The present invention relates to be used for the bio-reactor that water purifies, described reactor comprises that the cross section is circular or oval-shaped container portions substantially, described container portions is provided with water to be clean with inlet device with purified waste water and used outlet unit, be equipped with on it in the described container and can form biomembranous solid support material, described container further is provided with the device that is used to supply the required air of aerobic scavenging process.
The invention still further relates to the method for in bio-reactor, water being carried out biopurification, described bio-reactor comprises that the cross section is circular or oval-shaped container portions substantially, described container portions is provided with water to be clean with inlet device with purified waste water and used outlet unit, be equipped with on it in the described container and can form biomembranous solid support material, described container further is provided with the device that is used to supply the required air of aerobic scavenging process.
Background technology
For the biopurification such as water such as waste water, described water flows through reactor, wherein microorganism to be used for the water ballast impurity conversion be harmless final product, as carbonic acid gas, inorganics and water.In biological water purified, described microorganism can combine with himself (being biomass) or non-biodegradation product (for example heavy metal).Can under aerobic or oxygen free condition, purify.The various bio-reactors that are used for purification of waste water of previously known are as trickling filter, biological drum (rotating biological contactor), fluidized-bed reactor, fixed-bed reactor and moving-burden bed reactor.A kind of bio-reactor of previously known comprises solid support material is delivered to a process that the surface energy of described solid support material grows the microorganism of microbial film form.
A kind of typical biomembrance process (fixed-bed reactor) is based on filling described purification reactor with the solid support material of filler particles form, and described filler particles is applicable in described method and is maintained fixed.By realize being present in the biomembranous oxidation on the surface of described filler particles to described reactor supply air from the bottom.The advantage of this method is, because described microbial film has big growth area, so the per unit reactor volume has a large amount of biomasss.The shortcoming of the so-called fixed bed of this class is, described bioprocess can stop owing to biomass (mud) or other particulate matters, and the place in water and living microorganism loose contact forms non-active region in described process.Another problem is to be difficult to clear up, and this is because be difficult to touch described reactor below, if described bio-reactor blocking just must empty whole bio-reactor to clear up.
Go back the known organism embrane method at present, wherein said solid support material keeps motion in described method, referring to for example US 6,126,829, US 5,458,779 and US 5,543,039.The advantage of such moving-bed type bioreactor is, basically eliminate the obstruction of solid support material and the formation of non-active region.Part has prevented the surface and the collision of other carrier elements of described carrier element.Yet shortcoming herein is that the ability of described method is subjected to suitable restriction, this is due to the fact that, that is, and and for the carrier element with unrestricted reactivity is set in water to be clean, needing low especially compactedness, for example is about 30%～70% magnitude of empty reactor volume.Therefore, the ability of removing impurity is lower than the fixed-bed reactor that have same volume and fill with the same vehicle material, and this is because described fixed-bed reactor have higher carrying capacity.
The raising compactedness will cause the increase of oxygen depletion, and this will require more powerful compressor, and described bioprocess may be further disturbed in strong thus air-blowing.Improve described compactedness and will cause the formation of fixed bed, and because described carrier can be because of the biomass blocking, thereby stopping of described bioprocess caused.In addition, if increase the compactedness in the moving-bed type of reactor, to need a large amount of air and energy to keep described carrier movement, thereby obviously increased the mechanical stress that is applied on the microbial film, cause described microbial film to peel off from described carrier surface, thereby cause stopping of described bioprocess, this is disadvantageous.Another main drawback is that described reactor must be provided with safety net, so that described breather and carrier element are separated.Described net must have certain mesh size, so that stop carrier element by its opening.This has hindered per unit volume to have the use of larger area small size carrier, will weaken the air supply and may cause described opening blocking because correspondingly reduce the mesh size of described net.
