments wide General, fine interception；The selection face also expanded because of this method of involved its material of filter core；Its degradation reaction endpoint information energy Enough known in time；The input of the energy to reactor can be automatically switched off when its degradation reaction terminal；Its degradation reaction terminal it When, also automatically terminate the generation process of ozone in time, it is to avoid unnecessary secondary pollution；The method simultaneously can immediately in situ Dispose accidental catalyst particles serious agglomeration situation, also simultaneously incidentally with the low-intensity after teletransmission appropriateness reduction Gentle supersonic cleaning described in quartz ampoule surface, keep the ultraviolet light transparent performance that it is excellent.
