Abstract
The present invention provides a kind of highly efficient regeneration method of hybrid resin, belongs to resource recycling field, includes the following steps, used hybrid resin is put into certain proportion acid or lye and is impregnated；Boiling water is just rinsing hybrid resin；It then proceedes to boiling water to backwash hybrid resin, until hybrid resin is layered；Backwash water flow is gradually reduced, after yin and yang resin layering, stops rinsing；Yin and yang resin is exported respectively, and separating treatment then is carried out to yin and yang resin；Then spare to yin and yang resin alkali or acid solution regeneration treatment.Before hybrid resin separation, by the lye for injecting certain proportion concentration into hybrid resin（Acid solution）, it is hybrid resin middle-jiao yang, function of the spleen and stomach（It is cloudy）Resin is entirely ineffective, then by normal resin backwash operation, uniformly reduces backwash water flow.
Description
Technical field
The present invention relates to resources to reuse field, more particularly to a kind of highly efficient regeneration method of hybrid resin.
Background technology
Because hybrid resin is that yin and yang resin adulterates according to a certain percentage, therefore its water treatment industry is very capable, and its
After failure, to be restored by way of acid-alkali regeneration, it is necessary to carry out the separation of yin and yang resin in advance, then positive resin is used
Acid regeneration, negative resin are regenerated with alkali, but the degree of final regeneration effect.
But the regeneration method efficiency of existing hybrid resin is relatively more beneath, so that the resin after regeneration adulterated
Impurity is more etc., does not meet baseline scale.Therefore, it is necessary to design a kind of highly efficient regeneration side of the less hybrid resin of impurity
Invention content.
The present invention provides a kind of highly efficient regeneration method of hybrid resin, solves the mixed of the regeneration method of existing hybrid resin
Resin impurity is more, the technical issues of cannot meeting minimum baseline scale.
The present invention solves the above problems by the following technical programs：
A kind of highly efficient regeneration method of hybrid resin, includes the following steps,
Step 1：Used hybrid resin is put into certain proportion acid or lye and is impregnated；
Step 2：Boiling water is just rinsing hybrid resin；
Step 3：It then proceedes to boiling water to backwash hybrid resin, until hybrid resin is layered；
Step 4：Backwash water flow is gradually reduced, after yin and yang resin layering, stops rinsing；
Step 5：Yin and yang resin is exported respectively, and separating treatment then is carried out to yin and yang resin；
Step 6：Then spare to yin and yang resin alkali or acid solution regeneration treatment.
Certain proportion acid or lye are the 5-20% acid solutions either lye of 10-25% in the step 1.
The acid solution is that either the sulfuric acid lye is sodium hydroxide or potassium hydroxide to hydrochloric acid.
The time impregnated in the step 1 is -50 minutes 20 minutes.
The time just rinsed in the step 2 is -20 minutes 5 minutes.
It is to reduce within each 30 seconds a water flow that backwash water flow is reduced in the step 4, reduces water flow interval every time
It is identical.
Advantages of the present invention is with effect：
The present invention is to improve the separating effect of hybrid resin, certain by being injected into hybrid resin before hybrid resin separation
The lye of proportional concentration（Acid solution）, it is hybrid resin middle-jiao yang, function of the spleen and stomach（It is cloudy）Resin is entirely ineffective, is then grasped by normal resin backwash
Make, uniformly reduce backwash water flow, yin and yang resin is because itself proportion deviation is larger, therefore positive resin preferential precipitation is in lower layer, the moon tree
Fat is on upper layer.
Specific implementation mode
The invention will be further described with reference to embodiments.
Embodiment
A kind of highly efficient regeneration method of hybrid resin, includes the following steps, includes the following steps,
Step 1：Used hybrid resin is put into certain proportion acid or lye and is impregnated.Certain proportion acid or alkali
Liquid is the 5-20% acid solutions either lye of 10-25%.Acid solution is that either the sulfuric acid lye is sodium hydroxide or hydrogen-oxygen to hydrochloric acid
Change potassium.The time of immersion is -50 minutes 20 minutes.Because resin belongs to a kind of renewable recycling resource can after failure
It is regenerated in a manner of being exchanged by acid ion alkali ion, makes it restore to original treatment process, therefore thermal power plant is removed producing
When brine, general mode is the afterbody purified treatment of system water to be carried out using resin, and yin and yang resin is according to certain ratio
The hybrid resin of example doping, is most common processing method in water treatment technology system.
Step 2：Hybrid resin is just being rinsed with water, is being to carry out positive flushing first, so that hybrid resin
Start to change.The time just rinsed is -20 minutes 5 minutes, it is positive rinse can other times, but this time is best
, effect is best, the regeneration efficiency highest of realization.
Step 3：It then proceedes to boiling water to backwash hybrid resin, until hybrid resin is layered.Due to carrying out
The flushing on two sides, so that yin and yang resin because itself proportion deviation is larger, so that starting to be layered, but starts
It can't stop rinsing after there is layering, need to carry out reduction flow velocity, in order to avoid influence layering.
Step 4：Backwash water flow is gradually reduced, backwash water flow is reduced using uniform, after yin and yang resin layering, stops
Only rinse.It is to reduce within each 30 seconds a water flow to reduce backwash water flow, and it is identical to reduce water flow interval every time.Uniformly reduce
Backwash water flow, yin and yang resin is because itself proportion deviation is larger, therefore positive resin preferential precipitation, in lower layer, negative resin is on upper layer.
Step 5：Yin and yang resin is exported respectively, and separating treatment then is carried out to yin and yang resin.It is cloudy to export yin and yang resin
Positive resin carries out separating treatment with acid solution or lye, so that obtaining regenerated yin and yang resin.
Step 6：Then spare to yin and yang resin alkali or acid solution regeneration treatment.Treated acid solution is carried out to yin and yang resin
Or lye can be reused again, it is therefore desirable to it is collected, keeps next use, also reach graduation resource,
Reduce cost.
Basic flow is：
Hybrid resin → enter certain proportion acid（Alkali）Liquid immersion → hybrid resin just rinses → and hybrid resin backwash layering → by
Step reduces backwash water flow → yin and yang resin layering → yin and yang resin export → the moon respectively（Sun）Resin alkali（Acid）Liquid regenerates.
To improve the separating effect of hybrid resin, before hybrid resin separation, by injecting certain ratio into hybrid resin
The lye of example concentration（Acid solution）, it is hybrid resin middle-jiao yang, function of the spleen and stomach（It is cloudy）Resin is entirely ineffective, then by normal resin backwash operation,
Backwash water flow is uniformly reduced, yin and yang resin is because itself proportion deviation is larger, therefore positive resin preferential precipitation, in lower layer, negative resin exists
Upper layer.
The preferred embodiment of the invention is illustrated above, but the present invention is not limited to embodiment,
Those skilled in the art can also be made under the premise of without prejudice to the invention spirit various equivalent modifications or
It replaces, these equivalent modifications or replacement are all contained in scope of the present application.
