Description
Technical field
The utility model belongs to metal plating waste water processing technology field, and in particular at electroplating wastewater reverse osmosis concentrated liquid
The special purpose device of science and engineering skill, makes the nickel qualified discharge in electroplating wastewater.
Background technology
In plating production process, in order to dirt (oil, the rust, iron scale etc.) thorough cleaning before plating plating piece surface is done
Only, need to use a large amount of rinse waters, meanwhile, plating after terminating also needs that plating piece is cleaned multiple times with water.Therefore, in plating production process
Substantial amounts of electroplating wastewater can be produced, often containing heavy metals such as copper, nickel, chromium, zinc in the waste water, and cyanide etc..These pollutions
Thing typically has carcinogenic, teratogenesis and mutagenic property, very big to harm, and the dispersion face of Electroplate Factory is wider, with it
He compares in industry, although wastewater flow rate is relatively fewer, but contamination area is relatively large, and caused pollution is extremely serious.
Therefore, Electroplating Wastewater Treatment work is carried out, hazards of pollutants, the emphasis that always industrial quarters is paid close attention to environmental administration is reduced.
Existing electroplating wastewater generally by " pretreatment+oxidation broken cyanide+neutralization reaction+chemical precipitation+NF+RO " work
Skill is processed, and substantial amounts of reverse osmosis concentrated liquid is produced after the PROCESS FOR TREATMENT, and in the concentrate, nickel content is typically much deeper than
0.1mg/L, it is impossible to reach environmental protection standard.
Utility model content
The purpose of this utility model is to be unable to reach environmental protection for heavy metal nickel in above electroplating wastewater reverse osmosis concentrated liquid
A difficult problem for standard, there is provided a kind of special purpose device of electroplating wastewater reverse osmosis concentration liquor treating process, first by the side of UF membrane
Larger molecular organicses in electroplating wastewater reverse osmosis concentrated liquid are carried out retention separation by formula, reduce COD and complex state in waste water
Nickel, then the complex state nickel that film is produced in water carried out aoxidizing contact break and closing become free state, is then removed by ion exchange resin
The nickel of free state, makes water outlet nickel up to standard.
Technical scheme
In order to realize above-mentioned technical purpose, the electroplating wastewater reverse osmosis concentration liquor treating process of the utility model design it is special
With device, it is characterised in that：It mainly includes film separation unit, oxidation reactor, resin container；
Raw water box is connected with film separation unit, on connecting line be equipped with intake pump, the product water output end of film separation unit with
Oxidation reactor connects, and concentrate output end is connected with regulating reservoir, the output end connection resin container of oxidation reactor, regenerates liquid case
It is connected with resin container, dosing pump is housed on connecting line；Water tank, regenerative wastewater and wash-out are produced in the clear liquid output end connection of resin container
Liquid output end connects regulating reservoir.
Further, the film separation unit is provided with filter, circulating pump and multigroup membrane module.
Further, dosing pump and mixer are provided with the oxidation reactor.
Beneficial effect
The special purpose device of the electroplating wastewater reverse osmosis concentration liquor treating process of the utility model design, initially with UF membrane
Method carries out retention separation to waste water, reduces COD and complex state nickel, then the product water after UF membrane is carried out using advanced oxidation processes
Oxidation contact break is closed, and the nickel for making complex state is become free state nickel, finally free state nickel is removed using ion exchange resin, made
Obtain final outflow water nickel and reach discharge standard.
Description of the drawings
Accompanying drawing 1 is the process chart of the utility model embodiment.
Accompanying drawing 2 is special purpose device annexation schematic diagram in the utility model embodiment.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is elaborated.
Embodiment
As shown in Figure 2, the special purpose device of electroplating wastewater reverse osmosis concentration liquor treating process, it mainly includes UF membrane list
Unit 3, oxidation reactor 5, resin container 6；
Raw water box 1 is connected with film separation unit 3, and intake pump 2 is housed on connecting line；The product water output of film separation unit 3
End is connected with oxidation reactor 5, and concentrate output end is connected with regulating reservoir 10；The output end connection resin container of oxidation reactor 5
6；Regeneration liquid case 9 is connected with resin container 6, and dosing pump 8 is housed on connecting line；Water tank is produced in the clear liquid output end connection of resin container 6
7, regenerative wastewater is connected regulating reservoir 10 with eluent output end.
The film separation unit 1 is provided with filter, circulating pump and multigroup membrane module 4.
Dosing pump and mixer are provided with the oxidation reactor 5.
As shown in Figure 1, the technique that electroplating wastewater reverse osmosis concentrated liquid process is carried out using said apparatus, it includes following
Several steps：
The first step：Pending electroplating wastewater reverse osmosis concentrated liquid contain 1～20mg/L of heavy metal nickel, COD 100～
Between 500mg/L；First the waste water is sent into into film separation system, it is under conditions of operating pressure is 10～40bar, plating is useless
Macromolecular substances in water carry out retention and separate, and reduce the COD of waste water, while removing complex state nickel, make product water nickel content
It is reduced to 0.5mg/L or so；Wherein, the concentrate that the process is produced can return to the regulating reservoir of plant area and be circulated process；
Second step, sends the product water in the first step into advanced oxidation processing system, adjusts the pH of waste water between 2～9, so
After add oxidant, oxidation reaction is carried out in the presence of stirring, the complex state macromolecular substances in waste water are carried out into contact break conjunction,
So that the nickel of complex state changes into free state nickel, water outlet after being aoxidized；
3rd step, by second step oxidation water outlet send into ion exchange system, control waste water flow velocity 20～40m/h it
Between, by the suction-operated of chelating resin, the nickel ion of free state in waste water is adsorbed, so as to remove waste water in nickel.
Wherein, resin need to add regenerated liquid to be regenerated using after saturation, and the regenerative wastewater after regeneration can return to plant area with eluent
Regulating reservoir.
The utility model is using UF membrane, advanced oxidation, the combined treatment process of ion exchange to electroplating wastewater counter-infiltration
Concentrate is processed, and final outflow water nickel meets《Plating pollutant emission standard》GB21900-2008（Table 3）, solve at present
In electroplating wastewater reverse osmosis concentrated liquid nickel cannot high standard discharge a difficult problem, with wide market prospects.
