Problems solved by technology

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 chloride ion content in the discharged wastewater is too high, which is not conducive to environmental protection.
In addition, Chinese invention patent application No. 01107319.5 discloses a kind of sodium, ammonia ion resin regenerant, and ammonium chloride content is too high in this regenerant, makes the furnace water alkalinity of boiler on the low side, therefore, there is a problem in the above-mentioned existing regenerant defect

Abstract

A composite regenerant of resin used in treating water contains sodium sulfate (3.5-6 wt portions), sodium chloride (3-6), ammonium chloride (0-0.9), complexing agent (0-0.08) and surfactant (0-0.08). Its advantages are less consumption (decreased by 10%), high regeneration effect and the quantity of soft water to be treated, low Cl content in discharged water, and proper basicity of water in boiler.

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. In addition, Chinese invention patent application No. 01107319.5 discloses a kind of sodium, ...
