Description
Technical field
The present invention relates to a kind of processing system for removing tin in PCB industrial wastewater, belong to useless in environmental protection
Water treatment field.
Background technology
In recent years, developing rapidly with electronic information industry, printed circuit board (PCB)（PCB）Demand and yield significantly increase
Plus.The printed circuit board (PCB) output value of China has occupied more than the 25% of the global gross output value, the printed circuit board (PCB) manufacture as the first in the world
Base.But, resulting stanniferous waste water pollution problem also becomes increasingly serious, except the valuable high concentration in part is stanniferous useless
Liquid reclaims outer by professional recovery company, and a large amount of waste water containing low concentration tin need to process qualified discharge.Therefore, to printed circuit board work
The stanniferous waste water of industry is effectively treated the challenge for having turned into enterprise.
Because plating wastewater enters water body extensive and serious harm can be produced to ecological environment and the mankind, so
Research to plating wastewater treatment technology becomes more and more important.Reusing sewage and metal are carried out to the stanniferous waste water of printed circuit board (PCB)
Tin is reclaimed, can not only saving water resource, protection water environment, and reclaiming the metallic tin that obtains, can also effectively to solve metals resources short
Scarce problem, reaches the target that economic benefit is taken into account with environmental benefit.
Because plating wastewater produces node many, and composition is more complicated, therefore administers the method master of its waste water at present
There are two major classes, i.e. physical-chemical process and bioanalysis, mainly including coagulating sedimentation, ion exchange, Bubble-floating Method, absorption method, iron carbon
Micro-electrolysis method, catalytic oxidation, biological degradation method and combination treatment method etc..
（1）Coagulation Method.In printed circuit board (PCB) production process, the organic wastewater and heavy metal of some high concentrations can be produced to give up
Water.The waste water complex for this water quality, coagulating can effectively remove colloidal solid in waste water etc., moreover it is possible to
The organic matter being dissolved in water phase forms the precipitation of slightly solubility.Conventional coagulant includes inorganic coagulant and organic coagulants two
Major class, wherein inorganic coagulant are mainly FeCl3、Al2（SO4）3And its polymer.Organic coagulants include cation high molecular
Coagulant, both sexes organic polymer coagulant, anionic high-molecular coagulant adopting and nonionic coagulant.
（2）Ion-exchange is to be chelated with heavy metal ion by the amino isoreactivity group in resin, exchange anti-
Should, so that the method for removing heavy metal ions in wastewater.Conventional ion exchange resin has cationic ion-exchange resin, anion to hand over
Change resin, chelating resin and Humic Acid Resin.
（3）Bubble-floating Method.Bubble-floating Method is to being passed through air in waste water, and to be separated out from water in micro-bubble form as carrying
Body, makes the polluters such as the oil emulsion in waste water, small suspended particulate stick on bubble, and the water surface is floated to bubble,
Form foam-gas and water, particle（Oil）Three-phase mixture, separation impurity, purification waste water are reached by collecting foam or scum silica frost
Purpose.
（4）Absorption method.Absorption method is to utilize porous solid sorbent treatment pollutant, one or more in pollutant
Component is attracted to the surface of solids in the presence of molecular attraction or chemical bond, so as to reach the purpose of separation.Conventional absorption
The active charcoal of agent, humic acid, sepiolite, polysaccharide resins etc..
（5）Fe-C Micro Electrolysis Method.The electrolysis material of rail carbon micro-electrolytic processes typically uses cast-iron scrap and activated carbon or Jiao
, when material is immersed in waste water, there is inside and outside both sides cell reaction in charcoal.The product of electrode reaction production has
Activity very high, can occur redox reaction with various ingredients in waste water, and many difficult for biological degradation and poisonous material are all
Can effectively be degraded；The heavy metal ion that metal can be come after iron with metal activity series in waste water simultaneously is put
Change reaction.Iron-carbon micro-electrolysis are exactly the purpose that removal water pollutant is reached by these effects.
（6）Catalytic oxidation.Catalysis oxidation refers under certain pressure and temperature conditionss, with metal material Pt, Pd, Ni etc.
It is catalyst, with the oxidation reaction that air, oxygen, ozone etc. are carried out for oxidant, including effect of both oxygenation and dehydrogenation.
Using the decomposition of oxidation reinforced dose of catalysis oxidation to accelerate the chemical reaction between Pollutants in Wastewater and oxidant, go in water removal
Pollutant.
（7）Bioanalysis and Combined Treatment method.Biological degradation method, mainly uses the sludge or natural that sewage treatment plant returns
Microorganism is processed PCB waste water.Bioanalysis is not high to the clearance of high concentration PCB waste water, and degraded is not thorough, thus needs
Chemical treatment is set up to make up above-mentioned deficiency, i.e., plating wastewater is administered with the united handling process of biological-chemical.So
It is more and more concerned with other method combined treatment board wastewater using bioanalysis, reported have coagulation-contact oxidation method,
Counter-infiltration-electrodeionization（RO-EDI）Desalination system, Production Wastewater By Combined Acidification And Demulsification-iron-carbon micro-electrolysis-neutralization precipitation-SBR group technologies etc..
Regular maintenance of the conventional physical method as required for filtering, adsorption method of separation is costly, the small and secondary dirt for the treatment of capacity
The problems such as dye.The major defect of bioanalysis is that the complexity of microorganism structure determines microbiological treatment plating wastewater
Mechanism is extremely complex, and process time is long, it is big, unstable etc. to be affected by the external environment.Therefore, it is necessary to break away from existing treatment skill
Art thinking, hews out the new way of removal PCB heavy metals in industrial wastewater, and then develop a kind of PCB of new type
The treatment technology of circuit-board industry heavy metal in waste water.
