Abstract:

Based on the successful starting up of the two bioreactors, the removal efficiency of anammox bioreactor couldn′t synchronizally increase when the average volumetric ammonia loading rate is oversized. A new treatment system has been set up by nitrous nitrification bioreactor and anaerobic ammonia oxidation bioreactor. The parameters of the bioreactor system are as follows: average ammonia removal rate is more than 95%, volumetric total ammonia removal rate is 20.1mg/ (L·d), total organic compound removal rate is about 90%.

Key words: denitrification, nitrous nitrification, anaerobic ammonia oxidation, bioreactor

摘要：

研究评估了生物亚硝酸型硝化反应器与Anammox反应器组成的新型脱氮系统的可行性及该系统的脱氮效率。在两个反应器成功启动的基础上，得出反应器容积负荷率过大时，厌氧氨氧化反应器的去除能力未能同步的得到提高；脱氮系统总的NH₄⁺-N平均去除率达95%以上，系统的容积氨氮去除率为20.1mg/（L.d），有机物的总去除率稳定在90%左右。
