In　order　to　improve　the　removal　efficiency　of　pollutants　by　ultrafiltration　(UF)　membrane,　the　experiment　has　been　carried　out　based　on　the　combined　use　of　adsorption　of　powered　activate　carbon　(PAC)　and　filtration　of　UF　for　advanced　treatment　of　drinking　water.　The　results　showed　that　UF　could　remove　turbidity　effectively,　while　it　could　not　remove　dissolved　organic　matter　and　lower　molecular　weight　pollutants　well.　Adding　PAC　to　the　system　enhanced　the　removal　efficiency　of　UF　for　CODMn,　UV254　and　the　larger　the　amount　of　PAC　added,　the　higher　the　removal　efficiency.　It　also　showed　that　under　the　same　addition　amount　of　PAC,　the　organic　content　of　effluent　decreased　firstly　and　then　was　steady　during　the　course　of　the　operation.
