摘要
The present invention relates to a forward osmosis inducing solution recovery method in a forward osmosis type seawater-desalination process. The recovery method according to an embodiment of the present invention comprises a preparation step of preparing an osmosis reactor including a forward osmosis inducing solution container, a seawater container, and an osmosis membrane positioned between the forward osmosis inducing solution container and the seawater container, supplying a forward osmosis inducing solution including ammonium bicarbonate to the forward osmosis inducing solution container, and supplying seawater to the seawater container; a forward osmosis reaction step of passing water molecules of seawater through the osmosis membrane to form a mixed solution having a diluted forward osmosis inducing solution; a desalination step of heating the mixed solution having completed the forward osmosis reaction step, distilling to separate fresh water, and discharging the fresh water; and a recovery step of dissolving ammonia gas and carbon dioxide gas generated in the desalination step in water to recover the forward osmosis inducing solution. In the recovery step, the volume ratio of the ammonia gas and the carbon dioxide gas is controlled to be constant so that the ammonia gas is first dissolved in water to form aqueous ammonia, and the aqueous ammonia contacts with carbon dioxide gas to improve the solubility of the carbon dioxide gas.;COPYRIGHT KIPO 2014
