Description
Technical field
The present invention relates to a kind of processing systems of inorganic salts in removal wastewater of steel industry, belong to useless in environmental protection
Water treatment field.
Background technique
Low-carbon warp under the background of Global climate change and energy shortages, based on low energy consumption, low pollution, low emission
Ji development model is just taken seriously, and the section that steel and iron industry is advocated as high energy consumption, multiple rows of industry put in global low-carbon economy
Great responsibility can be carry in the work of emission reduction.
It is important to have become one for leading world steel industrial for basic industry of the steel and iron industry as China's industrial development
Strength, the scale and growth momentum of China's steel industry enable the world attract attention.But steel and iron industry is both with water rich and influential family and blowdown
Rich and influential family, with the rapid development of modernization industry, the problems such as water consumption sharp increase, shortage of water resources, serious water pollution, it has also become I
The bottleneck of state's development of iron & steel industry.Solve the problems, such as this, it is most direct, most economical at present, also most effective approach is exactly to study
Develop the purification treatment technology of a whole set of advanced wastewater of steel industry.
Wastewater of steel industry purification treatment technology and equipment research work are a great Social benefit and economic benefits
Work, but in the wastewater treatment process of iron and steel enterprise, if being not provided with desalting processing technique, waste water salt content meeting that treated
It is very high, if such waste water as recirculated water after high power is concentrated, one of the various ion concentrations increase, and can generate a series of objects
Reason, chemical change lead to pipe-line system corrosion and fouling, seriously affect the normal operation of equipment, and shorten the use longevity of equipment
Life.
Currently, the desalting technology of China's wastewater of steel industry mainly includes ion-exchange, double film desalination methods and Electro Sorb
Three kinds of desalination method.
(1) ion-exchange:
Ion-exchange is a kind of effective water treatment technology of maturation, and desalting effect is preferable.But there are equipment for this method
It takes up a large area, the frequent complicated, effluent quality of system operation maintenance is in the defect of cyclic fluctuation, and needs to add flocculant
With a large amount of soda acid of consuming, it is easy to produce secondary pollution, is unfavorable for the protection of ecological environment.
(2) double film desalination methods:
Double film desalination methods are primarily referred to as the treatment process of ultrafiltration+reverse osmosis, which is mainly produced using membrane separation technique
Desalted water.
Ultrafiltration principle is a kind of membrane separating process principle, using organic or inorganic ultrafiltration membrane, under the action of ambient pressure
The substance of colloid, particle and macromolecule in trap water, and hydrone and small particles of solute can penetrate ultrafiltration membrane.Work as water
After ultrafiltration membrane, the most of colloidal silicon contained in water can be removed, while can remove a large amount of organic matter etc..It is reverse osmosis to be
Separate the solvent in solution by reverse osmosis membrane with enough pressure, the direction phase of this process and naturally osmotic
Instead, because referred to herein as reverse osmosis.
Double film desalination methods have many advantages, such as to produce water quality height, automatically control degree height, easily operated control.But the party
Method there is also requiring the disadvantages of high, impact resistance is small, membrane damage is not easily repaired to influent quality, meanwhile, embrane method water outlet makes
With being needed in the process using chemical agents such as a large amount of antisludging agents.
(3) electro-adsorption demineralization method:
Electro-adsorption demineralization technology is a kind of emerging water purification technology, the basic principle is that using brackish water anodic-cathodic it
Between flow, water intermediate ion is by respectively to the electrode transfer of oppositely charged when energization, and by the electrode adsorption in electrode surface shape
At electric double layer.It is concentrated as ion/charged particle is enriched in electrode surface, dissolved salts, colloidal solid and other bands in water
The concentration of isoelectric substance substantially reduces, to realize the desalination of water, go hardness and purification.It only needs to be shorted electrode, quilt when regeneration
The ion of absorption is discharged from electrode surface again, and electrode is regenerated.
Electro-adsorption demineralization method is people because of practicability with higher and the wider scope of application, lower processing cost
It is of interest.Field is utilized in steel and iron industry recirculated water desalting processing, Sewage treatment, before Electro Sorb technology has a wide range of applications
Scape.But there is also shortcomings, such as desalting efficiency to need to be further increased for electro-adsorption demineralization technology, electrode is from when regenerating
Between it is longer, typically constitute from the one third of whole cycle, influence producing water ratio.
Currently, in existing processing wastewater of steel industry inorganic salts method there are occupation area of equipment big, system behaviour
Make to safeguard that frequently complicated, impact resistance is small, equipment is easy to damage, desalting efficiency is low, can generate secondary pollution problems.Therefore,
It is necessary to get rid of existing processing technique thinking, the new way of processing steel and iron industry brine waste is hewed out, and then develops one kind
The processing technique of inorganic salts in the wastewater of steel industry of new type.
