Background technology
Known a large amount of machinery, chemistry and biological method and corresponding reactor are used for purifying liquid waste.When biology is purified liquid waste, waste water to be clean contacts with the microorganism of aerobic or anaerobism, in the situation of aerobic microbiological, the organic dirt that is included in the waste water mainly resolves into carbonic acid gas, biomass and water, and mainly resolves into carbonic acid gas and methane in the situation of anaerobion.At this, microorganism obtains endogenetic energy (metabolism).Because the decomposition course of anaerobism provides seldom special energy, so the synthetic of the biomass of anaerobism lacked much than the synthetic of aerobic biomass.
Because high cost of energy, implement biological purification method for effluent by anaerobion more and more in nearest for some time, because when anaerobic waste water purification, oxygen introduced in the bio-reactor and needn't consume a lot of energy, in this purification, produce be rich in energy, can be used for obtaining the biogas of energy subsequently, and produce significantly less excess sludge.
According to kind and the form of employed biomass, the reactor that is used for anaerobic cleaning of waste water is divided into contact sewage sludge reactor (Kontaktschlammreaktor), UASB-reactor, EGSB-reactor, fixed bed-reactor and thermopnore-reactor.
When microorganism is attached to the fixing solid support material in position and microorganism and sticks on the vectorette material that can move freely in fixed-bed reactor, in UASB and EGSB reactor, insert microorganism with so-called pill form in flowing bed reactor.Be different from UASB (upflow anaerobic sludge blanket process)-reactor, EGSB (expanded granular sludge bed)-reactor is higher and have obviously less basal plane in the situation of same volume.
In UASB and EGSB-reactor, by an input tube in the reactor lower part zone continuously with waste water to be clean or a kind of by waste water to be clean and from the output tube of anaerobic reactor the mixture of waste water composition that discharge, that purified flow to reactor, and guiding is through being positioned at Sludge Bed input tube top, that contain the microorganism pill.
When decomposing organic compounds from waste water, microorganism forms and to contain the especially gas of methane and carbon dioxide (being also referred to as biogas), described gas partly accumulate on the microorganism pill with the form of small bubbles and partly with small bubbles form freely to rising.Because the bubble that gathers, the proportion of pill descends, thus pill in reactor to rising.For the biogas that makes formation and the particle of rising separate with water, on middle part and/or the top of reactor the separator that some mostly are greatly the gas hood form is set, the biogas that forms air cushion is gathered in the below of these separator top boards.The water that discharges from gas and microorganism pill, purify is discharged via overflow port to rising and in the upper end of reactor in reactor.This method and corresponding reactor for example are documented among the EP 0170332A and EP 1071636B.
It is particularly important that the waste water that flows to reactor by input tube in aforesaid method distributes to being implemented in mud pill in the reactor, water in reactor and the waste water good mixing of input on reactor cross-section uniformly.In order to satisfy this demand, advised being furnished with in a large number the reactor of corresponding delivery distributer.
By the known a kind of bio-reactor with reaction vessel of EP 0539430B, this bio-reactor has the conveying-entrance system that comprises at least one input tube in the lower end of reaction vessel, it basically is the conical tripping device of arranging by one and separates with the reaction chamber that contains the microorganism pill, wherein, tripping device extends in whole reactor cross-section.At this, the at least part of tangent ground of the taphole of input tube is directed and at tripping device at least one radial gap is set, it forms by two edge strips radially, that mutually overlap with certain vertical range, wherein, described at least one radial gap is formed on the connection between conveying-entrance cavity and the reactor cavity.The orientation of taphole He at least one radial gap by input tube, should realize the water inputted to the longitudinal axis annular of reactor flow and layout by radial gap especially should prevent solid intrusion conveying-entrance system turning off reactor after.But this reactor and the method by its operation have a lot of shortcomings.
