Paper Title:
Application of pH, DO and OUR Control for Short-Cut Nitrification
  Abstract

A sequencing batch reactor was employed to treat ammonia wastewater, the pH, DO and OUR were adopted to monitor the start of short-cut nitrification. The results showed that the start of short-cut nitrification was achieved in 31days, ammonia consumption rate was higher than 90% and nitrite accumulation rate was higher than 85%, when pH, DO and OUR were applied to monitor and determine the aeration time, under the condition of temperature was 30°C. With ammonia shock loading conditions, OUR curve couldn’t indicate the end of short-cut nitrification exactly. But real-time control using pH and DO could achieve a stable shortcut nitrification under steady stage and ammonia load shocking stage.
