the DO of the oxic stage is 5~8 ppm, the nitrification reaction rate is not stabile, we think the high DO weak the active of the anoxic bacteria in the sludge, until we lower the DO of oxic stage to ~3 ppm, and the nitrification reaction is stabile, the denitrification reaction rate will be 40~50%.
