Description
Technical field
The present invention relates 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 processes organic loading is improve.Simultaneously
Due to the retention of seperation film, generation cycle microorganism more long, 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 treatment.The product water of MBR system
Can be used to irrigating, wash, environmental sanitation, making that scape etc. is non-to drink function.If adding the technique such as counter-infiltration and sterilization, produce water and 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 by being aerated reduction
Fouling membrane.This configuration mode has two:One is that aeration rate is big, operation energy consumption is high;Two be front and rear entrance sewage mix
It is combined, is unfavorable for that system continous way is run.The two problems seriously constrain the application of MBR technology.
The content of the invention
The present invention is separated aerator and membrane module by the improvement to traditional MBR system, and is connected with transition pond,
Aeration rate can be substantially reduced, increase the biochemical reaction environment of sewage effective process time, neatly control system, thus solve be
The shortcoming that system operation energy consumption is high, continuous operation water yield is low.
A kind of improved MBR equipment disclosed by the invention, including aeration tank, transition pond, UF membrane pond and equipment operation institute
The other assemblies and facility for needing.Aeration tank, transition pond and UF membrane pond are both designed as narrow vertical space, and wherein transition pond is used
Cut-off forms long and narrow passage makes sewage advance in plug-flow mode.
One of improvement is aeration tank, transition pond and UF membrane pond to be 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 formed pollutant concentration by
High to Low gradient.The improved MBR equipment is tried one's best and 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 forms long and narrow passage makes the sewage of different biochemical stages not mix
Close, so that sewage stream forms dissolved oxygen concentration gradient from high to low, make to be formed by the aerobic biochemistry to anoxic in transition pond
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 of the present invention are described in detail below:
Sewage is introduced into aeration tank, enters back into transition pond, subsequently into UF membrane pond, the qualified discharge after separating membrane filtration;
Aeration tank provides aerobic biochemical reaction environment for sewage, and transition pond provides the aerobic biochemical reaction environment under anaerobic condition, film
Separate tank provides aerobic biochemical reaction environment and microfiltration process.
Into the sewage of aeration tank, can be with or without including pre- including clarification, anaerobism, anoxic, super oxidation etc.
Treatment.
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 be using aperture is tiny, hole density is big
Porous material is manufactured, and makes aeration bubbles fine and smooth, has both reduced the rate of climb of bubble, and the contact surface of bubble and sewage is increased 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, and the sewage in aeration tank can be in overflow to transition pond.Transition pond is along it
Length and width direction is separated, and sewage is passed through from the top of cut-off or bottom, so as to form one group of vertical folding
Passage.When sewage flows through transition pond, dissolved oxygen is gradually by microbial consumption, thus its concentration is gradually reduced.If increasing 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, a series of aerobic biochemical reactions to anoxic can occur, makes hardly degraded organic substance
Degraded is fully stopped, nitrification and denitrification is reacted and is strengthened, and ensure that phosphor-removing effect.
In the final overflow of sewage to adjacent UF membrane pond in the transition 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 clearly
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 wholly or largely separated film discharge.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 of the present invention, similar to oxidation ditch process facility.In oxidation ditch process, by roundabout
Bilge form anaerobism, anoxic and the region such as aerobic.Same effect is then reached by narrow vertical space in the present invention.
Unlike, oxidation ditch process needs the engineering land used of large area, and the present invention makes full use of vertical space to substantially reduce equipment
Floor space.
The beneficial effects of the invention are as follows:Improved MBR equipment have compact conformation, technique flexibly, biochemical reaction efficiency high,
The low feature of operation energy consumption;Both it had been adapted to the small-sized integrated sewage disposal device of manufacture, also had been adapted for extensive sewage disposal application;Both
The treatment with common sanitary sewage can be applied, the treatment of the high-concentration sewages such as percolate, industrial wastewater is can also be applied to, and
More significant treatment effect can be obtained.
