Description

Vehicle reclaims the photochemical catalysis wastewater degradation reactor expansion method that link promotes
Technical field
The present invention relates to a kind of vehicle and reclaim the photochemical catalysis wastewater degradation reactor expansion method that link promotes, belong to the C02F technical field of waste water processing.
Background technology
Microwave and photo catalysis degradation treatment technology, effectively for the innoxious process for treating that contains the organic pollutant trade effluent, quite concerned in recent years as a kind of.
About the microwave and photo catalysis degradation technique, as an example, can referring to publication number, be the Chinese patent application case of CN102260003A.
The disclosure number is the Chinese patent application case of CN102260003A, to using microwave as excitaton source, excite electrodeless ultraviolet lamp emission ultraviolet ray, in liquid internal, irradiate the suspension that is mixed with photocatalyst titanium dioxide, this electrodeless ultraviolet lamp is shrouded and is protecting by silica tube, there is pneumatic pump to continue to inject air to this silica tube inner chamber, the air overflowed by quartz cavity is via pipeline and the micro porous aeration head UNICOM that is positioned at reactor bottom, the lower zone of this inside reactor is aeration zone, the upper area of this inside reactor is the microwave and photo catalysis reaction zone, this scheme is also with the built-in membrane separation assemblies of reactor, carry the water of analysing after purification, and realize that with this membrane separation assemblies holding back again of photocatalyst titanium dioxide fine particles use, this scheme is also set up dividing plate between non-polar ultraviolet light source and membrane separation assemblies, be used to preventing the radiation injury of ultraviolet ray to organic membrane separation assemblies, pass into the air of inside reactor, part is participated in the photocatalytic degradation reaction that relies on photocatalyst titanium dioxide directly, some air, under the direct irradiation of UV-light, generate a certain amount of ozone, the ozone of this generation is also being brought into play the direct oxidative degradation for organic pollutant certainly.
The disclosure is number for the Chinese patent application case of CN102260003A has certainly played very important pushing effect for the progress of microwave and photo catalysis wastewater degradation technology, and the work that its research staff launches in this field is admirable.
Based on the meaning of sincere admiration, and, common striving direction, what below us, will talk is problem.
The problem that below will speak of, have 15; These 15 problems are 15 problems arranged side by side; The priority of its sequence is only to consider for discussing easily.
One of problem:
The disclosure number is the Chinese patent application case of CN102260003A, it is to be placed in the reactor inner chamber be used to the membrane separation assemblies of tackling the catalyzer titanium dioxide fine particles, be immersed in and process among object liquid, and rely on the ozone bubbles that contains of ascension to wash away membrane separation assemblies, removing by this its surface adsorbs, the catalyst particles be detained, reach the recovery of catalyst particles, the recycling purpose, simultaneously, membrane separation assemblies is also to rely on this mode self-cleaning and keep its separating power, so, based on this structure, can only select business curtain formula hollow fiber film assembly or plate film assembly, and, this membrane separation assemblies is need to be immersed in the context of strong oxidizing property of ozone bubbles ascension, therefore, tolerance against oxidative power to membrane separation assemblies must have requirement, the organic membrane separation assembly of common material can not tolerate such environment for use, therefore can only select the membrane separation assemblies of PVDF material, this point clearly illustrates that in open the 0009th section word of text of this case and claim 3, its material cost of the filter membrane of the tolerance against oxidative power that this kind needs are special is higher, common organic micro-filtration membrane module that its commercially available price also requires higher than the non-oxidation tolerance certainly, in other words, the frame mode of this case, cause the material of membrane separation assemblies to be limited to more expensive PVDF material.Have again, UV-light possible in device is revealed, may touch the organic membrane assembly, this also the organic membrane assembly material in claimed apparatus can resist ultraviolet light irradiation, from this point, based on the organization plan of this device, the material of organic membrane separation assembly also can only be limited in more expensive PVDF material.
The organic membrane assembly, compared to the ceramic filter assemblies, has its apparent advantage; About this point, for the personage of filtering technique specialty, be known, here do not launch to repeat.
Can so, under the prerequisite of using the organic material membrane module, bypass this PVDF filter membrane material limitation? this is the problem that needs solve, and this is one of problem.
Two of problem:
Scouring force in view of described ascension bubble, cleaning capacity is more weak, therefore, with its aperture of membrane separation assemblies that this cleaning mode is used in conjunction with, can only select other filter opening aperture of larger micro-filtration level, other filter opening aperture of this micro-filtration level is the 0.1-0.2 micron, about this point, in open the 0009th section word of text of this case and claim 3, have clearly and limit equally, this kind filter opening aperture limits, type selecting from the such membrane separation assemblies of this case, built-in and soak use-pattern, the self-cleaning method of ascension bubble, be inevitable, can only limit its filter opening aperture in the micro-filtration rank.In other words, this its scouring force of mode washed away with the ascension bubble, clean power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, thus, in this case device, the filter membrane aperture is limited between 0.1 micron-0.2 micron, is the inevitable choice of not discussing leeway.
