Description

A kind of organic waste dynamic disposal technique
Technical field
The present invention relates to the dynamic disposal technique technology of organic waste.Specifically relate to moist organically biological purifying process technology and support equipment.
Background technology
In recent years, the development just continuously and healthily of junk finishing sector, and from the process of the biologic garbage of construction industry, trade and business and industry and reason problem also day by day remarkable.Research for the purification process technique of biology, machinery-biological and chemical-biology is also all the more deep.As everyone knows, animals and plants solid waste is made fertilizer heap, there is aerobic and transform and be degraded in organic waste wherein under microbial process.Except aerobic corruption is applied to organic waste process, anaerobic fermentation technology also can be applied to this field, and anaerobic fermentation technique only needs emptying gas, and without the need to the effect of microorganism.In the application of reality, these two kinds of technology can be applied separately, also can combined utilization.
Composting technology is a widely cognitive corrupt technology of aerobic, and it is loaded by refuse in corrupt container, and Keep agitation, at most through one to two days, just can be converted into fresh compost.Enter static decay process afterwards, need in this process to pass into gas in refuse, without the need to stirring, composting under static condition.But this processing requirement uses the container of appropriate volume, because also need fermenting twice reaction occurs.First in dynamic decay process, by continuous stirring, have sufficient oxygen in refuse, anaerobic ferment process then requires can not have oxygen in refuse.
The organic waste rubbish reported in recent years or the anaerobic process of domestic refuse are a kind of anaerobic fermentation technology, require to get rid of gas, cause weak thermopositive reaction produce biogas products thus cause refuse to degrade.Organic waste leave standstill in the reactor, leach soluble inorganic matter or organicly take thing from treated waste with vat liquor.Also require in this process to get rid of gas, under anaerobic, utilize hydrolytic action to reach decontamination effect improving.
A drawback of above-mentioned Technology is exactly, because refuse process all needs the static decomposition course through, under this static condition, vat liquor or other liquid can flow through refuse through by-pass channel, and that is liquid can pass through refuse along the path of least resistance.This just causes the existence in dead band, and even a large amount of refuse cannot be leached.
Summary of the invention
Patent of the present invention improves biopurification treatment process, is applicable to the purifying treatment of moist organic waste.By improving technique technology, eliminate the drawback of original technique, and substantially increase decontamination effect improving, the expenditure reduced in decontamination process.The core of this Technology is combined utilization extract technology technology and the corrupt Technology of aerobic, in this process, by the combined utilization of independent Technology, to reach the object of high-efficient purification organic waste.
An advantage of this technique is just to apply dynamichandling Technology.This dynamichandling Technology avoids the short path of liquid, or vertically, the phenomenon that directly flows through of level, therefore vat liquor fully, fully can contact with organic waste, and there will not be dead band.Vat liquor continue or discontinuously with organic waste object contact, the simultaneously reaction of organic waste object generation aerobic degradation.In this process, vat liquor flows to bottom from top pouring, and regular from top vent to bottom, makes whole refuse body that aerobic degradation reaction completely occur.
According to present invention process technical requirements, the reactor apparatus that design is applicable to, there is corrupt DeR in organic waste in this reactor.The appropriate access device of equipment de-sign, to ensure that refuse can load, the pouring of vat liquor and removing and the passing into of live gas.The advantage of reactor running is to apply through-flow pattern, namely a kind of circulation mechanism, and namely material enters from one end of reactor, slowly transports in the reactor, arrives the other end of reactor and is removed.Even if a benefit of this through-flow pattern is with regard to being that all substances in whole reactor have different performances, through stop in a few days, often kind of material all can experience different process, through being completely degraded through each position of reactor.So the aerobic of different positions in the reactor, the Different treatments of different time is corrupt, has the injection needing vat liquor and live gas.
The reactor purified for mass treatment in the present invention is very convenient to flexible operating.Refuse joins in container, and by the impact of the composition of reactor, volumetric loading, temperature and water-content, the aerobic of refuse transforms can in the length detection of whole reactor, and this technique also can be at loop line or open loop.In reactor, the surperficial vat liquor pouring of the add-on of treated waste and the three-dimensional arrangement of reactor and refuse needs relevant matches, only in this way could maximize the vat liquor pouring area on refuse surface, to ensure not having dead band.
