In　this　study,　we　developed　a　loose　nanofiltration　catalytic　membrane　(LNCM)　by　incorporating　nitrogen-doped　carbon　nanotubes　(NCNT)　into　graphene　oxide　(GO)　membrane　(NCNT@GO-M)　to　activate　peroxymonosulfate　for　efficient　phosphonates　degradation　into　phosphate,　reducing　phosphorus-based　pollution　and　facilitating　P　recovery.　The　NCNT@GO-M　exhibited　superior　permeability　(76.7　L　m(-2)　h(-1)　bar(-1))　due　to　its　expanded　pore　size　(1.60　nm).　It　integrated　nanoconfinement　and　surface　catalysis,　improving　the　availability　of　surface-bound　sulfate　radicals　for　rapid　Orth-P　generation　(k(obs),　1.93　s(-1)),　with　the　k(obs)　being　2.4　times　higher　than　that　of　the　NCNT　membrane　catalytic　system　and　2626　times　higher　than　the　NCNT@GO　heterogeneous　catalytic　system.　The　NCNT@GO-M　also　demonstrated　excellent　antifouling,　self-cleaning,　and　anti-interference　ability,　effectively　retaining　humic　acid　with　a　molecular　weight　exceeding　3.6　kDa　(similar　to　62%　removal　of　dissolved　organic　carbon),　making　it　suitable　for　real-water　applications.　The　development　of　LNCM　shows　great　potential　for　transforming　and　recovery　of　the　nutrients　in　wastewater.
