The specific embodiment

The present invention includes a kind of set composite that dyes gas at vertical cleaning tower supernatant contaminate; On cleaning tower; Sprinkling water droplet (molecule) through serial connection is blown and is created multilayer cascade and fluosolids (suspension; Spray water); Be used for pollution abatement through introducing considerable liquid oxidatively effect, comprise, condensation (liquefaction) and tackle (gas componant is accumulated in the surfaces externally and internally (in pore) of solid) along with adsorption process and the absorption in the biological decomposition process of pollutant in the system of the sealing of rinse water treating apparatus (making the gas pollutant dissolving) through liquid.

This most distinctive function of system is to clean, and through using a large amount of nozzle 5, this nozzle is installed on many layers of inside of vertical cleaning tower of cleaning equipment; Allow to produce a considerable amount of water droplet and water smokes 9 with very big surface, this surface is created in the washing fluid, is deposited on many circular cone concentric circles 6; It is installed on the cleaning tower wall, is between some ring section 24 of sprayer (nozzle), has caused the formation of waterfall subsequently; Increased the time that water keeps the flotation material in cleaning tower, this is a key factor of improving purge gas, because a large amount of contact between liquid 9 and gas; And exposure for a long time, guaranteed strong favourable inflation, therefore; Cleaning fluid will be the main target of the biology conversion (decomposition) in adsorption filter to the absorption of oxygen; The setting of this filter is adjacent to washer, is used to purify cleaning fluid, keeps the least concentration of water pollutant.

The adsorbent (being used to catch the material of pollutant) that occurs with the active carbon form has caused when it turns back to recycling can the elimination of pollutant in the cleaning fluid.

The organic pollution that from gas, removes is used to feed special bacterium; And through they decomposition; And all hydrocarbons are changed into carbon dioxide and water; Thereby the adsorbate of regenerating (active carbon) can constantly absorb the pollutant by the cleaning fluid supply to such an extent as to they are remained under the good condition it always, then clean water is turned back to circulating tank; Circulating tank often has the concentration of lower pollutant; In order to guarantee the maximum availability of cleaning process in this method, provide a large amount of oxygen composition in the cleaning process in recirculated water, be used for guaranteeing for bacterium in order to breathe the maximum availability of requisite oxygen in biodegradation process.

Cleaning tower combines synchronously, and the purification and the oxidation in water and the sewage of the air of generation become a perfect solution; In order to destroy contaminants from gas; Comprise solid, liquid and gaseous state organic products reach through transferring to them the smell in the rinse water, and this solution is in the closed circulation; It is constantly handled through biofilter; This filter has biological decomposition function, can organic principle be changed into carbon dioxide and water, and removes the non-organic principle of outside.

On the contrary; Thermal oxide and common cleaning integrated system according to the present invention can be realized real gratifying result; Make the organic pollution of removing in the gas in each stage up to 97% (90 percent); The operation cost of eliminating undesired material is also very low, and this constitutes, and excitation is implemented and the strong motivation of operation native system.

According to solution of the present invention; A kind of biological treatment system that the present invention includes; The target that can reach us also promptly obtains the more cleaning and the purification of the gas of efficient; And the target of guaranteeing to remove (byproduct of purification process) sewage is effectively actual in processing procedure, in biological treatment system, will use special method.

