Object, insoluble organic matter are converted to dissolved organic matter；
D) treated in hydrolysis acidification pool, and waste water flows into progress Air Exposure in contact-oxidation pool, and utilizes catalytic oxidation
Life assemblage filler in pond removes the BOD of waste water and absorbs the phosphorus in water, and the effluent part in contact-oxidation pool is back to
In hydrolysis acidification pool, other waste water then flow into secondary settling tank；
E) waste water is separated into supernatant and sediment by secondary settling tank, and supernatant inflow continuous membrane filter is processed into can be again
The water utilized, partly precipitated object, which is back in hydrolysis acidification pool, carries out denitrification processing, and other sediments are discharged into sludge condensation
Pond carries out Air Exposure；
F) sediment isolated in sludge concentration tank is dehydrated by plate and frame filter press, and the overflow of sludge concentration tank
The filtrate of liquid and plate and frame filter press, which drains into conditioning tank, to be reprocessed.
Specifically, in step e), the continuous membrane filter is the device using inorganic ceramic membrane for filtering membrane tube.
Specifically, in step d), the life assemblage filler is by plastic circle ring and tow groups at plastic circle ring is by outer
Outer ring and inner ring form, and fibre bundle connects the outer ring for being distributed in plastic circle ring, and active microorganism, plastics circle are attached on fibre bundle
The inner ring of ring is equipped with several branches.
Specifically, the fibre bundle is hydroformylation fiber or dacron thread.
Specifically, air air-lift device is connected between the secondary settling tank and hydrolysis acidification pool.
Specifically, aerating system is equipped in the sludge concentration tank.
The beneficial effects of the present invention are: being blocked the present invention provides a kind of method for handling sanitary sewage by grid pond
Cut rubbish.By conditioning tank to waste water pre-exposure gas disposal.By hydrolysis acidification pool by waste water suspended matter and solubility it is organic
Object is hydrolyzed to organic acid.It is waste water removal BOD by contact-oxidation pool and absorbs phosphorus.By continuous membrane filter by waste water mistake
Filter is the water that can be utilized again.The water that the application can utilize sanitary wastewater processing again, to realize following for water
Ring utilizes.
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, the sanitary wastewater from residential block enters grid pond progress rubbish intercept process.
Then the waste water in grid pond is pumped into conditioning tank, while blasting air and preaeration is carried out to waste water in conditioning tank
And stirring, homogeneous is mixed, effectively reduction impact load, to play the protective effect to subsequent processing units, avoided insoluble outstanding
It accumulates and ferments in floating object pond, it can also stripping oxidation low molecule organic matter.
Then the waste water in conditioning tank flows into hydrolysis acidification pool.High-performance bio gimp formula filler is put in hydrolysis acidification pool,
The suspended matters such as starch, fiber, carbohydrate in waste water and dissolved organic matter are hydrolyzed to organic acid, keep macromolecular organic
Object is decomposed into small organic molecule, and insoluble organic matter is converted to dissolved organic matter, and heterotrophic bacteria is anti-under anoxic conditions
NO3- is reduced to molecular nitrogen (N2) and completes the circulation of C, N, O in ecology by nitrification, realizes sewage harmless treatment.Water
From flowing to, contact-oxidation pool is interior to carry out biochemical treatment to waste water in solution acidification pool.
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.
It is enlightenment with the above-mentioned desirable embodiment according to invention, through the above description, relevant staff is complete
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention'.This invention it is technical
Range is not limited to the contents of the specification, it is necessary to which the technical scope thereof is determined according to the scope of the claim.
