Technical field

The present invention relates to a kind of photochemical catalysis wastewater degradation reactor expansion method that the anti-gushing water in lamp district is safeguarded of taking into account, belong to the C02F technical field of waste water processing.

Background technology

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

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

the disclosure number is the Chinese patent application case of CN102260003A, to use microwave as excitaton source, excite electrodeless ultraviolet lamp emission ultraviolet ray, be mixed with the suspension of photocatalyst titanium dioxide in the liquid internal irradiation, 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 that is overflowed by quartz cavity is via pipeline and the micro porous aeration head UNICOM that is positioned at reactor bottom, the lower zone of this inside reactor is aeration zone, the upper area of this inside reactor is the microwave and photo catalysis reaction zone, this scheme is also with the built-in membrane separation assemblies of reactor, carry the water of analysing after purification, and with this membrane separation assemblies, realize that holding back again of photocatalyst titanium dioxide fine particles use, this scheme is also set up dividing plate between non-polar ultraviolet light source and membrane separation assemblies, be used for preventing the radiation injury of ultraviolet ray to the membrane separation assemblies of organic matter, pass into the air of inside reactor, part is participated in the photocatalytic degradation reaction that relies on photocatalyst titanium dioxide directly, some air, under the direct irradiation of UV-light, generate a certain amount of ozone, the ozone of this generation is also being brought into play the direct oxidative degradation for organic pollutant certainly.

The disclosure is number for the Chinese patent application case of CN102260003A has certainly played very important pushing effect for the progress of microwave and photo catalysis wastewater degradation technology, and the work that its research staff launches in this field is admirable.

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

The problem that below will speak of, have 16; These 16 problems are 16 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, its membrane separation assemblies that is used for interception catalyzer titanium dioxide fine particles is to be placed in the reactor inner chamber, be immersed in and process among object liquid, and rely on the ozone bubbles that contains of ascension to wash away membrane separation assemblies, removing by this its surface adsorbs, the catalyst particles that is detained, reach the recovery of catalyst particles, the recycling purpose, simultaneously, membrane separation assemblies is also to rely on this mode self-cleaning and keep its separating power, so, based on this structure, can only select business curtain formula hollow fiber film assembly or plate film assembly, and, this membrane separation assemblies is need to be immersed in the context of strong oxidizing property of ozone bubbles ascension, therefore, tolerance against oxidative power to membrane separation assemblies must have requirement, the organic membrane separation assembly of common material can not tolerate such environment for use, therefore can only select the membrane separation assemblies of PVDF material, this point clearly illustrates that in open the 0009th section word of text of this case and claim 3, its material cost of the filter membrane of the tolerance against oxidative power that this kind needs are special is higher, common organic micro-filtration membrane module that its commercially available price also requires higher than the non-oxidation tolerance certainly, in other words, the frame mode of this case, cause the material of membrane separation assemblies to be limited to more expensive PVDF material.Have again, UV-light possible in device is revealed, may touch the organic membrane assembly, this also the organic membrane assembly material in claimed apparatus can resist ultraviolet light irradiation, from this point, based on the organization plan of this device, the material of organic membrane separation assembly also can only be limited in more expensive PVDF material.

The organic membrane assembly, compared to the ceramic filter assemblies, has its apparent advantage; About this point,, for the personage of filtering technique specialty, be known, here do not launch to repeat.

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

Two of problem:

scouring force in view of described ascension bubble, cleaning capacity is more weak, therefore, 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 the 0.1-0.2 micron, about this point, have clearly and limit in open the 0009th section word of text of this case and claim 3 equally, this kind filter opening aperture limits, type selecting from the such membrane separation assemblies of this case, built-in and soak use-pattern, the self-cleaning method of ascension bubble, be inevitable, can only limit its filter opening aperture in the micro-filtration rank.In other words, this its scouring force of mode that washes away with the ascension bubble, cleaning power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, thus, in this case device, the filter membrane aperture is limited between 0.1 micron-0.2 micron, is the inevitable choice of not discussing leeway.

