Multiple preferred embodiments that the present invention is introduced below with reference to Figure of description, keep its technology contents more clear and just
In understanding.The present invention can be emerged from by many various forms of embodiments, and protection scope of the present invention not only limits
The embodiment that Yu Wenzhong is mentioned.
A kind of technology of low-consumption high-efficiency aerobic particle mud method processing brewery industry waste water, it is anti-in aerobic particle mud
Answer device interior design that two pieces of rigid water conservancy diversion sieve plates and three phase separator are installed.Interior cycle up-flow is settled by three reaction zones and one
Area, four parts composition；Granule sludge, which changes to be formed, to be divided into as five stages：Startup stage, forms little particle rank at the flco stage
Section, Granular sludge formation stage and the granule sludge stage of ripeness, i.e., four five stages of composition.Adjust organic loading, hydraulic shear, molten
Oxygen is solved, oxygen, organic matter, microorganism is made to be thoroughly mixed to form particle.Using the small rill diffused aeration dish of diamond dust, make in reactor
It is more uniform that aeration homogeneous mixture liquid consolidates three phase separation.A kind of biology mainly formed by bacterial digestion is formd in reactor
The Tiny ecosystem particle that dimeric structure and Extracellular polymers are constituted, growth form the research of granule sludge process, explore and solve Gao Pin
The rapid culture technique problem of matter aerobic particle mud.
Aerobic granular sludge reactor, organic wastewater enter reactor, are needed inside granule sludge through dissolved oxygen, microorganism absorbs
Digestion, under the conditions of resistant, dissolved oxygen slowly enters inside from granule sludge surface, and multiple-microorganism is total in granule sludge
Life coexists.Cell aggregation object is the key factor for maintaining aerobic particle mud to stablize.Hydraulic shear can stimulate granule sludge
Metabolism ensures the balance of aerobic particle mud biological structure under existing hydraulics.The metabolism of granule sludge and hydraulic shear
Power is closely related.Polymer plays an important role for the accumulation of apposition growth flocculation bacterium.Hydraulic shear high energy promotes aerobic
Granule sludge and biomembrane secrete more cell aggregation objects, and the variation of microbial metabolism is also shown to be had in the case where there is pressure condition
Help to be formed closely stable biocenose and particle, grain size 1.0-3.5mm.But also have compared with small particle 0.5mm and greater particle size
The particle of 4.0mm coexists in reactor, and the color of granule sludge is brown, and average grain sludge age is 3-5 days, and particle is dirty
Mud diameter increases, and sinking speed also increases, and settling property is much better than traditional activated Sludge System.It ensures in high-load condition
The quick removal of lower organic matter has in reactor higher microbial biomass to stop.Biomass concentration is higher than traditional activated sludge
Microbial biomass concentration in system, operating system reach gas-liquid-solid three-phase separating effect well.
Shorter hydraulic detention time and larger flow shear action contribute to form in aerobic granular sludge reactor
Granule sludge.The selection of sedimentation time is to influence the principal element of granule sludge flora.It has now been found that aerobic particle mud
It can be used for synchronous nitration and denitrification biological phosphate-eliminating and toxic heavy metal and bio-refractory organic wastewater.Therefore granule sludge is living
Property sludge microbe self-retaining process under aerobic environment.Ultimately form biopolymer, shape regular texture is compact, it is intensive,
Growth is rapid.It can also survive when organic concentration is relatively low, living environment temperature requirement relative loose, granule sludge has opposite
Closely knit delicate structure, the sludge retention of higher concentration and the close symbiosis of various microbial population, excellent precipitation
Performance, granule sludge is brown, and surface is smooth, most rounded or oval, close structure.Since condition of culture is different,
Grain particle size range is wider, and from a few tenths of a mm to several millimeters, little particle has more closely knit structure, and bulky grain structure is then
It is relatively soft.Granule sludge is had extremely excellent by biomass, Extracellular polymers, inorganic constituents and gap and package water composition
Settling property.Aerobic granular sludge reactor processing waste water has higher reaction rate, high by two than conventional activated sludge method
To four times, the treatment effeciency of unit volume reactor is greatly improved.