Summary of the invention
An object of the present invention is to provide a kind of through improved bio-reactor, described bio-reactor can be eliminated the shortcoming of fixed-bed approach and moving bed process, can realize per unit volume than the higher impurity treatment rate of the reactor of previously known, thereby reduce the purification cost.For realizing this purpose, bio-reactor of the present invention is characterised in that, the cross section of described container portions is circular or oval substantially, be provided with the water out device at described container portions, make described container portions in scavenging process, be full of water substantially, fluid supply apparatus is configured on the described wall of a container, and described reactor comprises control device, described control device is used to move described fluid supply apparatus, make described carrier, water and the fluid that contains reactant gases thus around the kernel of section that passes described container substantially realize rotatablely moving around rotation centerline, described control device is applicable to alternatively realizes stopping using of described fluid supply apparatus in the time of needs.
According to idea of the present invention, in described scavenging process, described container portions keeps being full of substantially that water is arranged, make reactant gases (for example form of bubble) move with water and carrier, thereby make described bubble have long operating range and time, therefore make described carrier can have high compactedness, this compactedness is preferably more than 70% to about 100%, and this is different from the moving bed type scheme of compactedness within 30%～70% scope of the instruction solid support material of previously known.The compactedness of described solid support material is directly proportional with the usefulness of bioprocess, that is, and and the compactedness (m of solid support material in reactor
2/ m
3) high more, its purification efficiency is high more.In the solution of the present invention, the amount of solid support material also can obviously be less than 70%, for example is less than 50%.The compactedness of described solid support material depends on the oxidation capacity and the loadings of described reactor.Carrier can keep the desired size that rotatablely moves and the plastic component of shape to constitute by having.When using reactor of the present invention, found in the aerobic process, air filled cavity in described reactor than in the reactor that uses at present, keeping the obvious longer time, this is because described bubble rotates considerable time with described solid support material and water, so that microbial film can carry out more effective oxidation.Simultaneously, described air filled cavity breaks and is littler air filled cavity, and this is that another helps oxygen by the factor that is passed in the air in the water.This has reduced the demand to air, therefore than activated sludge, fixed bed and moving bed type method, has reduced running cost.
On the other hand, method of the present invention is characterised in that, in the bio-reactor that described method is used, the cross section of described container portions is circular or oval substantially, described fluid supply apparatus is configured on the described wall of a container, described method comprises to described container supply raw water, make described container in scavenging process, fill water substantially, and control described fluid supply apparatus, make described carrier, water is realized rotatablely moving around the rotation centerline of the kernel of section that passes described container substantially with the fluid that contains reactant gases thus constantly or off and on.
The solution of the present invention makes microbial film have big growth area, because described carrier, water and the fluid that contains reactant gases be around the circular frequency rotation with constant of the rotation centerline of single part, described reactor can not form the dead zone.Various piece in bio-reactor still can be moved with different directions.
In the bio-reactor of rotation type of the present invention, carrier element is with an identical direction rotation, this clearly makes a distinction the bio-reactor of rotation type of the present invention itself and the moving bed type method of prior art, in described moving bed type method, carrier element is disordered motion in water, makes only can adopt relatively low compactedness.If described compactedness surpasses 70%, described moving bed type method will change fixed-bed type into, and this is that the result causes the obstruction of bio-reactor because the particle of described disordered motion will collide mutually with higher frequency, and this will make its motion stop.Particularly advantageous characteristics of the present invention is, described container portions is applicable to fills water in operational process, so required energy minimum of rotating carrier material, and described bubble rotates around rotation centerline together with mode the same with described solid support material and water, therefore when for example comparing with the moving-bed scheme of previously known, its operating range and time are doubled, described moving bed type scheme relates to the utilization of liquid level, and wherein air filled cavity is to migrate to the air volume that is positioned at described container top by the air entry point that is usually located at container bottom substantially.In this disclosure, term " is full of water " substantially in