To　deal　with　the　issue　of　water　polluted　by　algae,　organic　matters　and　taste　and　odor　in　eutrophic　water　of　lakes　and　reservoirs,　a　combined　process　of　coagulation-sedimentation　combined　with　biological　powered　activated　carbon　and　submerged　ultrafiltration(BPAC/SUF)was　applied　to　study　the　removal　effects　of　chlorophyll　a,　organic　matters　and　taste　and　odor,　and　to　investigate　the　membrane　fouling　characteristic　of　micro-polluted　water　sample　with　artificial　taste　and　odor　in　lab-scale.　The　results　show　that　remarkable　removal　rate　of　chlorophyll　a　could　reach　to　95.5%,　and　the　organic　matters＇　removal　efficiency　was　obviously　improved　with　the　average　removal　rate　of　31.0%　for　UV254,　30.4%　for　DOC　and　51.0%　for　CODMn,　respectively.　Better　removal　effect　on　2-MIB　and　GSM　were　achieved　with　74.8%　and　75.1%,　respectively.　The　average　taste　and　odor　level　of　treated　water　was　below　the　threshold　value.　Membrane　fouling　was　well　controlled　during　the　whole　experimental　period,　and　the　trans-membrane　pressure　was　increased　only　by　3.80　kPa.
