Detailed description of the invention
Invention will be further explained below with reference to the drawings and examples..
Fig. 1 is block schematic illustration of the invention；
Specific embodiment
Invention is described in further detail presently in connection with attached drawing.These attached drawings are simplified schematic diagram, only to show
Meaning mode illustrates the basic structure of invention, therefore it only shows and invents related composition.
Fig. 1 is block schematic illustration of the invention.
As shown in Fig. 1, from plant area, production waste water enters conditioning tank, while blasting air and carrying out to waste water in conditioning tank
Preaeration and stirring mix homogeneous, and effectively reduction impact load is avoided not with playing the protective effect to subsequent processing units
It accumulates and ferments in dissolubility suspended matter pond, it can also stripping oxidation low molecule organic matter.
The waste water in conditioning tank is then pumped into coagulation reaction tank with elevator pump, while adding coagulation in coagulation reaction tank
Agent PAC (aluminium polychloride) and flocculant PAM (polyacrylamide) medicament capture the indissolubility organic matter in waste water, degradation
Waste water COD.
Then waste water, which flows automatically, enters the separation that sedimentation basin carries out sediment and supernatant, goes air lift by sky after precipitate
Device is discharged into sludge concentration tank, and supernatant flows into hydrolysis acidification pool after collecting via sedimentation basin top periphery effluent weir certainly.
High-performance bio gimp formula filler is put in hydrolysis acidification pool, and starch, fiber, the carbohydrate etc. in waste water are hanged
Floating object and dissolved organic matter are hydrolyzed to organic acid, and larger molecular organics is made to be decomposed into small organic molecule, insoluble organic
Object is converted to dissolved organic matter, and it is complete to be reduced to molecular nitrogen (N2) by the denitrification of heterotrophic bacteria by NO3- under anoxic conditions
At the circulation of C, N, O in ecology, sewage harmless treatment is realized.Waste water in hydrolysis acidification pool is flow in contact-oxidation pool certainly
Carry out biochemical treatment.
Amplification quantity aeration tube built in contact-oxidation pool simultaneously overworks good life assemblage filler.The life assemblage filler be by
Plastic circle ring and tow groups are at plastic circle ring is made of outer ring and inner ring, and fibre bundle connection is distributed in the outer of plastic circle ring
It encloses, active microorganism is attached on fibre bundle, the inner ring of plastic circle ring is equipped with several branches.Branch is flakes.The flakes
Branch biofilm and can effectively cut bubble, improve the transfer rate and utilization rate of oxygen, aqueous vapor biomembrane is obtained
Sufficiently exchange, makes the organic matter in water obtain efficient process.
Aeration bubbles are fine and closely woven, and oxygen transfer efficiency is high, and under aerobic condition, the nitrification of active microorganism is by NH3-N
(NH4+) it is oxidized to NO3-, removal BOD, absorbs phosphorus, and effluent part flows back into denitrogenation in hydrolysis acidification pool by treated.It connects
Other waste water in touching oxidation pond lean on flow to secondary settling tank certainly.
Waste water is separated into supernatant and sediment by secondary settling tank, and the top periphery effluent weir of secondary settling tank collects supernatant gravity flow
Enter in the water tank of continuous membrane filter, using hydraulic pressure pressure, the penetrating fluid containing small molecule component is outside along direction normal thereto
Through the membrane tube tube wall of inorganic ceramic membrane, the muddy concentrate containing macromolecular components is retained by membrane tube, finally oozes out membrane tube pipe