The filter opening aperture of so-called 0.1-0.2 micron, if change a measure unit, corresponding is exactly the filter opening aperture of 100-200 nanometer; Is what concept that? with 100 nanometer filter opening apertures of its lower limit, its size of catalyst particles that it can be tackled must be more than 100 nanometers, and the catalyst particles that is less than 100 nanometers can't be blocked; In other words, the catalyst particles that is less than 100 nanometers will directly penetrate, by the filter opening of membrane module, sneak among the so-called water purification that the DeR device exports.
Particle diameter and the photocatalyst dosage form selection of the related photocatalyst of the ultraviolet catalytic DeR of need to having a talk now.
The professional person who is engaged in photocatalytic degradation research knows, with the photochemical degradation reaction of uv light induction, its catalyzer multiselect titanium dioxide fine particles catalyzer, at present, on laboratory level, developed the particle catalyst of the photodegradation based on the optically catalytic TiO 2 characteristic various in style, certainly, the photodegradation catalyzer that these different preparation methods form, its particle diameter is also various, its particle diameter of photocatalyst that different preparation methods make is little of 20 nanometers, and greatly to 100000 nanometer also is 100 microns, has, and wherein is no lack of the photocatalyst kind of excellent performance, but due to the restriction of the evaluation of performance permanent stability, preparation cost and the market expansion etc. aspect factor, most its deliverabilities of described photocatalyst only are confined to laboratory level, and there is no to form extensive commercially available production level, at present known can make a big purchase in large quantities commercially available can actual a large amount of photocatalysts for the UV-light wave band that use be famous gas phase titanium dioxide P25, its concrete art-recognized meanings of gas phase titanium dioxide P25, the insider knows, does not here launch to repeat, the median size of gas phase titanium dioxide P25 is 21 nanometers, gas phase titanium dioxide P25 performance is not very optimum, but, its stable performance, key is on market, to make a big purchase in large quantities and to obtain, and can on technical scale, use in a large number, therefore, in photochemical catalysis specialized laboratory also usually with the P25 catalyzer be used as weighing various self-made photocatalyst catalytic performances with reference to pointer or contrast pointer, in fact, characteristics in view of the ultraviolet catalytic DeR, the photocatalyst that dispersity is higher, the needs that are applicable to this type reaction, that is to say, median size is in its catalyst interfacial area that can provide of photocatalyst of 21 nanometer left and right, the anti-settling ability, catalytic performance permanent stability etc. aspect, comprehensive, optimal.Say simply, at present, good and cheap, the photocatalyst of the UV-light wave band of the ready-made commercially available commercial grade that can actually make a big purchase in large quantities, use, be exactly median size be the gas phase titanium dioxide P25 catalyzer of 21 nanometers; At plant-scale application, this median size is that the photocatalyst of 21 nanometers is actual first-selections.
Above address, the disclosure number is the Chinese patent application case of CN102260003A, it is be used to tackling the membrane module of photocatalyst, that the stripping film assembly surface that washes away with the ascension bubble is adsorbed, the catalyst particles of deposition, yet, its scouring force of mode that this kind washes away with the ascension bubble, clean power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, therefore, in this case device, the filter membrane aperture is limited at micro-filtration filter opening rank between 0.1 micron-0.2 micron, change a measure unit, in this case device, the filter membrane aperture is limited at the micro-filtration filter opening rank between 100 nanometers-200 nanometer, this is the inevitable choice of not discussing leeway, this case can't tackle without the micro-filtration filter opening between selectable 100 nanometers-200 nanometer the gas phase titanium dioxide P25 particle that median size as above is 21 nanometers certainly, so, if use the P25 photocatalyst, this catalyzer will can't be tackled fully, and flows in so-called water purification, forms secondary pollution, certain heavy losses that also cause catalyzer and unrenewable, even if use other kind for this reason and the titanium dioxide optical catalyst of special large particle diameter, in its use procedure, collide or collide with wall because of mutual, must also can produce a large amount of small particle size fragments, wherein particle diameter is less than the fragment of 100 nanometers, can not be tackled by the micro-filtration filter opening between 100 nanometers-200 nanometer equally, these small shredss also can see through its membrane module and enter among so-called water purification, form secondary pollution.
Visible, the disclosure number is the Chinese patent application case of CN102260003A, and the cleaning solution of its scheme of interception structure for the photocatalyst particulate and related film assembly is all undesirable.
Therefore, how, under the prerequisite of this case advantage of incorporating things of diverse nature, reaching meticulous interception and recycling for the photocatalyst particulate, is an important topic very worth thinking deeply about, and this is two of problem.