Since fill 100% reactor cross-section, the tripping device between conveying-entrance system and reactor cavity, so be included in solids accumulation in the waste water of input in the inside of conveying-entrance system and do not arrive in the reaction chamber.But be deposited in conveying-entrance system, that is, the solid below conical tripping device just is difficult to isolate from reactor.In addition, for separate solid from reactor, must the off-response device.In addition, when especially calcium salt content is high in waste water to be clean, calcium salt is deposited on the pill in reactor cavity, therefore a part of microorganism mud pill that deposits calcium salt has high proportion, so these pills deposit and be deposited in the lower end of the conical tripping device in the reactor wall zone in reactor.These settlings also only could separate from reactor in very large situation about expending.In addition, because the settling on the reactor wall has reduced the effective diameter of reactor, so reduced effective reaction volume.
For these reasons, need to improve aforesaid for purifying the high waste water of calcium salt content, such as the reactor of the waste water of the dirt that deposits of from paper industry, discharging, also can contain the forms such as paper wadding simultaneously.
The utility model content
Therefore, technical problem to be solved in the utility model is to realize the little active pill of optionally output.At this, particle is interpreted as into granular microorganism mud.
Press the utility model, this technical problem is by solving like this, that is, at least one input tube for delivery of fluid passes into the lower end of funnel.This is funnel shaped, the single cone that narrows down especially downwards or the reactor bottom of bipyramid form guaranteed solid that settle down from reactor top, hyperbaric drop to always funnel the tip and can export from here.Thus, can avoid reliably throw out be gathered in the input area, cause and form the dead band and cause reducing of reactor effective cross section.
Therefore, advantageously, settling is set in the lower end of funnel discharges part.
Because infusion fluid is compared the higher lift velocity in remaining reactor part, so only have some pills heavier, deposition just can remain on the reactor bottom.Other pills that lowering speed is less than the lift velocity of infusion fluid remain on the so-called pill bed.
If discharge pill mud by discharging part at the settling of funnel lower end now, then this pill mud only contains the seldom microorganism active material of amount.
In addition, can reactivate the pill that has been settled out but still contain the microorganism active material with the liquid from waste water to be clean by inputing to small part.
Because good nutriment supply causes and again produces gas.
Being attached to gas on the pill at this forms corresponding buoyancy and therefore pill is drawn and get back in pill bed or the Sludge Bed.Therefore pill is classified by biological activity.
At this, also only have heavier, almost do not have bioactive pill to be retained on the funnel lower end, these particles can be discharged part by settling and be discharged.
At this, reactor bottom also can be made of a plurality of funnels with settling discharge part and input tube.Reactor and funnel can have a cross section circle or that corner angle are arranged.
For the liquid of inputting can be brought into play the effect of having stated as far as possible all sidedly, at least one input tube for delivery of liquid should pass in the funnel at the lower-most point place as far as possible.
If only a delivery conduit passes in the funnel, can be enough according to the characteristic of waste water and size and the structure of reactor.Yet to good distribution waste water to be clean advantageously, many input tubes preferably pass in the funnel in funnel surface evenly distributedly usually.
In order to produce enough lift velocity, the input tube that is arranged at least lower-most point place in the reactor should make progress liquid, and preferred vertical up sprays in the reactor.
For can be as far as possible all sidedly with heavier, precipitation and do not have activated particle output, settling is discharged part and should be passed in the funnel at funnel lower-most point place.
Can be advantageously at this, at least one settling discharges that part is laterally discharged settling from reactor and/or at least one settling discharged part settling is discharged from reactor downwards.
In the settling discharge part of side direction, cross by the deposition logistics of settling discharge part output and the liquid stream of carrying by input tube, and in the settling discharge part of sensing downwards, discharge the deposition logistics of part output and flow oppositely mobile by the liquid that input tube is carried by settling.In both cases, realize the well blend of stream, therefore can realize in enough modes the described selection to pill.
Aspect method, importantly, liquid is sprayed into the lower end of funnel by at least one input tube.
At this, can be advantageously when pill precipitates consumingly, settling is discharged part and is opened wide always.
But in most situation, should be enough be that settling is discharged part and only opened in one section definite efflux time interval.
At this, can be advantageously in order to control the efflux time interval, the scope of the scope that the measurement settling deposits in funnel and/or the sediment yield of from funnel, discharging.
For selecting constantly pill, should pass through constantly infusion fluid of input tube.
