    • PURPOSE: An induced solution for forward osmosis, a forward osmosis-based water treating apparatus using the same, and a forward osmosis-based water treating method are provided to improve water treating effect. CONSTITUTION: An induced solute for forward osmosis includes copolymer containing a first structural unit and a second structural unit. The first structural unit is composed by graft-polymerizing a temperature sensitive oligomer side chain containing a side chain forming structural unit with a temperature sensitive moiety. The second structural unit includes a hydrophilic functional group. The temperature sensitive moiety is a monovalent substituent represented by chemical formula 1, a monovalent substituent represented by chemical formula 2, and divalent substituent represented by chemical formula 3. In chemical formulas 1 to 3, R1 and R2 are respectively hydrogen atoms, linear or branched C3-C5 alkyl groups; either R1 or R2 is not a hydrogen atom; R3 is C3-C5 alkylene group; and R4 is a linear or branched C3-C5 alkyl group.
    • 目的:提供正向渗透的诱导溶液,使用其的正向渗透型水处理装置和正向渗透型水处理方法,以改善水处理效果。 构成:用于正向渗透的诱导溶质包括含有第一结构单元和第二结构单元的共聚物。 第一结构单元由含有侧链形成结构单元的温度敏感性低聚物侧链与温度敏感部分接枝聚合而成。 第二结构单元包括亲水官能团。 温度敏感性部分是由化学式1表示的一价取代基,由化学式2表示的一价取代基和由化学式3表示的二价取代基。在化学式1〜3中,R 1和R 2分别为氢原子,直链或支链 C3-C5烷基; R1或R2不是氢原子; R3是C3-C5亚烷基; 且R 4为直链或支链C 3 -C 5烷基。
