Abstract:
With the application of anaerobic reactors,such as upflow anaerobic sludge blanket (UASB),anaerobic baffled reactor(ABR),internal circulation(IC) reactor,etc. to the treatment of highly concentrated organic wastewater,the excessive acidification problem during its start-up and running processes has drawn people’s attentions more and more. Acidification problem has restricted the popularization of the highly efficient anaerobic reactors to a certain degree. Aiming at the causes and hazards of anaerobic acidification problems,some efficient physical,chemical and biological recovery methods are discussed emphatically,so as to provide references for the running stabilization of highly efficient anaerobic reactors.
Key words:
highly efficient anaerobic digestion,
excessive acidification,
upflow anaerobic sludge blanket,
anaerobic baffled reactor,
internal circulation reactor
摘要:
随着升流式厌氧污泥床(UASB)、厌氧折流板反应器(ABR)、内循环反应器(IC)等厌氧反应器在高浓度有机废水处理中的应用,其启动及运行过程中出现的酸化现象日益受到关注,酸化问题一定程度地抑制了厌氧反应器的推广。针对厌氧酸化问题的产生及危害,着重讨论了厌氧酸化后物理、化学和生物恢复方法,以期为高效厌氧反应器的稳定化运行提供技术参考。
