Catalyst retains mechanism's physics and assists the photocatalytic waste water degradation reactor removing attachment

Technical field

The present invention relates to a kind of catalyst retain mechanism's physics assist except attachment photocatalytic waste water degradation reactor, belong to C02F technical field of waste water processing.

Background technology

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

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

The disclosure number is the Chinese patent application case of CN102260003A, using microwave as excitaton source, electrodeless ultraviolet lamp is excited to launch ultraviolet, the suspension liquid being mixed with photocatalyst titanium dioxide is irradiated in liquid internal, this electrodeless ultraviolet lamp shroud by silica tube and protect, pneumatic pump is had 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 being 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, the program is also with the membrane separation assemblies that reactor is built-in, carry the water after analysing purification, and realize retaining of photocatalyst titanium dioxide fine particles with this membrane separation assemblies and use again, the program also sets up dividing plate between non-polar ultraviolet light source and membrane separation assemblies, for preventing ultraviolet to the radiation injury of the membrane separation assemblies of organic matter, pass into the air of inside reactor, part participates in the photocatalytic degradation reaction relying 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 also plays the direct oxidative degradation for organic pollutant certainly.

The Chinese patent application case that the disclosure number is CN102260003A certainly serves 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 will talk below us is problem.

The problem below will spoken of, has 14; This ten four problems is ten four problems arranged side by side; The priority of its sequence is only consider easily for discussion.

One of problem:

The disclosure number is the Chinese patent application case of CN102260003A, it is be placed in reactor inner chamber for tackling the membrane separation assemblies of catalyzer titanium dioxide fine particles, be immersed among handling object liquid, and what rely on ascension contains ozone bubbles to wash away membrane separation assemblies, remove its surface by this adsorbed, the catalyst particles be detained, reach the recovery of catalyst particles, recycling object, simultaneously, membrane separation assemblies is also rely on this mode self-cleaning and keep its separating power, so, based on this structure, business curtain hollow fiber film assembly or plate film assembly can only be selected, and, this membrane separation assemblies needs to be immersed in the context of the strong oxidizing property of ozone bubbles ascension, therefore, requirement must be had to the tolerance against oxidative power of membrane separation assemblies, the organic membrane separation assembly of common material can not tolerate such environment for use, therefore the membrane separation assemblies of PVDF material can only be selected, this point clearly illustrates that in open text the 0009th section of word of this case and claim 3, this kind needs its material cost of filter membrane of special tolerance against oxidative power higher, and its commercially available price is certainly also higher than common organic micro-filtration membrane module of non-oxidation durability requirements, in other words, the frame mode of this case, causes the PVDF material that the material of membrane separation assemblies is limited to costly.Have again, UV-light possible in device is revealed, organic membrane assembly may be touched, this organic membrane assembly material also 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 PVDF material costly.

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.

Can so, under the prerequisite using organic material membrane module, bypass this PVDF filter membrane material limitation? this is a problem needing to solve, and this is one of problem.

Problem two:

In view of the scouring force of described ascension bubble, cleaning capacity is more weak, therefore, with this cleaning mode with the use of its aperture of membrane separation assemblies can only select the filter opening aperture of larger micro-filtration rank, the filter opening aperture of this micro-filtration rank is 0.1-0.2 micron, about this point, have in open text the 0009th section of word of this case and claim 3 equally and clearly limit, this kind of filter opening aperture limits, from the type selecting of the such membrane separation assemblies of this case, built-in and soak use-pattern, the self-cleaning method of ascension bubble, be inevitable, its filter opening aperture can only be limited in micro-filtration rank.In other words, this its scouring force of mode, cleaning force of washing away with ascension bubble is too weak, to such an extent as to cannot tackle the filter membrane of more small-bore at all, thus, in this case device, filter sizes 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, the filter opening aperture of 100-200 nanometer that corresponding is exactly; 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 being less than 100 nanometers cannot be blocked; In other words, the catalyst particles being less than 100 nanometers, by directly penetrating, by the filter opening of membrane module, is mixed among so-called water purification that DeR device exports.

