In　this　study,　an　outer　surface　modified　polyvinylidene　fluoride　(PVDF)　hollow　fiber　membrane　(HF-PVDF-CNT)　was　prepared　by　coating　with　dopamine　(PD)　and　multiwalled　carbon　nanotubes　(CNTs),　to　solve　the　problems　of　the　instability　of　pure　CNT　mats　fabricated　by　filter　coating　methods　and　membrane　fouling　in　wastewater　treatment.　The　modified　membrane　was　assessed　and　characterized　by　various　methods,　including　studies　of　its　top　surface　and　cross-sectional　morphology,　wettability,　functional　groups　and　electrical　conductivity.　The　CNT　material　stability　was　evaluated　during　backwashing.　The　antifouling　and　filtering　abilities　of　the　unmodified　and　modified　membranes　were　tested　by　monitoring　the　change　in　TMP　and　the　rejection　performance　for　different　contaminants　during　filtration　in　bovine　serum　albumin　solution　(BSA),　sodium　alginate　solution　(SA)　and　humic　acid　solution　(HA).　Furthermore,　HF-PVDF-CNT　and　electro-assisted　HF-PVDF-CNT　membranes　were　employed　as　the　basic　separation　units　in　an　anaerobic　membrane　bioreactor　(AnMBR)　system　and　an　anaerobic　electrochemical　membrane　bioreactor　(AnEMBR)　system,　respectively.　Characterization　of　the　HF-PVDF-CNT　membrane　indicated　that　the　CNT　mats　exhibited　good　stability,　electrical　conductivity　and　wettability.　In　filtration　experiments　using　BSA,　SA　and　HA　solutions,　the　HF-PVDF-CNT　membrane　showed　an　obvious　improvement　compared　with　the　HF-PVDF　membrane　in　antifouling　performance.　During　its　application　in　the　AnMBR　and　AnEMBR　systems,　the　electro-assisted　HF-PVDF-CNT　membrane　had　greater　effects　than　the　HF-PVDF-CNT　membrane　on　reducing　fouling.
