After in situ oxidation treatment, the content of organic matter in salt is less, and the removal rate of organic matter is more than 99%, which greatly expands the utilization way of recycled salt.
In situ oxidized by-product salt is pure salt with single component (NaCl, Na2SO4, etc.), which can be reused for production or sold as by-product salt. Na2SO4 can be used for water glass, glass, porcelain glaze, pulp production. NaCl can be used in the electrolytic process of saturated NaCl solution to produce hydrogen, chlorine and caustic soda and other chlor-alkali industries.