The characteristic of aerobic granular sludge reactor organics removal
1, entering organic matter of water
The coordination ratio of C.N.P contributes to form aerobic particle mud in organic wastewater, and different organic wastewater is in difference
Carbon source culture under aerobic particle mud microbiologic population and structure also there is apparent difference, activated sludge to contribute to bacterium
Between the perfect intimate symbiosis of mutual polymerization.Technique difference has great influence to the formation of aerobic particle mud.
2, COD loads BOD is removed
Aerobic granular sludge reactor, COD rate of load condensates are up to 1.0 --- 2.0kgCOD/ (m3.d), when COD loads are higher
When can cause filamentary discharges, be the physical arrangement and shape that unfavorable meeting influences granule sludge on culture granule sludge.
Biological oxidation removes BOD in aerobic particle mud complete, and waste water matrix species are more, removal rate
Different, when BOD is more than certain numerical value, the BOD removal rates of unit microbial cell amount are kept constant, when remaining in solution
In organic matter concentration decline when, total removal rate will reduce because more degradable organic matter will be removed first.BOD
Removal rate is also up to 0.5-1.5kg/ (m3.d)。
3, hydraulic shear
The size of aeration quantity not only influences the oxygen-supplying amount of reactor to pelletising process in aerobic granular sludge reactor
Important function is played, keeps higher hydrodynamic shear to be conducive to the formation of aerobic particle mud in reactor and stablizes fortune
Row.To play an important role to pelletising process, the size of hydrodynamic shear is one that influences activated sludge particles
Key factor, only when hydrodynamic shear is higher than a certain value in reactor, aerobic particle mud can be formed, and reactor is worked as
In shearing force it is excessively high when particle between abrasion reinforce, cause the fragmented of particle to be cracked.
4, hold oxygen and granule sludge generates
In aeration, biological degradable part is aoxidized, and degradable moiety content is made to decline, the amount of degradable part with
Endogenous oxidized rate and granule sludge are related.The amount of degradable part regards microorganism as with the amount of speed of oxygen intake suspended solid
Amount, biological oxidation process is related with the organic matter of process is entered, in logarithm growth stage, speed of oxygen intake, with neoblast synthetic quantity
Increase and rise.
5, hydraulic detention time
Active particle culturing sludge cycle time generates a growing environment and surrounding to microbiologic population in system
The difference to absorb nourishment, cycle time length determine frequency of the floc sludge with granule sludge with water outlet discharge in reactor.
Also hydraulic detention time is determined.During active particle sludge grown cultures, smaller relatively light and dispersion floc sludge quilt
Flush out system.Larger and heavier granule sludge is then trapped in the reactor, during aerobic particle mud grown cultures
Hydraulic retention will have time enough to inhibit suspended sludge growth, also have the sufficiently long time to keep microorganism numerous in the reactor
It grows and accumulates, keep balance commensalism symbiosis.
6, dissolved oxygen content, temperature and PH effects
Dissolved oxygen concentration is an important parameter for influencing aerobic sewage disposal system operation, in activated sludge, dissolving
Aerobic particle mud, which can generate oxygen, when oxygen concentration is down to when 0.7mg/L or higher than 3mg/L must diffuse into granule sludge flco,
It is needed with the oxygen of the internal microbial bacterial of supply.Oxygen depends on granule sludge oxygen consumption rate to the penetration depth of granule sludge.Particle
Sludge oxygen consumption rate is directly proportional to organic loading.Therefore when organic loading increases, the requirement of dissolved oxygen is consequently increased.
Influence of the temperature to Granular sludge formation, mainly at low temperatures and high temperatures, the activity of microorganism is suppressed, and is made
Granulation progress is affected, since the growth and breeding of each microbial bacterial is all there are one suitable temperature range (20-34
DEG C), desirable strain mass propagation can be made by the temperature for controlling certain, inhibit the activity of other strains.All lifes
Object process is related with temperature, and the rate of biological respinse increases with temperature rise, biologic grain sludge flco at 36 DEG C or more
Rupture is decomposed, and protozoan and metazoa disappear at 38 DEG C, and Filamentous flco is main flco, and granule sludge culture growth is lost
Control.Temperature in reactor declines the rising that can cause suspended solids content in water outlet, and partial particulate sludge decomposition disperses, these
Solid will not automatic sedimentation in dispersed.
