摘要

为了考察短程硝化反硝化的影响因素，对短程硝化反硝化快速启动和稳定运行的影响因素，采用实时控制手段研究。结果表明：通过DO和pH联合实时控制，低DO条件下可以实现短程硝化反硝化快速启动。启动成功的短程硝化污泥，过度曝气对NO2 --N积累影响较大。合理控制曝气时间，应用实时控制策略，控制NH4 +-N刚刚氧化完成时停止曝气，可保证NH4 +-N完全氧化，防止NO2 --N进一步氧化。实时控制可实现短程硝化，而且可以维持短程硝化稳定运行。

Abstract

In order to investigate the influence factor of short cut nitrification and denitrification

the rapid startup and steady operation of the short cut nitrification and denitrification with real time control were studied. The results show that the short cut nitrification and denitrification can be rapidly setup by the control of DO and pH cooperated with low DO. The excessive aeration has negative effect on the accumulation of NO -2-N for primary short cut nitrification and denitrification sludge. With real time control and reasonable aeration time

the ammonia can be oxygenated completely and the nitrite can not be oxygenated when aeration stops and ammonia oxygenation just completes. Thus the real time control strategy not only realizes the short cut nitrification and denitrification

but also maintains such steady operation.