The filter opening aperture of so-called 0.1-0.2 micron, if change a measure unit, corresponding is exactly the filter opening aperture of 100-200 nanometer; Is what concept that? with 100 nanometer filter opening apertures of its lower limit, its size of catalyst particles that it can be tackled must be more than 100 nanometers, and less than the catalyst particles of 100 nanometers, can't be blocked; In other words, less than the catalyst particles of 100 nanometers will directly penetrate, by the filter opening of membrane module, sneak among the so-called water purification that the DeR device exports.

Particle diameter and the photocatalyst dosage form selection of the related photocatalyst of the ultraviolet catalytic DeR of need to having a talk now.

the professional person who is engaged in photocatalytic degradation research knows, with the photochemical degradation reaction of uv light induction, its catalyzer multiselect titanium dioxide fine particles catalyzer, at present, developed the particle catalyst of the photodegradation based on the optically catalytic TiO 2 characteristic various in style on laboratory level, certainly, the photodegradation catalyzer that these different preparation methods form, its particle diameter is also various, its particle diameter of photocatalyst that different preparation methods make is little of 20 nanometers, and greatly to 100000 nanometer also is 100 microns, has, and wherein is no lack of the photocatalyst kind of excellent performance, but due to the restriction of the evaluation of performance permanent stability, preparation cost and the market expansion etc. aspect factor, most its deliverabilities of described photocatalyst only are confined to laboratory level, and there is no to form extensive commercially available production level, the at present known commercially available photocatalysts that are used for the UV-light wave band that can actually use in a large number that can make a big purchase in large quantities be famous gas phase titanium dioxide P25, its concrete art-recognized meanings of gas phase titanium dioxide P25, the insider knows, does not here launch to repeat, the median size of gas phase titanium dioxide P25 is 21 nanometers, gas phase titanium dioxide P25 performance is not very optimum, but, its stable performance, key is to make a big purchase in large quantities and to obtain on market, and can use in a large number on technical scale, therefore, in photochemical catalysis specialized laboratory also usually with the P25 catalyzer be used as weighing various self-made photocatalyst catalytic performances with reference to pointer or contrast pointer, in fact, characteristics in view of the ultraviolet catalytic DeR, the photocatalyst that dispersity is higher, the needs that are fit to this type reaction, that is to say, median size is in its catalyst interfacial area that can provide of photocatalyst of 21 nanometer left and right, the anti-settling ability, catalytic performance permanent stability etc. aspect, comprehensive, optimal.Say simply, at present, good and cheap, the photocatalyst of the UV-light wave band of the ready-made commercially available commercial grade that can actually make a big purchase in large quantities, use, be exactly median size be the gas phase titanium dioxide P25 catalyzer of 21 nanometers; At plant-scale application, this median size is that the photocatalyst of 21 nanometers is actual first-selections.

above address, the disclosure number is the Chinese patent application case of CN102260003A, it is used for the membrane module of interception photocatalyst, that the stripping film assembly surface that washes away with the ascension bubble is adsorbed, the catalyst particles of deposition, yet, its scouring force of mode that this kind washes away with the ascension bubble, cleaning power too a little less than, to such an extent as to can't tackle the more filter membrane of small-bore at all, therefore, in this case device, the filter membrane aperture is limited at micro-filtration filter opening rank between 0.1 micron-0.2 micron, change a measure unit, in this case device, the filter membrane aperture is limited at the micro-filtration filter opening rank between 100 nanometers-200 nanometer, this is the inevitable choice of not discussing leeway, this case can't tackle without the micro-filtration filter opening between selectable 100 nanometers-200 nanometer the gas phase titanium dioxide P25 particle that median size as above is 21 nanometers certainly, so, if use the P25 photocatalyst, this catalyzer will can't be tackled fully, and flows in so-called water purification, forms secondary pollution, certain heavy losses that also cause catalyzer and unrenewable, even if use other kind for this reason and the titanium dioxide optical catalyst of special large particle diameter, collide or with wall, collide because of mutual in its use procedure, must also can produce a large amount of small particle size fragments, wherein particle diameter is less than the fragment of 100 nanometers, can not be tackled by the micro-filtration filter opening between 100 nanometers-200 nanometer equally, these small shredss also can see through its membrane module and enter among so-called water purification, form secondary pollution.

