包埋固定化硝化菌在不同DO下的硝化规律研究
Nitrification Characteristics with Immobilized Nitrifiers in Different Dissolved Oxygen
【摘要】 在流化床反应器中使用包埋固定化硝化菌进行高氨氮废水的降解实验,在不同DO下考察和比较氨氮,亚硝酸氮和硝酸氮浓度随时间的变化规律和反应速率大小,以及亚硝酸氮和硝酸氮的反应速率随底物浓度的变化,认为DO=4.0mg/L时,亚硝酸氮的生成速率和积累率最大,平均速率为26.3mg/L.h。
【Abstract】 An ammonia-degradation experiment using immobilized nitrifiers pellets in a fluidized bed reactor was conducted to observe and compare relations between ammonia, nitrite, nitrate concentration and time, and calculate their reacting velocities. The relations between reacting velocities of ammonia, nitrite, nitrate and substrate concentration were also analyzed. The producing rate and accumulation rate of nitrite was the biggest with average of 26.3 mg/L.h when DO was 4.0mg/L.
