Description
Technical field
The present invention relates to a kind of remove the processing method of stannum in PCB industrial wastewater, belong in environmental conservation is useless
Water treatment field.
Background technology
In recent years, along with developing rapidly of electronic information industry, demand and the yield of printed circuit board (PCB) (PCB) significantly increase
Add.The printed circuit board (PCB) output value of China has occupied more than the 25% of the whole world gross output value, becomes world-class printed circuit board (PCB) manufacture
Base.But, consequent stanniferous waste water pollution problem also becomes day by day serious, except the valuable high concentration of part is stanniferous useless
Liquid is reclaimed outside company's recovery by specialty, and a large amount of waste water containing low concentration stannum need to process qualified discharge.Therefore, to printed circuit board work
The stanniferous waste water of industry is effectively treated the challenge becoming enterprise.
Ecological environment and the mankind can be produced extensive and serious harm owing to plating wastewater enters water body, so
Research to plating wastewater treatment technology becomes more and more important.Waste water stanniferous to printed circuit board (PCB) carries out reusing sewage and metal
Stannum reclaims, can not only saving water resource, protection water environment, and the metallic tin reclaiming acquisition can also effectively to solve metals resources short
The problem lacked, reaches the target that economic benefit is taken into account with environmental benefit.
Owing to plating wastewater generation node is many, and composition is more complicated, administers the method master of its waste water the most at present
There are two big classes, i.e. physical-chemical process and bioanalysis, mainly include the exchange of coagulating sedimentation, ion, air supporting method, absorption method, ferrum carbon
Micro-electrolysis method, catalytic oxidation, biological degradation method and combination treatment method etc..
(1) Coagulation Method.In printed circuit board (PCB) production process, organic wastewater and the heavy metal that can produce some high concentrations are given up
Water.For the waste water that this water quality is complex, coagulating can effectively remove the colloidal solid etc. in waste water, moreover it is possible to
The Organic substance being dissolved in aqueous phase forms the precipitation of slightly solubility.Conventional coagulant includes inorganic coagulant and organic coagulants two
Big class, wherein inorganic coagulant is mainly FeCl3、Al2(SO4)3And polymer.Organic coagulants includes cation high molecular
Coagulant, both sexes organic polymer coagulant, anionic high-molecular coagulant adopting and nonionic coagulant.
(2) ion exchange is to carry out chelating, exchanging instead by the amino isoreactivity group in resin and heavy metal ion
Should, thus the method removing heavy metal ions in wastewater.Conventional ion exchange resin has cation exchange resin, anion to hand over
Change resin, chelating resin and Humic Acid Resin.
(3) air supporting method.Air supporting method is to be passed through air in waste water, and separates out from water with micro-bubble form and become load
Body, makes the polluters such as the oil emulsion in waste water, small particle stick on bubble, floats to the water surface with bubble,
Form foam gas and water, granule (oily) three-phase mixture, by collecting foam or scum silica frost to reach to separate impurity, purify waste water
Purpose.
(4) absorption method.Absorption method is to utilize porous solid sorbent treatment pollutant, one or more in pollutant
Component, under the effect of molecular attraction or chemical bond, is attracted to the surface of solids, thus reaches the purpose separated.Conventional absorption
The active charcoal of agent, humic acid, meerschaum, 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 that electrode reaction produces has
The highest activity, it is possible to various ingredients generation redox reaction in waste water, many difficult for biological degradation and poisonous material are all
Can effectively be degraded；Heavy metal ion after metal can come ferrum with metal activity series in waste water simultaneously is put
Change reaction.Iron-carbon micro-electrolysis is through these effects and reaches to remove the purpose of water pollutant.
(6) catalytic oxidation.Catalysis oxidation refers under certain pressure and temperature conditions, with metal material Pt, Pd, Ni etc.
For catalyst, the oxidation reaction carried out for oxidant with air, oxygen, ozone etc., act on including of both oxygenation and dehydrogenation.
Utilize the decomposition of oxidation reinforced dose of catalysis oxidation to accelerate the chemical reaction between Pollutants in Wastewater and oxidant, remove in water
Pollutant.
(7) bioanalysis and Combined Treatment method.Biological degradation method, the mud or natural returned mainly by sewage treatment plant
PCB waste water is processed by microorganism.Bioanalysis is the highest to the clearance of high concentration PCB waste water, and degraded is not thorough, thus needs
Set up chemical treatment to make up above-mentioned deficiency, i.e. process technique with biological-chemical in combination and administer plating wastewater.So
Use bioanalysis more and more concerned with additive method combined treatment board wastewater, reported have coagulation-contact oxidation method,
Reverse osmosis-electrodeionization (RO-EDI) desalination system, Production Wastewater By Combined Acidification And Demulsification-iron-carbon micro-electrolysis-neutralization precipitation-SBR group technology etc..
Regular maintenance required for conventional physical method such as filtration, adsorption method of separation is costly, treating capacity is little and secondary is dirty
The problems such as dye.The major defect of bioanalysis is that the complexity of microorganism structure determines microbial treatments plating wastewater
Mechanism is extremely complex, process time length, be affected by the external environment big, unstable etc..Therefore, it is necessary to break away from existing process skill
Art thinking, hews out the new way removing PCB heavy metals in industrial wastewater, and then develops the PCB of a kind of new type
The treatment technology of circuit-board industry heavy metal in waste water.
