A　sequencing　batch　two　chamber　electrolysis　cell　was　set　up　to　recover　phosphate(P)　from　synthetic　wastewater　containing　KH2PO4　with　different　gradients.In　the　cell,　ferrous　iron　goes　into　the　liquor　from　iron-anode　to　precipitate　soluble　P　and　form　vivianite.The　two-chamber　electrolytic　cell　provides　a　suitable　pH　range　for　the　formation　of　vivianite　without　adding　acid　and　alkali,　which　saves　costs　and　avoids　waste　of　resources.　After　repeated　experiments　with　different　gradients,　the　minimum　phosphorus(P)　removal　efficiency　was　stably　achieved　at　97.17　%.　After　long-term　operation,　the　P　removal　effect　was　not　affected　despite　the　fouling　of　the　proton　exchange　membrane(PEM).　Further　analysis　by　XRD,　FITR　and　SEM　illustrated　that　the　P　recovery　precipitated　was　vivianite.
