The present invention will be described in detail below with reference to the accompanying drawings: shown in Fig. 1, a kind for the treatment of of Organic Wastewater of the present invention
Device, it includes waste water lifting pump 1, MBR reactor 15 and UASB reactor 3, and 31 end of water outlet of the UASB reactor 3 is set
There is a pulser 2, the pulser 2 water pipe 16 connects waste water lifting pump 1, and the outside of the UASB reactor 3 is equipped with a water
Sealed cans 5, described 3 one end of UASB reactor are connect with one end water pipe 17 of MBR reactor 15, the MBR reactor 15 it is another
One end connects pulsating pump 12, and water is sucked clear water reserviors 13 by the pulsating pump 12, and the inside of the UASB reactor 3 is equipped with three-phase separate
From device 4, one section of connection water sealed tank 5 of the three phase separator 4, the device of a lateral edge UASB reactor of the three phase separator 4
Wall is equipped with the apopore 18 being connected with MBR reactor, and the apopore 18 designs for mill weir, the bottom of the UASB reactor 3
Portion is additionally provided with the collection chamber 19 for collecting gas.
It is as shown in the figure: to be equipped with aerobic tank 8 and membrane cisterna 9 in the MBR reactor 15, used between the aerobic tank 8 and membrane cisterna 9
Baffle separates 20, and the bottom of the baffle 20. is equipped with notch, and interior be equipped with of the aerobic tank 8 is used for floating stuffing 7, described outstanding
Floating 7 height of filler is flushed lower than baffle top with bottom notch, and membrane module purging device 10 is equipped in the membrane cisterna 9, described to blow
The top for sweeping device 10 is equipped with membrane module 11, and the top of the membrane module 11 is equipped with a pulsating pump 12, the bottom of the MBR reactor 15
Portion is additionally provided with air blower 14, and wind is passed through in aerobic tank 8 and membrane cisterna 9 by the air blower 14.
Column are preferably implemented: as shown in Figure 2: high-concentration waste water is delivered to UASB reactor pulser, waste water warp by elevator pump
After pulse amplifying, even into reactor bottom, upwardly through the Sludge Bed comprising granule sludge or floc sludge.Anaerobic reaction
The process contacted in waste water and mud granule occurs.The biogas (mainly methane and carbon dioxide) generated under anaerobic state draws
Internal circulation is played, this is advantageous for the formation and maintenance of granule sludge.Dirt is attached in some gases that sludge blanket is formed
On mud particle, attachment and the gas not adhered to rise to reactor head.The sludge for rising to surface hits phase reactor
The bottom of gas launcher causes the sludge wadding body of bubbles attached to deaerate.Mud granule will be deposited to Sludge Bed after bubble release
Surface, attachment and the gas that does not adhere to are collected into the collection chamber of the three phase separator of reactor head.It is placed in collection chamber
The effect of baffle under unit interstices is gas launcher and prevents biogas bubble from entering settling zone, otherwise will cause settling zone
Wadding it is dynamic, particle can be hindered to precipitate.Liquid comprising some remaining solids and mud granule enters precipitating by separator gap
Area.
Since the area of passage of the skew wall settling zone of separator increases when close to the water surface, upflow velocity is in close row
Put a reduction.It can flocculate and precipitate in settling zone since flow velocity reduces sludge wadding body.Accumulate the sludge on three phase separator
Wadding body will be more than that it be maintained at the frictional force on skew wall to a certain extent, will slide back to reaction zone, this partial sludge again will be with
Entering organic matter of water reacts.
Clear water flows into MBR reactor by effluent weir, and floating stuffing is installed in reactor, under conditions of aeration, using outstanding
The aerobic microbiological on filler is floated, organic matter in degrading waste water purifies water, and water outlet enters membrane cisterna, then saturating by suction pump
Cross MBR membrane module extraction device, qualified discharge.
Feature of the present invention are as follows: 1) anaerobic reactor organic loading is high, and hydraulic detention time is short, and no returned sludge equipment is leaned on
The ascending motion of the biogas generated in reaction process makes the sludge on Sludge Bed top be in suspended state, to lower part sludge blanket
There is a degree of agitation, system without mixing saves the energy.
2) high to the removal rate of pollutant, anti-pollution mud swelliong power is strong, and stable effluent quality is reliable, does not suspend in water outlet
Object；
3) membrane bioreactor realizes the control respectively of reactor sludge age (STR) and hydraulic detention time (HRT), because
And its design and operation greatly simplify；
4) the mechanical retention effect of membrane module avoids the loss of microorganism, can keep high sludge in membrane bioreactor
Concentration reduces sludge loading so as to improve volume load, has extremely strong impact resistance；
5) since SRT is very long, membrane bioreactor plays the role of " sludge nitrification tank " again, to substantially reduce sludge
Yield, excess sludge production is low, and Treatment of Sludge expense is low；
6) it since the effect of shutting off of membrane module extends SRT, has built and has been conducive to be proliferated slow microorganism, such as nitrified thin
The environment of bacterium growth, can be improved the nitrification ability of system, while be conducive to improve the processing effect of larger molecular organics difficult to degrade
Rate and it is promoted thoroughly to decompose；
7) activated sludge of membrane bioreactor will not be lost with water outlet, and in the process of running, activated sludge can be because entering
The variation of organic concentration and change, and reach a kind of dynamic equilibrium, this makes system stable water outlet and has the spy of anti impulsion load
Point；
8) membrane bioreactor is easy to integration, it is easy to accomplish automatically controls, convenient operation and management；
9) technique omits existing secondary settling tank, reduces occupied area.
10) floating stuffing is added in membrane bioreactor, species are complete, and quantity is sufficient, can form complete micro- life
Object decomposes chain, complete decomposition.Under identical biomass, the suspension microorganism into membrane cisterna is small, reduces fouling membrane.
