Description

Rely on the photochemical catalysis wastewater degradation reactor of microwave excitation UV source

Technical field

The present invention relates to a kind of photochemical catalysis wastewater degradation reactor that relies on microwave excitation UV source, belong to C02F technical field of waste water processing.

Background technology

Microwave and photo catalysis degradation treatment technology, effectively for the innoxious process for treating containing organic pollutant trade effluent, quite concerned in recent years as a kind of.

About microwave and photo catalysis degradation technique, as an example, the Chinese patent application case that can be CN102260003A referring to publication number.

The disclosure number is the Chinese patent application case of CN102260003A, to using microwave as excitaton source, excite electrodeless ultraviolet lamp transmitting 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 being 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 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 with this membrane separation assemblies, realize holding back again of photocatalyst titanium dioxide fine particles and use, this scheme is also set up dividing plate between non-polar ultraviolet light source and membrane separation assemblies, for 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 is certainly for very important pushing effect has been played in the progress of microwave and photo catalysis wastewater degradation technology, and the work that its research staff launches in this field is admirable.

The meaning of the admiration based on sincere, and, common striving direction, what below us, will talk is problem.

The problem that below will speak of, has 14; This ten four problems is ten four 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 reactor inner chamber for tackling the membrane separation assemblies of catalyzer titanium dioxide fine particles, be immersed in and process among object liquid, and what rely on ascension washes away membrane separation assemblies containing ozone bubbles, removing by this its surface adsorbs, the catalyst particles being detained, reach the recovery of catalyst particles, recycling object, 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 curtain formula hollow fiber film assembly or plate film assembly for business, 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 of word of text of this case and claim 3, its material cost of filter membrane of the tolerance against oxidative power that this kind of needs are special is higher, common organic micro-filtration membrane module that its commercially available price also requires higher than non-oxidation tolerance certainly, in other words, the frame mode of this case, causes 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 organic membrane assembly, this also the organic membrane assembly material in claimed apparatus can resist ultraviolet light irradiation, from this point, organization plan based on this device, the material of organic membrane separation assembly also can only be limited in more expensive PVDF material.

Organic membrane assembly, compared to 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.

So, using under the prerequisite of organic material membrane module, bypass this PVDF filter membrane material limitation? this is the problem that needs solve, and this one of is problem.

Two of problem:

Scouring force in view of described ascension bubble, cleaning capacity is more weak, therefore, can only select other filter opening aperture of larger micro-filtration level with its aperture of membrane separation assemblies that this cleaning mode is used in conjunction with, other filter opening aperture of this micro-filtration level is 0.1-0.2 micron, about this point, in open the 0009th section of word of text of this case and claim 3, have clearly and limit equally, this kind of 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 micro-filtration rank.In other words, this its scouring force of the mode of washing away with ascension bubble, clean power too a little less than, to such an extent as to cannot tackle the more filter membrane of small-bore at all, thus, in this case device, 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; Does 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 cannot be blocked; In other words, the catalyst particles that is less than 100 nanometers is by directly penetrating, by the filter opening of membrane module, sneaks among the so-called water purification that 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 photodegradation particle catalyst based on 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 is also 100 microns, has, and is wherein 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 are only 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 UV-light wave band that use be famous gas phase titanium dioxide P25, its concrete art-recognized meanings of gas phase titanium dioxide P25, 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 in technical scale, use in a large number, therefore, in photochemical catalysis specialized laboratory also usually with P25 catalyzer be used as weighing various self-made photocatalyst catalytic performances with reference to pointer or contrast pointer, in fact, feature in view of 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, 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 for tackling the membrane module of photocatalyst, that the stripping film assembly surface that washes away with ascension bubble is adsorbed, the catalyst particles of deposition, yet, its scouring force of the mode that this kind washes away with ascension bubble, clean power too a little less than, to such an extent as to cannot tackle the more filter membrane of small-bore at all, therefore, in this case device, 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, filter membrane aperture is limited at the micro-filtration filter opening rank between 100 nanometer-200 nanometers, this is the inevitable choice of not discussing leeway, this case cannot tackle without the micro-filtration filter opening between selectable 100 nanometer-200 nanometers the gas phase titanium dioxide P25 particle that median size as above is 21 nanometers certainly, so, if use P25 photocatalyst, this catalyzer will cannot be tackled completely, 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, because of mutual, collide or collide with wall, 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 nanometer-200 nanometers 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 it is all undesirable for the interception structure scheme of photocatalyst particulate and the cleaning solution of related film assembly.

