C. the bittern after step b process is filtered by the strainer that built-in filtering material is gac, remove free chlorine, phenol, sulphur, colloidal silicon and other organic pollutant in bittern by carbide, heavy metal substance;
D. the strainer that the bittern after step c process by built-in filtering material is is filtered, remove the Ca in bittern by cation exchanger
2+, Mg
2+deng metal ion;
E. the bittern after steps d process is filtered by the strainer that built-in filtering material is macromolecular material, particulate matter in further removal bittern and impurity, filtering accuracy is 0.1-1 μ, and the bittern after being disposed is work in-process liquid edible salt;
F. the work in-process liquid edible salt will generated through step e process, is placed in an encloses container and heats, and Heating temperature is 35 DEG C-40 DEG C;
G. the work in-process liquid edible salt generated through step f process pressurizeed by pump, being delivered to built-in filtering material is that the strainer of nanofiltration membrane filters, and removes natural organic matter and synthesis of organic substance and a polyvalent salt by nanofiltration membrane;
H. the work in-process liquid edible salt after step g process is undertaken by anion exchanger filtering the Cl removed in work in-process liquid edible salt
-1, SO
4 -or other negatively charged ion, last produce liquid edible salt.
Preferably, the macromolecular material in step b and step e is polysulfones.
Preferably, the strainer related in step a to step h is all pressure resistant vessel, and described bittern, work in-process bittern, liquid edible salt all complete the conveying between each strainer by closed conduit.
Through above-mentioned steps, producing the liquid edible salt drawn is NaCl solution, can reach and meet food hygienic standard and requirement.
And above-mentioned technique is when preparing edible liquid edible salt, because liquid edible salt is direct-edible, without the need to being made crystal salt by evaporation, and then avoid a large amount of energy consumptions, and proposed by the invention a kind of based on the technique of making from brine for liquid edible salt, another development approach is also provided for the bittern being distributed widely in earth's surface or underground.
