Abstract：

This　study　reported　the　NaCl-enhanced　anaerobic　fermentation　with　cation-exchange　resin　regeneration　waste　liquid　(CRWL)　as　alternative　NaCl　source　for　waste　activated　sludge　(WAS)　disposal　and　carbon　recovery.　Through　4-day　CRWL-enhanced　anaerobic　fermentation　at　Na+　concentration　of　0.34　mol/L,　the　Na+-caused　sludge　disintegration　triggered　numerous　release　of　dissolved　organic　matters　(DOMs),　i.e.　371.6　mg/g　VSS,　with　composition　distribution:　acetic　acid　(28.2%)　＞　butyric　acid　(16.1%)　≈　valeric　acid　(17.8%)　≈　proteins　(16.4%)　＞　propionic　acid　(14.4%)　＞　unknown　(3.2%)　＞　carbohydrates　(3.9%).　Satisfying　chemical　conditioning　performance　for　the　fermented　sludge　was　observed　at　the　FeCl3　dosage　of　0.3　g/g　DS,　attributing　to　the　roles　of　double-layer　compression　and　electric　neutralization.　The　capillary　suction　time　(CST)　and　sludge　cake　moisture　content　were　decreased　to　60.3　s　and　75.1%,　against　those　of　607　s　and　93.5%　before　conditioning,　respectively.　Such　＇treating　waste　by　waste＇　strategy　could　provide　numerous　environmental　and　economic　benefits.　©　2020　Elsevier　Ltd
