Abstract: The present invention discloses an SWRO and MCDI coupled seawater desalination device system with energy recovery, including a pre-filtering unit, an SWRO treatment unit, an MCDI treatment unit, and a post-filtering unit. The SWRO treatment unit is coupled with the MCDI treatment unit. Seawater desalination is performed through a coupling complementary water passage and circuit design, while water quality is improved, and the continuity of water output from a water passage of the device is kept. By recovering the pressure potential energy of high-pressure brine in the SWRO treatment unit and electric energy released by desorption in the MCDI treatment unit, energy consumption is reduced.