Another advantage of present invention process is, the lower region place of reactor has spread a lot of pipeline.These pipelines can be used for the discharge with vat liquor that passes into of fresh air.These pipelines cover one deck filter screen, also stop refuse to enter as far as possible.Filter screen is cleared up by recoil method, and these pipelines can be interweaved.The leach liquor liquid of reactor lower region flowing, can produce some floating matters, these materials can better circulate, and especially these materials are comparatively hard and dry, preferably art breading purification.
On Technology basis of the present invention, the downstream of through reactor can also increase other machinery-biological treatments, and these Technologies may be used for purifying the vat liquor that this technique was used.Treated vat liquor can be put in reactor again and continue to use.
accompanying drawing explanation
Figure 1 shows that the schematic diagram of biopurification treatment system of the present invention;
Fig. 2-7 is depicted as the detail figure of design technology of the present invention.
Embodiment
Fig. 1 is the schematic diagram of biological cleaning treatment system.This biological purifying process is applicable to the moist biological waste containing Multiple components.Solid reactor " 2 " is for purifying organic waste, and its downstream is " 3 " of processing step-" 5 ", the mainly reclaiming process of aftertreatment technology and vat liquor.
According to Fig. 1, reactor " 2 " is a treatment chamber " 6 " elongated, and has a part vertically run through to see Fig. 2-Fig. 5 in treatment chamber " 6 ".The length " l " for the treatment of chamber is fixed value not, and its numerical value depends on and the size for the treatment of plant generally can be 20-30m.The height of reactor compartment is about 4-5m.In lower region, being the through part " 6 ' " for the treatment of chamber " 6 ", is a coarse right cylinder; Its top area " 6 " " can be rectangle (as Fig. 2), also can be trilateral (as Fig. 3), or oval (as Fig. 4).The cross bar " 7 " that the middle part for the treatment of chamber " 6 " has a level to run through, installing above of it is spun agitator " 8 " and is had paddle-shaped or the circulation device of blade-shaped " 9 ".Cross bar " 7 " rotates under the driving of driving machine " 10 ".
As indicated with 1, in one end of the treatment chamber " 6 " of reactor " 2 ", namely the tip position on the left side of figure is filler entrance " 11 ", and biological waste " 13 ", along the instruction of arrow " 12 ", is put in reactor.As long as some moist organic substances of so-called organic waste or biological heap, the residual biological garbage shares of main originates from life rubbish, foodstuff production industry, agricultural, garbage loading embeading or other biological rubbish.The composition of these biologic garbages has a great difference, so need organic loading, humidity and the initial temperature etc. of considering them in decontamination process.The other end of reactor " 2 " is positioned at the lower position on the right of Fig. 1, is the discharge outlet " 14 " of reactor, for material " 13 " discharge after treatment.Material " 13 " is in the reactor after a series of purifying treatment, and the direction along arrow " 15 " is discharged.
The inside of reactor " 2 " is " 17 ", and the packing height of material " 13 " is h f; The inside top of reactor " 2 " also has certain space to be air volume " 16 ".Generally, the loading level of material " 16 " is 2/3 of reactor " 2 " overall volume.
, there is several spray arm " 18 " at top in reactor " 2 ", and its effect sprays vat liquor " 19 " to material " 13 ".These vat liquors spray from spray arm " 18 " along the direction of arrow in reactor.At reactor " 2 " outward, feedwater piping " 20 " is arranged at its top, their connection control valves " 21 ", and by its regulation and control.Each spray arm " 18 " is connected on water service pipe " 20 ", and is connected with a control valve " 21 " between each spray arm and water service pipe, regulates and controls which spray arm spray vat liquor by by-pass valve control " 21 ".In device shown in Fig. 1,7 spray arms " 18 " are installed in reactor " 2 " inside, are uniformly distributed along the top in reactor.