Present needs are had a talk the particle diameter of photocatalyst involved by ultraviolet catalytic DeR and photocatalyst dosage form selection.

The professional person being engaged in photocatalytic degradation research knows, reacts, its catalyzer multiselect titanium dioxide fine particles catalyzer with the photochemical degradation of uv light induction, at present, laboratory level is developed the photodegradation particle catalyst based on optically catalytic TiO 2 characteristic various in style, certainly, the photodegradation catalyzer that these different preparation methods are formed, its particle diameter is also various, its particle diameter of photocatalyst that different preparation method makes is little of 20 nanometers, and greatly to 100000 nanometer is also 100 microns, has, 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 is only confined to laboratory level, and does not have to be formed production level commercially available on a large scale, at present known can make a big purchase in large quantities commercially available can actual a large amount of photocatalyst for UV-light wave band used 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 can commercially make a big purchase in large quantities to obtain, and can use in a large number at industrial scale, therefore, also be usually used as with P25 catalyzer reference pointer or the contrast pointer of weighing various self-made photocatalyst catalytic performance in photochemical catalysis specialized laboratory, in fact, in view of the feature of ultraviolet catalytic DeR, the photocatalyst that dispersity is higher, be applicable to the needs of this type reaction, that is, median size is in its catalyst interfacial area that can provide of photocatalyst of 21 ran, anti-settling ability, catalytic performance permanent stability etc. aspect, comprehensive, optimal.Simply, at present, good and cheap, the photocatalyst of the UV-light wave band of the ready-made commercially available commercial grade can actually make a big purchase in large quantities, used is exactly median size is the gas phase titanium dioxide P25 catalyzer of 21 nanometers; At plant-scale application, this median size is the photocatalyst of 21 nanometers is actual first-selections.

Address above, the disclosure number is the Chinese patent application case of CN102260003A, it is for tackling the membrane module of photocatalyst, adsorbed with the stripping film assembly surface that washes away of ascension bubble, the catalyst particles of deposition, but, its scouring force of mode that this kind washes away with ascension bubble, cleaning force is too weak, to such an extent as to the filter membrane of more small-bore cannot be tackled at all, therefore, in this case device, filter sizes is limited at micro-filtration filter opening rank between 0.1 micron-0.2 micron, change a measure unit, in this case device, filter sizes 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, formation secondary pollution, certainly also causes the heavy losses of catalyzer and unrenewable, even if use the titanium dioxide optical catalyst of special Large stone for this reason of other kind, because mutually colliding or colliding with wall in its use procedure, also a large amount of small particle size fragment can must be produced, wherein particle diameter is less than the fragment of 100 nanometers, equally can not tackle by the micro-filtration filter opening between 100 nanometer-200 nanometers, these small shredss also can enter among so-called water purification through its membrane module, form secondary pollution.

Visible, the disclosure number is the Chinese patent application case of CN102260003A, its for the interception structure scheme of photocatalyst particulate and the cleaning solution of related film assembly all undesirable.

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

Problem three:

We know, liquid water body itself also can absorb the energy of microwave, and cause itself temperature-rise effect of the liquid water body that is processed, and this temperature-rise effect occurred with wastewater treatment process, 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 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 causes unnecessary microwave energy and wastes, in view of the apparatus structure scheme that the above-mentioned publication number Chinese patent application case that is CN102260003A is shown, its rational approach, can only be reduce single tank process capacity in other words by the volume of minimizing microwave and photo catalysis reactor to reach the object weakening the unnecessary dissipation of microwave, about this point, the clear suitable size that have expressed about this apparatus structure entirety in this its embodiment of CN102260003A application case, what the preferred size expressed by it was corresponding is exactly the very little device of a profile, 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, correspond ground, the wastewater treatment capacity of single tank is therefore also little, more particularly, the internal capacity corresponding to device suitable size expressed in embodiment is 40 liters, also namely 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 solve only the trade effluent of 0.04 cube, so, just need the repetition operated to the complete set of tail by head carried out many times, the cumulative of its treatment capacity just has plant-scale meaning, so to say, just individual analogy roughly, the wastewater treatment capacity that roughly corresponding 0.04 cube, the single tank of its preferred structure size of this case is such, need repetition 1000 times by head to the complete set of 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, the wastewater degradation processing efficiency of its reality of scheme that this kind is shown by CN102260003A may not be fully up to expectations.Therefore, how under not causing more microwave energies to waste or reducing the prerequisite of microwave energy waste, increase single tank wastewater treatment capacity, reduce this intermittent type wastewater treatment equipment unnecessary too many by head to the repetitive operation number of times of tail, improving its waste water treatment efficiency, is a significant technical problem merited attention.

