The new type water treatment technology that reason unit combines.
This Technology has the following characteristics that (1) utilizes the precipitation in the direct substitution former activated sludge process of membrane filtration technique
Pond operation, it is achieved activated sludge and pollutant separate with water, simultaneously as in the crown_interception of film can make bio-reaction zone
Active mud content reach about 8000 ~ 12000mg/L and reach as high as 20000mg/L, be far longer than conventional activated sludge process
Mud recoverable amount (about 3000mg/L), thus the efficiency of its biochemical reaction is much larger than conventional activated sludge process；(2) general MBR
Use in technique mostly is ultrafilter membrane or micro-filtration membrane, and separation accuracy is far above the sedimentation method+common filtration (sand filtration or multimedium mistake
Filter) therefore its effluent quality the most excellent；By the film crown_interception to activated sludge, mud mud age and reactor water are cut off
Contact between the power time of staying, the mud longer clearance being conducive to nitrobacteria enrichment to improve ammonia nitrogen in age；(3) longer mud
Mud makes activated sludge internal generation endogenous respiration age, consumes some residual activated sludge, the therefore excess sludge production of this technique
Extremely low.
This technique remains in following obvious shortcoming at present: (1) film cost is high, makes film--the capital expenditure of bioreactor
Higher than traditional waste water treatment process；(2) fouling membrane easily occurs, makes troubles to operation management；(3) service life of film is short,
Film is changed and is caused process operation depreciation of equipment huge；(4) energy consumption is high compared with general technology: first MBR mud-water separation process is general
Use negative pressure-pumping, need certain power consumption；Next to that in order to keep membrane flux, alleviate fouling membrane, it is necessary to increase two-phase flow speed,
Washing away film surface, the energy consumption causing MBR is higher than traditional biological treatment.

Detailed description of the invention
The technical scheme of a kind of spontaneous membrane bioreactor of this utility model described the most in detail:
A kind of spontaneous membrane bioreactor, including equipment box 1, side, equipment box 1 outer the inside is provided above into water
Mouth 2, is provided with outlet 12 below opposite side；The lower section of equipment box 1 is provided with supporting leg 7；Equipment box 1 is internal in water outlet
Water collecting chamber 11 is produced in being provided with of the side of mouth 12, produces water collecting chamber 11 and is connected with outlet 12；Equipment box 1 is internal to be also set up
There is central canal 8；Central canal 8 side connects actively solid shafting 5；Actively solid shafting 5 is through the side of equipment box 1, by setting
The bearing 4 put on supporting leg 7 is fixed, and is actively sealed by mechanical sealing member 6 inside solid shafting 5 and equipment box 1；Center
Pipe 8 side connects passive solid shafting, is fixed by the bearing 4 being arranged on supporting leg 7, passive solid shafting and product water collecting chamber
Sealed by mechanical sealing member 6 outside 11；Actively solid shafting 5 by drive disk assembly 3 by driving motor 13 to drive and rotate, and
Central canal 8, passive solid shafting is driven to rotate；It is provided with film bio-disc 9 on described central canal 8；Described film bio-disc 9 by
Biofilm support layer, biological membranous layer are constituted.
During this utility model a kind of spontaneous membrane bioreactor work:
Driving motor 13, according to needs, by drive disk assembly 3, power is delivered to actively solid shafting 5 drives whole film biological
Disk 9, central canal 8, passive hollow axle 10 are with the rotational speed set.
First sewage passes through water inlet 2 access arrangement casing 1 and on continuous tunicle bio-disc 9 in equipment box 1
The microbial cleaning of attachment.Sewage after purification under the effect of malleation head by the layer of support material of film bio-disc 9 and
Flow into central canal 8 after the filtration of biological attachment layer, collect the passive hollow axle 10 of inflow via central canal 8 and be finally pooled to produce water receipts
Collection room 11 is also flowed out by outlet 12.
Spontaneous membrane bioreactor works when, film bio-disc 9 constantly rotates, the part table being exposed in air
Face contacts with the oxygen molecule in air and obtains supplementing and forming aerobe reaction environment of dissolved oxygen, is divided by aerobic microbiological
Solve organic pollution and ammonia nitrogen and organic nitrogen are converted into nitrate or nitrite by nitration reaction.And it is immersed in liquid level
Below partially due to enough dissolved oxygen cannot be obtained form anaerobism or anaerobic environment, by anaerobism health without decomposing organic contamination
The nitrogen of the NO3-N and NO2-N state in sewage is also reduced to harmless nitrogen discharge and realizes biological denitrificaion by thing.Along with film is raw
The rotation of thing disk 9, is exposed to the part of air surface and will be partly dissolved oxygen and air bubble is brought in the sewage of reactor, with
The increase of disc rotation speed, the most for the dissolved oxygen supplemented in sewage, thus reaction can be controlled by controlling the rotating speed of disk
The dissolved oxygen concentration of sewage in device, thus realize controlling biological macroscopic view aerobic environment, finally make sewage be purified and reach pre-
If effluent standard.
