Description
Technical Field

Background
At present, after the ion exchange resin is used for a period of time, the adsorbed impurities are close to a saturated state, regeneration treatment is carried out, and ions and other impurities adsorbed by the resin are eluted and removed by chemical agents so as to restore the original composition and performance.
In practical application, in order to reduce the regeneration cost, the amount of the regenerant is properly controlled to restore the performance of the resin to the most economical and reasonable regeneration level, and the performance recovery degree is usually controlled to be 70-80%. If higher regeneration levels are to be achieved, the amount of regenerant is increased substantially and the availability of regenerant is reduced.
And the regeneration of the resin should select proper regeneration agent and working condition according to the type and the characteristics of the resin and the economical efficiency of operation. The regeneration characteristics of a resin are closely related to its type and structure. The regeneration of strong acid and strong alkali resin is difficult, and the required regeneration dosage is much higher than the theoretical value; while weakly acidic or weakly basic resins are easier to regenerate, and the amount of the used regenerant is only slightly more than the theoretical value.
The chemical reaction in the regeneration of the resin is the reverse reaction of the original exchange adsorption of the resin. According to the chemical reaction equilibrium principle, the concentration of a certain substance in the chemical reaction is increased, and the reaction can be promoted to proceed to the other substance, so that the regeneration reaction can be accelerated by increasing the concentration of the regeneration liquid, and a higher regeneration level can be achieved.
At present, regeneration solution with 2-3 times of resin volume is commonly adopted for domestic resin regeneration, the resin is completely introduced for 60-80min with 2-3 times of resin volume, then the resin is leached for 30min at the same flow rate of pure water, and the flow rate is increased until the pH of effluent is 6-7.
