Description

A kind of novel all-in-one alternative expression A-MBR bioreactors and its processing method

Technical field

Field is made the present invention relates to MBR film process reactor.

Background technology

Original MBR film process reactor runs for monofilm pond single system, and the method for operation is generally product water and pauses 2 points for 8 minutes Clock (a cycle）, and so on, and after one section of run time also need shutdown to be backwashed to be blocked to reach anti-film, extend film The purpose of service life.The system disadvantage is：1 as produce water be used for other purposes when, shut down the backwash time period water occurs Amount is not enough or anhydrous available situation；2 train backlash are washed need to design recoil service sink, and install recoil water pump, and investment is big, accounts for Ground is big；3 running efficiency of system are relatively low, there is the space of raising efficiency.

The content of the invention

The present invention is in view of the shortcomings of the prior art, there is provided one kind completes alternately backwash during being paused using equipment, Backwash is shut down without taking again, and alternately backwash realizes the continuous product water of system, improves product water efficiency；Alternately backwash is sharp Backwashed with product water pump, without setting backwashing pump again, and by the use of MBR membrane cisternas as recoil service sink, saved recoil clear Wash pool, reduces investment, reduces occupation of land, and it is biological anti-to reduce the novel all-in-one alternative expression A-MBR of the complexity of operation Answer device and its processing method.

To realize the object of the invention, there is provided following technical scheme：A kind of novel all-in-one alternative expression A-MBR biological respinses Device, including anaerobic pond, MBR membrane cisternas and equipment room, it is characterised in that the MBR membrane cisternas that MBR membrane cisternas are arranged in parallel by 1#, 2#, 1#, 1#MBR films group, 2#MBR film groups are each provided with the MBR membrane cisternas that 2# is arranged in parallel, product water backwash tube is provided with equipment room Road, 1#MBR films group sets No. 1 water producing pipe connection ultraviolet ray disinfector, and it is same ultraviolet that 2#MBR films group sets No. 2 water producing pipe connections Line sterilizer, is provided with 1# and produces water pump on No. 1 water producing pipe, 2# is provided with No. 2 water producing pipes and produces water pump, and 1# produces water pump rear side and sets A number backwash pipeline connection 2# produces water pump front side, and 2# product water pump rear sides set No. two backwash pipeline connection 1# and produce on front side of water pump, one, 1#, 2# backwash valve are provided with No. two backwash pipelines, 1# produces water pump and No. two backwash pipeline enclosures are provided with cut-off on No. 1 water producing pipe Valve, 2# produces water pump and a backwash pipeline enclosure is provided with stop valve on No. 2 water producing pipes, on No. 1 water producing pipe after a backwash pipeline Side is provided with check valve, 1# and produces water valve, and No. two backwash pipeline rear sides are provided with check valve, 2# and produce water valve on No. 2 water producing pipes.

To realize the object of the invention, there is provided a kind of novel all-in-one alternative expression A-MBR bioreactor for treatment methods, it is special Levying makes 1#, 2# product water pump often run 8min stoppings 2min as a cycle when being and running, 1# is produced water pump and 2# by reciprocal operation The rule run time section for producing water pump staggers, and any one is produced water pump within the 2min time periods paused by another product water pump pair It completes recoil, and recoil interval time can adjust according to actual conditions.

Beneficial effect of the present invention：The present invention had both extended the service life of film, it is ensured that system continuously produces water, also saves Investment, reduces occupation of land.

Specific embodiment

Embodiment 1：A kind of novel all-in-one alternative expression A-MBR bioreactors, including anaerobic pond 1, MBR membrane cisternas 2 and Equipment room 3, the MBR membrane cisternas that MBR membrane cisternas 2 are arranged in parallel by 1#, 2# are each provided with the MBR membrane cisternas that 1#, 2# are arranged in parallel Product water backwash pipeline is provided with 1#MBR films group 2.1,2#MBR films group 2.2, equipment room 3,1#MBR films group 2.1 sets No. 1 product water Pipe 4 connects ultraviolet ray disinfector 5, and 2#MBR films group 2.2 sets No. 2 water producing pipes 6 and connects 5, No. 1 product water of same ultraviolet ray disinfector It is provided with pipe 4 and 2# product water pumps 8 is provided with 1# product 7, No. 2 water producing pipes 6 of water pump, 1# produces the rear side of water pump 7 and sets a backwash tube The connection 2# of road 9 produces the front side of water pump 8, and the rear side of 2# products water pump 8 sets No. two connection of backwash pipeline 10 1# and produces on front side of water pump 7, one, No. two Backwash pipeline（9、10）On be provided with 1#, 2# backwash valve（13、14）, 1# produces water pump 7 and No. two backwash pipelines on No. 1 water producing pipe 9 It is provided between 10 on 11, No. 2 water producing pipes 6 of stop valve and is provided with stop valve 11,1 between 2# product water pumps 8 and a backwash pipeline 10 A rear side of backwash pipeline 9 is provided with check valve 12,1# and produces No. two backwash pipelines on 15, No. 2 water producing pipes 6 of water valve on water producing pipe 9 10 rear sides are provided with check valve 12,2# and produce water valve 16.1#MBR films group 2.1, the connection aerated conduit of 2#MBR films group 2.2.

Embodiment 2：A kind of novel all-in-one alternative expression A-MBR bioreactor for treatment methods, make 1#, 2# produce water during operation Pump（7、8）Often operation 8min stops 2min as a cycle, reciprocal operation, 1# is produced into water pump 7 and 2# produces the rule operation of water pump 8 Time period staggers, and any one is produced water pump and recoil, recoil are completed to it by another product water pump within the 2min time periods paused Interval time can adjust according to actual conditions.

Specific job step explanation：

Sewage is put into 1#MBR membrane cisternas and 2#MBR membrane cisternas after being processed by anaerobic pond, and 2 system system runs simultaneously, but work Time period staggers, and particularly may be divided into following 3 step：

First：Control 1# produces water pump 7,1# backwash valves 13 and opens, and runs 2 minutes；

Then：Control 1# produces water valve 15,2# product water pump 8,2# product water valve 16 and opens, and simultaneously closes off 1# backwash valves 13, runs 6 points Clock；

Finally：1# produces water pump 7,1# product water valve 15,2# product water valve 16 and closes, while opening 2# backwash valves 14, runs 2 minutes.

(explanation：The step of the above 3 was a cycle with 10 minutes, and each cycle is divided into 3 active sections, goes round and begins again.Refer to Time period rule table).