Three of problem:
We know, liquid water body itself also can absorb the energy of microwave, and cause itself temperature-rise effect of processed liquid water body, and this temperature-rise effect of following wastewater treatment process and occurring, it not but the situation that we expect, in other words, microwave energy from magnetron is not used to excite electrodeless ultraviolet lamp fully, and have quite a few only be used to the microwave energy that excites electrodeless ultraviolet lamp, to be dissipated in described temperature-rise effect, the temperature-rise effect that this kind is not fond of has caused unnecessary microwave energy to waste, the apparatus structure scheme of showing in view of the above-mentioned publication number Chinese patent application case that is CN102260003A, its rational approach, can only be by the volume that reduces the microwave and photo catalysis reactor, to reduce in other words single tank processing capacity to reach the purpose that weakens the unnecessary dissipation of microwave, about this point, clear suitable size of having expressed about this apparatus structure integral body in this its embodiment of CN102260003A application case, what its expressed preferred size was corresponding is exactly a device that profile is very little, so, thus, 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 absorbs is relatively also little, with it accordingly, the wastewater treatment capacity of single tank is therefore also little, more particularly, the corresponding internal capacity of device suitable size expressed in embodiment is 40 liters, be also that single tank wastewater treatment capacity is 40 liters, namely 0.04 cube, in other words, it is once a complete set of, substantial length of operation has only solved the trade effluent of 0.04 cube, so, just need to carry out many times by the repetition of head to the operation of the complete set of tail, its treatment capacity cumulative just has plant-scale meaning, so to say, just individual analogy roughly, its preferred structure size of this case is 0.04 cube of such wastewater treatment capacity of single tank of correspondence roughly, need to repeat 1000 times by the complete set of head to tail, substantial length of operation, its accumulation amount, just can reach 40 cubes such one have industrial level wastewater treatment capacity, so excessively loaded down with trivial details repetitive operation will cause manpower, the serious waste of material resources, visible, its actual wastewater degradation processing efficiency of scheme that this kind showed by CN102260003A may not be fully up to expectations.Therefore, how not cause more microwave energy wastes or to reduce under the prerequisite of microwave energy waste, increase single tank wastewater treatment capacity, reduce the unnecessary too many by the repetitive operation number of times of head to tail of this intermittent type wastewater treatment equipment, improving its waste water treatment efficiency, is a significant technical problem merited attention.
On the other hand, according to the literature, some system, in the situation that the direct irradiation wastewater liquid of microwave, the photochemical catalysis degradation efficiency truly has raising, that is to say, in some system, between the direct irradiation wastewater liquid of microwave and photochemical catalysis degraded, there is certain coupling.
Therefore, how to take into account under the prerequisite of described coupling, improving the processing efficiency of wastewater degradation device, be worth inquiring into, this is three of problem.
Four of problem:
The scheme that this kind showed by CN102260003A, the bubble of the inner dispersed ascension of its retort, for the cyclic motion of the relative big scale of driving a reaction tank internal liquid, contribute slightly inadequate; Certainly, this weak point, in fact corresponding small size, the low capacity device of clear expression in CN102260003A scheme such as its embodiment, the impact that almost has nothing observable.From plant-scale application demand, undersized device that can not the divergence process amount does not have great magnetism certainly; So, as a kind of possibility, if there is certain mode can realize the significantly expansion for the treatment of capacity, under this situation, its importance of the cyclic motion of the relative big scale of retort internal liquid will highlight naturally; Imagining the possibility that this treatment capacity is significantly expanded, so, how to strengthen the cyclic motion of the relative big scale of retort internal liquid, is exactly an individual problem certainly, and this is four of problem.
Five of problem:
Photochemical catalysis oxidizing reaction for the UV-light wave band, there is following so several key element can have influence on the efficiency of this kinds of oxidation reaction, first ultraviolet wavelength, intensity, it two is particle diameters of photocatalyst, the usage quantity of photocatalyst in the unit volume reaction solution, himself catalytic performance etc. of photocatalyst, it three is that oxidized object is organic concentration in water body, oxidation complexity that the organic molecule structure determines himself etc., it four is sufficient degree of oxygen atmosphere, in the situation that other condition is identical, the sufficient degree of oxygen atmosphere, will become a very important key element that affects photochemical catalysis oxidative degradation ability.