Very advantageously, can regulate by structure and/or process control the share (ash content) of inorganic materials in the settling.
But mostly enough in the situation is only to carry liquid by input tube within one definite period.For example this scope in the settling deposition can be carried out above after a certain amount of.
If have enough empirical values or provide simple operational conditions, so also can periodically open input tube.
Because the selection of pill is particularly important when it is discharged especially, so input tube should and/or be opened in the process before settling output.
Select pill for the lift velocity by infusion fluid, the kind of liquid is not quite important.Therefore, liquid is made of fresh water, the to be clean or waste water that purified or their mixture at this.
Select pill to require liquid to be consisted of by waste water to be clean at least in part according to the biological activity of pill.
Description of drawings
Below further set forth a plurality of embodiment of the present utility model.In the accompanying drawings:
Fig. 1 be the schematic longitudinal section of reactor and,
Fig. 2 and 3 is longitudinal sections of different funnels.
Embodiment
Bio-reactor shown in Figure 1 comprises a reaction vessel 1, the middle part of this reaction vessel becomes cylindrical with upper design and its bottom 2 is tapered with being the bipyramid bodily form downwards, wherein, the top 3 relative level masks of bipyramid have one than the less gradient in the bottom 2 of bipyramid or less angle.
Two separators 10,11 that have respectively a plurality of gas hoods 13 are positioned at middle part and the top of reaction vessel 1.In practice, each separator 10,11 is comprised of multilayer gas hood 13; But each separator 10,11 only illustrates respectively only one deck gas hood 13 for the sake of simplicity in this Fig. 1.
Above top separator 11, there are some overflow ports 12 that the water that purified is discharged from reactor 1.
Be provided with gas separation unit 14 at reactor 1, this gas separation unit 14 is connected with two separators 10,11 by conduit 15.In addition, sedimentation pipe 8 leads to the bottom of reactor 1 from the bottom of gas separation unit 14.
In addition, bottom at reactor 1, namely, exist settling to discharge part 7 and input tube 6 in the bottom 2 of bipyramid, wherein, discharging part 7 by settling can discharge from reactor 1 and can introduce liquid for wash reaction vessels 1 bottom by input tube 6 with solid or by the suspension that solid and liquid consist of.At last, a plurality of other distribution-input tubes 9 that lead to each deflection device 5 are set in reactor 1, wherein for for the purpose of clear, in Fig. 1, a few only are shown.In addition, in reactor 1, be provided with distribution-input tube 9 that another passes into sedimentation pipe 8 lower ends.
When reactor is worked, waste water to be clean via reaction vessel 1 wall of distribution-input tube 9 by being arranged in bipyramid top 3, unshowned slit introduces reaction vessel 1 and by in this wise deflection of deflection device 5 so that the waste water of input be in reactor in, the media depth that is comprised of waste water, microorganism pill (representing with point in Fig. 1) and the small bubbles of part purification mixes.
The input divider 4 of waste water from reaction vessel 1 of introducing upwards flows lentamente, until it arrives at the fermentation zone that contains microorganism mud pill.Be included in the organic dirt that the microorganism in the pill will be included in the waste water and mainly resolve into methane and carbon dioxide gas.By the γ-ray emission small bubbles that generate, wherein larger small bubbles come off from pill, and foam by medium with the form of bubble, and small bubbles remain adhered on the mud pill.Those pills that are attached with small bubbles and therefore have the proportion less than other pill and water rise in reaction vessel 1, until those pills arrival bottom separators 10.
Small bubbles are gathered in the gas hood 13 and below gas hood 13 top boards and form air cushion freely.The gas of in gas hood 13, assembling and the pill of carrying secretly on a small quantity and water for example through being present in gas hood 13 distolateral, export from gas hood 13 in unshowned hole and be guided in the gas separation unit 14 via conduit 15.
