Abstract
A flow electrode capacitive deionization system and a method for recovering phosphorus in phosphogypsum leachate and synchronous performing brine desalination belong to the technical field of wastewater treatment and recycling. The flow electrode capacitive deionization system includes a phosphorus recovery electrodeionization module and a desalination electrodeionization module. A first flow electrode solution reservoir, a phosphorus recovery electrodeionization module cathode flow electrode chamber, and a desalination electrodeionization module anode flow electrode chamber are interconnected in a circulation. A second flow electrode solution reservoir, a phosphorus recovery electrodeionization module anode flow electrode chamber, and a desalination electrodeionization module cathode flow electrode chamber are interconnected in a circulation. Two independent flow electrode solution circulation loops are formed. The phosphogypsum leachate enters the phosphorus recovery electrodeionization module and phosphorus is enriched into a flow electrode solution. A phosphorus-rich solution is reacted with a ferrous solution under an oxygen-free condition to generate vivianite [Fe(PO)·8HO].
