Description
Technical field:
The utility model relates to a kind of small-sized pickle liquor second level membrane treatment appts, belong to three industrial wastes processing technique neck
Domain.
Background technique:
A large amount of pickling waste waters for being rich in Cr and Ni that plating, stainless steel production field can generate in process of production, it is such
The inorganic acid component of waste water is mainly nitric acid and hydrofluoric acid.Nitrate nitrogen is discharged into water, can cause the eutrophication of water body.Fluorine element
It can have an effect with a variety of enzymes in animals and plants, cause metabolic disorder, cytomorphosis, necrosis, sclerotin can also be caused excessive
There is spur, spinal canal stenosis and carcinogenesis in calcification.Therefore, pickling waste waters need to carry out at resource utilization and deep purifying
Manage it is up to standard after can be discharged into environment.
The processing of existing pickling waste waters uses substantially: aeration neutralizes, the method for precipitating, since conventional method only takes place into account
Qualified discharge is managed, so operating cost is excessively high, and the sludge pressed dry is often due to mishandling be easy to cause the secondary dirt of heavy metal
Dye, results in waste of resources simultaneously.Improvement to nitric acid, hydrofluoric acid waste liquid, American-European, De Deng state have all carried out many research works
Make, the method generallyd use has chemical method, evaporation, ion-exchange and solvent extraction etc..Chemical method, which can be recycled, some to be had
With substance, but technique is numerous and jumbled, and equipment is more；It is progress that fixed bed is changed to thermopnore by ion exchange, but that there is also spent acid is dense
Contracting and dilute acid pretreatment problem；The advantages of solvent extraction is consuming little energy, and equipment, material easily choose, but the rate of recovery of acid
It is low.Patent (201510180241) disclose a kind of stainless steel acid-washing waste liquid processing and iron, chromium, nickel recovery method, can be with
The separation of iron, chromium, nickel is realized to a certain degree, but there are nitration mixture to recycle, the nitre state in the ammonia nitrogen and solution that are newly added into
Nitrogen causes greatly to bear to subsequent water process, antacid the problems such as neutralizer dosage is big, at high cost in the process, traditional method
It is difficult to realize the high efficiente callback of valuable resource and the advanced treating of waste water, the utility model technology can realize the high efficiente callback of acid；
The consumption of alkali in subsequent processing is reduced, sludge output is small, improves the recycling benefit of the pickling waste waters in fields such as plating, stainless steel production
With can not only reduce environmental pollution, moreover it is possible to obtain considerable economic benefit.
Utility model content:
The purpose of this utility model is in view of the problems of the existing technology provided at a kind of small-sized pickle liquor secondary membrane
Device is managed, can not only realize the high efficiente callback of nitric acid, hydrofluoric acid nitration mixture, and sludge quantity may be implemented and greatly reduce, is run
Reagent cost substantially reduces, and the outward transport disposition expense of sludge greatly reduces.
Above-mentioned purpose is achieved through the following technical solutions:
A kind of small-sized pickle liquor second level membrane treatment appts, which is characterized in that successively include waste water tank, ceramic membranous system,
Intermediate water tank, nanofiltration membrane system, concentrated water processing system, the waste water tank pass through stainless steel pipes and pottery by centrifugal multistage pump multiple centrifugal pump
Porcelain membranous system is connected, and ceramic membrane produces water and is connected to intermediate water tank through stainless steel pipes, and the intermediate water tank is passed through through stainless steel pipes
High-pressure pump is connected with nanofiltration membrane system, and nanofiltration membrane system produces water and is connected to reuse water tank through stainless steel pipes, and reuse water tank is equipped with
Acidometer and automatic acid supplementing apparatus；The ceramics membranous system concentrated water and nanofiltration membrane system concentrated water enter concentrated water processing system；It is described
Ceramic membranous system and nanofiltration membrane system are respectively provided with inlet gage, discharge pressure table and flowmeter；The nanofiltration membrane is using acidproof
Nanofiltration membrane；The stainless steel pipes use antiacid corrosion-resistant stainless steel pipeline.
The utility model has the beneficial effects that
The system not only can be reduced hydrofluoric acid and additive amount when nitric acid in production, remove most of heavy metal contaminants,
The dosage of alkali in subsequent concentrated water treatment process can also be reduced, sludge yield is reduced, reduces sludge treatment expense, is optimized at waste water
Manage cost.
