Technical field
The present invention relates to a kind of tow method of wastewater treatment, belongs to field of waste water treatment.
Background technology
Tow waste water mainly has two strands, and wherein one is normally intake for waste water station, and continuous discharge, major pollutants are second
The material such as cellulose produced in alcohol, acetic acid, ethyl acetate, secondary cellulose acetate sheets, phosphate, a small amount of benzene and production process, its feature is
It is 5000 ± 500mg/l that inlet flow-patterm is 4-5, COD, and organic pollution concentration is higher, containing in sub-fraction benzene and production process
The intermediate products (cellulose acetate etc.) that does not collect completely, other pollutant good biodegradability.Another strand of waste water is highly concentrated
Degree waste water, interval discharge, major pollutants are waste liquor, and it is 1-3 that COD is 20000 ± 2000mg/l, pH.
The existing technology for processing tow waste water is waste water-neutralization reaction pond-aeration and biological pond-flocculation sedimentation tank-water outlet.Deposit
Problem as follows：
(1) before waste water enters biochemical system, pH need to be added lime to adjust to 6～9, causes chemical feeding quantity and sludge quantity greatly, after
The problems such as continuous pipeline configuration, annual neutralization medicament expense about 1,000,000 or so.
(2) treatment effeciency is low, effluent quality COD≤300mg/L.
Content of the invention
The invention aims to above-mentioned technical problem is solved, a kind of tow method of wastewater treatment is provided.
The purpose of the present invention is achieved through the following technical solutions.
A kind of tow method of wastewater treatment, comprises the following steps that：
Step one, low concentration wastewater and high-concentration waste water are uniformly squeezed in regulating reservoir by pump, obtain mixed waste liquor；Need
Ensure the COD in mixed waste liquor in 8000mg/L or so, pH 3.5～4.5 or so；
Step 2, the mixed waste liquor of step one are entered in immobilization Black Liquor with Efficient Bacteria biochemical treatment tank, are given birth in immobilization Black Liquor with Efficient Bacteria
Change easy biochemical degradation material of degrading in processing pond, after improving wastewater pH；Subsequently into hydrolysis acidification pool, the material of difficult degradation is dropped
Solve as after easy biochemical degradation material, entering after contact-oxidation pool removal remainder COD, flocculation sedimentation tank is entered, is gone further
Except COD in waste water.
Black Liquor with Efficient Bacteria in the immobilization Black Liquor with Efficient Bacteria biochemical treatment tank is photosynthetic bacteria；
With catalytic oxidation microorganism in the contact-oxidation pool；
Beneficial effect
The method of operation of the neutral water inlet of the biochemical system that the 1st, breaks traditions, the acid water inlet of biochemical system, save a large amount of neutralization examinations
Agent expense, it is to avoid N-process produces a large amount of sludge and Incrustation of pipe phenomenon.
2nd, wastewater treatment COD removal effect is improved.
Description of the drawings
Fig. 1 is the process chart of embodiment 1.
Specific embodiment
The invention will be further described with embodiment below in conjunction with the accompanying drawings.
Embodiment 1
A kind of tow method of wastewater treatment, comprises the following steps that：
Step one, low concentration wastewater and high-concentration waste water are uniformly squeezed in regulating reservoir by pump, obtain mixed waste liquor；Need
Ensure the COD in mixed waste liquor in 8000mg/L or so, pH 3.5～4.5 or so；
Step 2, the mixed waste liquor of step one are entered in immobilization Black Liquor with Efficient Bacteria biochemical treatment tank, are given birth in immobilization Black Liquor with Efficient Bacteria
Change easy biochemical degradation material of degrading in processing pond, the wastewater pH that pH is 3.5～4.5 is improved to 6～9 or so, dissolving need to be ensured
Oxygen is in 0.2～1mg/L；Subsequently into contact-oxidation pool.Remainder COD is removed using microorganism in contact-oxidation pool, need to protect
Card dissolved oxygen is between 2～6mg/L；Enter coagulative precipitation tank, add PAC in coagulative precipitation tank, chemical feeding quantity be mass ratio 1～
1.5 ‰ PAC, remove COD in waste water further, and final outflow water meets COD≤100mg/L requirement.
Immobilization Black Liquor with Efficient Bacteria in the immobilization Black Liquor with Efficient Bacteria biochemical treatment tank is：Using process for fixation be activated carbon
With flyash with volume ratio 1:After 1 mixing, the photosynthetic bacteria of 10 times of volumes is added, 10min is stirred every 2h, continue 1 day.To enter
Water is diluted to COD=2000mg/L or so, continuum micromeehanics, after stable water outlet, improves influent COD=4000mg/L, treats water outlet
After stable, influent COD=6000mg/L is improved, after stable water outlet, influent COD=8000mg/L is improved, after stable water outlet,
Complete immobilization Black Liquor with Efficient Bacteria culture.
With catalytic oxidation microorganism in the contact-oxidation pool, in contact-oxidation pool, filler is combined stuffing, contacts oxygen
Change microorganism in pond：With sludge seeding in the original aeration and biological pond of waste water station, immobilization Black Liquor with Efficient Bacteria biochemical treatment tank water outlet is passed through,
By the survival of the fittest, the microorganism for adapting to immobilization Black Liquor with Efficient Bacteria biochemical treatment tank water outlet stays, it is impossible to which accommodator is dead to be eliminated,
Ultimately form contact-oxidation pool microorganism；
Middle and high concentration wastewater equalization pond of the present invention act as the high-concentration waste water of collection interval discharge, mixes, it is ensured that
The subsequent processing units influent quality water yield is stable.
Perforated pipe air stirring is provided with regulating reservoir pond in main system, mixes water by air stirring, protect
Card subsequent processing units influent quality is stable.
1. service data
Table one
As seen from the above table, when system inlet flow-patterm is 4.12, after immobilization Black Liquor with Efficient Bacteria biochemical treatment tank, system pH is carried
8～9 are risen to, is neutralized without the need for feeding lime.Coagulating sedimentation system final outflow water is stable in below 100mg/L.