In the bottom of reactor " 2 ", there is several lock chamber " 22 ", as shown in Figure 1, have four adjacent distributions.There is one deck screen cloth " 23 " between lock chamber " 22 " and reactor " 17 " inwall, fall into lock chamber " 22 " to prevent the material in reactor " 13 ".The mesh diameter of screen cloth " 23 " is d 1, its scope, at 6-12mm, is good with 8mm.Lock chamber " 22 " has two functions: first function collects vat liquor exactly, and vat liquor " 19 " enters the vat liquor " 19 ' " after fully contacting with material " 13 " in reactor and flows in lock chamber " 22 ", and is finally drained in manifold " 26 ".Between lock chamber " 22 " and manifold " 26 ", there is a vent pipe " 24 " and be connected with valve " 25 "; Lock chamber " 22 " second function passes into live gas exactly in reactor, and as shown in Figure 1, live gas is advertised in manifold " 29 " by pneumatic plant " 28 ", enters in pipeline " 31 " through by-pass valve control " 30 ", is finally drained into lock chamber " 22 ".In system, leach liquor flows to the function that reactor bottom also has back flushing screen cloth, and vat liquor flows through inside reactor " 17 " and enters lock chamber " 22 ", enters outlet " 14 " through overflowing wall " 32 " or overflowing edge.
Outside reactor, there is manifold " 26 " below, for being removed from lock chamber by vat liquor.Used leach liquor " 19 ' " enters pipeline " 34 " through manifold " 26 ", and pipeline " 34 " is connected with valve " 35 ".Vat liquor enters the purification process technique step 3-5 in downstream.These treatment steps comprise: interference separation device " 3 ", owing to being separated the insolubles settling in vat liquor, as bright in sand, stone etc., these materials are by filter screen " 23 ", the settling separated leaves interference separation device through transmitting device " 36 ", and the floating matter on liquid level such as plastics, wood chip or other materials are removed by removing slag device " 37 "; The vat liquor of separation and purification in interference separation device, through pipeline " 38 " and lift pump " 39 ", enter the anaerobic reaction step " 4 " in downstream, the design class of this anaerobic reactor is like marsh gas reactor, the organism be rich in vat liquor herein through the effect of meta-bolites biogas bacterium, biogas and biogas etc., and is degraded and purifies; Eventually pass the leach liquor that step " 4 " purifies to flow into through pipeline " 41 " in the aerobic purification reactor " 5 " in downstream, vat liquor enters aerobic step of reaction by anaerobic cleansing phase, fill with wind apparatus " 42 " and blast enough gas in reactor " 5 ", guarantee that the aerobic reaction of vat liquor completes.Common equipment unit can be applied in these three steps.
Vat liquor after above-mentioned steps purification, under lift pump " 45 " effect, leaves aerobic purification devices " 5 " through pipeline " 43 ", enters in tubing system " 44 ".Vat liquor is transported to reactor top by manifold " 44 ", enters spray arm " 18 ", complete the cyclic regeneration of leach liquor through independently liquid pushing tube " 20 ".
The unloading phase of workshop " 1 ", the vat liquor of application is a kind of common slightly acidic liquid, can apply the pure water of acidifying.Namely in reactor " 2 ", the pure water of application acidifying, as vat liquor, acts on material " 13 ", and aerobic reaction occurs.This technique is similar to hydrolytic action, namely uses the water decomposition soluble salt of acidifying.
The operating mode of solid reactor " 2 " is set forth as follows:
Continue or discontinuously material " 13 " poured in reactor " 2 " by entrance " 11 ", the organic substance that material " 13 " is a kind of humidity, mainly above-mentioned biologic garbage.The amount of pouring into of material " 13 " is 2/3 of inside reactor height " h ", and remaining space is the air volume " 16 " at top.The visible Fig. 2 of detailed diagram-Fig. 5, the total width on the surface " 46 " of material " 13 " is B, and vat liquor " 19 " sprays from reactor head.Therefore, in the reactor, in order to avoid the minimizing of the topside area of material " 13 ", reactor design can become cross section be the rectangle of Fig. 2, the trilateral of Fig. 3 or the ellipse of Fig. 4.