The microorganism pill of water, rising and in bottom separator 10, also do not have separative bubble in reaction vessel 1, to continue upwards to rise until the separator 11 on top.Because hydrostatic reduction between bottom separator 10 and top separator 11, the last less microorganism pill of small bubbles from arrive top separator 11 comes off, so the proportion of pill increases again, and pill is to decline.Remaining bubble is collected in the gas hood 13 of top separator 11 and again transfers in the effuser at the distolateral place of each gas hood 13, and gas is introduced the gas separation units 14 via conduit 15 from this effuser.
The water that has now purified continues to rising from top separator 11, until it is discharged from reactor 1 and led away by a water shoot through overflow port 12.
In gas separation unit 14, gas separates with the microorganism pill with remaining water, wherein, is recycled in the reaction vessel 1 via sedimentation pipe 8 by the suspension of pill and waste water composition.At this, the outlet of sedimentation pipe 8 passes on the height of deflection device 5, wherein, is mixed with the waste water that flows to reactor 1 by distribution-transfer lime 9 by suspension pill and waste water composition, that draw back, restarts afterwards circulation.
Waste water to be clean or fresh water can be flowed to sedimentation pipe 8 continuously or discontinuously by demand by distribution-transfer lime 9, be drawn suspension and therefore settlement prevention pipe 8 obstructions of getting back in the reactor 1 by sedimentation pipe 8 with dilution.
According to the source of the waste water that passes through distribution-transfer lime 9 input reactors 1, waste water more or less contains solid.The solid packing and the calcium salt that for example contain very large concentration from the waste water of paper industry.
After the waste water that contains solid was directed to deflection device 5 by distribution-transfer lime 9, this waste water rose, and after this waste water left deflection device 5, waste water was to rising to columniform reaction vessel part.Be included in solid in the waste water, bottom line puies forward hyperbaric share and drops to after leaving deflection device 5 in the downward tapered bipyramid, and be gathered in the lower tip part of bipyramid bottom 2.
In addition, after waste water rose to the Sludge Bed district, a part that is included in the calcium salt in the waste water was separated out at the mud pill.Thus, the part of mud pill surpasses critical proportion and therefore sink to also being gathered in equally the lower tip part of bipyramid bottom 2 from Sludge Bed.
Because geometrical shape and the layout of deflection device 5, the pill that falls from the top down can not be deposited on the deflection device 5, and from the outside surface landing of deflection device 5, and be gathered in equally in the lower tip part of bipyramid bottom 2.
Discharge part 7 by settling, the settling that is gathered in reactor 1 lower tip part place is discharged from reactor 1 continuously or in bulk by demand.
In addition, can insert the liquid into continuously or in bulk in the bottom 2 of bipyramid by demand equally by the input tube 6 in bottom 2.The liquid of carrying for reactor 1 by input tube 6 can be waste water to be clean, the waste water of recirculation from reactor, fresh water or their mixture.
Shown in Fig. 2 and 3, input tube 6 and settling are discharged part 7 and are passed into reactor cavity at funnel lower-most point place.Although also can be other shape, be consisted of by a downward tapered circular cone respectively at this funnel.Only importantly, the reactor wall of inclination is with the direction guiding of settling towards vent pipe 7.
At this, liquid is vertically upward introduced in the reactor by input tube 6.
In Fig. 2, settling is discharged part and is passed into from the side in the funnel tip, in order to the deposition logistics when discharging is crossed with ascending liquid from input tube 6.
Different is that settling is discharged downwards in pressing the embodiment of Fig. 3 with it.This means that the liquid of settling to be discharged and input tube 6 inputs oppositely flows.
The result so that liquid and settling mix well.
Lighter, also unprecipitated pill since the lift velocity of the liquid of carrying by input tube 6 upwards direct in the pill bed.Only the pill of precipitation remains on the funnel tip and can discharge part 7 by settling and discharge.
In addition, causing by the transport wastewater of input tube 6, the pill of partly precipitated is activated.The relevant gas that produces causes being attached to the bubble on the pill with it, and these bubbles are given these pill buoyancy.Only have heavier, almost do not have pill bioactive, that discharge part 7 outputs by settling to remain on the funnel soleplate.
The result has reduced sedimental discharge, because do not have the activated pill mud can be optionally separated, and active pill mud be retained in the system.This has improved the efficient of wastewater treatment significantly.
