Background technology
At present, aerobic particle mud (Aerobic Granular Sludge, AGS) be that microorganism is under certain environmental conditions by granulated activated mud that self-cohesion action is formed, the microorganism wherein comprised is common species, and they constitute due to the physiological effect of interdepending a kind ofly stablizes closely knit structure.As everyone knows, in sewage disposal, aerobic biological treatment process is general more than Anaerobic treatment technique application, but obviously lags behind anaerobic grain sludge to the research of aerobic particle mud.The Optimality of anaerobic grain sludge has caused investigator to the interest of cultivating granule sludge under aerobic condition, the research of people to aerobic particle mud be based upon anaerobic grain sludge basis on.
At Mishima and Nakamure in 1991 at aerobic upflow sludge blanket (AUSB, AerobicUpflow Sludge Blanket) in Late Cambrian there is good sedimentation function, the particle diameter aerobic particle mud between 2 ~ 8mm, just cause global extensive concern.
Aerobic particle mud has following features compared to traditional floc sludge and anaerobic grain sludge:
(1) aerobic particle mud has good settling property, and water outlet does not need to arrange settling tank, greatly reduces construction investment and the cost for the treatment of facility.
(2) aerobic particle mud particle physical strength is high, not easily causes sludge loss because the reason such as flow shear and inner aerogenesis is broken.
(3) structure of aerobic particle mud is closely knit, biomass contained by unit volume mud is large, not only can protect the bacterium (as nitrifier) comparatively responsive to environment, it is made to be weakened by the impact of toxic substance, stronger impact load can also be tolerated, thus system processing efficiency and stability can be improved;
(4) aerobic particle mud startup period ratio anaerobic grain sludge is short, can cultivate at normal temperatures simultaneously;
(5) aerobic particle mud is compared anaerobic grain sludge have greater advantage when being processed low-concentration organic waste water (as city domestic sewage), and when processing high concentrated organic wastewater, clearance is higher does not need subsequent disposal:
(6) aerobic particle mud has stronger denitrogenation dephosphorizing ability.Because the relation of mass transfer exists multiple oxygen environment simultaneously in aerobic particle mud, for microorganism of different nature provides living environment suitable separately.Therefore denitrogenation dephosphorizing can be realized individually or simultaneously.
The Novel state Sewage treatment systems that membrane bioreactor (Membrane Bio-Reactor, MBR) organically combines for membrane separation technique and biologic treating technique.It replaces the second pond of traditional biological treatment technology end with membrane module, keeps higher sludge concentration in bio-reactor, improves the organic loading of biological treatment, thus reduces the floor space of sewage treatment facility.It mainly utilizes the membrane separation plant be immersed within aerobe pond to retain active sludge and larger molecular organics.Membrane bioreactor, because of its effective crown_interception, can retain generation cycle longer microorganism, can realize deep purification of waste water.
Membrane bioreactor is made up of membrane module and bio-reactor two portions, divides according to this two-part combination, can be divided into external placed type and the large class of immersion two.External membrane bioreactor refers to that the mixed solution of bio-reactor enters membrane module after pump supercharging, the penetration by liquid film under the effect of the pressure in mixed solution, becomes system process water; Solid and macromolecular substance etc. then tunicle retain, and are back in bio-reactor with concentrated solution.Nets impregnated refers to membrane module to be placed in reactor, by vacuum pump or the suction of other type of pump, obtains filtered liquid.
Membrane bioreactor, compared with traditional biological treatment technology, has following principal feature: processing efficiency is high, effluent quality good, little, the easy realization of facility compact, floor space controls automatically, operational management is simple.MBR is really applied, the most important thing is to overcome fouling membrane, increase membrane flux, extend membrane lifetime.
Bioreactor of dynamic membrane is the novel process that traditional MBR technology combines with membrane technique, put forward on the basis of MBR, according to the difference of the formation basic theory of Dynamic Membrane, bioreactor of dynamic membrane is divided into " self-forming dynamic membrane bioreactor " and " precoated dynamic membrane bio-reactor ".Precoated dynamic membrane first filters the solution containing filmogen with porous supporting body usually, until Dynamic Membrane after its surface is formed, then filters processed solution with it.Self-forming dynamic membrane is then formed in open support surface by the material in solution when filtering processed solution.The filmogen of self-forming dynamic membrane is active sludge, and the filmogen of precoated dynamic membrane is MnO 2, the material such as active carbon powder.The film base material of Dynamic Membrane is generally industrial filter cloth, nylon bolting silk, non-woven fabrics, Stainless Steel Cloth, pottery, sintered glass, sintering metal etc.
Bioreactor of dynamic membrane is that the microgrid material of selection cheapness carrys out alternative micro-filtration or ultra-filtration membrane mould material is processed into filter assemblies and sets up bio-reactor, compared with traditional MBR, bioreactor of dynamic membrane, except having the major advantage of traditional MBR, also has the advantage of the following aspects:
(1) capital construction and maintenance cost low: the price of microgrid material is well below the ultrafiltration of costliness, microfiltration membrane material;
(2) membrane flux is large: Dynamic Membrane adopts the microgrid material of larger aperture, and basement membrane resistance is little.
(3) working cost is low: the filtration resistance of microgrid material is little, does not need to draw water under the effect of pump, water outlet of just can flowing automatically under relying on the less waterhead of reactor, and energy consumption is low;
(4) fouling membrane is easier to remove: Dynamic Membrane is easier to be separated from mould material surface, during cleaning together with adsorbed pollution substance and microbial metabolites together by wash-out, membrane flux is effectively recovered.
However, bioreactor of dynamic membrane still exists and denounces, i.e. fouling membrane.
