With.
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 oil separator, and waste water is adjusted after oil separator oil removal from inflow
Pond, while blasting air and preaeration and stirring are carried out to waste water in conditioning tank, homogeneous is mixed, effectively reduction impact load, to rise
To the protective effect to subsequent processing units, avoid accumulating and fermenting in insoluble suspended matter pond, it can also stripping oxidation low molecule
Organic matter.
The waste water in conditioning tank is then pumped into airfloat equipment, while the dosing coagulant in airfloat equipment with elevator pump
PAC (aluminium polychloride) and flocculant PAM (polyacrylamide) medicament, capture the indissolubility organic matter in waste water, and degradation is useless
Water COD.Air-flotation scum in airfloat equipment drains into sludge concentration tank via Slag Scraping Device, and waste water flows into hydrolysis acidification pool 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, living under aerobic condition
Property microorganism nitrification NH3-N (NH4+) is oxidized to NO3-, removal BOD, absorb phosphorus, and will treated effluent part
Flow back into denitrogenation in hydrolysis acidification pool.Other waste water in contact-oxidation pool 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
The penetrating fluid of wall just becomes recycling water.Secondary settling tank bottom sediment is periodically taken out partly precipitated object by air air-lift device
Enter to be back to hydrolysis acidification pool carry out denitrification, conducive to ammonia nitrogen in waste water removal and reduce sediment, another part sediment
It is discharged into sludge concentration tank, sets aerating system in sludge concentration tank, reduces sediment yield, plate using the endogenous respiration of microorganism
Frame filter press then carries out minimizing dehydration to sediment, and sediment periodically transports outward disposition after dehydration.The overflowing liquid of sludge concentration tank
And the filtrate of plate and frame filter press drains into conditioning tank and is handled again.