Be used for the cleaning tower (Fig. 1 and 5) of the oxidation of purge gas and cleaning fluid, it is characterized in that, it has many nozzles 5 of arranging with the series connection form; Under this mode, in order to make that gas can be through 24 layers of all ring sections, wherein ring section layer promptly is the place that spray liquid takes place; Capacity and ability based on cleaning tower; Each tandem compound comprises one group of 10 nozzle, and they are in order to guarantee the uniform concentration of water droplet, and they are placed on same plane uniformly.For reach maximum validity (interface (contact-making surface of gas and liquid) is sympathized and is considered to be the mixed coefficint of water environment and gas (perhaps air), and gas or air by the maximum absorption of atomizing of liquids; And minimum friction loss, should carry out with 15 and 45 degrees centigrade angle owing to the saving and the sprinkling of energy, consider cost/profit ratio; Best angle is 35 degrees centigrade, and the angle of pipeline delivery nozzles should be identical with the angle of atomized spray or approximate, sprays in order to avoid pipeline interception frequency spectrum; The ring 6 also by with successively decrease the order top (Figure 18,20 and 21) that between the reflecting point of two atomized liquids, always reaches cleaning tower connected in series, the minimizing on its gas velocity that is used for confirming to flow through; Based on advantage,, upwards lift and remain in the suspended state through loading small-sized and light-duty water droplet from the lower floor's (sphere) that moves up with higher speed; The water droplet that produces in the intermediate layer of cleaning tower remains on average speed, and the volume of the little water droplet of tackling by atomizing is bigger, heavier; At cleaning tower top speed lower (Figure 21), ring 6 or lateral direction element that water droplet is sprayed in these interceptions are very important, because they confirm and the interior speed of differentiation cleaning tower; It has increased the suspension amount to a great extent and has descended, and helps to increase the absorption of oxygen and gas, the influence that is recycled; Because contact-making surface is big, caused producing numerous decline waterfalls 25, they drop on the wall of cleaning tower; Drop to next ring, they are collected and further drop to lower ring there, further; Add every layer spray and drip and create (Figure 20) real waterfall, wherein, in the decline process owing to water droplet and the influence of dripping the turbulent flow that the basis of the cleaning tower of beating produces; A large amount of oxygen, gas and circulation of fluid connect mutually, accomplish in order to carry out biological treatment conditions needed subsequently, especially when organic product for example the smell etc. of solvent, infiltration from fat; Feather, the pollutant that the decomposable process of blood and material produces is removed.

And along with the longitudinal structure of serial nozzle and the multistage cleaning technique (Fig. 1) of lateral loops permission application, a plurality of spheroids that perhaps are divided into have constituted the notable feature that the utilization in same cleaning tower (Fig. 5) is cleaned.

According to designing as follows, this equipment comprises the cone that is divided into a plurality of parts 8 of concentric arrangement, and is co-linear with one another as the device (Figure 22 and 23) of circulation separator 7; Make spheroid away from each other through creating overlapping shutter, and can make gas flow to the top, still from the spheroid bottom; Current can't be reduced to the spheroid bottom from the spheroid top; Because it separates into independent parts with neutralising fluid, because in the inside of same cleaning tower, differing absorption and reaction appear in multiple cleaning fluid cognition.Therefore; In first spheroid, can use acidic cleaning solution to carry out cleaning, the alkalies that cleans usefulness uses in second stage, even in the 3rd ball, has no under the interactional possibility; Utilize the minimizing of the cleaning fluid in the oxidation liquid; The demand of careful observation action flowed in the different jars (Fig. 8) in order to the guiding fluid when it provided separator interception fluid, to such an extent as to they can return through the suitable nozzle 5 that cleans specific spheroid.

Continuous purification water system in the purging system; Its objective is the elimination organic matter; And in order to prevent increasing of the solvent strength that causes saturated situation; Prevent promptly that also organic concentration from reaching peak and prevent that the water on the cleaning fluid from having lost a certain specific compound dissolution characteristics, thereby limit, even eliminated the ability of the continuous absorption of contaminants of cleaning tower.

The characteristic of the cleaning of this and biological agent combination and operation can cause guaranteeing the advantage of destroy contaminants from gas; Eliminate the pollutant in the gas with the supply of guaranteeing a considerable amount of oxygen and with the pattern of fixing and sealing; The realization of guaranteeing function is conveying continuously and the effective sewage disposal system subsequently through cleaning fluid; In sewerage, be decomposed as the pollutant of the nutritional labeling of microorganism and change into carbon dioxide and water, water is cleaned and is prepared to absorb effectively new organic products once more.

Continuous rinse water forms a loop, wherein caused continuously water being pumped into processing system and cleaning tower, and the low concentration that has kept solvent and organic products, thereby satisfied the high efficiency key condition of cleaning process.

