Excess　sludge　fermentation　is　a　commonly　employed　method　for　carbon　sources　in　wastewater　treatment　plants,　but　its　use　as　a　carbon　source　for　chlorophenol　removal　has　been　relatively　underexplored.　In　this　study,　a　laboratory-scale　sludge　fermentation　SBR　(FSBR)　was　integrated　with　a　2,4,6-trichlorophenol　(2,4,6-TCP)　degradation　SBR　(DSBR),　resulting　in　a　stable　removal　of　2,4,6-TCP　without　the　need　for　external　carbon　sources.　In　this　coupled　system,　the　concentrations　of　volatile　fatty　acids　in　FSBR　remained　constant,　with　acetic　acid,　propionic　acid,　butyric　acid,　and　valeric　acid　concentrations　reaching　322.04　mg　COD/L,　225.98　mg　COD/L,　274.76　mg　COD/L,　and　149.58　mg　COD/L,　respectively,　and　the　acid　production　efficiency　increased　to　88.40%.　Throughout　the　110-day　operational　period,　the　activated　sludge　concentration　in　the　DSBR　was　consistently　maintained　at　3021　+/-　110　mg/L,　and　the　sludge　SVI　remained　stable　at　70　mL/g.　The　maximum　amount　of　2,4,6-TCP　removed　reached　240.13　mg/L　within　a　12　h　operating　cycle.　The　use　of　excess　sludge　fermentation　can　completely　replace　commercial　carbon　sources　for　2,4,6-TCP　removal,　leading　to　cost　savings　in　chlorophenol　treatment　and　broadening　the　applicability　of　this　technology.