Spray arm " 18 " sprays vat liquor " 19 ", and vat liquor mixes with material " 13 " can make the lixiviate such as dissolved organic matter, inorganics, solubility lipid acid in material " 13 " out.In reactor, material " 13 " needs spinning lasting under agitator " 8 " effect or circulating discontinuously, and this point is extremely important.In order to mix material " 13 " more fully, spin the paddle device " 9 " that agitator " 8 " has paddle-shaped or blade-shaped.Meanwhile, this stirring it also avoid vat liquor flowing away straight along horizontal direction or vertical direction, and the vat liquor caused can not contact completely with material " 13 " and form dead band.As shown in Figure 1, paddle device " 9 " next-door neighbour of several paddle-shaped or blade-shaped or overlap assembly, therefore material can circulate with disc format.Cross bar " 7 " rotates under the driving of driving machine " 10 " in addition, makes the material in reactor along the direction slowly movement of arrow " 48 ".Finally, material " 13 " stays for some time in the reactor, general 4-8 days, discharges reactor from outlet " 14 ".
In this purification process technique, continue or be interrupted pouring vat liquor while, also need inject fresh air " 27 ".In reactor, pass into fresh air by the lock chamber " 22 " of reactor bottom, with releaser " 13 " by heat release self-heating, aerobic reaction occurs and reaches purification object.Under the microorganism species effect be applicable to, and introduce strong gas explosion technique in closed reactors, organic waste generation aerobic bioreactor is degraded, and reaches decontamination effect improving.In reactor, the top of material " 13 " is the gas space " 16 ", is discharged by gas from gas discharge outlet " 50 ", thus ensure that continuous circulation and the renewal of the gas in reactor by suction pump " 49 ".In reactor, by decompression, headspace is arranged outward, to guarantee air volume " 16 " always for aerobic environment.
In the reactor, longitudinally continue or flow forward discontinuously, different material compositions, residence time in the reactor also can be different for material " 13 ".Such as, relatively fresh, for the material of process is added in reactor by inlet " 11 ", finally get rid of the material after purification from relief outlet " 14 ", all stage lasts 4-8 days.Certainly, the whole length " l " of reactor, also determines the purge amount of organic waste.
Although do not provide a lot of concrete details, in reactor, some test sets should be added.The various parameters of refuse to be clean, as: one-tenth is grouped into, temperature, humidity etc. all need to detect, and will detect the conveying of vat liquor and air in addition.According to concrete treatment process, how different the vat liquor flow velocity of the spray arm " 18 " of arranged adjacent assembling also has, to ensure that the material composition in refuse can leach completely.Lock chamber " 22 " is arranged on the bottom of reactor, inputs fresh air " 27 " in reactor, and in order to ensure the complete of the aerobic degradation of material " 13 ", the input flow velocity of fresh air " 27 " also can be distinguished to some extent.Meanwhile, because the performance of refuse is different, the technique of material mixing also needs regulation and control.Increase the surface-area of organic waste, the aerobic degradation process of refuse can be improved, because the surface-area of refuse is larger, the immersion Zn of vat liquor " 19 " can be improved.According to aerobic degradation degree, room lab scale by experiment, can determine the amount that vat liquor adds.In addition, improve the temperature of vat liquor, also can promote the oxidative degradation of refuse.In the inside " 17 " of reactor " 2 ", also should assemble appropriate test set, by the degree that presets with detect numerical value and regulate and control reaction process in reactor further.