In order to improve the attraction degree of right this pollution control device of enterpriser; Because there is disposal of pollutants in process of production in their enterprise always; In order to impel enterprisers to be ready to use the equipment of these pollution abatements in process of production, the enforcement that must restriction and the cost of operation.Because following true: the heat regeneration suction of traditional absorptive element needs complex apparatus; The labour of labor; Comprise and often to remove and to change these materials; Because the cost that microorganisms reproduction needs is lower, plants a colony the mode of absorptive element through microorganism and carried out the application of reforming in this system and equipment.

Type, quality and organic concentration according to filter are classified, and its structure has multifrequency nature.Basic, vertical cylindrical tank (referring to accompanying drawing 3 and 7) has a central tube 16, is used to handle the sewage of introducing; It comprises that distributor 15 is in order to distribute the sewage of cleaning solution or bottom; And therefore the current that it can uniform distribution makes progress need not produce preferred path in the phase I, and wherein the phase I uses mesh material to fill; Thereby make all flow of liquid through mesh and stay the part pollutant; The remaining pollutant of interception in second chamber of being filled by carbon granule then, is placed on the 3rd chamber 22 collection and purification water at top and it is led back to recirculation tank 1; Accomplish once circulation according to this, perhaps again under the situation of high concentration, the 3rd chamber is directed to second stage 4 to it, the filter array of then need flowing through this moment.

More complicated system its objective is raising to using the continuous regeneration of biological absorption in the organic decomposable process, at this moment need utilize the multi-stage biological filter of three or more processing section.

In order to make outer surface increase to maximum; To obtain only geometric path; And the best distribution that obtains the input contraction of optimum capacity and removable powder bed, can utilize active carbon as sorbing material, because the high-absorbable and the small size property of carbon dust moment suction; It has caused it to be deposited in traditional system bottom, and on the layer of contiguous bottom, assembles.

The obstruction of the nozzle on the sewage distributor that is used for biological treatment device because this biological treatment device has carbon powder particle, therefore causes it to lose when taking place to stop up in system its suspension characteristic; At this moment utilize the smooth flexible pipe 18 of a lengthening; The one of which end has horizontal interface, and flexible pipe is set up in the following manner and installed, and it can be opened when distributing sewage; When current stop, closing, this structure can prevent that particle from arriving distributor 15.

In this case; No matter phase I or second stage; The part of the first 26 of jar is filled carbon dust; Mix when sewage injection nozzle and water jet delivery port (sprinkler) utilize compressed air guiding high energy, this mixing makes the powder in the suspension set up surface fully uniformly, and the concentration of this uniform outer surface is controlled in the scope of 5-70%.Dynamic surface does not allow in the input spheroid, to have high concentration carbon; The factor of setting up the input spheroid is to inject together linked together with the set of regulating input sewage; Wherein the sewage of input is by centrifugal unloading; So its can not set up preferential route with the reduction system in the negative effect aspect the efficient, it has increased its effectiveness.

In addition; Because the flowability of the suspension that phase I powder and sewage are set up can be changed easily; Change in this and need not go to remove or block system and its filter can reach, the second portion 27 of jar, its effect is to accomplish first and prevent that powder from rising to next part; Guarantee to form huge labyrinth by the outer surface that mesh material 19 is processed; Wherein the early stage sewage handled of phase I must flow through it and stay carbon powder particle and pollutant, the mesh material here is made up of fiber freely, this part is filled with the mesh material that has coated active carbon; Its activated carbon particles stops in the labyrinth, and this is permanent to have constituted the outer surface that makes that microorganism species effectively exposes.

Because a fact, promptly fluid closely contacts with these surfaces, has occurred the decomposition of the minimum concentrations of organic principle in the sewage.The 3rd part 28 often also is last part, though be not in all technical schemes, all to occur; It is filled by durable active carbon and forms or be made up of the mixing of adsorbate, and through this adsorbent, clean fluid is flowed through; Constituted the zone of the residue in the destroy contaminants, after this, sewage is directed to purge of gas or other stages again; These stages carry out successively, and often rely on existing pollutant kind and concentration.

