Description
Technical field
The utility model is related to sewage disposal and reusing sewage field, more particularly to a kind of MBR equipment.
Background technology
Membrane bioreactor（Membrane Bio-Reactor, MBR）It is a kind of by membrane separation technique and biological treatment skill
The sewage disposal system that art is combined.With membrane module substitution traditional biological treatment technology end second pond, engineering is not only reduced
High activity sludge concentration is kept in floor space, and bioreactor, the ability that system handles organic loading is improved.Simultaneously
Due to the retention of seperation film, generation cycle longer microorganism, such as nitrifier can fully breed in system, therefore MBR system
Nitrification effect it is notable.
MBR system is widely used in the daily of the dispersion users such as residence district, hotel, holiday resort, school, office building
Sanitary sewage disposal, and the industry such as beer, process hides, food, chemical industry high concentration organic sewage processing.The production water of MBR system
Available for irrigating, wash, environmental sanitation, make that scape etc. is non-to drink function.If adding the technique such as counter-infiltration and sterilization, production water can be used for
Industry and the purposes such as drink.
In traditional MBR system, often aerator and film device are installed together.Purpose is reduced by being aerated
Fouling membrane.This configuration mode has two：One is that aeration quantity is big, operation energy consumption is high；Two be front and rear entrance sewage mix
It is combined, is unfavorable for the operation of system continous way.The two problems seriously constrain the application of MBR technology.
The content of the invention
The utility model is separated aerator and membrane module, and connected with transition pond by the improvement to traditional MBR system
Connect, aeration quantity, increase sewage effective processing time, the biochemical reaction environment of neatly control system can be substantially reduced, so as to solve
The certainly low shortcoming of system operation high energy consumption, continuous operation water yield.
A kind of improved MBR equipment disclosed in the utility model, including aeration tank, transition pond, UF membrane pond and equipment fortune
The required other assemblies of row and facility.Aeration tank, transition pond and UF membrane pond are both designed as narrow vertical space, wherein transition
Pond cut-off, which forms long and narrow passage, makes sewage advance in plug-flow mode.
One of improvement is, aeration tank, transition pond and UF membrane pond is both designed as into narrow vertical space, it is therefore an objective to allow
Sewage is advanced without mixing along a direction in plug-flow mode as far as possible so that sewage stream formation pollutant concentration by
High to Low gradient.The improved MBR equipment, which is tried one's best, avoids the mixed flow state of traditional MBR equipment, therefore is remarkably improved
Effluent quality, and can improve seperation film go out water speed.
The two of improvement are that transition pond cut-off, which forms long and narrow passage, makes the sewage of different biochemical stages not mix
Close, so that the gradient of sewage stream formation dissolved oxygen concentration from high to low, makes to be formed in transition pond by the aerobic biochemistry to anoxic
Reaction environment.And by adjusting the quantity of cut-off, can adjust the anaerobic condition of transition pond end.
The operation method and functions of MBR equipment described in the utility model are described in detail below：
Sewage is introduced into aeration tank, enters back into transition pond, subsequently into UF membrane pond, the row up to standard after separation membrane filtration
Put；Aeration tank provides aerobic biochemical reaction environment for sewage, and transition pond provides the aerobic biochemical reaction environment under anaerobic condition,
UF membrane pond provides aerobic biochemical reaction environment and microfiltration process.
, can be with or without pre- including clarification, anaerobism, anoxic, super oxidation etc. into the sewage of aeration tank
Processing.
In the aeration tank, bottom is provided with sewage inlet and aerator.Sewage inlet may be disposed at aeration
Above or below pipe.Sewage inlet can use distributed antipriming pipe.Aerator can use distributed antipriming pipe or porous
Plate.Because aeration tank is narrow vertical space, therefore aeration bubbles have long period and sewage during the water surface is risen to
Contact, so as to improve concentration of ordinary dissolution of the oxygen in sewage.Preferably, aerator can using aperture is tiny, hole density is big
Porous material is manufactured, and is made aeration bubbles fine and smooth, had both been reduced the rate of climb of bubble, the contact surface of bubble and sewage is added again
Product, so as to improve the dissolved efficiency of oxygen, it is possible to decrease aeration intensity, reduces operation energy consumption.
The aeration tank is adjacent with the transition pond, the sewage in aeration tank can overflow into transition pond.Transition pond along its
Length and width direction is separated, and sewage is passed through from the top or bottom of cut-off, so as to form one group of folding vertically
Passage.When sewage flows through transition pond, dissolved oxygen is gradually by microbial consumption, thus its concentration is gradually reduced.If increase cut-off
Quantity, then the passage length in transition pond and the flow time of sewage accordingly increase, now, can form scarce in the end in transition pond
Oxygen animalcule environment.Therefore, in transition pond, can occur a series of aerobic biochemical reactions to anoxic, make hardly degraded organic substance
Degraded is fully stopped, nitrification and denitrification reaction is strengthened, and ensure that phosphor-removing effect.
The final overflow of sewage in the transition pond is into adjacent UF membrane pond.The bottom in the UF membrane pond is provided with
Separating film module.Separating film module has aeration and filtering function concurrently.Aeration makes UF membrane pond form aerobe environment, reinforcing drop
COD and phosphor-removing effect.Filtering then retains the molecule in pond, including microorganism, parasite（Ovum）Deng making delivery turbidity and thin
Bacterium number amount reaches water outlet requirement.
In the UF membrane pond, several groups of separating film modules can replace water outlet and air recoil.During water outlet, discharge pressure can
Come from the liquid level static pressure in UF membrane pond, also may be from the vacuum of self priming pump.During air recoil, seperation film can both be carried out clear
It is clean, aeration can be played a part of again.Similar to the aeration tank, UF membrane pond is also narrow vertical space, therefore liquid level is quiet
Pressure ratio is larger, aeration efficiency comparison is high, so as to greatly reduce the operation energy consumption in UF membrane pond.
Sewage in the UF membrane pond can be discharged wholly or largely through seperation film.Fraction sewage is reflowable to described
In the anoxic pond of MBR front equipment ends or in the aeration tank of the MBR equipment.
Improved MBR equipment described in the utility model, similar to oxidation ditch process facility.In oxidation ditch process, pass through
Roundabout Bilge formation anaerobism, anoxic and the region such as aerobic.Then reached together by narrow vertical space in the utility model
The effect of sample.Unlike, oxidation ditch process needs the engineering land used of large area, and the utility model makes full use of vertical space
Substantially reduce occupation area of equipment.
The beneficial effects of the utility model are：Improved MBR equipment have compact conformation, technique flexibly, biochemical reaction effect
Rate is high, the low feature of operation energy consumption；Both the small-sized integrated sewage disposal device of manufacture it had been adapted to, also being adapted for extensive sewage disposal should
With；Both the place of the high-concentration sewages such as percolate, industrial wastewater can be can also be applied to using the processing with common sanitary sewage
Reason, and more significant treatment effect can be obtained.
