Studies on development and scale up of hybrid anammox reactor

新建了L体积为6.0的改进型复合式厌氧氨氧化反应器。在反应器下部安装机械搅拌器，以50~100rpm的速度轻轻搅拌厌氧氨氧化颗粒污泥。在反应器的上部安装了聚酯无纺布。在非织造布上附着了细小的厌氧氨氧化颗粒污泥，成功地防止了厌氧活性污泥的冲刷，在体积氮负荷为20.7 kg-N/m~3/d、水力停留时间极短的条件下，最终获得了最大的体积脱氮效率为20.7 kg-N/m~3/d。4个小时。

An improved hybrid anammox reactor with 6. 0 L volume was newly constructed. Mechanical stirrer was installed in the lower part of reactor and gently stirred anammox granular sludge with 50 to 100 rpm. Polyester non-woven strip was installed at the upper part of reactor. Fine anammox granular sludge was attached on the nonwoven and the washout of anmmox sludge could be prevented successfully.Maximum volumetric nitrogen removal rate of 20. 7 kg-N/m^3/d was finally obtained under volumetric nitrogen loading rate of 20. 7 kg-N/m^3/d with extremely short HRT of 0. 4 hours.