The scheme of showing as CN102260003A, its numerous micro porous aeration head disperseds that are placed in reactor inner chamber bottom are in bottom, and by its alleged water distribution board, make the effect of this micro porous aeration head dispersed arrangement become more very, certainly, this is for the situation of the oarse-grained micron-sized photocatalyst that uses relatively easy sedimentation, really there is its favourable one side, but, from another side, the mode that this micro porous aeration head dispersed arranges, the supply of oxygen atmosphere too disperses, and in fact need most enhanced oxygen blowing zone be the effective area of photochemical catalysis oxidation, because the Effective depth penetration of short wave ultraviolet in liquid water body only has 20 centimetres of left and right, therefore, needing most enhanced oxygen blowing in fact is exactly the zone within peripheral approximately 20 cm distance of silica tube with the effective area that promotes photochemical catalysis oxidation process, in other words, zone within peripheral approximately 20 cm distance of silica tube is really to need enriched with oxygen atmosphere to supply with the zone ensured, this regional oxygen atmosphere is supplied with stronger, oxidizing reaction is also just carried out sooner, especially especially, in the microwave excitation mode, produce electrodeless ultraviolet emission, its characteristics can be accomplished high-power, high strength exactly, this is the strong point of this lamp type of electrodeless ultraviolet lamp, yet, just because of the superpower of its uv-radiation, high strength just more need to mate with powerful oxygen atmosphere supply capacity, otherwise, that powerful uv-radiation ability is really just that major part has been wasted.Above address, the scheme of showing as CN102260003A, factors has limited its reactor size, limited its actual treatment capacity, just as in its specific embodiment, clearly illustrating that, that can only be the little reactor that a single tank single treatment amount only has 40 liters of left and right, at so little reactor, in the situation of little inner chamber, because size itself is just very little, so, its shortcoming aspect photochemical catalysis oxidation effective area oxygen supply concentration degree, just can not be so obvious, even can ignore, can regard a non-existent problem at all more even fully as, in the face of such undersized little reactor, shortcoming problem about oxygen supply concentration degree aspect, not may float mind, but, imagine, if can overcome described many limiting factors, if can there be one of way actual implementation large-scale, the reactor of high throughput, within so above-mentioned silica tube periphery 20 cm distance, effective area oxygen supply strengthening problem will show especially out, especially for the situation of using electrodeless ultraviolet lamp as UV source, within above-mentioned silica tube periphery 20 cm distance, effective area oxygen supply strengthening problem is not allowed to despise more, therefore, how among the structure of possible large-scale photo-catalytical oxidation DeR device, strengthen the oxygen supply concentration degree of described effective area, improve the usefulness of wastewater degradation equipment, the problem that individual exactly needs are kept a close watch on, this is five of problem.
Six of problem:
Within this CN102260003A scheme pumps air into the silica tube that includes electrodeless ultraviolet lamp, reach the aeration-cooling of electrodeless ultraviolet lamp, cooling purpose, and those flow through the air of silica tube, because being subjected to ultraviolet irradiation, some air can change ozone into, therefore, from the air flowed out silica tube, be exactly the air that contains some ozone certainly, this scheme contains ozone-air by this and is transferred to and is positioned at reactor below micro porous aeration head, and disengage from micro porous aeration head, at these, contain in ozone bubbles ascension process from bottom to top, wherein contained ozone can meet with and occur redox reaction with the organic molecule that runs among distance, this redox reaction can consume a part of ozone certainly, this be do not have doubt, but, above address, the scheme of showing as CN102260003A, the many effects limit that can't ignore that certainly exist its reactor size, limited its actual treatment capacity, just as in its specific embodiment, clearly illustrating that, that can only be the little reactor that a single tank single treatment amount only has 40 liters of left and right, at so little reactor, in the situation of little inner chamber, because overall dimension itself is just very little, so, the longitudinal size of its reactor inner chamber or regard that to contain the liquid degree of depth can only be also a very little size as with reckoning in every item, this size is if clearly illustrated that among its embodiment, only have about 40 centimetres, the Sheng that the reckons in every item liquid degree of depth also just only has 40 centimetres, in fact contain the liquid degree of depth and certainly be less than this number, just with the Sheng liquid degree of depth of 40 centimetres, analyze, so, is this Sheng liquid degree of depth of 40 centimetres what concept? that is to say, contain the ozone-air ascension and only have short 40 centimetres by the path of waste water, this path is too short, containing the ozone-air bubble passes through at a gallop and only only has 40 centimetres of dark water bodys, too short duration of contact with water body, contained ozone in bubble, can only there is a very little part to be used to the oxidative degradation organism, and most ozone is in fact just passed by liquid simply, from liquid level effusion emptying through exhaust port, briefly, the oxygenizement potentiality major part of these ozone has been wasted, and, overflow, in fact the ozone be wasted can cause unnecessary atmospheric pollution, the main contriver of this case once contained ozone-air via micro porous aeration head to squeezing in one meter dark tank with the normal domestic use ozone machine, in the situation that the depth of water degree of depth reaches one meter, still can near the water surface, obviously smell the smell of ozone, visible, that 40 centimetres of dark Sheng liquid degree of depth are obviously to be not enough to utilize fully ozone, visible, for the such equipment of electrodeless ultraviolet light chemical catalysis wastewater degradation reactor, ozone utilizes incomplete problem also to need to pay close attention to, obviously, people more expect be the ozone utilization more fully, the contaminative exhaust emissions still less without extreme ultraviolet wastewater degradation reactor, this is six of problem.
