APPARATUS OF REMOVING SALTS IN SOIL AND METHOD OF MANUFACTURING FLUID FERTILIZER USING THE APPARATUS

摘要

PURPOSE: A manufacturing method of liquid fertilizer using a soil salt removing apparatus is provided to manufacture the liquid fertilizer of which the pH is neutral by collecting anions and cations through flowing a basic or acidic solution to an ion exchange resin in which electrokinetic remediation has been completed. CONSTITUTION: A manufacturing method of liquid fertilizer using a soil salt removing apparatus comprises the following steps: Electrokinetic remediation comprises a cation electrode(10), an anion electrode(20), an anion exchange resin(12a) connected to the cationic electrode and a cationic exchange resin(22a) connected to the anionic electrode. a step of flowing a basic solution to the anion exchange resin in which the electrokinetic remediation has been completed, and an acidic solution to the cationic exchange resin; a step of collecting a solution containing anions recovered from the anionic exchange resin and cations recovered from the cationic exchange resin; a step of mixing the solution containing anions and the solution containing cations to make pH neutral; and a step of producing a liquid fertilizer using the mixed solution.
