Titanium　dioxide　was　loaded　on　activated　carbon　fibers　(ACF)　with　different　surface　areas　by　using　the　residue　after　epoxy　resin　being　calcined　as　the　link　between　TiO2and　ACF,　and　their　surface　properties　and　photodegradations　of　wastewater　from　paper　mill　have　been　investigated.　TiO2powder　distributed　on　ACF　in　the　form　of　small　clusters,　and　its　surface　element　state　changed　after　UV　irradiation.　After　TiO2was　loaded　on　ACF,　the　surface　area　of　supported　catalysts　(TiO2/ACF)　decreased,　but　the　pore　structure　of　ACF　remained　well.　The　photodegradation　results　showed　that　an　increase　in　surface　area　favored　high　COD　removal　for　paper　mill　effluents;　The　best　COD　removal　was　obtained　only　by　using　TiO2/ACF2　with　moderate　surface　area　and　pore　structure　for　organic　molecules　from　the　effluents,　and　its　photocatalytic　activity　was　higher　than　suspended　P25　and　without　any　decline　when　used　repeatedly.　©　2006　Elsevier　B.V.　All　rights　reserved.