Seven of problem:
Its running of waste water catalytic degradation reaction device, require the expenditure of energy, and therefore, operator are bound to wish, when the wastewater degradation reaction proceeds to terminal, can impartially, immediately not stop too early continuing Implantation Energy to inside reactor only lately; If it is too early to stop the moment of Implantation Energy, wastewater degradation is incomplete; And if reach already reaction end, but still unceasingly to the inside reactor Implantation Energy, that is certainly at the valuable energy of waste.Its structure of CN102260003A scheme as this case technical background can not provide any instant information constantly to the wastewater degradation reaction end, so, just can only estimate by experience the terminal of wastewater degradation reaction; And estimate by experience the terminal that wastewater degradation reacts, that obviously can not be satisfactory; So, how for the wastewater degradation reaction end, constantly make neither in advance also undelayed instant information output, and immediately close the energy input to reactor in the just right moment, the technical threshold that can not despise exactly, this is seven of problem.
Eight of problem:
Accept the described trade effluent of microwave and photo catalysis degradation treatment, the material that wherein is mingled with unavoidably some metal particles that originate from mechanical system abrasion process and carbon granules and so on, even if quantity is small, its existence almost is difficult to avoid, the disclosure number is that the described organic membrane separation assemblies in the Chinese patent application case of CN102260003A is installed in the microwave and photo catalysis reaction zone, being installed in wherein do not stop microwave certainly be used to intercepting ultraviolet dividing plate between silica tube and membrane separation assemblies, so, the practical function zone of microwave must cover zone that organic membrane separation assemblies is installed described in this scheme, working mechanism based on membrane separation assemblies, its accumulation process on the organic top layer of membrane separation assemblies of the particulate of metal particle as above and carbon granules and so on is difficult to avoid, and the particulate of this type of described metal particle and carbon granules and so on, the good absorption medium of microwave energy exactly, absorbed the particulate of the described metal particle of accumulation state of microwave energy and carbon granules and so on, nature can to the top layer of its organic membrane separation assemblies of being close to produce based on heat penetration erosion mechanism continue pierce destruction, as mentioned above, due to the structures shape of this its device of CN102260003A application case can only select the polyvinylidene fluoride film material, approximately 140 degrees centigrade of this polyvinylidene fluoride film material heatproofs, really high more many than general film material heatproof, yet, the heat penetration erosion effect that its point-like of particulate that has absorbed the described metal particle of accumulation state of microwave energy and carbon granules and so on is pierced formula very easily breaks through the heatproof temperature limit of this polyvinylidene fluoride film material, for above-mentioned reasons, well imagine, pvdf membrane material in its device of this CN102260003A application case will be significantly less than the desirable work-ing life of expecting its actual service life, the structure of this its device of CN102260003A application case, determined under this structural framing, the heat penetration erosion destruction problem that above-mentioned point-like is pierced formula can't be avoided, therefore, how to get around the heat penetration erosion destruction problem that this point-like is pierced formula, also need to consider, this is eight of problem.
Nine of problem:
The disclosure number is the Chinese patent application case of CN102260003A, its specification sheets open text text the 0008th section word and claim the second, catalyst particle size scope for its device can be suitable for, have a restriction, and this particle size range is defined as 20 nanometers to 100 micron.We know, under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; Especially for the section of those less particle diameters among this particle size range, easily occur because of presetting not in place, the incorrect agglomeration traits caused of pH value of pH value especially; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out the depolymerization running for coacervate; Yet we do not see that any helping immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem among this CN102260003A scheme.For as the CN102260003A scheme, because of factors restriction, can only being the reactor of small scale structures just like that, still can manually directly mention reactor, topple over and inspect in the reactor outside, process above-mentioned reunion situation, so, if likely expand its capacity, just so to say, if be several cubes of large-scale reactor or the huge reactors to dozens of cube, that is not obviously manual to have toppled over problem that its operation can tackle, so, the situation of mutually reuniting for this catalyst particles, how to realize instant original position disposal, it is exactly a technical problem, this is nine of problem.
Ten of problem:
In the disclosure number, be in the expressed apparatus structure of the Chinese patent application case of CN102260003A, for screen, protect the silica tube of electrodeless ultraviolet lamp, its outer wall, refer to the outer wall of silica tube, through for a long time with the contacting of processed trade effluent, incrustation gradually unavoidably, the long-pending material of dirt are mainly difficult by mineral-type impurity that light-catalyzed reaction touched certainly, incrustation phenomenon because this mechanism forms, be easy to be observed after the equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, although be very thin one deck, also be enough to ultraviolet radiation to electrodeless ultraviolet lamp and cause significantly and stop, this will cause the actual treatment effect of this microwave and photo catalysis reaction treating device significantly to reduce; In its reactor, the bubble of dispersed ascension is because too disperseing, wash away strength a little less than, if only rely on this bubble relatively disperseed to maintain the bright and clean of silica tube surface, really undertake to do what is apparently beyond one's ability, in other words, the bubble that this relatively disperses, it is weak washes away the incrustation process that strength still is not enough to stop fully this silica tube surface; In the use procedure of laboratory yardstick, above-mentioned incrustation problem is subtle, and still, on the industrial application yardstick, this incrustation problem certainly will highlight; Therefore, how, under the prerequisite of not tearing machine open, immediately, effectively remove the dirty lamination on this silica tube outer wall, maintain the high-level efficiency continued of this microwave and photo catalysis treatment unit, this problem is also very important, and this is ten of problem.
