Description

Background
The ion exchange resin is widely applied to water treatment processes in the industries of electric power, food, chemical industry and the like, and plays an irreplaceable role. In the using process, due to various reasons, cation exchange resin is polluted by iron, aluminum, oil and the like, anions are polluted by organic matters, so that the ion exchange system has the series problems of water quality deterioration, low periodic water production amount, frequent resin regeneration and the like, and for the resin pollution, the resin performance cannot be effectively improved by the traditional backwashing and acid-base regeneration process.
In order to solve the series of problems caused by the pollution of the resin, the pretreatment process is improved to reduce the pollutant components in the inlet water of the ion exchanger, and the resin needs to be recovered, and the common resin recovery method comprises the following steps: the recovery method comprises an alkaline sodium chloride recovery method, an oxidant recovery method, a surfactant recovery method, an organic solvent method and the like, wherein the temperature of the recovery liquid is properly increased according to the composition of the recovery liquid and the temperature tolerance of resin and equipment during recovery, so that a better recovery effect is achieved.
At present, many water treatment workshops are not provided with hot water tanks, the temperature which can not meet the requirements of a recovery process can only be achieved by normal-temperature recovery, but the recovery effect is not ideal, particularly, the effect is poor when the water temperature is low in winter, a recovery liquid usually consists of a plurality of chemical agents, and both liquid and solid exist, the water treatment workshops are usually provided with resin recovery tanks, if recovery is performed in the resin recovery tanks, acid or alkali for regeneration can be directly added into the recovery tanks by utilizing the existing acid and alkali conveying systems of the workshops, but other agents cannot be directly added due to the fact that special dispensing equipment and conveying pipelines are not provided, if other agents are added by utilizing the existing acid and alkali metering tanks, the metering tanks and the pipelines need to be thoroughly cleaned after use, otherwise, the normal operation resin regeneration effect can be directly influenced, certain risks exist, and therefore, during recovery, the method comprises the following steps that an operator usually uses a resin recovery tank as a container for preparing recovery liquid, then the recovery liquid is input into an ion exchanger where the resin is located to recover the resin, if acid or alkali for regeneration is one of the components of the recovery liquid, the acid or alkali and desalted water are firstly conveyed into the recovery tank, and then the recovery liquid is poured into other required agents from a manhole door of the recovery tank to prepare the other agents; for solid medicament, if the adding amount is larger, in order to avoid hardening during pouring, the solid medicament is usually prepared into high-concentration solution by water, and then the solution is poured into the resuscitation tank from a manhole door of the resuscitation tank. In addition, for the existing resin ion exchanger or resuscitation tank, resuscitation liquid cannot be recycled after passing through resin, a large amount of medicament is needed by long-time dynamic resuscitation, and in order to save medicament consumption, operating personnel usually adopt a repeated soaking resuscitation process, namely, after the resuscitation liquid prepared in the resuscitation tank is conveyed to the ion exchanger where the resin is located, standing and soaking are carried out for a long time, then the resuscitation liquid is emptied, then the resuscitation liquid is prepared again for soaking, and the resuscitation effect is improved through continuous repeated resuscitation.
In a word, the existing water treatment plant for ion exchange resin resuscitation generally has the problems that the components of the resuscitation solution are not uniformly mixed, the resuscitation solution temperature cannot meet the process requirements, the resuscitation medicament consumption is high, the resuscitation time is long, the operation is complicated, the labor capacity of personnel is large and the like, and the problems not only cause the poor resuscitation effect of the resin and cannot achieve the expected effect, but also are uneconomical.