Therefore, how, under the prerequisite of this case advantage of incorporating things of diverse nature, reaching meticulous interception and recycling for photocatalyst particulate, is an important topic very worth thinking deeply about, and this is problem two.

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, but not the situation that we expect, in other words, microwave energy from magnetron is not used to excite electrodeless ultraviolet lamp completely, and have quite a few should be only for exciting the microwave energy of 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 to reduce in other words by reducing the volume of microwave and photo catalysis reactor the object that single tank processing capacity is reached the unnecessary dissipation of reduction 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 contacting with microwave is little, the microwave energy that waste water absorbs is relatively also little, answer in contrast ground, 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, also be that single tank wastewater treatment capacity is 40 liters, 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 the repetition to the complete set operation of tail by head many times, 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 the complete set to tail by head of 1000 times, 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 the scheme that this kind shown 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 repetitive operation number of times to tail by head of this intermittent type wastewater treatment equipment, improve its waste water treatment efficiency, be a significant technical problem meriting attention, this is problem three.

Four of problem:

The scheme that this kind shown 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, contributes slightly inadequate; Certainly, this weak point, for CN102260003A scheme as in fact corresponding small size, the low capacity device of clear expression in its embodiment, the impact that almost has nothing observable.From plant-scale application demand, undersized device that can not 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 certainly an individual problem, and this is problem four.

Five of problem:

Photochemical catalysis oxidizing reaction for 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 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 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.

As the scheme that CN102260003A showed, 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, the effect of this micro porous aeration head dispersed arrangement is become more very, certainly, this is for the situation of the oarse-grained micron-sized photocatalyst of the relatively easy sedimentation of use, 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 region 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, need most enhanced oxygen blowing to promote that in fact the effective area of photochemical catalysis oxidation process is exactly the region within silica tube periphery approximately 20 cm distance, in other words, region within silica tube periphery approximately 20 cm distance is really to need enriched with oxygen atmosphere to supply with the region ensureing, this region oxygen atmosphere is supplied with stronger, oxidizing reaction is also just carried out sooner, especially especially, in microwave excitation mode, produce electrodeless ultraviolet emission, its feature 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, as the scheme that CN102260003A showed, factors has limited its reactor size, limited its actual treatment capacity, just as clearly illustrated that in its specific embodiment, 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 negligible, can regard a non-existent problem at all more even completely 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 a needs is kept a close watch on exactly, 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 object, and those flow through the air of silica tube, because being subject to ultraviolet irradiation, some air can change ozone into, therefore, the air flowing out from silica tube is exactly the air that contains some ozone certainly, this scheme should be transferred to and be positioned at reactor below micro porous aeration head containing ozone-air, 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, as the scheme that CN102260003A showed, the many effects limit that cannot ignore that certainly exist its reactor size, limited its actual treatment capacity, just as clearly illustrated that in its specific embodiment, 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 as 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 be certainly less than this number, just with the Sheng liquid degree of depth of 40 centimetres, analyze, so, does is this Sheng liquid degree of depth of 40 centimetres what concept? that is to say, containing ozone-air ascension, by the path of waste water, only have short 40 centimetres, this path is too short, containing ozone-air bubble, pass through at a gallop and only only have 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 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 being wasted can cause unnecessary atmospheric pollution, the main contriver of this case once squeezed into containing ozone-air via micro porous aeration head with normal domestic use ozone machine in one meter of dark tank, 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 to be obviously not enough to utilize completely 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 ozone utilization more completely, contaminative exhaust emissions still less without extreme ultraviolet wastewater degradation reactor, this is problem six.

Seven of problem:

Its running of waste water catalytic degradation reaction device, requires the expenditure of energy, and therefore, operator are bound to wish, when 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 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 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 wastewater degradation reaction end, constantly make neither also undelayed instant information output in advance, and immediately close the energy input to reactor in the just right moment, the technical threshold that can not despise exactly, this is problem seven.

