Can exhaust the microwave light chemical catalysis wastewater degradation reactor expansion method of ozone

Technical field

The present invention relates to a kind of microwave light chemical catalysis wastewater degradation reactor expansion method that can exhaust ozone, 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, as excitaton source with microwave, excite electrodeless ultraviolet lamp emission ultraviolet ray, be mixed with the suspension liquid of photocatalyst titanium dioxide in the liquid internal irradiation, this electrodeless ultraviolet lamp is shrouded by silica tube to be protected, 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 the aeration zone, the upper area of this inside reactor is the microwave and photo catalysis reaction zone, this scheme is also with the built-in membrane separation assemblies of reactor, carry the water of analysing after purification, and realize that with this membrane separation assemblies holding back again of photocatalyst titanium dioxide fine particles use, this scheme is also set up dividing plate between non-polar ultraviolet light source and membrane separation assemblies, be used for preventing that ultraviolet ray is to the radiation injury of 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 undoubtedly 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 has seven; These seven problems are seven 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 causes the material of membrane separation assemblies to be limited to more expensive PVDF material.Have again, UV-light possible in device is revealed, may touch 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 has its apparent advantage compared to the ceramic filter assemblies; About this point, for the personage of filtering technique specialty, be known, here do not launch to give unnecessary details.

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, other filter opening of larger micro-filtration level aperture can only be selected in membrane separation assemblies its aperture that is used in conjunction with this cleaning mode, other filter opening of this micro-filtration level aperture is the 0.1-0.2 micron, about this point, have clearly in open the 0009th section word of text of this case and claim 3 equally and limit, 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 can't be blocked less than the catalyst particles of 100 nanometers; 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 photodegradation particle catalyst 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 give unnecessary details, 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 can make a big purchase in large quantities 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 its catalyst interfacial area that can provide of photocatalyst about 21 nanometers, 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 collide with wall 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 its cleaning solution for the interception structure scheme of 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, improving its waste water treatment efficiency, is a significant technical problem that merits attention.

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

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

Four of problem:

The scheme that this kind showed by CN102260003A, the bubble of the inner dispersed ascension of its retort for the cyclic motion of the relative big scale of driving a reaction tank internal liquid, is contributed 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 efficient 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 the 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 the 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 disengage from micro porous aeration head, 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 analyze with the Sheng liquid degree of depth of 40 centimetres, 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 be 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 squeezed in one meter dark tank via micro porous aeration head with the normal domestic use ozone machine and contained ozone-air, 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 requires the expenditure of energy, and therefore, operator are bound to wish, when the wastewater degradation reaction proceeds to terminal point, 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 undoubtedly 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 point of wastewater degradation reaction; And estimate by experience the terminal point that wastewater degradation reacts, that obviously can not be satisfactory; So, how constantly make neither in advance also undelayed instant information output for the wastewater degradation reaction end, and immediately close energy input to reactor in the just right moment, the technical threshold that can not despise exactly, this is seven of problem.

Advantage of the present invention is, partition is forced in microwave exposure spatial domain to the wastewater degradation inside reactor, this case is protected electrodeless ultraviolet lamp and screen thereof with silica tube with metal cage and is shrouded in it, metal cage retrains the effect spatial domain of microwave simultaneously, so, spatial domain between silica tube outer wall and metal cage inwall has formed a microwave excitation and has promoted with the wastewater degradation of photochemical catalysis coupling regional, and, the multiple hole of metal cage or the structure of many meshes, do not affect waste water and reactor lower part bubbling and on air free into and out of this spatial domain; And the spatial domain between metal cage and reactor wall, the waste water water body is contained the simple pyrogenicity absorption of microwave, has significantly weakened thus the unhelpful dissipation of microwave energy; This case method force to be cut off the microwave exposure spatial domain of wastewater degradation inside reactor, and based on this, this case method allows to realize the significantly expansion of single tank reactor volume by significantly expanding the design volume in irradiation spatial domain a little less than this microwave zero irradiation spatial domain or microwave; This case method allows reactor list tank wastewater treatment capacity significantly to promote, and need not worry that microwave energy dissipates too much in unhelpful waste water water body temperature-rise effect again.