On the other hand, according to the literature, some system, when the direct irradiation wastewater liquid of microwave, photochemical catalysis degradation efficiency truly has raising, that is, in some system, between the direct irradiation wastewater liquid of microwave and photochemical catalysis are degraded, there is certain coupling.

Therefore, how under the prerequisite taking into account described coupling, improve the processing efficiency of wastewater degradation device, be worth inquiring into, this is problem three.

Problem four:

The scheme that this kind is 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, in fact corresponding small size, the low capacity device of CN102260003A scheme as expression clear in its embodiment, the impact that almost has nothing observable.From plant-scale application demand, undersized the device of divergence process amount can 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 cyclic motion of the relative big scale of retort internal liquid will highlight naturally; Imagine 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, be exactly a problem certainly, this is problem four.

Problem five:

For the photochemical catalysis oxidizing reaction of 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 organic concentration in oxidized object and water body, oxidation complexity that organic molecule structure determines himself etc., it four is sufficient degree of oxygen atmosphere, when other condition is identical, the sufficient degree of oxygen atmosphere, the key element that of affecting photochemical catalysis oxidative degradation ability is very important will be become.

As CN102260003A the scheme of showing, its numerous micro porous aeration head disperseds being placed in reactor inner chamber bottom are in bottom, and by the water distribution board alleged by it, the effect of this micro porous aeration head dispersed arrangement is made to 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 the one side that it is favourable, but, from another side, the mode that this micro porous aeration head dispersed arranges, the supply of oxygen atmosphere too disperses, and what in fact need most the region of enhanced oxygen blowing is the most effective area of photochemical catalysis oxidation, because the Effective depth penetration of short wave ultraviolet in liquid water body only has 20 cm, therefore, need most enhanced oxygen blowing to promote that in fact the effective area of photochemical catalysis oxidation course is exactly the region within silica tube periphery about 20 cm distance, in other words, region within silica tube periphery about 20 cm distance really needs enriched with oxygen atmosphere to supply the region ensured, this region oxygen atmosphere supply is stronger, oxidizing reaction is also just carried out faster, especially especially, electrodeless ultraviolet emission is produced in microwave excitation mode, its feature can accomplish high-power, high strength exactly, this is the strong point of this lamp-type of electrodeless ultraviolet lamp, but, just because of the superpower of its uv-radiation, high strength, mate with powerful oxygen atmosphere supply capacity with regard to more needing, otherwise, that powerful uv-radiation ability is really just that major part has been wasted.Address above, as CN102260003A the scheme of showing, factors limits its reactor size, limit its actual treatment capacity, what clearly illustrate that in its specific embodiment is such, that can only be the little reactor that a single tank single treatment amount only has about 40 liters, at so little reactor, when little inner chamber, because size is inherently very little, so, it is oxidized the shortcoming in effective area oxygen supply concentration degree in photochemical catalysis, would not be so obvious, even negligible, a not Problems existing can be regarded more even completely as, in the face of such undersized little reactor, shortcoming problem in oxygen supply concentration degree, not mind may be floated, but, imagine, if described many limiting factors can be overcome, if way actual implementation one can be had 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 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 problem five.