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

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

Three of problem:

we know, liquid water body itself also can absorb the energy of microwave, and cause itself temperature-rise effect of processed liquid water body, and this temperature-rise effect of following wastewater treatment process and occurring, it not but the situation that we expect, in other words, microwave energy from magnetron is not used to excite electrodeless ultraviolet lamp fully, and have quite a few only to be used 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 single tank processing capacity by the volume that reduces the microwave and photo catalysis reactor to reach the purpose that weakens the unnecessary dissipation of microwave, about this point, clear suitable size of having expressed about this apparatus structure integral body in this its embodiment of CN102260003A application case, what its expressed preferred size was corresponding is exactly a device that profile is very little, so, thus, the distance of reactor wall and microwave radiation source is little, the wastewater flow rate that contacts with microwave is little, the microwave energy that waste water absorbs is relatively also little, with it accordingly, the wastewater treatment capacity of single tank is therefore also little, more particularly, the corresponding internal capacity of device suitable size expressed in embodiment is 40 liters, be also that single tank wastewater treatment capacity is 40 liters, namely 0.04 cube, in other words, it is once a complete set of, substantial length of operation has only solved the trade effluent of 0.04 cube, so, just need to carry out many times by the repetition of head to the operation of the complete set of tail, its treatment capacity cumulative just has plant-scale meaning, so to say, just individual analogy roughly, its preferred structure size of this case is 0.04 cube of such wastewater treatment capacity of single tank of correspondence roughly, need to repeat 1000 times by the complete set of head to tail, substantial length of operation, its accumulation amount, just can reach 40 cubes such one have industrial level wastewater treatment capacity, so excessively loaded down with trivial details repetitive operation will cause manpower, the serious waste of material resources, as seen, its actual wastewater degradation processing efficiency of scheme that this kind showed by CN102260003A may not be fully up to expectations.Therefore, how not cause more microwave energy wastes or to reduce under the prerequisite of microwave energy waste, increase single tank wastewater treatment capacity, reduce the unnecessary too many by the repetitive operation number of times of head to tail of this intermittent type wastewater treatment equipment, improve its waste water treatment efficiency, be a significant technical problem that merits attention, this is three of problem.

Four of problem:

The scheme that this kind showed by CN102260003A, the bubble of the inner dispersed ascension of its retort,, for the cyclic motion of the relative big scale of driving a reaction tank internal liquid, contribute slightly inadequate; Certainly, this weak point, in fact corresponding small size, the low capacity device of clear expression in CN102260003A scheme such as its embodiment, the impact that almost has nothing observable.From plant-scale application demand, undersized device that can not the divergence process amount does not have great magnetism certainly; So, as a kind of possibility, if there is certain mode can realize the significantly expansion for the treatment of capacity, under this situation, its importance of the cyclic motion of the relative big scale of retort internal liquid will highlight naturally; Imagining the possibility that this treatment capacity is significantly expanded, so, how to strengthen the cyclic motion of the relative big scale of retort internal liquid, is exactly an individual problem certainly, and this is four of problem.

Five of problem:

photochemical catalysis oxidizing reaction for the UV-light wave band, there is following so several key element can have influence on the efficiency of this kinds of oxidation reaction, first ultraviolet wavelength, intensity, it two is particle diameters of photocatalyst, the usage quantity of photocatalyst in the unit volume reaction solution, himself catalytic performance etc. of photocatalyst, it three is that oxidized object is organic concentration in water body, oxidation complexity that the organic molecule structure determines himself etc., it four is sufficient degree of oxygen atmosphere, in the situation that other condition is identical, the sufficient degree of oxygen atmosphere, will become a very important key element that affects photochemical catalysis oxidative degradation ability.

