摘要

用辐射共聚产物为载体将氨氧化细菌水生丛毛单胞菌（Comamonas aquatic LNL3）固定化

研究了温度、pH、碱度、溶解氧等因子对短程硝化氨氧化速率的影响

建立了四个主要影响因子的动力学模型

分析了它们对短程硝化过程的灵敏度。实验结果表明

该固定化氨氧化细菌短程硝化最适温度、pH、碱度、溶解氧分别为30℃、8.5、7.14（碱度/NH4+-N）和4.03mg/L

灵敏度分析表明

状态参数对固定化氨氧化细菌短程硝化过程的氨氧化速率的影响为pH值>温度>碱度>DO。

Abstract

An new kind of ammonia-oxidizing bacteria

Comamonas aquatic LNL3

was screened out and immobilized by radiation-copolymerized carrier.Four factors affecting the short-cut nitrification

i.e.temperature

alkalinity and dissolved oxygen(DO) concentration

were been investigated.The kinetics model of short-cut nitrification for immobilized Comamonas aquatic LNL3 was established and sensitive degree of the affecting factors was discussed.The result show that optimal conditions are 30℃ of temperature

pH 8.5

alkalinity/NH4+-N of 7.14

and DO concentration of 4.03 mg/L.In addition

for short-cut nitrification the four affecting factors are in a sequence of pH > temperature > alkalinity > DO concentration.
