一种MBR用于启动CANON工艺的方法
摘要：
一种MBR用于启动CANON工艺的方法属于城市生活污水脱氮处理与再生领域。本发明采用MBR反应器，仅接种普通活性污泥，在限氧条件下，通过调整曝气量、曝气时间和无机碳的浓度，经过亚硝化启动及稳定运行阶段、CANON工艺启动阶段、CANON工艺负荷提高阶段，在46天内，CANON工艺启动成功，经过76天，总氮去除负荷最高可达0.41kgN/m3/d，平均为0.38kgN/m3/d，成功实现了CANON工艺的快速启动及高效稳定运行。
摘要（英）：

The invention relates to a CANON (Completely Autotrophic Nitrogen removal Over Nitrite) process starting method for an MBR (Membrane Bioreactor) and belongs to the field of the denitrification treatment and regeneration of municipal domestic sewage. According to the method, the MBR is only inoculated with ordinary active sludge, a CANON process is started successfully in 46 days by a nitrosification start-up and stable-operation stage, a CANON process start-up stage and a CANON process load increase stage through adjusting aeration, aeration time and the concentration of inorganic carbon under the condition of limited oxygen, the total nitrogen removal load can reach 0.41kgN/m<3>/d to the maximum and is 0.38kgN/m<3>/d to the average after 76 days, and then, the quick start and efficient and stable operation of the CANON process are successfully realized.
