| Abstract: | The characteristics of anaerobic granules degrading saline dye wastewater were investigated in a laboratory-scale upflow anaerobic sludge blanket (UASB) reactor at (55±1)℃.Experimental results demonstrated: when ambient flocculent digester sludge was used as seed,HRT(hydraulic retention time)was 12 h,salinity was 50 000 mg/L ,influent COD_ Cr (chemical oxygen demand)was 900～ 1 000 mg/L ,and reactive red 2(RR2) dye concentration was 100 mg/L.The quasi-steady state of the UASB reactor was achieved after 78 running days.The COD_ Cr and RR2 removal rates were above 44% and 85% respectively.The diameter of the thermophilic salt-tolerant anaerobic granular sludge was from 1.0～ 2.0 mm, bacilli,cocci and filamentous bacteria were found. |
| Keywords: | saline dye wastewater thermophilic anaerobic UASB reactor RR2 and granular sludge |