the scheme of showing as CN102260003A, its numerous micro porous aeration head disperseds that are placed in reactor inner chamber bottom are in bottom, and by its alleged water distribution board, make the effect of this micro porous aeration head dispersed arrangement become more very, certainly, this is for the situation of the oarse-grained micron-sized photocatalyst that uses relatively easy sedimentation, really there is its favourable one side, but, from another side, the mode that this micro porous aeration head dispersed arranges, the supply of oxygen atmosphere too disperses, and in fact need most enhanced oxygen blowing zone be the effective area of photochemical catalysis oxidation, because the Effective depth penetration of short wave ultraviolet in liquid water body only has 20 centimetres of left and right, therefore, needing most enhanced oxygen blowing in fact is exactly zone within peripheral approximately 20 cm distance of silica tube with the effective area that promotes photochemical catalysis oxidation process, in other words, zone within peripheral approximately 20 cm distance of silica tube is really to need enriched with oxygen atmosphere to supply with the zone that ensures, this regional oxygen atmosphere is supplied with stronger, oxidizing reaction is also just carried out sooner, especially especially, produce electrodeless ultraviolet emission in the microwave excitation mode, its characteristics can be accomplished high-power, high strength exactly, this is the strong point of this lamp type of electrodeless ultraviolet lamp, yet, just because of the superpower of its uv-radiation, high strength just more need to mate with powerful oxygen atmosphere supply capacity, otherwise, that powerful uv-radiation ability is really just that major part has been wasted.above address, the scheme of showing as CN102260003A, factors has limited its reactor size, limited its actual treatment capacity, just as clearly illustrating 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 can ignore, can regard a non-existent problem at all more even fully as, in the face of such undersized little reactor, shortcoming problem about oxygen supply concentration degree aspect, not may float mind, but, imagine, if can overcome described many limiting factors, if can there be one of way actual implementation large-scale, the reactor of high throughput, within so above-mentioned silica tube periphery 20 cm distance, effective area oxygen supply reinforcement 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 reinforcement problem is not allowed to despise more, therefore, how among the structure of possible large-scale photo-catalytical oxidation DeR device, strengthen the oxygen supply concentration degree of described effective area, improve the usefulness of wastewater degradation equipment, the problem that individual exactly needs are kept a close watch on, this is five of problem.

Six of problem:

within this CN102260003A scheme pumps air into the silica tube that includes electrodeless ultraviolet lamp, reach the aeration-cooling of electrodeless ultraviolet lamp, cooling purpose, and those flow through the air of silica tube, because being subjected to ultraviolet irradiation, some air can change ozone into, therefore, the air that flows out from silica tube is exactly the air that contains some ozone certainly, this scheme contains ozone-air with this and is transferred to and is positioned at reactor below micro porous aeration head, and from micro porous aeration head, disengage, contain in ozone bubbles ascension process from bottom to top at these, wherein contained ozone can meet with and occur redox reaction with the organic molecule that runs among distance, this redox reaction can consume a part of ozone certainly, this be do not have doubt, but, above address, the scheme of showing as CN102260003A, the many effects limit that can't ignore that certainly exist its reactor size, limited its actual treatment capacity, just as clearly illustrating 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 illustrating that among its embodiment, only have about 40 centimetres, the Sheng that the reckons in every item liquid degree of depth also just only has 40 centimetres, in fact contain the liquid degree of depth and certainly be less than this number, just with the Sheng liquid degree of depth of 40 centimetres, analyze, so, is this Sheng liquid degree of depth of 40 centimetres what concept? that is to say, contain the ozone-air ascension and only have short 40 centimetres by the path of waste water, this path is too short, containing the ozone-air bubble passes through at a gallop and only only has 40 centimetres of dark water bodys, too short duration of contact with water body, contained ozone in bubble, can only there is a very little part to be used to the oxidative degradation organism, and most ozone is in fact just passed by liquid simply, from liquid level effusion and emptying through exhaust port, briefly, the oxygenizement potentiality major part of these ozone has been wasted, and, overflow, in fact the ozone that is wasted can cause unnecessary atmospheric pollution, the main contriver of this case once contained ozone-air via micro porous aeration head to squeezing in one meter dark tank with the normal domestic use ozone machine, in the situation that the depth of water degree of depth reaches one meter, still can obviously smell the smell of ozone near the water surface, as seen, the sort of 40 centimetres of dark Sheng liquid degree of depth are obviously to be not enough to utilize fully ozone, as seen, 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 is that the ozone utilization is more complete, the contaminative exhaust emissions still less without extreme ultraviolet wastewater degradation reactor, this is six of problem.

