Description
Technical field
The invention belongs to technical field of waste water processing, more particularly to a kind of advanced treatment method for printing and dyeing wastewater and device.
Technical background
Printing and dyeing enterprise is industrial wastewater discharge rich and influential family, and it has, and water is big, organic pollution content is high, colourity deep, alkalescence
Greatly, the features such as change of water quality is big, belongs to intractable industrial wastewater.Domestic conventional printing-dyeing waste water treatment process, main to divide at present
It is two major classes：One is physico-chemical process, and two is biochemical process.Due in recent years, a large amount of bio-refractory organic matters such as PVA slurries, artificial
Silk alkaline hydrolysis thing (mainly O-phthalic acids material), New-type adjuvant etc. enter dyeing waste water, and traditional biological treatment is
By serious challenge.In addition country improve constantly discharge water quality requirement, i.e., do not require nothing more than water outlet COD can reach 80mg/L with
Under, and total nitrogen can be controlled in below 15mg/L.
Various depth logos more popular at present have：BAF, advanced oxidation processes（Fenton, ozone）, physics
Absorption method and membrane separation technique etc..BAF operating cost is relatively low, but it is influenceed than larger by change of water quality；It is fragrant
The method of pausing needs regulation pH and adds a large amount of molysite, and salt content is higher in causing water outlet, is unfavorable for reuse, can also form a large amount of dirts
Mud, increases intractability；Absorption method mainly utilizes activated carbon, the loose structure of macroporous absorbent resin, carries out hard-degraded substance
Removal, investment is high, and operating cost is high.It is very good in operation early stage outlet effect, but with the adsorption saturation of activated carbon, water outlet effect
Fruit is gradually deteriorated, until system completely loses removal ability, it is necessary to be regenerated to activated carbon.And renovation process is complicated, regeneration
Number of times is limited, and it is secondary pollution to produce substantial amounts of useless charcoal.
Ozone has strong oxidizing property, and with sterilization, oxidation of organic compounds removes colourity, obtained in waste water is processed extensively
Application.But processed only by ozone and do not ensure that water outlet COD and total nitrogen can be up to standard.
Therefore, in order to solve the above technical problems, it is necessory to provide a kind of with denitrogenation but also the waste water of COD not only can be removed
Processing unit, to overcome the defect of the prior art.
The content of the invention
The technical problems to be solved by the invention be to provide one kind can make COD and the equal emission compliance of total nitrogen, processing cost it is low,
Run convenient advanced treatment method for printing and dyeing wastewater and device.Therefore, the present invention uses following technical scheme：
A kind of advanced treatment method for printing and dyeing wastewater, the described method comprises the following steps：
A. flotation tank is flowed into through the dyeing waste water after biochemistry, Polyferric Sulfate and PAM is added, to remove the organic matter of difficult degradation；
B. fibre turntable filter chamber is flowed into by the dyeing waste water after flotation tank treatment, to remove oil removal；
C. mixed pond soon is flowed into by the dyeing waste water after fibre turntable filter chamber treatment, this to mix and add mass fraction in pond and be soon
27.5% H2O2；
D. the dyeing waste water after being processed through too fast mixed pond flows into ozone contact tank and adds ozone, stops 1 hour；
E. flow into activated carbon filter from ozone contact tank bottom by the dyeing waste water after ozone contact tank treatment and add ozone,
Stop 30 minutes, with further degradation of organic substances；
F. flow into carbon source by the dyeing waste water after activated carbon filter treatment and add pond and denitrification filter pool, stop 15 minutes, with
Removal total nitrogen；
G. flowing into discharge bay by the dyeing waste water after denitrification filter pool treatment carries out outer row.
H2O2As oxidant addition in fast mixed pond, its oxidation effectiveness of the mass fraction of selection 27.5% is optimal, if being less than
Then oxidisability is weaker for the mass fraction, and security is relatively poor if more than the mass fraction.
On the basis of using above-mentioned technical proposal, the present invention can also be using technical scheme further below：
Methods described is further comprising the steps of：
The water of discharge bay discharge also can access activated carbon filter and denitrification filter pool is backwashed, and the waste water after backwash is again
Wastewater treatment is carried out, to realize reasonably utilizing water resource.
The ozone contact tank and the total ozone dosage of activated carbon filter are 50ppm, ozone contact tank and activated carbon filter
It is 3 to add ratio:2, ozone contact tank is respectively with 1:1:2 ratio adds ozone in three times.Add in three times and may be such that ozone
Waste water and the abundant adsorption reaction of ozone in contact chamber, reach optimal treatment effect.