Eight of problem:

Accept the described trade effluent of microwave and photo catalysis degradation treatment, the material that is wherein 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 is almost difficult to avoid, described organic membrane separation assemblies in the Chinese patent application case that the disclosure number is CN102260003A is installed in microwave and photo catalysis reaction zone, being installed in wherein do not stop microwave certainly for intercepting ultraviolet dividing plate between silica tube and membrane separation assemblies, so, the practical function region of microwave must cover region 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 metal particle and carbon granules and so on described in this type of, 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, the top layer of the organic membrane separation assemblies that can be close to it of nature 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 polyvinylidene fluoride film material, approximately 140 degrees Celsius 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 expected desirable work-ing life 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 cannot 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 problem eight.

Nine of problem:

The disclosure number is the Chinese patent application case of CN102260003A, its specification sheets open text text the 0008th section of word and claim the second, for the applicable catalyst particle size scope of its device institute energy, there is a restriction, this particle size range is defined as 20 nanometers to 100 micron.We know, under some pH value regulates not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles is easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; Especially for those sections of small particle size relatively among this particle size range, easily occur because of presetting not in place, the incorrect agglomeration traits causing of pH value of pH value especially; The situation of reuniting for this catalyst particles, is immediately to adopt an effective measure, and carries out the depolymerization running for coacervate; Yet we do not see that any contributing to immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem among this CN102260003A scheme.For if CN102260003A scheme is just like that because factors restriction can only be the reactor of small scale structures, still can manually directly mention reactor, topple over and inspect in reactor outside, process above-mentioned reunion situation, so, if likely expand its capacity, just so to say, if be several cubes to large-scale reactor or the huge reactor of 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 realizing instant original position disposes, 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 shielding the silica tube that protects 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 is mainly difficult by mineral-type impurity that light-catalyzed reaction touched certainly, incrustation phenomenon because this mechanism forms is easy to be observed after equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, although be very thin one deck, be also enough to the ultraviolet radiation of electrodeless ultraviolet lamp to 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 disperseing 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 is still not enough to stop completely this silica tube surface; In the use procedure of laboratory yardstick, above-mentioned incrustation problem is subtle, and still, on industrial application yardstick, this incrustation problem certainly will highlight; Therefore, how not tear open under the prerequisite of machine, immediately, effectively removing the dirty lamination on this silica tube outer wall, maintaining the lasting high-level efficiency of this microwave and photo catalysis treatment unit, this problem is also very important, and this is problem ten.

11 of problem:

Nine its derivative problems that this problem is the problem of above addressing.Before speak of, under some pH value regulates not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles is easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; Those among its suitable catalyst particle size range of especially touching upon for this CN102260003A scheme are the section of small particle size relatively, easily occurs because of presetting not in place, the incorrect agglomeration traits causing of pH value of pH value especially; The situation of reuniting for this catalyst particles, is immediately to adopt an effective measure, and carries out the depolymerization running for coacervate; Based on this its framework of CN102260003A scheme, operator cannot perceive the situation that described reunion occurs inside reactor immediately, thereby also cannot make instant disposal, thus, this is subject to 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 running of possible large-scale reactor or huge reactor, the main inducing parameter how immediately awareness inside reactor catalyst particles is reunited, be a key issue, this is problem 11.

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 and settle the spatial altitude of curtain type film assembly approximately also just 30 centimetres of left and right, so, even if just adopt the very curtain type film assembly of small breadth, also almost two heads on plug in reactor the inside up and down, little treatment capacity due to reactor, small size, so, after its DeR completes, getting rid of from inside to outside under the situation of liquid, its curtain type film assembly is exposed in air unavoidably, although each time exposing can be not long, but, the accumulation result of often buying and selling, make exactly this curtain type film assembly contact with air too much, its normal service requirements of curtain type film assembly, under submerged state, to use completely, 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, cannot avoid, therefore, how to protect for 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, a problem that needs are faced exactly, this is problem 12.

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 curtain type film assembly surface deposition, and another part is trapped among liquid object phase, causes thus liquid object middle granules of catalyst concentration progressively rising along with progressively reducing of liquid phase volume mutually, 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 problem 13.

