PURPOSE: An induction solute collecting method of a forward osmosis process is provided to minimize energy consumption by cooling a part of a solid salt aqueous solution and recycling the cooled product for washing filler. CONSTITUTION: An induction solute collecting method of a forward osmosis process includes the following steps: mixed gas containing ammonia gas, carbon dioxide gas, and vapor is cooled to generate a sublimation reactor to generate solid salt and a solid salt aqueous solution(S10); the solid salt is collected(S20); the solid salt aqueous solution is in contact with the mixed gas(S30); non-reacted ammonia gas is contacted with water to generate ammonia water(S40); and the ammonia water absorbs non-reacted carbon dioxide gas to generate absorption liquid(S50).
