摘要：

Hybrid　processes　of　conventional　treatment　and　PAC　addition　on　immersed　ultrafiltration　membrane　was　evaluated　for　the　treatment　of　taste　and　odor　in　algal-rich　water　simulated.　The　results　confirm　that　in　the　immersed　ultrafiltration　membrane　bioreactor　PAC　has　sufficient　adsorption　and　long-term　biodegradation　of　dissolved　organic　materials　which　cannot　be　filtrated　by　ultrafiltration　membrane　alone.　UF-PAC　processes　could　intensify　the　conventional　treatment.　Through　the　advanced　treatment　of　UF-PAC,　the　algae　cells　are　all　removed　and　the　average　removal　efficiencies　of　DOC,　UV254　and　CODMn　increase　by　19.6%,　30.0%　and　28.3%　compared　with　the　conventional　treatments,　respectively.　And　2-MIB　and　geosmin　in　effluent　both　fall　below　the　odor　threshold,　which　guarantee　the　effluent　quality.　Membrane　fouling　was　mitigated　by　both　conventional　treatment　and　PAC　in　the　membrane　bioreactor　the　transmembrane　pressure　increases　by　only　9　kPa　in　30　d.
