Description
Technical field
Sewage treatment area is the utility model is related to, relates in particular to a kind of dye wastewater treatment device.
Background technology
Dye industry is the important foundation industry of Chinese society economy, and product scope is than wide, but DYE PRODUCTION has
It is wide in variety, batch less, updating decision the characteristics of, dye product in process of production have complex process, yield poorly down, composition it is multiple
Miscellaneous, the features such as waste water from dyestuff is more, the base stock of DYE PRODUCTION are benzene series, naphthalene system, anthraquinone, aniline and diphenyl amine compound,
And the material such as more and metal, salt chelates in production process, causes waste water from dyestuff " three high and one low " (high COD, NH3-
N and TN, high chroma, high salinity, low BOD5/COD) the characteristics of, there is serious threat, traditional life to human body, environment etc.
Thing handling process is extremely difficult to good treatment effect.One side waste water from dyestuff can cause dissolved oxygen in water body to reduce, and make water body
Light transmittance declines, and the growth to aquatile and microorganism is impacted, then the self-purification capacity of water body had an impact, finally
Water ecosystem can be caused to be seriously damaged；On the other hand, azo, anthraquinone and triarylmethane are included in waste water from dyestuff
Deng can make one carcinogenic, include inorganic heavy metal ion, such as Fe, Ni, Cr, As, Pb etc. in waste water in addition and be discharged into water body
In, aquatic ecosystem is not only broken up, and it is straight by that can be produced the methods of drinking water, skin contact and food chain to human health
Connect or indirectly influence, and then trigger human body minamata disease, Itai-itai diseases etc., result even in death.
Specifically, waste water from dyestuff feature includes the following aspects：
(1) it is using aromatic hydrocarbons and heterocyclic compound as parent etc. mostly, with colour developing group and polar group, colourity is high, place
Reason is got up cumbersome；
(2) concentration of organic matter is at a relatively high (high COD), and structure is more complicated, although in waste water partial organic substances be can
Biochemical, but B/C ratios are totally relatively low, biochemical poor, some of materials even also have toxic action to microorganism；
(3) dyestuff can produce substantial amounts of NH in production4Cl、NaCl、Na2SO4It is higher Deng inorganic salts, salt content；
(4) because DYE PRODUCTION is intermittent operation, wide in variety and batch is small, and waste water is discharged by phased manner, so water quality
Water change is bigger；
(5) toxicity is larger.Waste water from dyestuff includes the chemical substances such as halides, nitro compound, aniline and phenols, carries
Toxicity, it can not be degraded by microorganisms；
(6) there are the heavy metal ion such as a certain amount of suspended particulate, Fe, Ni, Cr, Pb, can be to people if do not dealt carefully with
Body, environment damage.
(7) ammonia nitrogen and total nitrogen content of material are high in waste water, and Determination of Total Nitrogen in Waste Water material is mainly by organic amine and heterocycle or more
Ring itrogenous organic substance forms, and for these materials after anaerobic reaction, the organic nitrogen in waste water can change into ammonia nitrogen substances, and processing is highly concentrated
The waste water of degree ammonia nitrogen must have rational technique, reasonably control sludge age, sludge age is too short can not to be enriched with nitrobacteria, mistake
It is long to cause sludge aging again, it can not effectively remove ammonia nitrogen.Secondly it is to turn alkali compounds that ammonia nitrogen concentration, which is converted into nitrate nitrogen,
Highly acid compound is turned to, the nitrification of ammonia nitrogen will consume a certain amount of basicity.If do not adopted an effective means, control basicity consumes,
PH will be caused significantly to decline, so as to cause aerobic microbiological and nitrifier to be suppressed.
To sum up, it is extremely difficult to good treatment effect during traditional biological treatment processing waste water from dyestuff.Existing prevalence
Processing method be set regulating reservoir+materialization+A2/O PROCESS FOR TREATMENT waste water from dyestuff.Its shortcoming has：First, not anti impulsion load,
Operational control is difficult, is extremely difficult to processing intent；Second, containing certain poisonous and harmful class material in waste water, it is not preprocessed will
Fatal influence can be produced to subsequent treatment process；3rd, the nitrification and denitrification reaction effect of this method is undesirable, particularly
It is low to TN clearance.4th, sludge quantity is big, and consumption of raw materials is high, cost increase.5th, there is (1) energy in traditional A2/O techniques
Consumption is high, and nitration reaction is aerobic process, and keeping needs to consume energy, and for Prepositive denitrification system, the setting of interior backflow also increases
Energy consumption；(2) there must be organic carbon source in denitrification process as electron donor, although in Prepositive denitrification system graywater
Organic matter as carbon source, if in waste water during C/N deficiencies, can also influence denitrification effect, rear-mounted denitrification system has to add
The additional carbons such as methanol, cause the wasting of resources；(3) nitration reaction is acid process, and anti-nitration reaction is production alkali process, in order to tie up
Hold the normal operation of system, it is necessary to additional substantial amounts of carbonic acid calcium alkalinity (sodium hydroxide or sodium carbonate), add operating cost.
