Zusammenfassung:The invention discloses a method and a device for continuously treating high-salt desulfurization wastewater. The method comprises the following steps: S100, continuously conveying desulfurization wastewater to a vacuum belt filtering device for filtering treatment; s200, continuously feeding the filtered desulfurization wastewater into a chemical reaction tank for softening treatment; s300, continuously feeding the softened desulfurization wastewater into a flocculent precipitation tank for flocculent precipitation treatment; s400, continuously conveying the SS-removed wastewater to an ultrafiltration membrane unit for ultrafiltration treatment; s500, continuously feeding the wastewater subjected to ultrafiltration treatment into an electrodialysis unit for desalination treatment to obtain a high-concentration salt solution and a low-concentration salt solution; s600, feeding the low-concentration salt solution into a reverse osmosis unit for desalination treatment to obtain reverse osmosis concentrated wate
