| 摘 要： | 为增强抗冲击负荷能力和保证颗粒污泥与废水充分混合,在上流式厌氧污泥床(UASB)反应器内三相分离器前增设强制内回流装置,形成改良UASB反应器,利用污水处理站UASB厌氧污泥,处理酒精废水。结果表明,UASB整个启动期为61 d,启动的第40天出现颗粒污泥,UASB启动期间对COD、SS的平均去除率分别为70%、11%,出水pH在6.4～7.8,挥发性脂肪酸的质量浓度降到200 mg.L-1以下,有利于后续单元对废水的处理。 |

| Abstract: | In order to strengthen the capacity of compact load and ensure fully mixing of granular sludge and wastewater,in front of the three-phase separator,the obliged back-flow device was placed in the UASB reactor to form the modified UASB reactor and using the anaerobic sludge of UASB of sewage treatment station to deal with alcohol wastewater.The results showed that running 61 d,the granular sludge turned up on the fortieth day of the start-up of UASB reactor.During this period the average removal rate of COD and suspended substance(SS) were 70% and 11%,respectively.In the effluent water,the pH was 6.4～7.8,and the concentration of volatile fatty acid(VFA) was reduced to under 200 mg·L-1,which was to the benefit of the follow-up treating unit of alcohol wastewater. |
| Keywords: | alcohol wastewater up-flow anaerobic sludge blanket reactor start-up granular sludge |
