Description
Technical field
It the utility model is related to field of waste water treatment, and in particular to one kind is using electroosmose process processing dyeing waste water and reclaims
The device used.
Background technology
Textile printing and dyeing wastewater have the characteristics that water is big, content of organics is high, it is alkaline it is big, change of water quality is big, category is difficult
One of industrial wastewater.Dyeing is the larger department of China's discharge industrial wastewater, and its wastewater discharge accounts for textile industry and given up
The 80% of water discharge capacity.Conventional techniques of Dyeing Wastewater Treatment has biological degradation method, chemical oxidization method, flocculence, ion exchange
Method, decolorizing with activated carbon method, absorption method, ozone decolorization method etc..The water quality of dyeing waste water is with the kinds of fibers of processing and using technique
And the dye material used is different and different, contaminant component is widely different, and processing is difficult.
Supplementary material employed in dyeing.Chemical reagent and technology have quite big difference, but basic working procedure is
Quite similar.Two big pollution sources of dyeing waste water are desizing and dyeing (stamp) process, and they are in whole dyeing and printing process flow
Occupy very high proportion in caused waste water.High chroma, the characteristic of high-concentration hardly-degradable is presented in dyeing waste-water.
At present conventional method such as absorption method be using activated carbon, activated clay, ion-exchange fibre, bentonite, diatomite,
Cinder, flyash etc. have the adsorbent of absorption property, and absorption is carried out to the pigment in waste water, dyestuff and other harmful components
Remove.Traditional adsorbent can effectively remove dissolved organic matter in waste water, but can not remove the colloid in waste water and hydrophobicity dye
Material.The activated carbon dye molecule decolorizing effect small to molecular weight is preferable, to the decolorizing effect of macromolecule or hydrophobic dye compared with
Difference, while price height be present, regenerate the shortcomings of more difficult, integrated treatment expense is bigger than normal in charcoal absorption processing, at actual waste water
Seldom used in science and engineering journey.
Flocculence be applied in wastewater treatment most widely a technology, the technology are a certain amount of by being added into waste water
Flocculant, then using mixing, reaction, depositing technology, it is purified waste water.
Electrochemical purification processing dyeing waste water is carried out by electrode reaction, typically first by the print containing a large amount of dye molecules
Contaminate in the range of waste water regulation pH to 7~9, by an electrolytic cell, make negative electrode with iron, iron oxide or ferrous metal and be electrolysed
Reaction.In electrolytic process, into ferrous ion, they run into hydroxide ion caused by anode, that is, generate hydrogen-oxygen catholyte
Change iron precipitation, subsequent dye molecule and other organic matters are bonded in these bulky ferric hydroxide precipitates and sunk.Electrochemical process pair
Dyeing waste water containing acid dyes has preferable treatment effect, and percent of decolourization is up to 50%~70%, but to color is deep, CODCr is high
Disposal effect of dyeing wastewater it is poor.
Biological degradation method is the metabolism decomposing organic matter for utilizing microorganism in waste water, is that processing organic wastewater is most economical
One of effective method.It is different according to the aerobic requirement of microbial respiratory process, Aerobic Process for Treatment can be divided into and Anaerobic Treatment two is big
Class, specifically include activated sludge process, biomembrance process, oxidation pond process, anaerobic waste water and simultaneous oxygen biological treatment etc..
In a word, dyeing waste water is the difficult industry that a kind of water is big, colourity is high, complicated component, water quality mobility scale are big
Waste water.From the point of view of the present situation of China's dyeing water treatment technology, although by making great efforts for many years, a collection of practical technique has been obtained, has been solved
Determine many problems, but generally depositing without substantial breakthrough, the particularly factor such as equipment backwardness, unreasonable products structure
Aggravating the difficulty of governance of dyeing waste water.If waste water direct reuse after above-mentioned various biochemical treatments, can be because in production
Salt is too high and has large effect to the key index such as color fastness of printing and dyeing.
Water resource is increasingly in short supply at present, and the environmental consciousness enhancing of citizen, country also increasingly payes attention to energy-saving and emission-reduction.And print
It is huge to contaminate the industry waste water scale of construction, therefore is badly in need of a kind of dyeing waste water being handled to and effectively reclaimed the device used or set
