摘  要：
为强化废水中烟碱的厌氧生物降解性能,对造纸法制烟草薄片产生的废水,在厌氧颗粒污泥UASB小试反应器中的生物降解进行监测和分析,测定了厌氧处理过程中烟碱的降解曲线,发现微生物对烟碱的降解过程可能涉及协同降解机理。提出了以反硝化反应强化厌氧过程中烟碱降解的思路,通过外加硝酸盐来诱导驯化厌氧颗粒污泥中硝化菌的代谢活动,经过驯化,厌氧颗粒污泥UASB小试反应器出水中烟碱浓度由120mg/L以上降至约25mg/L,同时反硝化反应促进了废水中其他有机物的深度降解,出水化学需氧量(CODCr)由约600mg/L降至200～300mg/L,反硝化强化造纸法烟草薄片废水中烟碱生物降解作用明显。

摘  要：
The biodegradation of paper-making tobacco sheet wastewater in anaerobic granular sludge UASB batch reactor was inspected and analyzed for the purpose to strengthen the anaerobic biodegradation of nicotine in wastewater,and the biodegradation curve of nicotine in anaerobic process was drawn out with the suggestion that biodegradation of nicotine might deal with the mechanism of synergistic biodegradation.Denitrification as a bio-augmentation technique was introduced into the domestication of anaerobic granular sludge.Nitrate was added into the wastewater to induce the metabolism activity of anaerobic denitrifying bacterium.The results showed that after domestication the concentration of nicotine and CODCr could be decreased from above 120 to 25 mg/L and from 600 to 200-300 mg/L separately in anaerobic granular sludge UASB batch reactor.Denitrification can increase the biodegradation of nicotine in paper-making tobacco sheet wastewater significantly.
