Detailed description of the invention
Embodiment mono-
As shown in Figures 1 to 4, a kind of self-loopa biomembrane denitrogenation sewage disposal device, comprise shell body 2,Aerator 1, aerobic packing area 11, anoxic packing area 5 and MBR membrane module 10.
In this embodiment. Described shell body 2 is the steel circular cylindrical tank body of a vertical placement, also canFor other regular shape tank bodies, as square, cuboid etc.
Be provided with aerator 1 in described shell body 2 inside bottom, described aerator 1 air-source fromRoots blower, aerator 1 comprises the aeration head that is arranged in tank base, described aeration head is evenly arrangedIn 11 bottoms, aerobic packing area, can provide sufficient air-source for aerobic microbiological like this.
Described aerobic packing area 11 is arranged on aerator 1 top, and the aerobic filler of this part hangs over aerobicOn filler support 42, described aerobic filler support 42 is fixed in center baffle 3, described center baffle 3It is first conical baffled 31 that below is also provided with, and this setting of first conical baffled 31, can make down on the one handIn the middle of the air that side's aeration head is emitted concentrates on, be convenient to, for aerobic microbiological provides oxygen, on the other hand canEnough allow the sewage that flows down from anoxic packing area 5 herein pressure increase, and form between aerobic packing area 11A pressure differential, is convenient to Hydraulic Circulation.
11 tops, described aerobic packing area are provided with MBR membrane module 10, can play the effect of mud-water separation.Described MBR membrane module 10 is connected with outlet pipe 9, and described outlet pipe 9 is connected with self priming pump, for inciting somebody to actionProcessing water is discharged.
Centered by described MBR membrane module 10, support 4 is all arranged in surrounding and bottom, described support 4Comprise anoxic filler support 41 and aerobic filler support 42, described MBR membrane module 10 belows are provided withAerobic filler support 42, hangs and is fixed with aerobic filler on described aerobic filler support 42; Described MBRMembrane module 10 surroundings are provided with anoxic filler support 41, and in order to carry out anoxic packing area and MBR film groupThe isolation of part 10, between is provided with center baffle 3.
For ensureing the Hydraulic Circulation of whole equipment, MBR membrane module 10 is connected with anoxic packing area 5,In reserved water hole hole, the top of center baffle 37.
In the time that equipment internal upper part build-up of air is more, for avoiding occurring pressure imbalance situation, outside this equipmentHousing 2 tops are provided with steam vent 8. Also be provided with water inlet pipe 6 on shell body 2 tops, consider that water distribution is equalEven, symmetrical on described shell body 2 tops.
Between shell body 2 and center baffle 3, be provided with anoxic filler support 41, this region is that anoxic is filled outMaterial district 5, hangs and is fixed with anoxic filler on described anoxic filler support 41.
Be illustrated in figure 2 the section plan of this sewage-treatment plant; Centered by MBR membrane module 10,Surrounding is provided with ring support 4, on described support 4, is hung with filler, at described MBR membrane module 10Below is provided with aerobic packing area 11, below described aerobic packing area 11, is provided with aerator 1, instituteThe aeration head of stating aerator 1 is also evenly distributed on aerobic packing area 11 centered by MBR membrane module 10Below.
As shown in Figures 3 and 4, in the process of Hydraulic Circulation, due to the existence of aeration zone, cause skyGas constantly enters, and the density of this part does not have the region of aeration lower than surrounding, forms density contrast, closeUnder the motive force of degree difference, sewage is constantly collected to aeration zone by anoxic packing area, and at air-lift unitAnd under the drive of Hydraulic Circulation, continue through aerobic packing area, the pollutant in sewage is through aerobic micro-lifeAfter thing is processed, via the mud-water separation effect of MBR membrane module 10, clear water continues upwards, and mud quiltHold back, the mud of being held back by MBR membrane module 10 under the effect of backwash will fall back to aerobic packing areaOn 11 fillers, and a clear water part is siphoned away by self priming pump, a part by cross water hole get back to anoxic zone withThe sewage newly entering, the flow process before repeating.
Embodiment bis-
As shown in Figure 5, be with the difference of embodiment mono-, at described MBR membrane module 10 and goodBetween oxygen packing area 11, be provided with second conical baffled 32, by second conical baffled 32 design, oneAspect can converge to current MBR membrane module 10 places, produces certain pressure differential at this place, anotherAspect, due to the design of conical in shape, can reduce mud and be attached on MBR film, under the impact of currentMore easily fall after rise to aerobic packing area 11.
Working method, the operation of this self-loopa biomembrane denitrogenation sewage disposal device comprises two parts, theA part be sewage at intrasystem continuous circulation, sewage is from water inlet 6 access arrangement inside, this partSewage enters the rear continuation in anaerobic packing area 5 and down flows, because causing air, the existence of aeration zone 1 enters,The density of this part is less than both sides and does not have the density of the anaerobic packing area 5 that gas enters, due to density contrastEffect, makes the sewage on both sides to intermediate flow, therefore forms a waterpower circulation, as shown in Figure 3.
Part II is intermittent water inflow and the intermittent drainage of system, and system is intake by programme-control, backwashIn time, stops into water; Water outlet need be passed through the processing of MBR membrane module, when one section of the every operation of MBR membrane moduleBetween just need to carry out backwash so that it recovers filtering function, the operation of MBR membrane module time is arranged by self priming pumpWater, therefore the water outlet of system is intermittent. MBR system operation be divided into taking 30min as one-period withLower several stages:
1. the system operation phase: now intake pump is opened, and backwashing pump is closed, self priming pump is opened, system water inlet,Water outlet, time 13min.
2. film relax stage: now intake pump is opened, and backwashing pump is closed, and self priming pump cuts out, system water inlet,
3. repeat the first stage.
4. repeat second stage, the time is 0.5min.
5. in the backwash stage: now intake pump is closed, backwashing pump is opened, and self priming pump cuts out, system do not intake,Not water outlet, backwash water inlet, time 1min.
6. repeat fourth stage.
Described intake pump is connected with water inlet pipe 6, and for the access arrangement of sewage, described backwashing pump is used forCarry out the backwash of MBR membrane module 10, remove the mud that MBR film is held back, described self priming pump withOutlet pipe 9 is connected, for processing water device for transferring.
Except the technical characterictic described in description, be the known technology of those skilled in the art.
