摘要:

It is important to achieve short-cut nitrogen removal from municipal wastewater for saving energy and carbon source. However, a low temperature (10-20°C) affects the actual application of shortcut nitrogen removal from wastewater. In this study, a large pilot-scale SBR was used to treat real municipal wastewater. The goal of achieving and stabilizing short-cut nitrification at a low temperature was mainly investigated. The results indicated that through real-time control and step-feed operating pattern, short-cut nitrogen removal with nitrite accumulation rate above 95% and nitrogen removal efficiency above 96% was achieved at 11.8-25°C. The key factor of achieving and stabilizing short-cut nitrification in pilot-scale SBR was the optimization of nitrifying communities in sludge owing to long-term application of realtime control.