11 of problem:
This problem is nine its problems that derived of the problem above addressed.Front is spoken of, and under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; The section of those less particle diameters among its suitable catalyst particle size range of especially touching upon for this CN102260003A scheme, easily occur because of presetting not in place, the incorrect agglomeration traits caused of pH value of pH value especially; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out the depolymerization running for coacervate; Based on this its framework of CN102260003A scheme, operator can't perceive the situation that described reunion occurs inside reactor immediately, thereby also can't make instant disposal, thus, this is subjected to the factors restriction and can only is the further reduction of its limited usefulness of reactor of small scale structures; Therefore, among the application running of reactor, particularly, for example, among the application of possible large-scale reactor or huge reactor running, the awareness inside reactor catalyst particles main inducing parameter of reuniting how immediately, be a key issue, this is 11 of problem.
12 of problem:
Based on this its framework of CN102260003A scheme, restriction due to the factors of having addressed, its reactor can only be the smaller reactor of undersized treatment capacity, the useful size of reactor inner chamber is certainly also smaller, among its structure of reactor inner chamber, can be used in the spatial altitude of settling curtain type film assembly is approximately also 30 centimetres of left and right, so, even if just adopt the very curtain type film assembly of small breadth, also almost up and down two head on plug in reactor the inside, little treatment capacity due to reactor, small size, so, after its DeR completes, under the situation of getting rid of from inside to outside liquid, its curtain type film assembly is exposed in air unavoidably, although each time exposed can be not long, but, the accumulation result of often buying and selling, make exactly this curtain type film assembly with air, contact too much, its normal service requirements of curtain type film assembly, under submerged state, to use fully, that is to say, must be that hygrometric state is used, if curtain type film assembly contacts with air too much, can make it more aging than more quickly, Performance Ratio is decayed more quickly, and the situation that this curtain type film assembly contacts with air too much, under this its framework of CN102260003A scheme, can't avoid, therefore, how to protect be used to tackling the membrane module of catalyzer, can under nominal situation, use, can avoid too much the contacting with air, to safeguard its normal usage energy, guarantee its normal service life, problem that needs are faced exactly, this is 12 of problem.
13 of problem:
Based on this its framework of CN102260003A scheme, among its running, the granules of catalyst of being tackled by curtain type film assembly, a part is at the curtain type film assembly surface deposition, and another part is trapped among liquid phase, causes thus granules of catalyst concentration in liquid phase progressively to raise along with progressively reducing of liquid phase volume, this is for follow-up membrane sepn, its membrane sepn load also can raise thereupon gradually, and before and after this membrane sepn load, the excessive problem of difference needs to solve, and this is 13 of problem.
14 of problem:

The described spatial domain of this case one word refers to ,Jie territory, space.
Advantage of the present invention is, partition is forced in microwave exposure spatial domain to the wastewater degradation inside reactor, this case is protected electrodeless ultraviolet lamp and screen thereof with silica tube and is shrouded in it with metal cage, metal cage retrains the effect spatial domain of microwave simultaneously, so, spatial domain between silica tube outer wall and metal cage inwall has formed a microwave excitation and has promoted the wastewater degradation zone with the photochemical catalysis coupling, and, the multiple hole of metal cage or the structure of many meshes, do not affect waste water and reactor lower part bubbling and on air free into and out of this spatial domain; And the spatial domain between metal cage and reactor wall, the waste water water body is contained the simple pyrogenicity absorption of microwave, has significantly weakened thus the unhelpful dissipation of microwave energy; This case method force to be cut off the microwave exposure spatial domain of wastewater degradation inside reactor, and based on this, this case method allows, by significantly expanding the design volume in irradiation spatial domain a little less than this microwave zero irradiation spatial domain or microwave, to realize the significantly expansion of single tank reactor volume; This case method allows reactor list tank wastewater treatment capacity significantly to promote, and need not worry that microwave energy dissipates too much in unhelpful waste water water body temperature-rise effect again.
Rely on this case method, the design volume of microwave and photo catalysis wastewater degradation reactor is that single tank wastewater treatment capacity can be expanded to several cubes to dozens of cube; The volume that even single tank is hundreds of cubes, also allow; Rely on this case method, after expansion reactor for treatment capacity, can reduce significantly the frequency of the wastewater degradation operation of equipment of a complete set, whole process, be conducive to the saving of human and material resources.
This case method is under the prerequisite of taking into account described microwave and photochemical catalysis coupling, for the significantly expansion of relevant its design capacity of wastewater degradation reactor provides a broad space.
