Abstract
The restoration method of cation exchange resin is characterized by that said method includes the following steps: flushing the resin to be restored, stirring and vibrating, soaking with antitoxic, secondary flushing, injecting regeneration agent into ion exchange unit, soaking, front-flushing and back-flushing. The flushing before restoration can enlarge back-flushing space to increase back-flushing intensity so as to can wash suspension pollutant off resin, and the stirring and vibration by using compressed air can make resin produce mutual friction in its interior so as to wash organic matter off the resin, and the use of antitoxic can remove high-valence inorganic ion and oxide and general organic matter, so that these can make the resin restore to possess normal exchange capacity.
Description
The invention belongs to the process field of water, particularly a kind of method for resuscitation that is used for the cationic ion-exchange resin of water treatment.
Cationic ion-exchange resin is usually used in water correction or desalination is handled.In use, resin is subjected to high price inorganic ions and oxide in the water body, or the organic matter that is had in the exchanged water, or suspension in the water, or the pollution of coal tar wet goods material makes cationic ion-exchange resin be poisoned or destroy, cause the intensity of resin to reduce, lose exchange capacity.Be subjected to high price inorganic ions and oxide in the water body for resin, or the organic matter that is had in the exchanged water, or the pollution of suspension in the water, usually adopt the processing of recovering of hydrochloric acid or compressed air or supersonic wave cleaning machine, but to being subjected to the cationic ion-exchange resin that above-mentioned pollution and coal tar wet goods material pollute simultaneously, can not be with the processing of recovering of these method.
The purpose of this invention is to provide a kind of method for recovering cation-exchange resin, it can make the resin cation that is polluted by suspension, organic matter (comprising coal tar) in high price inorganic ions, the water simultaneously recover normal function of exchange, and uses characteristic of simple in addition.
The objective of the invention is to realize by the following method:
With the resin preceding flushing of recovering, resin volume during flushing: backwash spatial volume=1: 1～1.5 make general pollutant separate discharge with resin particle.With compressed air resin is stirred, shakes, make the mutual friction of interlaminar resin phase, its intergranular separated from contaminants is discharged.
Soak with antidote, make the greasy dirt demulsification, be not attached to resin surface, and remove the high price inorganic ions.Soaking temperature better is 30～90 ℃, preferably 45～75 ℃, is more preferably 50～70 ℃; Soak time better is 20～60 hours, preferably 30～50 hours, is more preferably 35～48 hours.In the immersion process, every 30 minutes, stir, shake once, the time of stirring, shaking is 5～10 minutes.
Antidote can be ion exchange resin antidote for hard-water softener, resin cation antidote, hydrochloric acid.Its concentration is preferably 5～30%, is preferably 8～25%, and more preferably 15%.
It is limpid and for neutral that the flushing of resin after the detoxifcation, its flushing should reach water outlet, soaks positive and negative again washing with injecting regenerative agent.The injection rate of regenerative agent is 2 times of positive usual amounts, soaks 20 hours.
Regenerative agent can be salt or hydrochloric acid or sulfuric acid according to the cation type difference.
The present invention increases backwash intensity because the preceding flushing of recovering increases the backwash space, can wash the suspended contaminant in the resin off; Stir, shake with compressed air, make the mutual friction of interlaminar resin phase, can wash the organic matter in the resin off; Can remove high price inorganic ions and oxide and organic matter in the resin with antidote.Therefore, the present invention can make and be subjected to the resin recovery that suspension, coal tar wet goods material pollute in high price inorganic ions, organic matter, the water simultaneously, and the resin cation after the recovery can recover normal exchange capacity.
