| Abstract: | The main cause of floating upward of sludge is discussed. It occurs in a municipal wastewater plant. Large quantity of nitric nitrogen flows into the secondary sedimentation tank which produces N2 by denitrification, as is believed to be the main cause of floating upward of sludge in this plant. Measures against this problem are put forward, such as increasing the amount of the discharged sludge, decreasing the amount of the aerated air, etc. |
