摘要

利用序批式反应器（SBR）接种短程硝化和厌氧氨氧化污泥处理实际生活污水，在间歇低氧曝气条件下实现了CANON工艺的启动。同时，保证适宜的温度和污泥浓度对处理效果及系统的稳定也很重要。该运行模式下，可实现对亚硝酸盐氧化菌（NOB）的抑制淘洗，短程硝化和厌氧氨氧化为主导反应，自养脱氮体系稳定。系统稳定运行后污染物去除效果良好：进水总氮和氨氮质量浓度为63.9 mg·L-1和62.7 mg·L-1，出水总氮和氨氮质量浓度为12.3 mg·L-1和7.6 mg·L-1，总氮和氨氮去除率为77.8%和86.7%，总氮去除负荷达0.16 kg N·（m3·d）-1。试验研究为间歇低氧曝气运行模式推广应用于城市污水自养脱氮提供了参考。

Abstract

The CANON(completely autotropic nitrogen removal over nitrite) process has been received abroad attention in wastewater treatment recent years.In the study

a Sequencing Batch Reactor(SBR) was used to treat domestic wastewater using intermittent aeration with low dissolved oxygen(DO).After inoculating partial nitrification sludge and anammox sludge

the reactor was started-up successfully under appropriate temperature and sludge concentration.By using intermittent aeration with low DO

the system achieved the inhibition and elimination of nitrite-oxidizing bacteria(NOB).The harmonious effect of partial nitrification and anammox made the system stable.In the stable phase

the reactor had a good performance on the contaminant removal.With the influent concentrations of total nitrogen and ammonia of 63.9 mg·L-1 and 62.7 mg·L-1

the effluent of them were 12.3 mg·L-1 and 7.6 mg·L-1 and the removal rates of them were 77.8% and 86.7%

respectively

with the volume loading of total nitrogen removal of 0.16 kg N·(m3·d)-1.Thus

the experiment provided references for the application of the operation mode in autotrophic nitrogen removal of wastewater.
