Zusammenfassung:	The present invention relates to a sea water desalination system using pressure-retarded osmosis. In detail, according to an embodiment of the present invention, provided is a sea water desalination system using pressure-retarded osmosis which includes: a first and a second pressure exchange apparatus for increasing a pressure of sea water supplied; SWRO equipment for producing generated water by filtering salt from the sea water, of which the pressure is increased, through a reverse osmotic membrane and providing the concentrated salt water to the second pressure exchange apparatus; first PRO equipment for receiving the concentrated salt water discharged from the second pressure exchange apparatus as PRO salt water and PRO source water from the outside to perform a pressure-retarded osmosis process; and second PRO equipment for receiving the PRO salt water discharged from the first PRO equipment to perform a pressure-retarded osmosis process. 본 발명은 압력지연삼투 기술을 이용한 해수담수화 시스템에 관한 것이다. 구체적으로, 본 발명의 일 실시예에 따르면, 해수를 공급받아서 압력을 높이는 제 1 압력교환장치 및 제 2 압력교환장치, 압력이 높아진 해수를 공급받아서 역삼투막을 통해 염분이 여과된 생성수를 생산하고, 농축 염수는 상기 제 2 압력교환장치로 전달하는 SWRO 설비, 상기 제 2 압력교환장치에서 배출되는 상기 농축 염수를 PRO 염수로서 공급받고, 외부로부터 PRO 원수를 공급받아서 압력 지연 삼투 공정이 수행되는 제 1 PRO 설비, 및 상기 제 1 PRO 설비에서 배출되는 PRO 염수를 공급받아서 압력 지연 삼투 공정이 수행되는 제 2 PRO 설비를 포함하는 압력지연삼투 기술을 이용한 해수담수화 시스템이 제공될 수 있다.
