摘要
研究了Ni^(2+)、Co^(2+)、Zn^(2+)、Fe^(2+)对厌氧微生物生长的促进作用,以最大比产气速率为指标,确定了添加的适宜浓度。试验表明,通过添加微量元素可大大缩短UASB厌氧反应器中厌氧污泥的培养粒化过程的时间。
The paper studied on promotion functions of Ni2+,Co2 ,Zn2+,Fe2+ for the generation of anaerobic microbes. Regarding highest efficiency of air generation as indicator .determined the appropriate concentration of microelements, ft was proved by experiments that, by adding microelements, the duration for anaerobic sludge's change and coagulation in UASB anaerobic reaction units would be shortened dramatically
