Description
Technical field
The invention belongs to stainless steel manufacturing technology field, and in particular to a kind of stainless steel acid cleaning waste water biological 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 pickling waste waters pair
Environment is particularly the harm to mankind itself, and stainless steel acid cleaning waste water is containing Cr6+ 、Cr3+With metallic iron, the spent acidic of nickel
Water, Cr3+Belong to trace element in human body, participate in glucose and lipid metabolism.But Cr6+There are very big stimulation and corrosivity.Stream
Row disease is learned research and shown：Cr 6+Compound is common carcinogen, and inhaling people's abstracting moiety oxygen into blood becomes hemoglobin
Into ferrihemoglobin, red blood cell takes gas dysfunction, and interior suffocate occurs.When iron content waste water is discharged into water body, due to taking by force from water
Oxygen has been removed, has just destroyed fish, animal and the life condition for participating in the microorganism of auto purification of water etc., has caused fish dead.Fluorine member
Element can have an effect with a variety of enzymes in animals and plants, cause metabolic disorder, cytomorphosis, necrosis.Also sclerotin can be caused excessive
There is spur, spinal canal stenosis, and this method processing stainless steel acid cleaning waste water of carcinogenesis in calcification, although to Cr6+Carry out
Neutralize, reduce, precipitation process, the chromium sludge after filter press press filtration, still containing a small amount of Cr6+、Cr 3+, still have to environment
Larger harm, antiseepage can only be used to fill.Because the toxicity of Cr VI is stronger, and can exist steadily in the long term, antiseepage fills simultaneously
The potential danger that high valence chrome damages to environment can not be thoroughly eliminated, and landfill can increase processing cost, take the soil of preciousness
Ground resource.Therefore, seeking more reasonably processing approach has important theoretical and practical values.
