Abstract

A regenerating agent of sodium and ammonium ion resin is prepared from sodium chloride (4-6 wt.portions), sodium sulfate (1-3), ammonium chloride (1-4), complexing agent (0-0.2) and surfactant (0-0.2) and can be used for water processing to obtain soft water. Its advantages include less consumption of edible salt saved by 5-10%, low cost reduced by 10%, high quality of soft water, long service life of resin and low chlorine content in discharged water (reduced by 25%).

Description

technical field [0001] The invention relates to a regeneration agent, in particular to a regeneration agent for strongly acidic styrene series cation exchange resin and sulfonated coal, which is specially used for soft water treatment. Background technique [0002] Chinese invention patent application No. 93120933.1 discloses a composite regeneration agent for hard water softeners. The main component of the regeneration agent is sodium chloride. The sodium ions in the sodium chloride are exchanged with the calcium and magnesium ions adsorbed on the resin in the softener. , to regenerate the ion exchange resin. But above-mentioned existing regeneration agent salt consumption is bigger, and use cost is higher. At the same time, during the resin regeneration process, the chlorine ion content in the discharged wastewater is too high, which is not conducive to environmental protection. Therefore, the above-mentioned existing regenerants have drawbacks. Contents of the inventi...
