Zusammenfassung:Disclosed, is a method for removing inorganic salt in mannose mother solution by using ion resin, including the following steps: enabling a mannose mother solution to flow through anion and cation resin tanks at a flow speed, of 350 m3/h-400 mé/h, and performing combined cyclic regeneration on anion and cation resins by a carbon dioxide dissolving solution; pre-treating raw water by a first cation resin tank; stopping water feeding, and performing combined, cyclic regeneration. on anion and cation resins; performing deep regeneration on the anion resin, mixing water, and enabling the mixed, water' to enter the water storage tank; and enabling' water in the water storage tank to flow into a clean water tank. The anion. resin containing bicarbonate is combined with secondary cyclic regeneration of carbon dioxide and deep regeneration of sodium bicarbonate for desalting, the efficiency reaches 90% or above, cost is saved, and environmental pollution is reduced.
