Integrated brackish water desalination device, control method, medium, equipment and terminal

The invention belongs to the technical field of brackish water treatment, and discloses an integrated brackish water desalination device, a control method, a medium, equipment and a terminal, and the integrated brackish water desalination device comprises a pretreatment unit, a replacement electrodialysis unit, a bipolar membrane electrodialysis unit and a chelating resin tank. The replacement electrodialysis unit effectively avoids precipitation of a large amount of calcium and magnesium ions in the concentration chamber; the bipolar membrane electrodialysis unit can be used for producing acid and alkali, and the produced acid is used for adjusting the pH value of a polar solution and preventing a polar chamber from scaling; the acid, alkali and saline water alternate renewable resin, hard-removed saline water provided by the chelating resin tank is supplied to the bipolar membrane electrodialysis unit to ensure that the bipolar membrane electrodialysis unit does not scale, and an alkali chamber of the bipol
