Conventional　treatment　methods　of　landfill　leachate　concentrate　mainly　focus　on　the　degradation　or　removal　of　humic　substance,　which　are　prone　to　secondary　pollution　and　fail　to　meet　the　requirements　of　current　sustainable　development.　The　key　to　sustainable　management　of　landfill　leachate　concentrate　is　to　precisely　fractionate　the　existing　humic　substance　and　inorganic　salts　as　individual　resources.　Here,　electro-driven　nanofiltration　membranes　were　fabricated　by　sodium　periodate　inducing　co-deposition　of　pyrogallol　and　polyethyleneimine　on　the　loose　polyamide-based　nanofiltration　substrate　membranes　as　high-performance　anion　conducting　membrane.　The　pyrogallol/polyethyleneimine　composite　coating　layer　endowed　the　electro-driven　nanofiltration　membranes　with　reduced　surface　negative　charge　and　specific　areal　electric　resistance　for　enhanced　anion　transfer.　During　the　electro-driven　nanofiltration　process,　the　fabricated　membrane　with　a　30-min　co-deposition　exhibited　an　extremely　fast　anion　transfer　rate　and　outstanding　fractionation　performance　with　99.08　​%　humic　substance　recovery　of　99.08　​%.　Particularly,　the　fabricated　membrane　showed　stable　separation　capacity　over　an　8-cycle　electro-driven　nanofiltration　operation,　demonstrating　a　low　fouling　propensity.　Our　study　sheds　light　on　the　strategy　to　fabricate　high-performance　electro-driven　nanofiltration　membranes　via　co-deposition　of　pyrogallol　and　polyethyleneimine,　paving　the　way　to　sustainable　treatment　of　landfill　leachate　concentrate.　©　2024　The　Authors