Rely on this case method, the design volume of microwave and photo catalysis wastewater degradation reactor is that single tank wastewater treatment capacity can be expanded to several cubes to dozens of cube; The volume that even single tank is hundreds of cubes also allows; Rely on this case method, after expansion reactor for treatment capacity, can reduce significantly the frequency of the wastewater degradation operation of equipment of a complete set, whole process, be conducive to the saving of human and material resources.

This case method is under the prerequisite of taking into account described microwave and photochemical catalysis coupling, for the significantly expansion of relevant its design capacity of wastewater degradation reactor provides a broad space.

on the other hand, among this case method, its high-density ascension bubble flow that discharges of described cluster-shaped micro porous aeration head cluster, in the ascension that makes progress, and wrapped folder, carry, guided liquid-flow, form a kind of motion that is similar to the fountain form, in this kind motion, the high-density air burble wrapped folder that is derived from described cluster-shaped micro porous aeration head cluster liquid to the metal cage region gush and on, and then relatively the concentrated area is impacted in metal cage, outer close position, be subjected to described high-density air burble wrapped folder, the liquid stream that carries is impacting, in metal cage, after outer close position, liquid layer by top area spreads to surrounding, sink via the neighboring area, arrive the reactor intracavity bottom regional, again through the wrapped folder of its high-density ascension bubble flow that discharges of described cluster-shaped micro porous aeration head cluster, carry, continue the motion that it is similar to the fountain form, so circulation endlessly, the liquid circulation campaign of this relative big scale that is guided helps to guarantee the homogenizing of inside reactor liquid degradation reaction process, and this for large-scale electrodeless ultraviolet light catalysis DeR device, is necessary.

Its UV source of this case method is to rely on microwave excited electrodeless ultraviolet lamp, the uv-radiation characteristics of this lamp type can be accomplished high-power, high strength exactly, yet the Effective depth penetration of ultraviolet ray in liquid water body only has 20 centimetres of left and right, therefore, zone within peripheral approximately 20 cm distance of silica tube is the effective area of photochemical catalysis oxidative degradation, and this zone is also simultaneously the efficient zone of microwave excitation promotion and the coupling of photochemical catalysis oxidative degradation; Partly or entirely being coated by permeable, the ventilative also metal cage of printing opacity of this effective area; This case method is to be positioned at the described cluster-shaped micro porous aeration head cluster under metal cage, come the concentrated area to discharge highdensity ascension bubble flow, make its as concentrated area as fountain towards as described in the effective area discharge, the oxygen atmosphere that this method helps to improve described effective area is supplied with intensity, helps the accelerated degradation reaction process.

based on this case method, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, that the design volume of irradiation zone realizes a little less than microwave zero irradiation zone or microwave by significantly expanding, so, the lateral dimension of reactor, longitudinal size is all significantly to expand certainly, therefore, inside reactor is contained the liquid degree of depth and can be deepened significantly similarly, for example, can deepen to one meter, two meters, three meters, four meters, five meters, six meters, even ten meters, etc., in the situation that the Sheng liquid degree of depth is enough dark, contain ozone-air bubble ascension path sufficiently long, contain the time sufficiently long that the ozone-air bubble contacts with water body, in its ascension process just can with abundant reducing substances fortune, and thoroughly or be close to and exhaust up hill and dale ozone contained in bubble, thus, contain that in the ozone-air bubble, ozone composition oxidation potential 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 case method is with external multistage filter, reach the interception step by step from the collision fragment of the small scale of coacervate macrobead to ten number nanometers to 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 the micro-filtration of the second stage its aperture is between 25 nanometers and 1000 nanometers, and the ultrafiltration of the third stage its aperture is between 15 nanometers and 2 nanometers; Such hold-up interception method can fully be tackled 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 to 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, in this case method, catalyzer interception mechanism is external mechanism, and based on the method, its filter core needn't be soaked in the liquid of the strong oxidation of inside reactor, strong uv irradiation, therefore, can needn't consider the tolerance to uv irradiation, strong oxidizing condition fully, like this, just there is no restriction aspect extraordinary tolerance selecting of filter core material, 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.

