摘    要:通过厌氧氨氧化速率的测定研究了温度、pH值和有机物对厌氧氨氧化污泥活性的影响.结果表明:温度和pH值对污泥的厌氧氨氧化活性有明显影响,最佳温度为30~35℃,在20~30℃之间,厌氧氨氧化速率与温度之间的关系可以用修正的Arrhenius方程式描述;最佳pH值为7.5~8.3,在pH值为7.0~9.0之间,厌氧氨氧化速率与pH值之间的关系可以用双底物双抑制剂模型描述;厌氧氨氧化污泥中存在着异养反硝化菌,有机物的存在会导致其与厌氧氨氧化菌之间的基质竞争.

关 键 词:厌氧氨氧化  厌氧氨氧化活性  基质竞争  异养反硝化

Abstract:Influence of temperature, pH and organics on ANAMMOX activity was investigated through measuring the anaerobic ammonia oxidation rate of sludge. Results show that temperature and pH could influence ANAMMOX activity dramatically. The optimal temperature was between 30-35 degrees C , and the relationship between the anaerobic ammonia oxidation rate and temperature can be described by revised Arrhenius formula during 20-30 degreee C. The optimal pH was between 7.5 - 8.3, and the relationship between the anaerobic ammonia oxidation rate and pH can be described by two substrates and two inhibitors model during pH 7.0 - 9.0. There was substrata competition between the heterotrophic denitrification bacteria and ANAMMOX bacteria when organics in the
Keywords:anaerobic ammonia oxidation  ANAMMOX activity  substrata competition  heterotrophic denitrification