Problem six:

This CN102260003A scheme pump air into include electrodeless ultraviolet lamp silica tube within, reach the aeration-cooling of electrodeless ultraviolet lamp, the object of cooling, and those flow over the air of silica tube, because being subject to ultraviolet irradiation, some air can change ozone into, therefore, the air flowed out from silica tube is exactly the air containing some ozone certainly, this is transferred to containing ozone-air and is positioned at micro porous aeration head below reactor by the program, and disengage from micro porous aeration head, at these containing in ozone bubbles ascension process from bottom to top, wherein contained ozone can meet with the organic molecule that runs among distance and redox reaction occurs, this redox reaction can consume a part of ozone certainly, this be do not have doubt, but, address above, as CN102260003A the scheme of showing, the many factors that cannot ignore certainly existed limit its reactor size, limit its actual treatment capacity, what clearly illustrate that in its specific embodiment is such, that can only be the little reactor that a single tank single treatment amount only has about 40 liters, at so little reactor, when little inner chamber, because overall dimension is inherently very little, so, it also can only be a very little size that the longitudinal size of its reactor inner chamber or regard as with reckoning in every item contains the liquid degree of depth, this size as among its embodiment clearly illustrate that, 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 analyze with the Sheng liquid degree of depth of 40 centimetres, so, does is this Sheng liquid degree of depth of 40 centimetres what concept? that is to say, short 40 centimetres are only had by the path of waste water containing ozone-air ascension, this path is too short, pass through at a gallop containing ozone-air bubble and only only have 40 centimetres of dark water bodys, too short for duration of contact with water body, ozone contained in bubble, a very little part can only be had to be used to oxidative degradation organism, and most ozone in fact just passes by liquid simply, from liquid level effusion and emptying through exhaust port, briefly, the oxygenizement potentiality major part of these ozone has been wasted, and, effusion, in fact the ozone be wasted can cause unnecessary atmospheric pollution, this case main inventive people once squeezed into containing ozone-air via micro porous aeration head with normal domestic use ozone machine in one meter of dark tank, when the depth of water degree of depth reaches one meter, still near the water surface, obviously can smell the smell of ozone, visible, that 40 centimetres of dark Sheng liquid degree of depth are obviously be not enough to utilize ozone completely, 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 are more it is contemplated that ozone utilizes more completely, contaminative exhaust emissions is less without extreme ultraviolet wastewater degradation reactor, and this is problem six.

Problem seven:

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, prematurely immediately stop continuing Implantation Energy to inside reactor only lately; If stop the moment of Implantation Energy too early, then wastewater degradation is incomplete; And if reach reaction end already, 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 to the wastewater degradation terminal moment, so, just can only estimate by experience the terminal that wastewater degradation reacts; And estimate by experience the terminal that wastewater degradation reacts, that obviously can not be satisfactory; So, how to make neither also undelayed instant information output in advance for the wastewater degradation reaction end moment, and immediately close the energy input to reactor in the just right moment, a technical threshold that can not despise exactly, this is problem seven.

Problem eight:

Accept the described trade effluent of microwave and photo catalysis degradation treatment, wherein be mingled with the material that some originate from the metal particle and carbon granules and so on of mechanical system abrasion process unavoidably, even if quantity is small, its existence is almost 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 microwave and photo catalysis reaction zone, being installed in wherein does 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 the installation area of organic membrane separation assemblies institute described in the program, based on the working mechanism of membrane separation assemblies, the particulate of metal particle as above and carbon granules and so on its be difficult to avoid in the accumulation process on the organic top layer of membrane separation assemblies, 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, absorb the particulate of the described metal particle and carbon granules and so on of the accumulation state of microwave energy, nature can to the top layer of the organic membrane separation assemblies that it is close to produce based on heat penetration erosion mechanism continue pierce destruction, as mentioned above, because the structures shape of this its device of CN102260003A application case can only select polyvinylidene fluoride film material, this polyvinylidene fluoride film material heatproof about 140 degrees Celsius, really higher than general film material heatproof many, but, the heat penetration erosion effect that its point-like of particulate absorbing the described metal particle and carbon granules and so on of the accumulation state of microwave energy pierces 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 this its device of 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, determine under this structural framing, the heat penetration erosion destruction problem that above-mentioned point-like pierces formula cannot be avoided, therefore, how to get around the heat penetration erosion destruction problem that this point-like pierces formula, also need to consider, this is problem eight.