Seven of problem:

Its running of waste water catalytic degradation reaction device, require the expenditure of energy, and therefore, operator are bound to wish, when the wastewater degradation reaction proceeds to terminal, can impartially, immediately not stop too early continuing Implantation Energy to inside reactor only lately; If it is too early to stop the moment of Implantation Energy, wastewater degradation is incomplete; And if reach already reaction end, but still unceasingly to the inside reactor Implantation Energy, that is certainly at the valuable energy of waste.Its structure of CN102260003A scheme as this case technical background can not provide any instant information constantly to the wastewater degradation reaction end, so, just can only estimate by experience the terminal of wastewater degradation reaction; And by experience, estimate the terminal that wastewater degradation reacts, that obviously can not be satisfactory; So, how for the wastewater degradation reaction end, constantly make neither in advance also undelayed instant information output, and in the just right moment, immediately close energy input to reactor, the technical threshold that can not despise exactly, this is seven of problem.

Eight of problem:

accept the described trade effluent of microwave and photo catalysis degradation treatment, the material that wherein is mingled with unavoidably some metal particles that originate from mechanical system abrasion process and carbon granules and so on, even if quantity is small, its existence almost is difficult to avoid, the disclosure number is that the described organic membrane separation assemblies in the Chinese patent application case of CN102260003A is installed in the microwave and photo catalysis reaction zone, being used between silica tube and membrane separation assemblies that be installed in wherein intercepts ultraviolet dividing plate and certainly do not stop microwave, so, the practical function zone of microwave must cover zone that organic membrane separation assemblies is installed described in this scheme, working mechanism based on membrane separation assemblies, its accumulation process on the organic top layer of membrane separation assemblies of the particulate of metal particle as above and carbon granules and so on is difficult to avoid, and the particulate of this type of described metal particle and carbon granules and so on, the good absorption medium of microwave energy exactly, absorbed the particulate of the described metal particle of accumulation state of microwave energy and carbon granules and so on, nature can to the top layer of its organic membrane separation assemblies of being close to produce based on heat penetration erosion mechanism continue pierce destruction, as mentioned above, due to the structures shape of this its device of CN102260003A application case can only select the polyvinylidene fluoride film material, approximately 140 degrees centigrade of this polyvinylidene fluoride film material heatproofs, really high more many than general film material heatproof, yet, the heat penetration erosion effect that its point-like of particulate that has absorbed the described metal particle of accumulation state of microwave energy and carbon granules and so on is pierced formula very easily breaks through the heatproof temperature limit of this polyvinylidene fluoride film material, for above-mentioned reasons, well imagine, pvdf membrane material in its device of this CN102260003A application case will be significantly less than the desirable work-ing life of expecting its actual service life, the structure of this its device of CN102260003A application case, determined under this structural framing, the heat penetration erosion destruction problem that above-mentioned point-like is pierced formula can't be avoided, therefore, how to get around this point-like and pierce the heat penetration erosion destruction problem of formula, also need consider, this is eight of problem.

Nine of problem:

The disclosure number is the Chinese patent application case of CN102260003A, its specification sheets open text text the 0008th section word and claim the second, catalyst particle size scope for its device can be suitable for, have a restriction, and this particle size range is defined as 20 nanometers to 100 micron.We know, under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; Especially, for the section of those less particle diameters among this particle size range, easily occur because pH value preset is not in place, the incorrect agglomeration traits that causes of pH value especially; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out the depolymerization running for coacervate; Yet we do not see that any helping immediately dissolve the structure of this problem or can immediately dissolve the scheme prompting of this problem among this CN102260003A scheme.for as the CN102260003A scheme, can only being the reactor of small scale structures because of factors restriction just like that, still can manually directly mention reactor, topple over and in the reactor outside, inspect, process above-mentioned reunion situation, so, if likely expand its capacity, just so to say, if be several cubes of large-scale reactor or the huge reactors to dozens of cube, that is not obviously manual to have toppled over problem that its operation can tackle, so, the situation of mutually reuniting for this catalyst particles, how to realize instant original position disposal, it is exactly a technical problem, this is nine of problem.