Lock chamber " 22 " surface coverage of next-door neighbour's assembling has screen cloth " 23 ", and the effect of screen cloth " 23 " mainly prevents material " 13 " from entering in lock chamber " 22 ", by the diameter " d of the eyelet of screen cloth " 23 " as much as possible 1" impact.But after screen cloth " 23 " application for a long time, need cleaning impurity and obturator, cleaning application backwash operation.Liquid " 19 ' " flows in lock chamber " 22 ", and after valve-off " 25 ", the liquid in lock chamber " 22 " constantly gathers, and liquid level constantly rises.In addition the vat liquor after purifying also can reflux return in lock chamber " 22 " to increase the amount of liquid in lock chamber.This process as shown in Figure 4 and Figure 5, open by the valve " 53 " that liquid pushing tube " 52 " connects, and vat liquor flowed back in manifold " 51 " and pipeline " 43 " " 44 ", finally turns back in lock chamber.Liquid constantly flows into lock chamber, and last liquid level " 33 " reaches the height overflowing wall " 32 ".Open gas blower " 28 ", to increase the mobility of liquid, strengthen the souring to screen cloth " 23 ".To this backwash operation of screen cloth " 23 ", only can be implemented on a lock chamber, also can be implemented on specific two or more lock chamber.By control valve and suction pump, by fluid accumulation to the pre-lock chamber implementing back flushing, also the liquid of contiguous lock chamber can be evacuated to this lock chamber.Shown in Fig. 1, if such as implement backwash operation at the second lock chamber, the liquid of the first lock chamber and the 3rd lock chamber can be discharged, in suction to the second lock chamber, simultaneously to air blast in the second lock chamber, complete backwash operation.
Certainly, in backwash operation process, liquid level " 33 " constantly rises, and when exceeding screen cloth, the material " 13 " of reactor bottom can be made to suspend wherein.But this does not affect, and the material suspension of bottom gets up more to contribute to the mixing of material, especially hard or very dry material.
Spray the situation of the amount of vat liquor " 19 " and the amount of input fresh air " 27 " and material circulation, as lasting circulation or interruption circulation etc., all affect the purifying treatment process of material " 13 ".The concrete enforcement of technique is optional uses following parameter: in reactor, the add-on of vat liquor can add about 0.5-2m by PMT (Per metric ton) refuse every day 3; Agitator runtime is unlatching 5-60min per hour, and rotating speed is 1-2rpm.
Figure 2 shows that the sectional view that a kind of inside reactor designs.This design can make the width of the upper surface of material " 46 " maximum as far as possible, and sour jujube sample agitator " 8 " can fully make material circulate simultaneously.Vat liquor " 19 ", after material, becomes liquid " 19 ' ", the lock chamber " 22 " bottom inflow reactor.In addition also have aerating apparatus, live gas " 27 " is blasted in reactor, than the aerobic degradation reaction ensureing material " 13 ".
Certainly, vat liquor and fresh air can simultaneously in injecting reactors.Technological design as shown in Figure 3, only has fresh air " 27 " inlet, does not have extra vat liquor liquid dispensing apparatus.
Fig. 4 is backwash technique.The liquid level of liquid is " 33 ", exceedes the height of screen cloth.Liquid washes away in screen cloth process, and material " 13 " floats in liquid, under the effect of agitator " 8 ", can mix material further.In this mixing process, the material height in reactor may increase, and this there is no disadvantage to whole process.
As shown in Figures 2 and 3, fresh air injects lock chamber " 22 " by the pipeline " 23 " of band valve " 30 ", enters material " 13 " through screen cloth " 23 ".Microorganism aerobic breakdown process and aerobic degradation process all need fresh air.Gas finally accumulates in the upper space " 16 " of reactor, discharges reactor from venting port " 50 ".
Figure 5 shows that backwash operation.After valve " 53 " is opened, liquid flows into lock chamber through pipeline " 52 ", simultaneously aeration, to strengthen flushing dynamics.And the backwash technique shown in Fig. 4, do not add aeration, valve " 30 " is closing condition.
The optimization design of the relevant device of technique of the present invention and application, will hereafter be further elaborated.
As shown in Figure 1, in the position of waste inlet " 11 ", partition wall " 55 " has been installed.The object of partition wall " 55 " is, prevents the refuse that just injected through the minimum material surface " 46 " of resistance, flows directly to the position of relief outlet " 14 ", and fail to circulate in the reactor and purify.The refuse of fresh injection, along partition wall " 55 " inflow reactor, along the direction of arrow " 56 ", circulates in the reactor.