14 of problem:

Based on this its framework of CN102260003A scheme, among its running, water pump to reactor inner chamber filling waste water, itself cannot differentiate inside reactor water level height, operator can only rely on experience or range estimation to close in time the pump motor of this filling waste water, if experience error or range estimation response are not prompt enough, be easy to occur, because of the excessive situation of overflowing reactor of waste water filling, cause thus unnecessary trouble; On the other hand, after DeR finishes, need to be by inside via curtain type film assembly to extracardiac pumping, failing to know under the situation of inside reactor water level, completely can only rule of thumb or estimate and judge the opportunity of closing down water pump, and running like this, obviously unreliable, very easily because experience is slipped up or range estimation responds not in time, causing this to draw water cannot shut down in time with water pump, and this dry tap, idle running are easy to cause this pump motor that draws water to burn, this problem can not be out in the cold, and this is problem 14.

At the bright finished punching stainless steel of employing, make microwave constrainer, or, adopt in the situation of bright finished Stainless Steel Wire cylinder mould as microwave constrainer, via complicated specular reflection mechanism, both all can transfer out the UV-light from electrodeless ultraviolet lamp to greatest extent, and make up to greatest extent himself entity of described microwave constrainer light is blocked, absorbs caused loss.

Structure based on this case, the design volume of 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 allows; Based on this structure of this case, can reduce significantly the frequency of a complete set, substantial length of operation, be conducive to the saving of human and material resources.

This case reactor is among its operation, its high-density ascension bubble flow discharging 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 fountain form, in this kind of motion, the high-density bubble stream wrapped folder that is derived from described cluster-shaped micro porous aeration head cluster liquid to silica tube region gush and on, and then more intensively impact, the effective area of the described photochemical catalysis oxidizing reaction by silica tube periphery, be subject to described high-density bubble stream wrapped folder, the liquid stream carrying is impacting, after described effective area by silica tube periphery, liquid layer by top area spreads to surrounding, via neighboring area, sink, arrive reactor intracavity bottom region, again through the wrapped folder of its high-density ascension bubble flow discharging of described cluster-shaped micro porous aeration head cluster, carry, continue the motion that it is similar to fountain form, so circulation endlessly, the liquid circulation campaign of this relative big scale being guided, contributes 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 reactor is to rely on microwave excited electrodeless ultraviolet lamp, the uv-radiation feature 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, region within silica tube periphery approximately 20 cm distance is effective area, and this region is exactly the efficient region of photochemical catalysis oxidative degradation; This case method is to be positioned at the described cluster-shaped micro porous aeration head cluster under silica tube, intensively discharge highdensity ascension bubble flow, it is intensively discharged towards silica tube periphery photochemical catalysis oxidation effective area as fountain, this method contributes to improve the oxygen atmosphere of effective area described in silica tube periphery and supplies with intensity, contributes to accelerating ultraviolet catalyzing oxidizing degrading reaction process.

Based on this case structure, 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, containing ozone-air bubble ascension path sufficiently long, the time sufficiently long contacting with water body containing ozone-air bubble, 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 ozone-air bubble, utilize 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 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 nanometer 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 tackled step by step scheme and can protect secondary filter to make its filtration passage avoid the rigid obstruction of large particulate matter; 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 interception scheme, 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; Address above, 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 be 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 interception scheme matches with the virtual rating of catalyzer market supply, actual kind, merges mutually.

And, due to the interception of this case catalyzer, mechanism is external mechanism, its filter core just needn't be soaked in the strong oxidation of inside reactor, in the liquid of strong uv irradiation, therefore, can needn't consider the tolerance to uv irradiation, strong oxidizing condition completely, like this, selecting of filter core material, just there is no the restriction aspect extraordinary tolerance, can in more vast optional material kind, select, and need not be confined to again the material of more expensive PVDF and so on completely.

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, for tackling step by step catalyst particles, originally the sewage draining exit of commercially available relevant device is used as being held back the recycling delivery port of catalyst particles or refluxing and use delivery port again by conversion in this case.

Above address, based on this case structure, 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, containing ozone-air bubble ascension path sufficiently long, the time sufficiently long contacting with water body containing ozone-air bubble, 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 ozone-air bubble, utilize 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, before speak 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, in this case structure, allow several cubes to dozens of cube even under the processing capacity framework of hundreds of cube volume, above inside reactor liquid level, have in ozone effusion, the DeR that shows inside reactor has reached terminal, and be the whole uniformity of internal liquid reach the terminal of DeR, this terminal point determining factor is that the condition that can provide with this case organization plan matches, this case is at its exhaust port position installing ozone sensor of reactor, in this locations of structures, ozone detected, just mean that 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 providing indication information accurately to operator, 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 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 is organization plan according to this, can know in time the terminal of inside reactor DeR process, and organization plan according to this, when reaction reaches terminal, automatically close the power supply of magnetron and pneumatic pump, stop in time, to inside reactor Implantation Energy, so can avoiding unnecessary energy dissipation, and, this case is structure according to this, 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, its framework of this case has determined that it does not have ozone more than needed can supply discharge.