Problem nine:

The disclosure number is the Chinese patent application case of CN102260003A, open text text the 0008th section of word of its specification sheets and claim Section 2, for the catalyst particle size scope that its device can be suitable for, have 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 the section of the relatively small particle size of those among this particle size range, easily occur especially because of pH value presetting not in place, pH value is incorrect and the agglomeration traits that causes; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, the depolymerization carried out for coacervate operates; But we are among this CN102260003A scheme, do not see any structure contributing to immediately dissolving this problem or can immediately dissolve this problem scheme prompting.Can only be the reactor of small scale structures just like that because factors restriction for such as CN102260003A scheme, still manually directly can mention reactor, carry out toppling over and inspect in reactor outside, process above-mentioned reunion situation, so, if likely expand its capacity, just so to say, if be the several cubes of large-scale reactors to dozens of cube or huge reactor, that is not obviously topple over it by hand to operate the problem that can tackle, so, for the situation that this catalyst particles is reunited mutually, how to realize instant original position to dispose, it is exactly a technical problem, this is problem nine.

Problem ten:

In the apparatus structure of the disclosure number expressed by the Chinese patent application case of CN102260003A, for shielding the silica tube protecting electrodeless ultraviolet lamp, its outer wall, refer to the outer wall of silica tube, through for a long time with the contact of processed trade effluent, unavoidably incrustation gradually, the long-pending material of dirt certainly mainly not easily the mineral-type impurity that touches by light-catalyzed reaction, because of the incrustation phenomenon that this mechanism is formed, be easy to be observed after equipment long-play; Be attached to the dirty lamination of described silica tube outer wall, although just very thin one deck, be also enough to cause significant stop to the ultraviolet radiation of electrodeless ultraviolet lamp, this significantly reduces causing the actual treatment effect of this microwave and photo catalysis reaction treating device; The bubble of dispersed ascension in its reactor is because too disperseing, wash away strength more weak, if only rely on this bubble comparing dispersion to maintain the bright and clean of silica tube surface, really undertake to do what is apparently beyond one's ability, in other words, this compares the bubble of dispersion, and what it was more 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 fouling problem is subtle, but on industrial application yardstick, this fouling 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 problem ten.

11 of problem:

This problem for address above nine of problem its problem that derives.Speak of above, 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; The section of those the relatively small particle size among its suitable catalyst particle size range of especially this CN102260003A scheme being touched upon, easily occur especially because of pH value presetting not in place, pH value is incorrect and the agglomeration traits that causes; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, the depolymerization carried out for coacervate operates; Based on this its framework of CN102260003A scheme, operator cannot perceive the situation that described reunion occurs inside reactor immediately, thus also cannot make instant disposal, thus, can only should be that its limited usefulness of reactor of small scale structures can reduce further by factors restriction; Therefore, among the application running of reactor, particularly, for example, among the application running of possible large-scale reactor or huge reactor, the how immediately awareness inside reactor catalyst particles main inducing parameter of reuniting, be a key issue, this is 11 of problem.

12 of problem:

Based on this its framework of CN102260003A scheme, due to the restriction of factors addressed, its reactor can only be the smaller reactor of undersized treatment capacity, the useful size of reactor inner chamber is certainly also smaller, can be used among its structure of reactor inner chamber settling the spatial altitude of curtain type film assembly approximately also just at 30 cm, so, even if just adopt the curtain type film assembly of very small breadth, also almost plug can only be headed on inside reactor in two up and down, due to the little treatment capacity of reactor, small size, so, after its DeR completes, under the situation getting rid of liquid from inside to outside, its curtain type film assembly exposes in atmosphere unavoidably, although each time exposed can not length, but, the accumulation result often bought and sold, this curtain type film assembly is made to contact with air too much exactly, its normal service requirements of curtain type film assembly, will use under complete submerged state, that is, must be that hygrometric state uses, if curtain type film assembly contacts with air too much, it can be made more aging than more quickly, Performance comparision is decayed rapidly, 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 protecting the membrane module for tackling catalyzer, can use in normal conditions, the too much contact with air can be avoided, to safeguard its normal usage energy, guarantee its normal service life, the problem faced of needs exactly, this is 12 of problem.

