Description
Technical field
The utility model relates to sewage treatment area, and specifically, the utility model relates to a kind of MBR film group device refining plant.
Background technology
MBR membrane bioreactor (Membrane Bioreactor is called for short MBR) is one of novel waste water technology of membrane separation technique and biotechnology combination, also claims the film separated activated sludge method.The efficient cutoff performance that it utilizes membrane separation assemblies carries out solid-liquid separation, has effectively reached the purpose of mud-water separation.
The MBR membrane bioreactor is played the part of more and more important effect in WWT, European Union requires in its member states, to widely popularize the MBR technology.The giant in the world such as the GE of General Electric (U.S.A.), the siemens of Germany, the Mitsubishi of Japan, this piece cake is all being fought for by numerous companies such as the LG of Korea S.The MBR membrane bioreactor is except making high performance hollow fiber ultrafiltration membrane silk, and the technology of controlling diaphragm silk pollution in use is also very important.
The method that existing controlling diaphragm silk pollutes mainly is to film group device aeration, matting and uses the clear water back flushing.Aeration is that the film group device controlling diaphragm pollutes main method, and it is when utilizing bubble in film group device, to rise, and forms unsettled air water blended two-phase flow, impels the shake of film silk, and the mud that the film surface attaches is shaked off.The main drawback of aeration is that energy consumption is high, and this also becomes the development bottleneck of MBR technology.Matting needs a large amount of medicaments, and promptly troublesome poeration has secondary pollution again, and expense is high.Back flushing is with the water pump of using after handling through the film silk, oppositely injects in the film group device, promptly is injected into the inside of film silk, lets clear water from inside to outside flow out, and the mud that gets lodged in membrane micropore is rushed out.The shortcoming one of back flushing is to consume clear water, the 2nd, troublesome poeration.Seldom use in the production.
The utility model mainly is the improvement of carrying out to backwashing technology of the prior art.
To the deficiency of above method, the utility model exploitation is a kind of promptly simple, energy-conservation again MBR film group device refining plant.
The utility model content
In view of the problem that exists in the prior art, the purpose of the utility model is to provide a kind of MBR film group device refining plant.
For realizing above-mentioned utility model purpose; The technical scheme that the utility model provides is: a kind of MBR film group device refining plant, comprise the film group device that is placed in the sewage biochemistry pool, and the bellows water outlet of film group device connects suction pump through suction tube; Suction pump connects clean water basin through rising pipe; Suction tube is provided with a pneumatic quick closing valve butterfly valve, and pneumatic quick closing valve butterfly valve connects cylinder and air compressor machine through tracheae, is provided with the SV that is connected with the PLC unit between cylinder and the air compressor machine.
Also be provided with a current limliting SV between described cylinder and the air compressor machine.
Also be provided with a SV on the described suction tube.
The described rising pipe that is connected with clean water basin is provided with flowing water Valve.
The beneficial effect of the utility model is: the utility model utilizes the valve quick closing valve to produce water hammer film group device is purified, simplicity of design, and the energy-saving and water-saving effect is obvious, will play an important role to applying of MBR membrane Bio-reactor Technology.
Description of drawings
When combining accompanying drawing to consider; Through with reference to following detailed, can more completely understand the utility model better and learn wherein many attendant advantages easily, but accompanying drawing described herein is used to provide the further understanding to the utility model; Constitute the part of the utility model; Illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model, wherein:
Fig. 1 is the structural representation of the utility model.
Embodiment
Embodiment to the utility model describes below in conjunction with accompanying drawing.
With reference to Fig. 1; When prior art is normally moved; The micropore on hollow-fibre membrane 3 surfaces infiltrates through in the hollow-fibre membrane centre hole in the film group device 2 that water is installed from sewage biochemical reaction pond 1, gets into clean water basin 9 through bellows 4, suction tube 5, suction pump 7, water pump water outlet valve 8 again; The utility model on this basis; With the suction tube 5 that is connected of suction water pump 7 on pneumatic quick closing valve butterfly valve 6 is set, pneumatic quick closing valve butterfly valve 6 connects cylinder 10 and air compressor machine 11 through tracheae, is provided with the SV 12 and the current limliting SV 13 that are connected with PLC unit 15 between cylinder and the air compressor machine.
The speed of current about with 1m/s flows forward in the general pump water inlet, and when PLC unit 15 provides signal, SV 12 is opened fast; To cylinder 10 inflations, because of large-minded, pressure is high by air compressor machine 11 for pressurized air; 6 moments of pneumatic quick closing valve butterfly valve close, and cut off current.Because the inertia effect of current before butterfly valve, forms a pressure pulse, promptly surge is commonly called as water hammer.Water hammer is propagated along suction tube with the form of ripple backward, and (direction is seen dotted arrow) through bellows, it is inner to arrive the film silk again.This pressure wave impels instant water to flow backwards, and the utility model is exactly a phenomenon of utilizing instant water outwards to flow backwards in the film silk, goes out externally with getting lodged in pollution substance in the membrane micropore, reaches the purpose that controlling diaphragm pollutes.
The operation scheme that pneumatic quick closing valve butterfly valve 6 adopts quick closing valves, opens slowly, the time of pass was 1 second, that opens was lasted for for 5 seconds.Slowly opening is to adopt current limliting SV 13 to carry out current limliting, and opening slowly also is for avoiding producing water hammer.
At pump works, water hammer is a kind of destructive disaster, and the high pressure of water hammer can be with valve; Pipeline breaks, so develop the equipment of various prevention water hammers.Too high for preventing water hammer pressure, the utility model is provided with a SV 14 on suction tube.When hypertonia, SV 14 is opened, and carries out pressure release.
Pneumatic quick closing valve butterfly valve 6 close frequency, generally decide according to water quality, adopt and closed once by 8 minutes in 3 minutes.Because it is very short that operation lasts, when pneumatic quick closing valve butterfly valve cut out, suction pump 7 was not shut down.Equally, aeration tube does not stop aeration yet, still, and the comparable original reduction of aeration intensity.The turbulent flow that aeration produces in film group device mainly is a dirt of removing film silk outside surface, and the refluence that water hammer produces mainly is the pollution substance of removing in the membrane micropore.The two is collaborative, and the combination of inner and outside can be polluted by more effective controlling diaphragm