Among this case structure, the microwave exposure spatial domain of its inside reactor is subject to forcing to cut off, limit, this case and adopt the multistage backwash filter structure of external cascade to tackle subtly catalyst particles, back flush type hollow fiber microfiltration membrane assembly wherein and back flush type polysulfone hollow fiber ultrafiltration membrane system are all external and away from reactor core, microwave can not be irradiated to described membrane module completely, based on this structure of this case, got around described point-like completely and pierced the heat penetration erosion destruction problem of formula, this problem is settled properly thus.

This case reactor inner chamber bottom surface is hollow gradually to central zone by periphery, described hollow its gradient is between 5 degree and 35 degree, and this case ultrasonic transducer is outer side position or the medial surface position that is installed in this its hollow innermost, reactor inner chamber bottom surface corresponding part reactor diapire with attaching, above address, this case structure 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 is that periphery liquid sinks, middle liquid rises, and so constantly moves in circles, above address, under some pH value regulates not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles is easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness, especially for those sections of small particle size relatively among this particle size range, easily occur because of presetting not in place, the incorrect agglomeration traits causing of pH value of pH value especially, the situation of reuniting for this catalyst particles, is immediately to adopt an effective measure, and carries out the depolymerization running for coacervate, at catalyst particles, occur under serious situation of reuniting, some heavier macro aggregates are wherein due to action of gravity, tend to gradually to the sedimentation of reactor intracavity bottom, in this case structure, reactor intracavity bottom is hollow structure, and, this case structure can driving a reaction device internal liquid be made the cyclic motion of described relative big scale, 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 of described hollow structure and sweep to hollow innermost and make them be gathered in there, in this case structure, ultrasonic transducer is positioned at this hollow innermost locations of structures just, this hollow innermost region, it is the final region of assembling of described macro aggregate, also be that ultrasonic wave can be damply minimum simultaneously, closest range ground, the most consumingly, for macro aggregate, carry out depolymerization running region most effectively, this structure of this case can allow with minimum ultrasonic energy loss, realizes maximized ultrasonic depolymerization effect, this case is structure according to this, can converge coacervate sediment, and in the most concentrated region of coacervate sediment, implements depolymerization running, the ultrasonic wave that is derived from reactor bottom certainly simultaneously also can be radiated other region in inside reactor liquid, and those smaller are still being brought into play to unzipping in the coacervate of suspended state, this case associated ultrasonic radiation mechanism is the mechanism that can start as required or close, this case has realized thus for the instant original position of this catalyst particles agglomeration traits and having disposed.

In structure for shielding the silica tube that protects 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 is to be mainly difficult for by the mineral-type impurity that light-catalyzed reaction touched certainly, and the incrustation phenomenon because this mechanism forms is easy to be observed after equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, although be very thin one deck, be also enough to the ultraviolet radiation of electrodeless ultraviolet lamp to cause significantly and stop, this will cause the actual treatment effect of this microwave and photo catalysis reaction treating device significantly to reduce; In this case structure, be positioned at the ultrasonic transducer of reactor bottom, among the depolymerization running of carrying out in the irregular situation of seriously reuniting for accidental catalyst particles, the ultrasonic wave of its radiation, certainly also can arrive silica tube place locations of structures, this ultrasonic wave, when carrying out original position depolymerization running, is also being carried out the ultrasonic clean scale removal work for the long-pending thing of silica tube surface dirt in the lump; And, the installation position of ultrasonic transducer is away from silica tube place locations of structures, decay to some extent when ultrasonic radiation arrives silica tube position, therefore, the suffered ultrasonic impact in silica tube surface is low intensive ultrasonic impact, this leniently scale removal of low intensive ultrasonic impact, can avoid again or significantly weaken its silica tube surface smoothness loss that may cause of ultrasonic cavitation; Based on this structure of this case, can not tear open under the prerequisite of machine, immediately, effectively remove the dirty lamination on this silica tube outer wall, safeguard by this lasting high-level efficiency of this microwave and photo catalysis DeR device.
