System.
Background technique
Wastewater flow rate caused by heavy metal-containing waste water, especially PCB industry, electroplating industry is quite big, main succession
Based on COD and heavy metal.Heavy metal chemical coagulation-sedimentation method is generallyd use in the past, forms metal ion in waste water with alkaline agent
It after hydroxide wadding body, then is removed in a manner of precipitation and separation, 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.
At present the treatment process technology of relatively conventional high concentration heavy metal-containing waste water have chemical reduction method, electrolysis method, from
Sub- exchange process and membrane separation method.

It is reacted with medicament and generates synthetic progress precipitation and separation removal, 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 method: the method for electrolysis is to be moved by electric field, charge potential to the metal ion in heavy metal-containing waste water
Move the processing technique of attachment.This processing technique is generally only applicable to that water is less, without the highly concentrated of 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
Several hundred 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 biggish increase, be 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.Metal ion in waste water is by resin adsorption, and resin saturation failure after a period of time, needs to expend a large amount of acid or alkali carries out
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

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, will lead to 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, will affect
Plating quality.