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

above address, based on this case method, the capacity of reactor or treatment capacity can significantly be expanded, described significantly expansion, that the design volume of irradiation zone realizes a little less than microwave zero irradiation zone or microwave by significantly expanding, 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, contain that in the ozone-air bubble, ozone composition oxidation potential 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, only ought be subject to processing that in water body, reducing substances is in organic pollutant is degraded totally, in water body, again without the organic pollutant that can supply ozone oxidation reaction, those unnecessary ozone just might no longer consume and see through long ascension path effusion liquid level, the front is spoken of, among some problems that this case solves simultaneously one, it is the circulation of the relative big scale of enhanced reactor internal liquid, this systemic circulation mechanism of having strengthened has been facilitated the uniformity of its contained organic pollutants DeR process of inside reactor liquid, thus, at several cubes that its corresponding framework of this case method allows to dozens of cube even under the processing capacity framework of hundreds of cube volume, have above the inside reactor liquid level in the ozone effusion, the DeR that namely shows inside reactor has reached terminal point, and be the terminal point that the whole uniformity of internal liquid ground reaches DeR, this terminal point determining factor is that the condition that can provide with this case scheme is complementary, this case is at its exhaust port position installing ozone sensor of reactor, ozone detected in this locations of structures, just mean that the inside reactor DeR reaches home, ozone sensor and connecting with the composite structure of ozone content indicating meter with ozone attention device or ozone content indicating meter or ozone attention device, be used for providing indication information accurately to operator, this case and the electric signal that ozone sensor is exported send power-supply controller of electric to by cable, this power-supply controller of electric also connects with magnetron and pneumatic pump respectively by cable, the power-supply controller of electric described electric signal received according to it carries out the power switch action, certainly, its function mode is, receive in the signal that ozone that ozone sensor sends overflows at power-supply controller of electric, autoshutdown leads to the power supply of magnetron and pneumatic pump, this case Using such method can in time be known the terminal point of inside reactor DeR process, and Using such method, when reaction reached terminal point, the power supply of autoshutdown magnetron and pneumatic pump in time stopped so can avoiding unnecessary energy dissipation to the inside reactor Implantation Energy, and, this case Using such method, in DeR reaches home, can in time close the power supply of described magnetron and pneumatic pump, this power-off action is synchronous, the same generation process of ozone that stopped in a flash also, because ozone generation process is in time stopped, just do not have over a large amount of ozone that need and disengage from described exhaust port, thereby avoided unnecessary secondary pollution or said secondary pollution, this case method has determined that its corresponding framework does not have ozone more than needed can supply discharging.

In brief, this case method has reached by utilizing metal cage to retrain more closely the method for microwave the target that allows the reactor design capacity significantly to expand; Simultaneously, its method has also been strengthened the cyclic motion of the relative big scale of inside reactor liquid; The method and to be set up in described its highdensity bubble flow that is discharged of cluster-shaped micro porous aeration head cluster under metal cage realizes the significantly lifting for the oxygen supply concentration degree in emphasis DeR district; The method and reached for the nm-class catalyst particulate from the collision fragment of its coacervate macrobead to ten number nanometers widely, meticulous interception; Based on the method, the selection face of its filter core material also thereby expanded; Its DeR endpoint information can in time be known; Can autoshutdown in its DeR terminal point to the energy input of reactor; In its DeR terminal point, also automatically in time stop the generation process of ozone, avoided unnecessary secondary pollution.

This case method has solved described series of problems totally.