order to refer to that the fluid that the described fluidic supply of water as many as that described container is equipped with can make described carrier, water and contain reactant gases is rotated motion around the rotation centerline that passes the kernel of section of described container substantially.Find through overtesting, the amount of described water should surpass described diameter of section at least about 85%, be preferably about 100%.Be less than in the water yield under about 85% the situation, described method become the moving bed type method (wherein the compactedness of carrier must be less than 70% so that described method carried out), rather than change fixed-bed type into.Compactedness that described moving bed type scheme employing is relatively low and carrier element are in order to protect described microbial film to avoid because carrier element collides the breakage that is caused each other repeatedly by the Another reason of specific mode moulding.The solution of the present invention preferably adopts semifixed bed scheme, wherein said solid support material is made of a plurality of carrier elements that have about 100% compactedness in described container portions, therefore, around the medullary ray rotation time, described carrier element does not have relative movement each other substantially, but rotates with the form of incorporate substantially carrier bed.Therefore, the composition of described carrier element also is unlike in the moving bed type scheme so crucially, in described moving bed type scheme, must consider carrier element relative movement each other.Because by the rotatablely moving of the best, method of the present invention does not need a large amount of fluids to make described carrier persistent movement, so the solution of the present invention allows to adopt softer fluid feed, so will be not can disturbance bacterium on the surfaces of carrier materials.See that from biological angle crucial is that described microbial film can mechanically not washed out from described carrier surface because of bubble.Because described fluid supply is positioned at periphery, and carrier not motion each other, (perhaps mainly due to the high compactedness that surpasses 70%) and can not be subjected to mechanical stress thus.On the other hand, excessive mud or dead biomass can be thrown to outside the described bio-reactor according to the law of inertia, if in rotatablely moving, biomass begins to assemble to starting point, and density also begins to increase, consequently, the carrier that is present in the center begins to move to periphery gradually, and biomass is positioned at periphery, and according to the law of inertia, it can be discharged from described bio-reactor.
The compactedness of solid support material is the term that is used to refer to the required space of solid support material with respect to the volumetrical amount that is in the container portions under the vacant condition, rather than refers to the volume that water is shared.When adopting a plurality of carrier element, described 100% compactedness is meant the situation in the space of the described container portions of can not more more carrier element being packed into.

Be provided with solid support material 3 in described container portions, microorganism can be deposited as microbial film on described solid support material 3.Described solid support material can for example be made of single carrier element, perhaps carrier element or a plurality of isolated vectors element by a plurality of mortise constitutes, thus, under latter event, for example size, shape, density and/or other in nature can be identical or different at it each other for described carrier element.
In the exemplary cases of Fig. 1, with a plurality of independently carrier elements 3 container is loaded into and is almost 100% compactedness, circle or plurality of stepped serrations by means of described container parts, described particle can be rotated as incorporate substantially carrier bed with the rotation mode of determining around the longitudinal cenlerline of described container.The internal surface of described container portions 2 is essentially smooth so that described carrier carries out accessible rotation, and described air supply device is configured on the outside surface of described container parts 2.In described embodiment, described air supply device 4 is configured in service duct 8, and this air supply device 4 is arranged in to small part and surrounds in the protective sleeve 7 of described container, and each by valve element (not shown) with import air source and link to each other.Each bar passage 8 preferably includes several air supply device or nozzles 4 along the vertical arranged in succession of described container, but the single integrated spray nozzle parts of the described container total length of basic covering also can be set.Each jet element 4 can be provided with ventilation component (for example film), and it allows the supply airflow to enter described container stop the water admission passage 8 to be clean that exists simultaneously in described container in the regular supply airflow.Described film can be used for obtaining the air filled cavity of smaller szie, and the size of air filled cavity is more little, and its buoyancy is more little, and therefore littler air filled cavity is easier in bio-reactor to be rotated in the same way with carrier.Described ventilation component also can for example be made of the pore on tool hole pipe or the biological respinse wall.Before air nozzle, can place safety net, prevent that described air filled cavity from