摘要： The present invention discloses a method and an apparatus for desalination of high-salt and high-concentration organic wastewater by coupling three membrane separation technologies. Wastewater is subjected to diffusion desalination to obtain diffusion desalination wastewater and diffusion desalination circulating water; the diffusion desalination circulating water is subjected to reverse osmosis to obtain pure water and high-concentration salt water; and the diffusion desalination wastewater is subjected to forward osmosis to obtain forward osmosis wastewater and forward osmosis circulating water, where the forward osmosis wastewater is desalted and concentrated wastewater.
