UASB反应器废糖蜜在启动阶段的废水处理和生物制氢
Wastewater Treatment and Biohydrogen Production in Attached and Suspended-sludge UASB Reactors During the Start-up Period by Malasse
摘要
Abstract
Conventional up-flow anaerobic sludge blanket(UASB)reactor and modified UASB reactor were studied and compared during the start-up period in the removal of chemical oxygen demand(COD)and fer-mentative biohydrogen production.Maximum COD removal rate of 82 and 68.4%and maximum hydrogen pro-duction rate(HPR)of 188.99 and 117.03 mmole-H2 L-1h-1 for modified UASB and conventional UASB reac-tors were observed,respectively.Besides,the maximum specific hydrogen production rate(SHPR)of modified UASB was 45.03 mmol H2/g VSS-d at HRT of 6 h while the maximum SHPR of UASB was 30.36 mmol H2/g VSS-d at hydraulic retention time(HRT)of 8 h.Ethanol-type fermentation was predominant in modified UASB while acetic acid-type fermentation was predominant in conventional UASB.Modified UASB showed sta-ble biohydrogen production and managed to with stand the washout by retaining a high amount of biomass.关键词