Ten of problem:

Be in the expressed apparatus structure of the Chinese patent application case of CN102260003A in the disclosure number, be used for the silica tube that screen 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 are mainly difficult by mineral-type impurity that light-catalyzed reaction touched certainly, incrustation phenomenon because this mechanism forms, be easy to be observed after the equipment long-play; Be attached to the dirty lamination of described silica tube outer wall,, although be very thin one deck, also be enough to ultraviolet radiation to electrodeless ultraviolet lamp and cause significantly and stop, this will cause the actual treatment effect of this microwave and photo catalysis reaction treating device significantly to reduce; In its reactor, the bubble of dispersed ascension is because too disperseing, wash away strength a little less than, keep the bright and clean of silica tube surface if only rely on this bubble that relatively disperses, really undertake to do what is apparently beyond one's ability, in other words, the bubble that this relatively disperses, its weak strength of washing away still is not enough to stop fully the incrustation process on this silica tube surface; In the use procedure of laboratory yardstick, above-mentioned incrustation problem is subtle, and still, on the industrial application yardstick, this incrustation problem certainly will highlight; Therefore, how under the prerequisite of not tearing machine open, immediately, effectively remove the dirty lamination on this silica tube outer wall, keep the high-level efficiency that continues of this microwave and photo catalysis treatment unit, this problem is also very important, and this is ten of problem.

11 of problem:

This problem is nine its problems that derived of the problem above addressed.Front is spoken of, and under some pH value was regulated not in place, the inappropriate situation of pH value in advance, titanium dioxide fine particles was easily reunited, and then affects its effective working interface area, affects its photochemical catalysis usefulness; The section of those less particle diameters among its suitable catalyst particle size range of especially touching upon for this CN102260003A scheme, easily occur because pH value preset is not in place, the incorrect agglomeration traits that causes of pH value especially; For the situation that this catalyst particles is reunited, be immediately to adopt an effective measure, carry out the depolymerization running for coacervate; Based on this its framework of CN102260003A scheme, operator can't immediately perceive inside reactor the situation of described reunion occurs, thereby also can't make instant disposal, thus, this is subjected to the factors restriction and can only is the further reduction of its limited usefulness of reactor of small scale structures; Therefore, among the application running of reactor, particularly, for example, among the application of possible large-scale reactor or huge reactor running, the awareness inside reactor catalyst particles main inducing parameter of reuniting how immediately, be a key issue, this is 11 of problem.

12 of problem:

based on this its framework of CN102260003A scheme, restriction due to the factors of having addressed, its reactor can only be the smaller reactor of undersized treatment capacity, the useful size of reactor inner chamber is certainly also smaller, can be used in the spatial altitude of settling curtain type film assembly among its structure of reactor inner chamber is approximately also 30 centimetres of left and right, so, even if just adopt the very curtain type film assembly of small breadth, also almost can only head on plug in the reactor the inside in two, up and down, little treatment capacity due to reactor, small size, so, after its DeR is completed, under the situation of getting rid of from inside to outside liquid, its curtain type film assembly is exposed in air unavoidably, although each time that exposes 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, to use under submerged state fully, that is to say, must be that hygrometric state uses, if curtain type film assembly contacts with air too much, can make it more aging than more quickly, Performance Ratio is decayed more quickly, and the situation that this curtain type film assembly contacts with air too much, under this its framework of CN102260003A scheme, can't avoid, therefore, how to protect the membrane module for the interception catalyzer, can use under nominal situation, can avoid too much the contacting with air,, to safeguard its normal usage energy, guarantee its normal service life, problem that needs are faced exactly, this is 12 of problem.

