Abstract
The invention discloses a kind of methods for handling aramid waste water, comprising the following steps: aramid waste water is passed through anaerobic reactor Ph and is adjusted to 7.5 ~ 9.5, Facultative Halophiles are added and carry out two-stage anaerobic biochemical reaction, every 48 ~ 60h of order reaction；By treated, waste water Ph is adjusted to more than or equal to 11, carries out ammonia-nitrogen desorption to Ph not less than 10 into ammonia-nitrogen stripping tower, and no longer decline；Above-mentioned processed waste water is imported into aerobic reactor Ph and is adjusted to 7 ~ 9, Facultative Halophiles are added and carry out aerobic reaction, 20 ~ 30h.Compared with prior art, the present invention methodological science is simple, easy, high treating effect is designed.It is handled due to introducing microorganism, overall procedure when treating wastewater, can save very big energy consumption, treatment cost is greatly saved, and meet the requirement of aramid fiber industry producer process for producing waste water.
Description
Technical field
The invention belongs to environment protection fields, and in particular to a method of processing aramid waste water.
Background technique
N,N-dimethylacetamide (DMAC) is widely used, in aramid fiber as excellent organic solvent in aramid fiber industry
Production process in will generate largely containing the waste water of DMAC.The characteristics of waste water, is: COD high (>=10000mg/L), salt content
High (2%~3%), total nitrogen are high and are organic nitrogen, are one of difficult organic wastewater.
Currently used processing method are as follows: recycled in waste water in the form of extraction fractional distillation or evaporation+rectifying
DMAC and using iron-carbon micro-electrolysis+Fenton come the DMAC in degrading waste water.But use extraction fractional distillation or evaporation+rectifying
Form is bigger to recycle the DMAC energy consumption in waste water, and still contains a certain amount of DMAC in waste water after the recovery, is discharged into water body
In will cause water pollution；Using iron-carbon micro-electrolysis+Fenton, come the DMAC in degrading waste water, then treatment effect is undesirable, and handles
Higher cost.Above-mentioned existing technology shows that the processing of DMAC in aramid fiber production waste water is still a problem.
Summary of the invention
Goal of the invention: in view of the above-mentioned deficiencies in the prior art, it is an object of the present invention to provide a kind of aramid waste water processing method.
Technical solution: in order to achieve the above object, the present invention is specifically achieved like this: a kind of processing aramid waste water
Method, comprising the following steps:
(1) aramid waste water is passed through anaerobic reactor Ph and is adjusted to 7 ~ 10, Facultative Halophiles are added and carry out two-stage anaerobic biochemical reaction, often
48 ~ 60h of order reaction, the additional amount of Facultative Halophiles are the 10%~15% of anaerobic reactor volume；
(2) it will be adjusted to by the waste water Ph of step (1) processing more than or equal to 11, carry out ammonia-nitrogen desorption extremely into ammonia-nitrogen stripping tower
Ph is not less than 10, and no longer declines；
(3) oxidation reactor is imported to step (2) treated waste water, and Fenton reagent is added and is aoxidized, Fenton reagent adds
Enter 1 ~ 2% that amount is wastewater volume；
(4) flocculation filtration, the collection cake of press generated step (3) is handled, standard emission of clear.
Further, the salt-durable microbe are as follows: gluconobacter oxydans, halo micrococcus luteus, produce alkali vacation unit cell at micrococcus luteus
Bacterium causes golden pseudomonad, riboflavin pseudomonad, pseudomonas putida or Pseudomonas facilis.
Further, the reagent for adjusting Ph is sulfuric acid or sodium hydroxide.
The utility model has the advantages that designing easy, high treating effect compared with prior art, the present invention methodological science is simple.Due to drawing
Enter microorganism to be handled, overall procedure when treating wastewater, can save very big energy consumption, be greatly saved improvement at
This, meets the requirement of aramid fiber industry producer process for producing waste water.