13 of problem:

Based on this its framework of CN102260003A scheme, among its running, by the granules of catalyst that curtain type film assembly is tackled, a part is at curtain type film assembly surface deposition, and another part is then trapped among liquid object phase, and in causing liquid object mutually thus, granules of catalyst concentration progressively raises along with the progressively reduction of liquid phase volume, this is for follow-up membrane sepn, its membrane sepn load also can raise thereupon gradually, and the problem that before and after this membrane sepn load, difference is excessive needs to solve, and this is 13 of problem.

14 of problem:

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

Advantage of the present invention is, coordinating wire netting described in two panels electrodeless ultraviolet lamp and screen thereof to be protected with the cylindrical member of metal material shrouds in it with silica tube, this structure retrains the effect spatial domain of microwave simultaneously, so, spatial domain around silica tube outer wall and described cylindrical space between border defines a microwave excitation and assists and the synergistic wastewater degradation conversion zone of photochemical catalysis, and, the multiple hole of wire netting described in two panels or the structure of many meshes, do not affect waste water and bubbling and on containing ozone-air bubble flow freely into and out of this spatial domain; And the spatial domain around described cylindrical space between border and described container inner wall, be the weak irradiation spatial domain of microwave zero irradiation spatial domain or microwave, the simple pyrogenicity of waste water water body to microwave absorbs to be contained, significantly weakens the unhelpful dissipation of microwave energy thus; By significantly expanding the design volume in this microwave zero irradiation spatial domain or the weak irradiation spatial domain of microwave, the significantly expansion of single tank reactor volume can be realized, allow 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.

Based on the structure of this case, design volume and single tank wastewater treatment capacity of reactor can be expanded to several cubes to dozens of cube; Based on this structure of this case, the frequency of a complete set, substantial length of operation can be reduced significantly, be conducive to the saving of human and material resources.

Its existence of described cylindrical member in this case apparatus structure, and the liquid stream of described internal tank can be guided to rise fast along the internal passages of this cylindrical member, and by microwave excitation auxiliary with photochemical catalytic oxidation concerted reaction region after, spread to surrounding by top area, sink via neighboring area, arrive described container intracavity bottom section, then converge to the internal passages of this cylindrical member through the hydraucone of cylindrical member, continue its circulation; Certainly, by pack ascension bubble flow pull the major impetus that strength is this circulation; The liquid circulation campaign of this relative big scale guided, contributes to the homogenizing guaranteeing inside reactor liquid degradation reaction process, and this, for this case large-scale DeR device so, is necessary.

Its UV source of this case reactor relies on microwave excited electrodeless ultraviolet lamp, the uv-radiation feature of this lamp-type can accomplish high-power, high strength exactly, but the Effective depth penetration of ultraviolet in liquid water body only has an appointment 20 centimetres, therefore, region within silica tube periphery about 20 cm distance is effective area, and this region is exactly the efficient region of photochemical catalysis oxidative degradation; This case device is with described cylindrical member, pack is from the bubble flow of numerous micro porous aeration head, make it intensively towards silica tube periphery photochemical catalysis oxidation effective area release, this mode contributes to the oxygen atmosphere supply intensity improving effective area described in silica tube periphery, 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, describedly significantly to expand, that design volume by significantly expanding microwave zero irradiation zone or the weak irradiation zone of microwave realizes, 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, such as, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., when containing the liquid degree of depth and being enough dark, containing ozone-air bubble ascension path sufficiently long, the time sufficiently long contacted with water body is steeped containing ozone-air, just can with abundant reducing substances fortune in its ascension process, and thoroughly or be close to and exhaust ozone contained in bubble up hill and dale, thus, incomplete problem is utilized to be solved containing ozone composition oxidation potential in ozone-air bubble, and, because long ascension path causes ozone depletion, the ozone that can cause environmental pollution would not be entrained with again in reactor tail gas.