hitting described solid support material in the mode of disrupting biofilm.Preferably link to each other configuration ventpipe (not shown) from described container, to get rid of excessive air with described outlet pipe 6.The top side of described container portions 2 can be provided with the minute ventilation (not shown), and its function is to avoid the air bag that may form on the top of described container, and this will slow down the rotation of water in the described container, thereby increases energy expenditure.These ventages preferably are connected in the ventpipe (not shown) that links to each other and dispose with outlet pipe 6.Described container 2 is preferably mounted at level attitude, and passage 8 is positioned at the interior or vertical midplane of vertical midplane of described container 2 below.In the cross section for example is under the situation of circular container substantially, and described jet element 4 for example can be configured on the one or more positions corresponding to 3,4,5,6,7,8 and 9 o ' clock positions on the common dial plate.Further be provided with the logic control that links to each other with described reactor, the supply valve of each passage can cut out alternatively, therefore and, cause described solid support material in the described container around the longitudinal cenlerline rotation of described container by the jet element progressive airflow that is present in 3～5 o ' clock positions by closing the passage 8 that for example has the jet element that is positioned at 6～9 o ' clock positions.This discontinuous rotation of solid support material drives can be for example for to carry out about 1 minute every one hour.Certainly, described cycle is aspect rotation time length and repetition rate even can be different fully therewith.In addition, the described cycle can be irregular.The another kind of mode of implementing bio-reactor of the present invention is by adjusting the air supply, in described scavenging process, drive carrier element around the longitudinal cenlerline rotation and carry out power consistence motion (dynamicconsistent motion), from described reactor, to remove mud effectively with continuous fashion.In the case, described container 2 only is provided with a ventilation component, described ventilation component preference is provided with as the position at 3 o'clock or 9 o'clock, this ventilation component for example can be to be provided with jet element and along the single air feed passage 8 of the longitudinal extension of described container 2, described jet element for example can be the ventilating pit form that forms on the wall of described container 2 corresponding to described passage.When the fluid that is adopted comprises that (wherein said reactant gases is in dissolved state to the liquid that contains reactant gases, and do not contain described reactant gases substantially and must at first therefrom be dissolved into bubble in the water), when for example containing the water of dissolved air, described fluidic supply can be carried out from the optional position (for example near position 12 o'clock) along described container periphery substantially.
The benefit that the solution of the present invention provided be the microbial process of for example avoiding turbulent flow to cause slow down (this slow down just carrier element in the process of random direction steady motion taken place).In addition, described compactedness can be higher than the compactedness of moving bed type method in fact.When comparing with the fixed-bed approach that carrier wherein is maintained fixed in described method substantially, the solution of the present invention can adopt the bigger carrier with reduced size of surface-area in the bio-reactor of every cubic units, thereby has improved cleaning capacity.In fixed-bed approach, cause the obstruction of described carrier element in order to prevent described mud, the size of described carrier element must be relatively large.Solid support material of the present invention is owing to carry out rotatablely moving of rule with intermittence or continuous fashion, and therefore than fixed-bed approach, it does not have the accumulation of mud.
The another kind of operational mode of bio-reactor of the present invention is, described air supply cycle property ground stops fully, to change described process into oxygen-free process by the aerobic process, thereby can utilize same bio-reactor space to carry out denitrification, in described denitrification, the nitrogen that exists with nitrate is reduced to nitrogen (NO
3 -→ NO
2 -→ NO → N
2O → N
2).
Bio-reactor of the present invention for example can be used as only house black liquor waste and/parts of the purification system of lixivium waste water, made before described bio-reactor it is septic tank part and anaerobic part, subsequently water to be clean is introduced described bio-reactor and handled to carry out aerobic.Preferably can carry out the second aerobic bioreactor reactor (NH of nitrification after the described bio-reactor
3→ NO
2 -→ NO
3 -), thereafter water is delivered to denitrification process.At last, the water that has purified is delivered in the phosphorus precipitation part and second settling bath.Certainly, in fact bio-reactor of the present invention has purposes widely, clean, laundry, support fishing ground and for example swimming pool cleaning water, rubbish water seepage, pit water, industrial foam water and rinse water and as sewage work, automobile, and can have in succession and/or a plurality of bio-reactors placed side by side from the purification of the waste water of flue gas scrubber etc.