13 of problem:

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

14 of problem:

Based on this its framework of CN102260003A scheme, among its running, water pump to reactor inner chamber filling waste water, itself can't differentiate inside reactor water level height, operator can only rely on experience or range estimation in time to close the pump motor of this filling waste water,, if experience error or range estimation response are not prompt enough, be easy to occur cause thus unnecessary trouble because of the excessive situation of overflowing reactor of waste water filling; 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, fully 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 of experience, slip up or estimate response not in time, causing this to draw water can't in time shut down 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, this is 14 of problem.

15 of problem:

based on this its framework of CN102260003A scheme, among its running, the air that pumps into to quartzy tube chamber, be subjected to uviolizing, wherein a part can be converted into ozone, what so form contains ozone-air, most of can release by force feed to micro porous aeration head place, but, we know, magnetron structures itself does not have vacuum-tightness, and, the junction of waveguide and magnetron does not generally have vacuum-tightness yet, therefore, the described ozone-air that contains with relative positive pressure must have the sub-fraction reverse magnetron place structural region of scurrying in ground of can taking advantage of a situation, and its structural member material of magnetron comprises that generally speaking its case material does not possess the ability of resisting the ozone corrosion yet, so, thus, reverse scurrying into containing ozone-air and must forming corrosive nature to the magnetron member of magnetron structures zone, the power of this corrosive nature may be subtle within the short period of time of laboratory yardstick, yet, time is slightly long, certainly manifest, the problem that this contains the reverse channelling of ozone-air and corrodes the magnetron member, can not be avoided, this is 15 of problem.

16 of problem:

This case method also can allow further to add following steps again: within described back flush type tubular fibre membrane microfiltration strainer and described back flush type hollow-fibre membrane ultra filtration filter are immersed in tank; At its sidewall of this tank or its bottom, another group ultrasonic transducer is installed, this another group ultrasonic transducer contains a ultrasonic transducer individuality at least, this another group ultrasonic transducer is used for the radiation high-frequency ultrasonic, and this high-frequency ultrasonic refers to the ultrasonic wave of frequency in the 100kHz-12MHz scope; This another group ultrasonic transducer is connected with another HF oscillation electric signal producer.Rely on above-mentioned being somebody's turn to do to add step, in its back flushing operation procedure of membrane module,, by means of there is no the extremely weak described high-frequency ultrasonic of cavitation damage or cavitation damage, can more mildly assist backwashing procedures to remove those obstinate catalyst that adheres on the membrane module working interface.

advantage of the present invention is, microwave constrainer with the cage shape of metal material, electrodeless ultraviolet lamp is wrapped among its inner chamber, and with its inner chamber of microwave constrainer of this cage shape and the waveguide UNICOM that is derived from magnetron, its whole locations of structures of the microwave constrainer of this cage shape is also the inside at described silica tube, this silica tube is to isolate for the gas-liquid phase, the performance screen protects the member of effect, by described step, within the microwave that comes via the waveguide transmission is constrained in its effective workspace, contained the unhelpful dissipation of microwave to peripheral waste water water body, and a little less than building microwave between microwave constrainer outer wall and reactor wall irradiation spatial domain or microwave zero irradiation spatial domain, this silica tube and being placed into is positioned at the upper area within its lumen of megaphone-shaped member of unsettled, vertical state of being of reactor inner chamber, the step of this case method also comprises: the size in irradiation spatial domain or microwave zero irradiation spatial domain a little less than extending on three-dimensional, enlarging the described microwave of inside reactor, by this step, can significantly expand the design volume of reactor, allow reactor list tank wastewater treatment capacity significantly to promote, and need not worry again that microwave energy dissipates too much in unhelpful waste water water body temperature-rise effect.