On the other hand, among this case method, its high-density ascension bubble flow discharged of described cluster-shaped micro porous aeration head cluster, in the ascension that makes progress, and wrapped folder, carry, guided liquid-flow, form a kind of motion that is similar to the fountain form, in this kind motion, the high-density air burble wrapped folder that is derived from described cluster-shaped micro porous aeration head cluster liquid to the metal cage region gush and on, and then relatively concentrated area is impacted in metal cage, outer close position, be subjected to described high-density air burble wrapped folder, the liquid stream carried is impacting, in metal cage, after outer close position, liquid layer by top area spreads to surrounding, via neighboring area, sink, arrive reactor intracavity bottom zone, again through the wrapped folder of its high-density ascension bubble flow discharged of described cluster-shaped micro porous aeration head cluster, carry, continue the motion that it is similar to the fountain form, so circulation endlessly, the liquid circulation campaign of this relative big scale guided, help to guarantee the homogenizing of inside reactor liquid degradation reaction process, and this,, for large-scale electrodeless ultraviolet light catalysis DeR device, is necessary.
Its UV source of this case method is to rely on microwave excited electrodeless ultraviolet lamp, the uv-radiation characteristics of this lamp type can be accomplished high-power, high strength exactly, yet the Effective depth penetration of ultraviolet ray in liquid water body only has 20 centimetres of left and right, therefore, zone within peripheral approximately 20 cm distance of silica tube is the effective area of photochemical catalysis oxidative degradation, and this zone is also simultaneously the efficient zone of microwave excitation promotion and the coupling of photochemical catalysis oxidative degradation; Partly or entirely being coated by permeable, the ventilative also metal cage of printing opacity of this effective area; This case method is to be positioned at the described cluster-shaped micro porous aeration head cluster under metal cage, come concentrated area to discharge highdensity ascension bubble flow, make its as concentrated area as fountain towards as described in effective area discharge, the oxygen atmosphere that this method helps to improve described effective area is supplied with intensity, helps the accelerated degradation reaction process.
Based on this case method, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, to realize by significantly expanding the design volume of irradiation zone a little less than microwave zero irradiation zone or microwave, so, the lateral dimension of reactor, longitudinal size is all significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., in the situation that the Sheng liquid degree of depth is enough dark, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust up hill and dale ozone contained in bubble, thus, containing ozone composition oxidation potential in the ozone-air bubble utilizes incomplete problem to be solved, and, because long ascension path causes ozone to exhaust, in reactor tail gas, just can not be entrained with again the ozone that can cause environmental pollution.
This case method is with external multistage filter, reach the interception step by step to the collision fragment of the small scale from coacervate macrobead to ten number nanometers of catalyst particles, be close to recovery, reuse photocatalyst up hill and dale, be close to the secondary pollution of taking precautions against catalyst loss up hill and dale and causing; This is hold-up interception method can protect secondary filter to make its filtration passage avoid the rigid obstruction of large particulate matter step by step; Wherein the pre-filtering aperture of the first step is between 5 microns and 300 microns, and its aperture of the micro-filtration of the second stage is between 25 nanometers and 1000 nanometers, and its aperture of the ultrafiltration of the third stage is between 15 nanometers and 2 nanometers; Such hold-up interception method, can fully tackle nano level photocatalyst, and it certainly can be close to and tackle up hill and dale this median size of gas phase titanium dioxide P25 is the catalyzer of 21 nanometers; Preamble is addressed, the gas phase titanium deoxide catalyst of nano level P25 and so on, it is the commercially available catalyzer that can buy in a large number, also weather resistance, stability, the known good photocatalyst of UV-light wave band photocatalysis performance, certainly, it is also in industrial scale applications, in fact to pay the utmost attention to the photocatalyst of selecting; This case catalyzer hold-up interception method is complementary with the virtual rating of catalyzer market supply, actual kind, merges mutually.
And, in this case method, catalyzer interception mechanism is external mechanism, and based on the method, its filter core needn't be soaked in the liquid of the strong oxidation of inside reactor, strong uv irradiation, therefore, can needn't consider the tolerance to uv irradiation, strong oxidizing condition fully, like this, just there is no the restriction aspect extraordinary tolerance selecting of filter core material, can on more vast optional material kind, select, and need not be confined to again the material of more expensive PVDF and so on fully.
Related strainer at different levels all has commercially available, commercially available strainers at different levels, the discharge outlet of draining-off sewage when its sewage draining exit is exactly back flushing, this class back flush type equipment is used in this case, to tackle step by step catalyst particles, originally the sewage draining exit of commercially available relevant device, be used as being held back the recycling delivery port of catalyst particles or refluxing and use delivery port again by conversion in this case method.