Bio-reactor of the present invention also can be implemented in following embodiment, promptly, described container portions is divided into plural part, therefore some parts can be worked under aerobic conditions, promptly can be supplied with air, being suitable for making carrier, bubble and water be rotated motion in the continuous action mode in scavenging process, and other parts can be worked under oxygen free condition.In oxygen-free process, the fluid supply that causes rotating can be step, perhaps optionally, the water that described solid support material is undertaken by the opening on the wall that is positioned at described reactor or other fluidic recirculation and continuously or circulation rotatablely move, described water or other fluids do not contain the dissolved oxygen and/or the oxygenous bubble of aerobic process aequum.
Described rotatablely move also can by the fluid outside the deacration for example water cause, described water was inflated through pre-before being input to the container portions that water to be clean is housed, and described water is carried in the air that wherein contains produces bubble in the container portions of water to be clean is housed mode.It is the water of the air of dissolved state substantially that the water of described pre-inflation also can contain it, in the case, describedly contains the water that is rich in oxygen of dissolved air even can play a role in the aerobic process under the situation that does not form bubble substantially.Described scavenging process also can be the process that needs oxygen gas in addition, and in the case, fluid to be supplied can be gas or the gaseous mixture outside the deacration, perhaps also can be water or other liquid that contains described reactant gases.
The solution of the present invention not only can be implemented by the mode of tubular elongated container portions, also can adopt substantially and implement for the mode of spheric container portions, wherein said solid support material rotates with a direction symmetrically around the rotation centerline by described ball centre.As mentioned above, described solid support material can for example be made of single carrier element, perhaps carrier element or a plurality of independently carrier element by a plurality of mortise constitutes, thus, when adopting a plurality of carrier element, a plurality of carrier elements in the latter event each other can be identical or different in for example size, shape, density and/or its other properties.Therefore, on the meaning of vertical cross-section, described air supply device is between 3 o'clock～9 o ' clock positions, thereby the feasible preferred rotation centerline around basic horizontal that rotatablely moves that causes thus carries out.Described container portions also may be thought of as has the spheroid form or by the structure of the spheroid form that forms of rotation, perhaps is for example to have the sub-circular cross section and be in the ice hockey shape or the plate-like short tube of same scope or shorter length with the diameter in described cross section.
The solid support material that can be used for bio-reactor of the present invention can be made of ion-exchanger, perhaps contains ion-exchanger (for example stupalith).The use of ion-exchanger can improve denitrification, and nitrogen wherein can be caught by ion-exchanger and is edible by bacterium.Preferably, described solid support material contains polymer-ceramic mixture, for example polymkeric substance-zeolite composition.
For example make the water surface be positioned on the container by disposing described water inlet pipe and water outlet pipe, thereby making the water yield in the described container is about 100%, the described carrier element that overweights water need not other measures just can prevent to leave water body, even described carrier element has very little size.
Described carrier element is preferably sphere, so that described solid support material is realized best rotation in container portions, and obtains best compactedness.Described ball type carrier element can for example be the carrier element described in English Patent 2197308, wherein, the described water to be clean carrier element of can flowing through, or can for example be the solid sphere element, the surface of this solid sphere element has hemispherical depression, and microbial film can form safely in depression and can not contact with adjacent carrier element.
A kind of alternative shapes of carrier element is the disc-shaped element shown in Fig. 3 and 4; this element comprises middle body 32; this middle body 32 has the thickness less with respect to edge section 31; and be formed with pyramid projection 33; compare with smooth particle; described pyramid projection can realize doubling of biofilm development area, simultaneously, can also protect described microbial film when taking place to bump against with the adjacent carrier element.Described middle body can also be provided with through hole.Described dish 30 can have the diameter of for example about 5mm magnitude, and the thickness at its 31 places in the edge section can be for example be about 1mm, and its density is about 1.1kg/m
3Certainly, these values provide as just suggestive non-limiting example, and the shape of carrier element, size and density can obviously be different from afore-mentioned.The carrier element of the type it is also conceivable that and is used for for example bio-reactor of moving-bed type.
