With, the sodium ion in the sodium chloride that the chlorination waste liquor of sodium is included replace the calcium that the inactive ion exchange resin is adsorbed from
Son and/or magnesium ion can make the inactive ion exchange resin that can be re-used in hard water purification.
Specific implementation mode
A better embodiment of the invention provides a kind of recoverying and utilizing method of chlorination waste liquor of sodium, for amberlite
Fat carries out regeneration.
Wherein, the water of the calcium ion containing high concentration and/or magnesium ion is known as hard water, and hard water can not be applied to circuit board
Wet process in.Therefore, it is necessary to use ion exchange resin to adsorb calcium ion and/or magnesium ion in hard water, thus by hard water
Purification is soft water, could be used by circuit board wet process.In general, the ion exchange resin, which contains a certain concentration, has activation energy
The sodium ion (hereinafter referred to as activating ion exchanger resin) of power, can in hard water calcium ion and/or magnesium ion exchange.
However, saturation can be reached after ion exchange resin absorption calcium ion and/or magnesium ion, it is made to lose exchange capacity (hereinafter referred to as
For inactive ion exchange resin).Therefore, using the recoverying and utilizing method of the chlorination waste liquor of sodium to inactive ion exchange resin into
After row regeneration, the activating ion exchanger resin that can be re-used in hard water purification can be regained.
In the present embodiment, the recoverying and utilizing method of the chlorination waste liquor of sodium includes the following steps：
Step 1：Remove the suspended impurity and organic matter in the chlorination waste liquor of sodium.
In the present embodiment, the chlorination waste liquor of sodium is successively added in filter device and activated carbon purifier to divide
Suspended impurity and organic matter therein are not removed.Contain activated carbon in the activated carbon purifier, is used to adsorb the chlorine
Change the organic matter in waste liquor of sodium.
In the present embodiment, the mass concentration of sodium chloride in the chlorination waste liquor of sodium after suspended impurity and organic matter is removed
About 3~6%.
Step 2：The chlorination waste liquor of sodium after removal suspended impurity and organic matter is added in inactive ion exchange resin
The sodium ion reacted in the sodium chloride for making the chlorination waste liquor of sodium be included for a period of time replaces the inactive ion exchange resin
The calcium ion and/or magnesium ion adsorbed, to generate calcium chloride and/or magnesium chloride.
Wherein, the inactive ion exchange resin is generally spherical before carrying out water softening, with larger surface area,
Be conducive to improve adsorption capacity.The reaction principle of spherical inactive ion exchange resin and sodium chloride (only shows magnesium as follows
Ion is substituted)：
Wherein, the calcium ion in inactive ion exchange resin absorption hard water and/or magnesium ion typically exhibit after reaching saturation
Yellow, and after calcium ion and/or magnesium ion are fully substituted, inactive ion exchange resin can become white, therefore this implementation
The calcium ion for judging to be carried on the inactive ion exchange resin can be observed by the naked eye in mode and/or whether magnesium ion is complete
Full substitution, so that it is determined that the reaction time.
Step 3：The inactive ion exchange resin after reaction is rinsed to remove calcium chloride and/or magnesium chloride, to obtain
The activating ion exchanger resin utilized must be repeated.
In the present embodiment, the inactive ion exchange resin, the body needed for the pure water are rinsed using pure water