Sometimes, in order to more be conducive to the purification of material, need in reactor to maintain certain temperature.Can at the L of reactor afterbody 1part is heated, L 1for the 3/1-1/4 of total reactor length.Vat liquor after separation and purification, through pipeline " 43 ", enters in pipeline " 57 ", pipeline " 57 " is connected with a heating unit, as thermophore " 58 ", and the liquid heat that can will flow through.Liquid after heating enters spray arm through pipeline " 20 ' ", is sprayed into reactor afterbody L 1part.Due to the inflow of the liquid of these heat, the temperature in reactor can be raised rapidly.Vat liquor after separation and purification also can be passed through manifold " 44 " and flows to above reactor, enters in reactor through liquid pushing tube " 20 ".Last liquid pushing tube in Fig. 1 is pipeline " 20 ' ".
Another improvement of present invention process is exactly by inlet " 11 ", continue or be interrupted add active sludge or excessive mud.Containing aerobic microorganism flora active sludge add, the Degradation and Transformation of organic waste can be promoted.Arrow mark " 59 " of visible Fig. 1 of interpolation of active sludge.Verified in this technological experiment, microorganism species be added with the purifying treatment helping refuse.Microorganism species also finally can join in reactor by aerobic filter treatment unit or biological vat liquor purifier apparatus equipment.At outlet " 14 " place of reactor, Commodity flow " 15 " enters affluent-dividing " 15 ' ", and the material after Partial cleansing can enter pipeline " 60 ", is transported to the position of inlet " 11 ", along the direction of arrow " 62 ", the material after purification is put in reactor again.Owing to containing microorganism species in the material after these purifications, therefore cycle applications is very necessary.
In Fig. 2-Fig. 4, on drive shaft " 7 ", whipping appts " 8 " is housed radially, and each whipping appts is furnished with adamantine paddle.As shown in Figure 5 and Figure 6, in order to produce agitation effects, to reach better mixed effect, the change turning direction that agitator can also be interrupted.In experiment, agitation effects better, also need to improve whipping appts, paddle can be designed to slight curving knife-like, as shown in Figure 5 and Figure 6, intercept angle is in " x ".Paddle is designed to flaabellum shape, sense of rotation is counterclockwise, seemingly can better play mixing effect, but if containing plastics film or banded material in refuse, these materials will be wound on paddle, so this alr mode and design will highlight discomfort.In order to make agitator be applicable to many kinds of substance, driving stem " 7 " needs forward and reverse interval to rotate, and the assembling of agitator also will slightly be tilted.And the contact friction of agitator and material " 13 ", the dirt on agitator can also be scraped off and play cleaning action.
In addition, the technological design shown in Fig. 6, whipping appts " 8 " can also play the effect of cleaning one such trash screen " 23 ".At the end of hard paddle " 8 ", be to load and unload parts " 63 ".This can load and unload part can for scraper sample.Go out at opening " 65 ", a fixture is installed, when needing " 63 " to be assembled to paddle end, only need operate herein.In addition, the container " 6 ' " shown in Fig. 6 is for cylindrical, and agitator " 8 " is not assemblied in the middle position of container, but position on the lower.The reason of such design is, the radius R of agitator 2need the radius R of container 1little, but after fit on scraper " 63 ", have needs can be applied on screen cloth " 23 ", the inwall of container can not be damaged simultaneously.
Fig. 7 is the longitudinal direction figure of the driving stem " 7 " of agitator.What agitator " 8 " tilted slightly is assemblied on cross bar " 7 ".When drive shaft " 7 " rotates, this trim designs slightly tilted of agitator " 8 " can produce the effectiveness of similar water screw.Such as, when rotating shaft " 7 " is counterclockwise to rotate, material " 13 " can move along the direction of " g "; And rotating shaft " 7 " is when rotating in a clockwise direction, material " 13 " just moves along the direction of " h ".Therefore the sense of rotation difference of rotating shaft can cause agitator mixing direction different, thus make the migration of material in reactor or after move.For Cucumber purification, this design is more conducive to mixing of refuse " 13 " of refuse " 12 " and the reactor newly injected.
