Description
Technical field
The invention belongs to stainless steel manufacturing technology field, and in particular to a kind of stainless steel surfaces handle waste water flocculant.
Background technology
Stainless steel is widely used because of its excellent corrosion resistance and good outward appearance.Stainless steel in process of production,
Inevitably the oxide skin of black can be produced often by process, surfaces such as annealing, normalizing, quenching, welding.Oxygen
Changing skin not only influences the presentation quality of stainless steel, can also have a negative impact to the following process of product, therefore before following process
The surface treatment methods such as pickling, polishing must be used to be removed.All the time, it is caused a large amount of in producing stainless steel process
The processing of pickling waste waters is the problem of iron and steel enterprise.As steel and iron industry progressively develops, people gradually recognize that surface treatment is useless
Water is particularly the harm to mankind itself to environment, and stainless steel surfaces processing waste water is containing Cr6+ 、Cr3+With metallic iron, nickel
Acid waste water, Cr3+Belong to trace element in human body, participate in glucose and lipid metabolism.But Cr6+Have very big stimulation and
Corrosivity.Epidemiological study shows：Cr 6+Compound is common carcinogen, and inhaling people's abstracting moiety oxygen into blood makes
Hemoglobin becomes ferrihemoglobin, and red blood cell takes gas dysfunction, and interior suffocate occurs.When iron content waste water is discharged into water body, by
Oxygen has been seized in Yu Congshui, fish, animal and the life condition for participating in the microorganism of auto purification of water etc. has just been destroyed, causes fish
It is dead.Fluorine element can have an effect with a variety of enzymes in animals and plants, cause metabolic disorder, cytomorphosis, necrosis.Also can cause
Sclerotin is excess calcified to there is spur, spinal canal stenosis, and this method processing stainless steel surfaces processing waste water of carcinogenesis, although
To Cr6+Neutralize, reduced, precipitation process, the chromium sludge after filter press press filtration, still containing a small amount of Cr6+、Cr 3+,
Still there is larger harm to environment, antiseepage can only be used to fill.Because the toxicity of Cr VI is stronger, and can deposit steadily in the long term
, antiseepage landfill can not thoroughly eliminate the potential danger that high valence chrome damages to environment, and landfill can increase processing cost,
Take valuable land resource.Therefore, seeking more reasonably processing approach has important theoretical and practical values.