Influences of the PH to aerobic particle mud culture growth course.Not to the shadow of anaerobic grain sludge culture growth course
Sound is so apparent.Effective PH ranging from 6.0--8.0 of most of biological oxidation system, waste water enter aerobic particle mud reaction
It is diluted after device, and breathes the carbon dioxide reaction released with microorganism appearance oxygen and be neutralized.PH7.5 or so can be effectively
Buffer aerating system.Alkali number in waste water is related with BOD removals because BOD removals will produce carbon dioxide, carbon dioxide can and
Alkali reaction in water, there are above-mentioned buffer systems only in processing procedure, even if the acid-base property of waste water has certain fluctuation, aeration
PH in reactor will also maintain 7.5 or so.
7, the growth of granule sludge and structure
Aerobic particle mud is that aerobic microbiological contacts with each other under certain physiological condition between microbial cell and bacterium
Assemble so formed a kind of most perfect most intimate symbiosis, leave be impossible to each other individually survive formed particle dirt
Mud, and the microbial aggregate with multilayered structure densification are uniformly distributed liter in specific hydraulics and reactor water inlet
Microbial is mutually assembled and becomes granule sludge in the case of stream mixes entirely.
8, principle of peactor
Column pot type flows up aerobic granular sludge reactor, using larger height and internal diameter ratio, is conducive to generate circulation,
There is sufficiently long hydraulic retention, keep higher fluid shearing, increase dissolved oxygen amount, makes microorganism condensate in reactor always
It is under hydraulic friction effect, there is the microbial aggregate of multilayered structure densification, gradually form the grain shape of rule, be conducive to
The formation of granule sludge.The formation of aerobic particle mud needs to meet certain biochemistry and physicochemical condition.
Using novel aerobic granular sludge reactor, culture aerobic particle mud uniformly dissipates around from bottom distributor
Cloth (as shown in Figure 2) can -- aeration -- mixing -- floc sludge -- cotton-shaped fine particle -- particle dirt of continuum micromeehanics or intermittent water inflow
The operational mode of mud -- water outlet is conducive to active sludge granulation process, promotes aerobic particle mud culture growth.
As shown in Figure 1, novel aerobic granular sludge reactor is that carbon steel body is cylindric, reactor shell is 10 meters high, diameter 5
Rice, 9.5 meters of available depth, effective volume 200m3, interior design two pieces of steel water conservancy diversion sieve plates of installation of reactor are (such as Fig. 3 institutes
Show) and three reaction zones of three phase separator point, the first reaction zone 1 is 3 meters high, and main function is to improve air in reactor
It is thoroughly mixed degradation reaction with digestive juice, and is played and is increased oxygen content amount and air bubble is smashed or micro-bubble makes the quick oxygen uptake of sewage
Haptoreaction, sludge are driven into second reaction zone 2 by air-flow and move upwards, and 2 high 4 meters of second reaction zone, main function is anti-
It answers to be formed inside device and circulate, hydraulic shear under low aeration intensity is made to enhance, oxygen need to enter micro- inside flco supply flco
Biological is aerobic.Contribute to form aerobic particle mud, oxygen to the penetration depth of particle depend on particle ambient oxygen concentration and
Particle oxygen consumption rate.Granule sludge oxygen consumption rate is directly proportional to organic loading, therefore, when organic loading increases, in order to
It is to be consequently increased (the quick shape of water conservancy diversion sieve plate superhigh speed dissolved oxygen low speed up-flow to maintain enough aerobic particle muds to hold the needs of oxygen
At the effect of granule sludge) 3 high 2.5 meters of third reaction zone, main function is that gas-liquid-solid three-phase separation is more uniform in reaction zone.
When the concentration of organic matter declines, total removal rate will be reduced, and be conducive to bioflocculation, and adsorption-decomposition function organic matter makes activity
Grain sludge is easy to settle.
Reactor uses larger ratio of height to diameter and deflector ratio, can adjust organic loading, dissolved oxygen amount on a large scale.Make oxygen, organic matter,
Microorganism is sufficiently mixed, and forms granule sludge fast degradation.Secondary settling tank, the outer row of reflux sedimentation are at the uniform velocity drained into using downflow weir
Sludge.The CODmg/L60-90.NH of water outlet+4-Nmg/L10-20。
