Abstract
The method for resuscitation of the cation exchange resin of DDA pollutions, it is related to the method for resuscitation and recovery medicament of the cation exchange resin of DDA pollutions, the invention solves existing method for resuscitation to repeatedly by the cationic ion-exchange resin anabiosis of DDA pollutions, the effect is relatively poor, DDA blocks resins exchange duct and by Van der Waals force absorption on resin, occupies the problem of exchanging site.The method for resuscitation for the cation exchange resin that DDA pollutes is implemented by the following steps in the present invention：First, air bump rinse operation；2nd, regenerate.Remove the pollutions of the DDA in positive resin and make its recovery；3rd, rinse.Recovery medicament in the present invention used in the method for resuscitation for the cation exchange resin that DDA pollutes, is made of NaCl, NaOH, surfactant and water.The present invention is suitable for the recovery of positive resin DDA pollutions.
Description
Technical field
The present invention relates to a kind of method for resuscitation, and in particular to be that the cation exchange resin that ion-exchanger uses is subject to
Lauryl amine（DDA）The method for resuscitation of pollution.
Background technology
The widely used ion-exchange salt removing system of power plant water process, i.e. cation exchanger-anion exchanger-mixed
Close ion-exchanger, ion exchange resin（Abbreviation resin）It is the key job medium of the system, it determines desalting system water
Matter and the cycle of operation.When resin is contaminated, it may appear that effluent quality is deteriorated, and operating capacity declines, cycle of operation contracting
The problems such as short.And with the continuous development of ETA operating modes, pollution problems of the ETA+DDA to resin is badly in need of solving.
Pollution mechanisms of the DDA to resin：First, " outpost of the tax office effect " of the resin to organic matter.Phenylethylene resin series are by the inner
Portion's structure it is uneven, when DDA is entered inside resin, be easily stuck in those and be crosslinked close regions, so as to block resin duct
Pollute.Second, ion exchange of the resin to organic matter.Organic matter can be with Ca2+Complex reaction, shape occurs Deng cation
Adsorbed into compounds such as DOM-Ca by ion exchange on positive resin.Third, Van der Waals masterpiece of the resin to organic matter
With.Because most of organic matter is hydrophobic in water, the resin synthesized by aromatic hydrocarbon is also that hydrophobic, strong molecule is inhaled
Gravitation makes them be firmly adsorbed on together, is difficult to desorb with general renovation process.
Its whole operating capacity can not be recovered by common renovation process by the resin of DDA pollutions, it is especially positive
Resin resin industry and traffic after repeatedly being polluted is changed into the 30 ~ 45% of initial industry and traffic.Therefore, it is necessary to develop a kind of processing resin
The method for resuscitation of DDA pollutions.
The content of the invention
It is an object of the invention to provide a kind for the treatment of effect it is good, it is easy to use for DDA pollution resin again
Raw agent, the regenerative agent can reduce power plant condensation crystal's processing cost.
The regenerative agent of the cationic ion-exchange resin anabiosis for being polluted by DDA proposed of the present invention includes weight percent
Than for：10 ~ 15% sodium chloride, 1 ~ 5% sodium hydroxide, 10 ~ 15% TX, remaining component are water.
The present invention through the following steps that realize：First, air bump rinse operation：To contaminated resin in ion-exchanger, profit
The scouring 2h of big yield is carried out with internal scrubbing system, so as to improve the effect of recovery.2nd, cation exchange resin DDA is removed
Pollute and make its recovery：The cumulative volume of regenerative agent is treat recovery positive resin volume 4.5 times, is divided into 3 times to cation exchange tree
Fat carries out elution recovery, and the volume of every batch of regenerative agent is treat recovery cation exchange resin volume 1.5 times, and recovery every time uses
Regenerative agent percentage by weight be 10 ~ 15% NaCl+1 ~ 5% NaOH+10 ~ 15% TX, with counter-current regeneration method regeneration 1 ~
3h, flow velocity are 3 ~ 4m/h.Resuscitation process temperature control between 38 ~ 42 DEG C, the control of recovery time of last time 2 ~ 4h it
Between, and last time is regenerated as static regeneration method.3rd, rinse：After having regenerated every time, cation exchange resin deionized water
10 ~ 15min is rinsed, with deionized water rinsing to PH=7 or so after having regenerated for the last time.So could very effectively it remove
DDA in organic matter.
Beneficial effects of the present invention：
1. the present invention is regenerated using salt and alkali method, compared with conventional method, elution environment ion intensity is larger, and being conducive to macromolecular has
Machine thing comes off, and strong acid group exchange capacity is added after elution；
2. each formulatory agents of the present invention and equipment are simple, cheap, applicability and cost-effective, easy to promote；
3. the present invention with the addition of surfactant in regenerative process, preferably DDA can be eluted；
4. the present invention uses air bump rinse operation before regeneration, contribute to the parsing and migration of organic matter；
5. regenerative agent of the present invention has the characteristics that efficient.The operating capacity of cation exchange resin can be extensive after regeneration
Again to 95%, while without oxidisability medicament is used in regenerative process, which will not damage resin.
