Title A/O process viscous sludge reduction of inflation condition

This thesis focuses on a lot of problem generated sludge in the process of activated sludge wastewater treatment. Examine sludge reduction effect under sludge viscous inflation state in the A/O process. The sludge SVI value in this experiment is 150-290(ml/g), between maintain stable operation with the reaction, the value has a trend to decrease slowly. Water in the system and the stable operation of the state standards and zero to do blank dosage comparison earthworm flutter, flutter by adding different earthworm weight (unit weight of sludge (MLSS) in the flutter earthworm wet weight, that is, g wet weight than the flutter earthworm / MLSS), that have a certain effect of sludge reduction.