In the situation that adopt bright finished Stainless Steel Wire cylinder mould as the microwave constrainer, perhaps, make the microwave constrainer in the situation that adopt the punching stainless steel plate through mold pressing, welding or splicing process, specular reflection mechanism via complexity, can to greatest extent the UV-light from electrodeless ultraviolet lamp be transferred out, and make up to greatest extent himself entity of described metal cage light is blocked, absorbs the loss that causes.

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

On the other hand, this case method is made the cyclic motion of relative big scale with described megaphone-shaped member guided liquid-flow, ascension contains the ozone gas burble and can pull, guide the lumen fast rise of the liquid stream of inside reactor along this megaphone-shaped member in reactor, and after impacting, pass through silica tube periphery photocatalytic degradation conversion zone, spread to surrounding by top area, sink via neighboring area, arrive reactor intracavity bottom zone, within the stub end trunking down of this megaphone-shaped member arrives the lumen of this megaphone-shaped member, continue its circulation again; The liquid circulation campaign of this relative big scale that is guided, help to guarantee the homogenizing of inside reactor liquid degradation reaction process, and this, for large-scale DeR device, is necessary.

The related UV source of this method of this case is to rely on microwave excited electrodeless ultraviolet lamp, the uv-radiation characteristics of this lamp type can be accomplished high-power, high strength exactly, yet the Effective depth penetration of ultraviolet ray in liquid water body only had an appointment 20 centimetres, therefore, zone within peripheral approximately 20 cm distance of silica tube is effective area, and this zone is exactly the efficient zone of photochemical catalysis oxidative degradation; This case device is with described megaphone-shaped member, pack is from the bubble flow of numerous micro porous aeration heads, its concentrated area is discharged towards silica tube periphery photochemical catalysis oxidation effective area, the oxygen atmosphere that this mode helps to improve the described effective area of silica tube periphery is supplied with intensity, helps accelerating ultraviolet catalyzing oxidizing degrading reaction process.

based on this method of this case, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, to realize by significantly expanding the design volume of irradiation zone a little less than microwave zero irradiation zone or microwave, so, from the appearance, the lateral dimension of reactor, longitudinal size is all significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., in the situation that the Sheng liquid degree of depth is enough dark, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust up hill and dale ozone contained in bubble, thus, containing ozone composition oxidation potential in the ozone-air bubble utilizes incomplete problem to be solved, and, because long ascension path causes ozone to exhaust, just can not be entrained with again the ozone that can cause environmental pollution in reactor tail gas.

This method of this case and with external multistage filter, reach the interception step by step to the collision fragment of the small scale from coacervate macrobead to ten number nanometers of catalyst particles, be close to recovery, reuse photocatalyst up hill and dale, be close to the secondary pollution of taking precautions against catalyst loss up hill and dale and causing; This is hold-up interception method and can protect secondary filter to make its filtration passage avoid the rigid obstruction of large particulate matter step by step; Wherein the pre-filtering aperture of the first step is between 5 microns and 300 microns, and its aperture of the micro-filtration of the second stage is between 25 nanometers and 1000 nanometers, and its aperture of the ultrafiltration of the third stage is between 15 nanometers and 2 nanometers; Such hold-up interception method, can fully tackle nano level photocatalyst, and it certainly can be close to and tackle up hill and dale this median size of gas phase titanium dioxide P25 is the catalyzer of 21 nanometers; Preamble is addressed, the gas phase titanium deoxide catalyst of nano level P25 and so on, it is the commercially available catalyzer that can buy in a large number, also weather resistance, stability, the known good photocatalyst of UV-light wave band photocatalysis performance, certainly, it is also in fact to pay the utmost attention to the photocatalyst of selecting in industrial scale applications; This case catalyzer hold-up interception method is complementary with the virtual rating of catalyzer market supply, actual kind, merges mutually.

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

The related strainers at different levels of this method all have commercially available, commercially available strainers at different levels, the discharge outlet of draining-off sewage when its sewage draining exit is exactly back flushing, this class back flush type equipment is used in this case, to tackle step by step catalyst particles, originally the sewage draining exit of commercially available equipment, be used as being held back the recycling delivery port of catalyst particles or refluxing and use delivery port again by conversion in this case.