This case with external multistage filter, reach the interception step by step counting the collision fragment of the small scale of nanometers from coacervate macrobead to ten to catalyst particles, be close to reclaim up hill and dale, reuse photocatalyst, be close to and take precautions against catalyst loss and the secondary pollution that causes up hill and dale; This is interception structure secondary filter can be protected to make its filtration passage from 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 interception structure, can fully tackle nano level photocatalyst, and it can be close to certainly tackles the catalyzer that this median size of gas phase titanium dioxide P25 is 21 nanometers up hill and dale; 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 fact pay the utmost attention to the photocatalyst selected in industrial scale applications; This case catalyzer interception structure matches with the virtual rating of catalyzer market supply, actual kind, merges mutually.

And, this case catalyzer interception mechanism is external, its filter core need not be soaked in the liquid of the Strong oxdiative of inside reactor, strong uv irradiation, therefore, can need not consider the tolerance to uv irradiation, Strong oxdiative condition completely, like this, select just without the restriction in extraordinary tolerance in filter core material, can select in more vast optional material kind, and the material of PVDF costly and so on need not be confined to completely again.

Involved 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 case uses this kind of back flush type to equip, be used to tackle catalyst particles step by step, originally the sewage draining exit of commercially available equipment, is used delivery port again by recycling delivery port or backflow that conversion is used as by retaining catalyst particles in the present case.

Address above, based on this case structure, the capacity of reactor or treatment capacity can significantly be expanded, describedly significantly to expand, that design volume by significantly expanding microwave zero irradiation zone or the weak irradiation zone of microwave realizes, 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, such as, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., when containing the liquid degree of depth and being enough dark, containing ozone-air bubble ascension path sufficiently long, the time sufficiently long contacted with water body is steeped containing ozone-air, just can with abundant reducing substances fortune in its ascension process, and thoroughly or be close to and exhaust ozone contained in bubble up hill and dale, thus, incomplete problem is utilized to be solved containing ozone composition oxidation potential in ozone-air bubble, and, because long ascension path causes ozone depletion, the ozone that can cause environmental pollution would not be entrained with again in reactor tail gas, only when being subject to processing when in water body, reducing substances and organic pollutant are degraded totally, again without can for the organic pollutant of ozone oxidation reaction in water body, those unnecessary ozone just likely no longer consume and to overflow liquid level through long ascension path, speak of above, one among the some problem that this case solves simultaneously, it is the circulation of the relative big scale of enhanced reactor internal liquid, systemic circulation that this enhances mechanism facilitates the uniformity of inside reactor liquid organic pollutants DeR process contained by it, thus, several cubes that allow in this case structure under the process capacity framework of dozens of cube even hundreds of cube volume, when inside reactor ullage has ozone to overflow, namely show that the DeR of inside reactor reaches terminal, and be the overall uniformity of internal liquid reach the terminal of DeR, this terminal point determining factor is the matching criteria that can provide with this case organization plan, this case is at its exhaust port position of reactor installing ozone sensor, ozone is detected in this locations of structures, just mean that inside reactor DeR is reached 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 by ozone sensor export electric signal send power-supply controller of electric to by cable, this power-supply controller of electric is also connected with magnetron and pneumatic pump respectively by cable, the described electric signal of power-supply controller of electric received by it carries out power switch action, certainly, its function mode is, receive the signal of the ozone effusion that ozone sensor sends at power-supply controller of electric when, the power supply of magnetron and pneumatic pump is led in automatic closedown, this case is organization plan according to this, can know the terminal of inside reactor DeR process in time, and organization plan according to this, when reaction reaches terminal, automatically close the power supply of magnetron and pneumatic pump, stop to inside reactor Implantation Energy in time, so can avoid unnecessary energy dissipation, and, this case is structure according to this, when DeR is reached home, the power supply of described magnetron and pneumatic pump can be closed in time, this power-off action is synchronous, the same generation process terminating in a flash ozone also, because ozone generation process is stopped in time, a large amount of ozone exceeding needs would not be had to disengage from described exhaust port, thus avoid unnecessary secondary pollution or say secondary pollution, its framework of this case determines the ozone that it does not have more than needed can for 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 external cascading multiple stages backwash filter structure to tackle catalyst particles subtly, back flush type hollow fiber microfiltration membrane assembly wherein and back flush type polysulfone hollow fiber ultrafiltration membrane system 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 the heat penetration erosion destruction problem that described point-like pierces formula completely, this problem is settled properly thus.
