Abstract
The utility model discloses a chromic acid recovery integration device, which comprises a waste water collecting tank, a quartz sand filter, an active carbon filter, a cation exchanger, an anion exchanger and a sodium removal device. The waste water collecting tank is in pipeline connection with the quartz sand filter, the active carbon filter, the cation exchanger and the anion exchanger in sequence, the anion exchanger is respectively connected with an alkali regeneration fluid delivery pipeline and the sodium removal device. The chromic acid recovery integration device can process waste water containing hexavalent chromium, can not only recover water resources, but also can recover chromic acid, is small in occupied area, simple to install and low in operating cost, saves manpower, and meets requirements of cleaning production and circular economy.
Description
Technical field
The utility model relates to the chromate waste water processing technology field, is specifically related to a kind of chromic acid and reclaims integration apparatus.
Background technology
Along with global implementation of sustainable development, the recycling industries and clean production technology more and more receives people's concern.Waste water treatment from end treatment to integrated control stage developments such as process for cleanly preparing, material cycle utilization, waste water recyclings.Through with poisonous improvement be nontoxic, harmful be converted into harmless, reclaim the quantity discharged that heavy metal was eliminated and reduced in measures such as noble metal, water cycle use.Handle the domestic method that contains hexavalent chromium wastewater at present both at home and abroad chemical precipitation method, redox facture, solvent extraction and separation method, absorption method, membrane separation technique, ion exchange treatment method and biological treatment are arranged.
The requirement that above treatment process can not satisfy recycling economy, cleaner production and reclaim heavy metal; Wherein some single treatment process can not satisfy the existing emission standard of country; Can not recycle-water resource and chromic acid, must unite use, make integrated engineering exist to take up an area of many and unite use; Complicacy is installed, and running cost is high, noise reaches shortcomings such as complicated operation greatly.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of chromic acid to reclaim integration apparatus.
Its technical solution is:
A kind of chromic acid reclaims integration apparatus; It comprises waste water collection tank, quartz sand filtration device, activated charcoal filter, cation exchanger, anion exchanger and takes off the sodium device; Waste water collection tank is connected with quartz sand filtration device, activated charcoal filter, cation exchanger and anion exchanger pipeline successively, and anion exchanger is respectively with the alkaline regeneration solution transfer line and take off the sodium device and be connected.
The number of above-mentioned anion exchanger is set to 3, and is connected in series each other.
The useful technique effect of the utility model is:
The utility model can be handled chromyl waste water, can not only the recycle-water resource, can also reclaim chromic acid, and equipment take up an area of less, install simple, running cost is low, practice thrift manpower, satisfies the requirement of cleaner production and recycling economy.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Fig. 1 is the structure principle chart of the utility model.
Among the figure: the 1-waste water collection tank; 2-quartz sand filtration device; The 3-activated charcoal filter; The 4-cation exchanger; 5-first anion exchanger; 6-second anion exchanger; 7-trianion interchanger; 8-reuse water collection box; 9-alkaline regeneration solution transfer line; 10-desorption liquid collection box; 11-takes off the sodium device; 12-chromic acid collection box; The 13-buffer tank; 14-precision stainless steel strainer.
Embodiment
In conjunction with accompanying drawing, a kind of chromic acid reclaims integration apparatus, comprises waste water collection tank 1, is equipped with in the waste water collection tank 1 to contain hexavalent chromium wastewater, contains hexavalent chromium wastewater and filters the filtering suspended substance through quartz sand filtration device 2 and charcoal filter 3 successively.Filtrating is delivered in the cation exchanger 4 by topping-up pump and removes Cr
3+, Fe
3+, Cu
2+Deng metallic cation, and then through placed in-line first anion exchanger 5, second anion exchanger 6 and trianion interchanger 7 removal Cr successively
2O
7 2-And CrO
4 2-Deng negatively charged ion.Go out water conductivity and meet design requirement this moment, and effluent quality is better, can be used as water for cleaning and flow in the reuse water collection box 8, and the reuse water in the reuse water collection box 8 can be delivered to through the reuse water transferpump and use water spot.
First anion exchanger 5, second anion exchanger 6 and trianion interchanger 7 are connected with an alkaline regeneration solution transfer line 9 respectively, and through the alkaline regeneration solution wash-out, desorption liquid compiles the back and flows into desorption liquid collection box 10.Desorption liquid in the desorption liquid collection box 10 takes off in the sodium device 11 through the topping-up pump suction, and in taking off sodium device 11, obtains chromic acid with the RH reaction, and chromic acid flows in the chromic acid collection box 12.Chromic acid in the chromic acid collection box 12 can return plating tank again and use after vacuum concentration equipment concentrates.
Further, chromic acid recovery integration apparatus also comprises deacidifying device and regenerating treater.Deacidifying device is used for the acid that the waste water of taking off behind the chromate still contains is further removed.Regenerating treater is mainly used in the saturated positively charged ion of the ion exchange column in the wastewater treatment, anion regeneration, makes it recover adsorption function, and regeneration once needs 2 hours approximately, the regeneration period be regeneration in 48 hours once.
The system that above-mentioned chromic acid reclaims integration apparatus adopts full automatic control, also can adopt control manually.
The part of not addressing in the aforesaid way is taked or is used for reference prior art and can realize.
Need to prove that under the instruction of this specification sheets, any equivalents that those skilled in the art have done, or obvious variant all should be within the protection domains of the utility model.
