Description
Technical field
The present invention relates to technical field of waste water processing, especially a kind of integrated processing system of heavy metal-containing waste water.
Background technology
Wastewater flow rate is quite big caused by heavy metal-containing waste water, especially PCB industries, electroplating industry, main succession
Based on COD and heavy metal.Past generally use heavy metal chemical coagulation-sedimentation method, makes metal ion in waste water be formed with alkaline agent
After hydroxide flco, then to precipitate separate mode removal, waste water is again into biochemical treatment after heavy-metal ion removal.But this place
Reason method, consumption of chemicals is big, and processing cost is high, and heavy workload, treatment effect is unstable, is unable to qualified discharge.
The treatment process technology of current relatively conventional high concentration heavy metal-containing waste water have chemical reduction method, electrolysis, from
Sub- exchange process and membrane separation method.
Chemical reduction method：It is chemically reacted by putting into relevant medicament in heavy metal-containing waste water, each metal ion
Generation synthetic is reacted with medicament and carries out precipitation separation removal, and this method is uncontrollable etc. by influent concentration and Adding medicine control variation
Factor can not accomplish that stably reaching standard discharges, and treated, and waste water also cannot achieve reuse to procedure for producing.
Electrolysis：The method of electrolysis is moved to the metal ion in heavy metal-containing waste water by electric field, charge potential
Move the treatment technology of attachment.This treatment technology is generally only applicable to that water is less, highly concentrated without other foreign metal ions
Waste water is spent, the ion in waste water is finally recycled with sheet metal.But to general low concentration, concentration only have tens or
Hundreds of ppm, water is big, and low concentration and concentration change greatly heavy metal-containing waste water, and the method for electrolysis is difficult to realize in waste water
Metal ion carries out effective mobility.Moreover, waste water its salinity after electrolysis has larger increase, it is difficult to accomplish stable emissions and
Reuse.
Ion-exchange：Ion-exchange inhales the metal ion in waste water generally by ion exchange resin
It is attached.By resin adsorption, resin saturation failure after a period of time needs to expend a large amount of acid or alkali carries out metal ion in waste water
Elution and regeneration.Regenerative process needs a large amount of tap water to be eluted and cleaned, this large amount of ejected wash water also contains residue gold
Belong to ion, it is also desirable to could be discharged after being handled.Ion exchange resin will fail for a period of time after Reusability,
Whole all replacements are needed after failure, cause high processing cost.
And film process is used, waste water can be handled well, and film produces water also can stably reaching standard discharge.But the concentration of film has centainly
The limit, i.e., when Waste water concentrating to a certain extent after, with the raising of concentration, conductivity rises, concentration of metal ions rises,

System, has damage to film, influences membrane lifetime；And some conductivity of waste water are excessively high, are also not suitable for into membranous system, can cause membranous system without
Produce water.
Processing is seen through using counter, to low concentration, in the waste water of≤500mg/L, processing water outlet can continue metal ion content
It is used in plating piece rinsing, does not influence wash effect, but for the higher dope of metal ion 500mg/L concentrations above containing a huge sum of money
Belong to waste water, water is produced after processing and is unable to stably reaching standard, is more than discharge standard value range.Coating bath cannot be directly returned simultaneously, can be influenced
Plating quality.
