The utility model discloses a small reverse osmosis sea water desalinization system adopting a self-pressurization energy recycling high-pressure pump. The small reverse osmosis sea water desalinization system adopting the self-pressurization energy recycling high-pressure pump comprises the following technological process: pumping sea water by virtue of a raw water pump, carrying out pre-treatment, causing the pretreated sea water to directly enter yjr self-pressurization energy recycling high-pressure pump to be pressurized, and causing high pressure raw water meeting reverse osmosis pressure requirement to enter a reverse osmosis membrane pressure container, wherein fresh water after desalinization is carried out by virtue of a reverse osmosis membrane is producing water of the small reverse osmosis sea water desalinization system, strong brine discharged from the reverse osmosis membrane pressure container enters the high pressure concentrated water hole of the self-pressurization energy recycling high-pressure pump to be subjected to residual pressure recycling, and low pressure strong brine after residual pressure recycling is discharged from the low pressure concentrated water outlet of the energy recycling high-pressure pump. Effective energy conversion efficiency of residual pressure utilization of the small reverse osmosis sea water desalinization system adopting the self-pressurization energy recycling high-pressure pump can be more than 90%.