For the cleaning tower of accepting a special construction, there, the liquid that band cleans is by meticulous billions of water droplet that is ground into; These are different with the processing in the legacy system, and in traditional system, they contact the longer time with gas; Thereby through absorption, pollutant is transferred to biofilter, there; All impossible preferential routes occur, if not through cleaning effectively, gas be can't through this system (for example; Packed column), guarantees the foundation in numerous zones of vertical structure of fluid layer and atomizing, since it allows the increase of dissolved nutrients; It has satisfied the scope for the needed physical condition of good associating between purge of gas device and the wastewater treatment plant, therefore, can set up a kind of system that in single operation, can destroy and eliminate organic pollution together.

A biofilter is through stepping filter and this systems incorporate, and it can remove insoluble material like paint, powder, and lubricating oil, oil is cleaned the refuse that tower is intercepted and captured with other.

The application of this system is very necessary, especially avoids the similar jammed and pollution problems that is used in the absorption element in the biofilter of emerged in operation as needs.Basically; It possibly comprise a distribution tank (Fig. 2) wherein, and the flotation material for example paints or dyestuff constantly overflows from the distribution tank of cleaning tower and flow to distribution tank, from distribution tank; It can removing or sometimes even be filtered by machinery; Yet if accomplish such function, saturated filter must be removed subsequently.

Biofilter is a kind of system of disposing of sewage of can really being used to, and this sewage has comprised a large amount of organic substances, particularly solvent.Yet, a lot of other compositions are also arranged, for example comprising feed, lubricating oil; Oil, blood, bone; Fish food etc., they all have specific smell and can in such filter, be decomposed, but it can be quite simple can be used in the filter that removes them; For example, have a single chamber, the frame for movement of its sealing comprises a kind of sorbing material of specific quantity or the place that the group that is filled in microorganism or bacterium fixing or that move assembles.This is a characteristic relevant with the microorganism demand.Contaminated fluid this structure of flowing through; The jar of the filling that its employing sorbing material and/or filler carry out; After staying organic contamination, decomposed by microorganism then, wherein microorganism occurs with the form of multigroup group; And it provides nutrient and changes into carbon dioxide and water to them, the sorbing material of regenerating simultaneously for these compounds.Most critical be this structure of guaranteeing this element, wherein, this element can make the preferential route that fluid can not occur overrunning, and has prevented that therefore the gathering of pollutant from contacting with surperficial, and the absorption of filtering material.

The mesh material 19 that uses can be processed by the embossing fiber that omits arch, for example from following material: still be in semisolid PP, PF; PVC and polyamide after these materials leave the embossing stage, add the for example powder of carbon or active carbon of sorptive material in cooling procedure; Coat these powder then; Again, the fiber that rocks and vibrate entanglement is to form real labyrinth, and this is the ideal structure that guarantees best contact between sewage and the microorganism.This structure that the fiber that is coated by active carbon is processed is the place of desirable accumulation microorganism, is noted that carbon absorbs the inboard of its molecular structure with organic compound, and gap that the there is huge or pore have produced the attraction that stops and absorb these compounds.

The characteristic of the absorptive element of using among this paper is; It has macrovoid and size above 3 microns; The biologically active that constitutes key feature of the present invention does not allow the state of reaching capacity, because it has kept the reproduced state that continues through microorganism, the existence of macrovoid and appropriate size can offer the more surface of microorganism and regional than the outer surface of general absorption molecule; Therefore, allow huge micropopulation to accumulate in the limited surface of adsorbate.

For fear of the appearance of this situation, suppressed to close on the decomposition reaction of the microorganism of sewage inlet when organic substrate concentration is too high, such inlet should be installed in different layers.

Biologically active comprises the decomposition reaction that the microorganism of living in groups in a large number on sorbing material causes, this has caused setting up the enzyme of enrichment cleaning fluid, has therefore improved the efficient that restarts circulation time purge gas process.

By this method; In cleaning tower, sewage is imported in recirculation and the atomizing processing again, and at this moment sewage removes new pollutant at any time with form cleaning, enrichment; Simultaneously; Prevent the increase of the concentration of ordinary dissolution in the recirculation tank of sewage, this concentration invariably accompany with the operation of good water quality with the maintenance, use, wearing and tearing, the operating cost that reduce pump and eliminated the frequent expense that needs to change cleaning fluid, these are key factors of the possibility utilized of restriction legacy system.
