Description

[0002] Brine is a kind of water body containing high concentration of salt, widely used in chemical industry, pharmaceutical industry, food processing and other industries. However, brine often contains sulfate ions (SO4 2- ), which can affect product quality or cause equipment corrosion in some processes. Therefore, removing sulfate ions from brine is an important process step.

[0003] Chinese patent CN101367574B discloses a method for removing sulfate ions from brine or industrial brine. In brine or industrial brine with SO4 2- concentration greater than 10 g / L, 0.5‰-8‰ of the total mass of brine or industrial brine is added, stirred to dissolve, and then white mud produced in the ammonia-alkali process is added, with an addition amount of 20%-30% of the total volume of brine or industrial brine. After stirring and filtering, SO4 2- in brine or industrial brine can be removed. This scheme realizes waste treatment with waste, greatly reducing the cost of removing sulfate ions, and can make the removal cost of sulfate ions in each ton of brine less than 5 yuan RMB. The process is simple, easy to operate, green and environmentally friendly, and does not cause secondary pollution to brine or brine itself and the surrounding environment.
