ANBON生物脱氮反应器
Anbon Bio-reactor is consist of two series connected reactors. The main tower removes the most nitrate from the wastewater with fast growing bacteria, while the secondary reactor further removes the remaining nitrates with slow growing bacterial. The A/O system set after Anbon Bio-reactor provides an advanced treatment and ensures the discharge reach the standards.
Anbon denitrification biology technology relies on Anbon bio-reactors and granular denitrification bacteria. The concentration of granular bacteria is as high as 30~40 g-SS/L. The system’s volume load during lab experiments reaches 70kg-N/(m3·d), while industrial volume load reaches 10kg-N/(m3·d). The nitrate removal rate reaches 90%.
性能指标
该工艺具有以下特点：
（1）装置容积效能高，最高容积负荷达到70 kg-N/(m3·d)，是传统反硝化工艺（0.5 kg-N/(m3·d)）的上百倍，总氮去除率高达98%；
（2）耐浓度冲击负荷高，最高进水硝氮浓度可达2000 mg-N/L,约为传统反硝化工艺（≦300 mg-N/L）的七倍；
（3）容积效能高，可大幅缩小反应器体积，减少占地面积，工程投资小；
（4）运行费用低，利用自身产气进行自搅拌，免用传统反硝化所需的搅拌机/推流器；
（5）经济性能优良，菌体以颗粒污泥形态存在，可大大强化泥水分离效果，削减工程设备。