Above address, based on this case method, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, to realize by significantly expanding the design volume of irradiation zone a little less than microwave zero irradiation zone or microwave, so, from the appearance, the lateral dimension of reactor, longitudinal size is all significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., in the situation that the Sheng liquid degree of depth is enough dark, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust up hill and dale ozone contained in bubble, thus, containing ozone composition oxidation potential in the ozone-air bubble utilizes incomplete problem to be solved, and, because long ascension path causes ozone to exhaust, in reactor tail gas, just can not be entrained with again the ozone that can cause environmental pollution, only ought be subject to processing reducing substances in water body is in organic pollutant is degraded totally, in water body, again without the organic pollutant that can supply ozone oxidation reaction, those unnecessary ozone just likely no longer consume and see through long ascension path effusion liquid level, front is spoken of, among some problems that this case solves simultaneously one, it is the circulation of the relative big scale of enhanced reactor internal liquid, this systemic circulation mechanism of having strengthened has been facilitated the uniformity of its contained organic pollutants DeR process of inside reactor liquid, thus, allow at its corresponding framework of this case method several cubes to dozens of cube even under the processing capacity framework of hundreds of cube volume, above the inside reactor liquid level, have in the ozone effusion, the DeR that namely shows inside reactor has reached terminal, and be the terminal that the whole uniformity of internal liquid ground reaches DeR, this terminal point determining factor is that the condition that can provide with this case scheme is complementary, this case is at its exhaust port position installing ozone sensor of reactor, in this locations of structures, ozone detected, just mean that the inside reactor DeR reaches home, ozone sensor and connecting with the composite structure of ozone content indicating meter with ozone attention device or ozone content indicating meter or ozone attention device, for to operator, providing indication information accurately, this case and the electric signal that ozone sensor is exported send power-supply controller of electric to by cable, this power-supply controller of electric also connects with magnetron and pneumatic pump respectively by cable, power-supply controller of electric carries out the power switch action according to its received described electric signal, certainly, its function mode is, at power-supply controller of electric, receive in the signal that ozone that ozone sensor sends overflows, automatically close the power supply that leads to magnetron and pneumatic pump, this case Using such method, can know the terminal of inside reactor DeR process in time, and Using such method, when reaction reaches terminal, automatically close the power supply of magnetron and pneumatic pump, stop in time, to the inside reactor Implantation Energy, so can avoiding unnecessary energy dissipation, and, this case Using such method, in DeR reaches home, can close in time the power supply of described magnetron and pneumatic pump, this power-off action is synchronous, the same generation process of ozone that stopped in a flash also, because ozone generation process is stopped in time, just do not have over a large amount of ozone that need and disengage from described exhaust port, thereby avoided unnecessary secondary pollution or said secondary pollution, this case method has determined that its corresponding framework does not have ozone more than needed can supply discharge.
Rely on this case method, the microwave exposure spatial domain of inside reactor is subject to forcing to cut off, limit, this case and adopt the multistage backwash filter of external cascade to carry out the meticulous interception for catalyst particles, among this method, back flush type hollow fiber microfiltration membrane assembly and back flush type polysulfone hollow fiber ultrafiltration membrane system are all by external and away from reactor core, microwave can not shine described membrane module fully, based on this case the method, got around described point-like fully and pierced the heat penetration erosion destruction problem of formula, this problem is settled properly thus.
This case method is moulded reactor inner chamber bottom surface makes it hollow gradually to central zone by periphery, and described hollow its gradient is between 5 degree and 35 degree, this case method is also installed ultrasonic transducer on the outer side position of described hollow its innermost corresponding part reactor diapire or medial surface position, above address, this case method and be beneficial to the cyclic motion that driving a reaction device internal liquid is made relative big scale, the mode of this liquid circulation campaign are that peripheral liquid sinks, and middle liquid rises, and so constantly moves in circles, above address, under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness, especially for the section of those less particle diameters among this particle size range, easily occur because of presetting not in place, the incorrect agglomeration traits caused of pH value of pH value especially, for the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out the depolymerization running for coacervate, at catalyst particles, occur under serious situation of reuniting, the heavier macro aggregate of wherein some is due to action of gravity, tend to gradually to the sedimentation of reactor intracavity bottom, this case method is moulded reactor inner chamber bottom surface makes it be hollow pattern, and, the cyclic motion of described relative big scale can driving a reaction device internal liquid be made in its enforcement of this case method, the effect of this systemic circulation campaign is together with the effect of ubiquitous natural gravity, the macro aggregate of sedimentation can be pushed away along the slope, bottom surface of described hollow pattern and sweep to hollow innermost and make them be gathered in there, the ultrasonic transducer that this case method is installed is positioned at this hollow innermost position just, this hollow innermost zone, it is the final zone of assembling of described macro aggregate, also that ultrasonic wave can be damply minimum simultaneously, closest range ground, the most consumingly, for macro aggregate, carry out depolymerization running zone most effectively, this case the method can allow with minimum ultrasonic energy loss, realizes maximized ultrasonic depolymerization effect, this case Using such method, can converge the coacervate sediment, and, in the most concentrated zone of coacervate sediment, implement the depolymerization running, based on the method, the ultrasonic wave that is derived from reactor bottom also can be radiated other zone in inside reactor liquid simultaneously certainly, and those smaller coacervates that still are in suspended state are being brought into play to unzipping, its running of this case associated ultrasonic Splitting by radiation is the running that can start as required or close, this case method has realized disposing for the instant original position of catalyst particles aggregate.
