Separating method of electrolyte and non-electrolyte

Abstract

The invention relates to a separation method of an electrolyte and a non-electrolyte. An anionic membrane is in tight contact with a cationic membrane to form a baffle plate with a downward gap opening so that a mixed solution separates out water through the anionic membrane and the cationic membrane, can be dissociated into an ionic compound material and flows out continuously along the gap opening, and thus water in a mixture of inorganic matters and organic matters containing water and dissolved in water and compounds capable of being dissociated into anions and cations in water are separated out through the anionic membrane and the cationic membrane at a contact interface of the anionic membrane and the cationic membrane with low cost. The separation method can be widely applied to sewage treatment, and processes of dewatering, concentrating, deacidifying, dealkalizing, desalinating and brine-desalinating in an industrial production process.

Description

technical field

[0001] The invention relates to a method for separating electrolytes and non-electrolytes, in particular to the combined application of anion and cation membranes, so that compounds (electrolytes) that can be dissociated into anions and cations in water, together with water itself, are separated through the ionic membrane to achieve water retention. And the mutual separation of compounds (electrolytes) that can dissociate into anions and cations in water and compounds that cannot be dissociated into anions and cations (non-electrolytes) in the original mixture. Background technique

[0002] In various domestic sewage, catering industry sewage, and various industrial sewage (paper pulping, petrochemical, biochemical, pesticide, textile, leather, dyestuff, paint, etc.) treatment fields, all involve oil, or other organic matter and water, acid, Separation or dehydration concentration of alkali and salt. Especially, when acid hydrolyzing cellulose, hemicellulose...
