The pollution of other operation reactant liquors is caused, and then affects wiring board product quality, most circuit board plants dissolve hanger using nitric acid
Copper on surface, so as to the nitric acid waste of substantial amounts of nitric acid and cupric can be produced, if directly externally discharge needs substantial amounts of alkali
It is neutralized, causes substantial amounts of nitric acid to waste, while the presence of copper will also result in serious environmental pollution.
The technology for processing plating copper cash nitric acid strip waste liquid at present both at home and abroad mainly has chemical precipitation method, electrolysis, resin
Exchange process, evaporation concentration method and membrane separation process etc..In chemical precipitation method processing procedure, chemical feeding quantity is big, causes substantial amounts of Treatment of Sludge
It is costly；Electrolysis, resins exchange and membrance separation cost of investment are big, pretreatment high cost, complex operation；Evaporation concentration method energy consumption
Height, complex treatment process.All there is larger defect in the handling process for having adopted at present.
The content of the invention
Technical problem to be solved in the utility model is exactly to overcome not enough present in current technology, there is provided a kind of circuit
The regeneration complete set of equipments of plate factory electro-coppering wire holder nitric acid deplating liquid, separates and recovers the copper in nitric acid strip waste liquid, and nitric acid
Decoating liquid regeneration.
A kind of regeneration complete set of equipments of circuit board plant electro-coppering wire holder nitric acid deplating liquid, is characterized in that equipment mainly includes
Decoating liquid collecting tank, elevator pump, reactive tank, micro-filtration membrane feed pump, tube type filter membrance group, sludge-tank, slush pump, filter press
Machine, filtrate collecting tank, bag filter and medicine storage tank.
Collecting tank is connected to reactive tank by elevator pump, and reaction tank bottom is connected to tubular type microfiltration by micro-filtration membrane feed pump
Film group；Tube type filter membrance group top is connected to filtrate collecting tank by pipeline, and bottom is connected to sludge-tank by pipeline；Filtrate is received
Collection groove bottom is sequentially connected elevator pump, bag filter by pipeline and presss from both sides cylinder to production line nitre；Sludge-tank bottom passes through slush pump
It is connected to filter press；Medicine storage tank bottom is respectively connecting to the top of reactive tank, filtrate collecting tank by pipeline.
Furthermore, decoating liquid is discharged in collecting tank from workshop, is pumped in reactive tank through being lifted, in reactive tank
It is middle to add the stirring of the medicaments such as a certain amount of oxalic acid and flocculant, the copper in decoating liquid to generate cupric oxalate with oxalic acid reaction and flocculate heavy
Form sediment, reaction a period of time is entered in tube type filter membrance group by tubular type microfiltration pump filters.
Furthermore, the waste fluid inlet tube filtrate after membrane filtration that declines is entered in collecting tank, adds nitric acid and addition
Agent adjusts concentration of nitric acid, then the folder cylinder reuse of production line nitre is lifted after bag filter is filtered.
Furthermore, the sludge under micro-filtrate membrane filtration enters sludge-tank, then is entered in filter press by slush pump
Filter pressing is carried out, filter cake entrucking outward transport, pressing filtering liquid are processed in returning reactive tank.
The tube type filter membrance, membrane module employ the compound film tube of uniqueness, and which can not only remove the suspension for seeming dense
Solid, fiber etc., while antibacterial and some macromolecular substances can be removed, compare the long service life for having film, mistake with general film
Filter high precision, the pressure loss are less, and anti-soil blocks up the advantages of ability is strong, and mechanical strength is big, cleaning maintenance facilitates.
When this complexes is used, technological process is simple, easy to operate, is filtered using tube type filter membrance and filter press side
Formula had both reclaimed the copper in waste liquid, while nitric acid is regenerated, reduced the processing cost of waste liquid, while the copper nitrate after regeneration
Content is low, if acidity deficiency adjusts its acidity by adding nitric acid and additive, may return to strip line and is continuing with, reach substantially
To zero-emission, the purpose that environmental protection and economy is recycled is realized.
