摘要：

Anaerobic　granular　sludge　bed　membrane　bioreactor　(AnGMBR)　with　simulated　domestic　wastewater　was　studied　at　room　temperature.　With　the　influent　COD　of　260mg/L,　the　effluent　COD　of　AnGMBR　could　remain　stable　under　30mg/L;　Even　if　the　HRT　was　reduced　to　5h,　it　could　still　meet　the　level　A　Emission　Standard.　The　total　methane　conversion　of　AnGMBR　was　between　0.234　and　0.271L/g　CODR,　about　61%　to　70%　of　the　influent　COD　was　converted　into　methane.　The　particle　size　and　mechanical　strength　of　granular　sludge　were　not　different　during　the　operation　of　AnGMBR,　and　granular　sludge　could　keep　stable.　After　a　period　of　continuous　operation,　AnGMBR’s　TMP　kept　stable　at　about　35kPa.　The　performance　of　membrane　was　restored　effectively　after　cleaning.　The　energy　consumption　required　for　the　fluidization　of　granular　sludge　in　AnGMBR　was　lower,　and　the　permeate　water　was　the　main　energy　consumption　required　part.　The　energy　output　could　meet　the　energy　demand.　Thus,　the　AnGMBR　system　had　great　potential　as　an　energy　positive　wastewater　treatment　system.　©　2018,　Science　Press.　All　right　reserved.
