| 摘要 |
An integral activated sludge wastewater treatment system has a vessel having at least one internal baffle dividing the vessel into at least one treatment chamber and at least one settling chamber. The settling chamber is at least partially defined by a first wall of the baffle. The treatment chamber is at least partially defined by a second wall of the baffle. A recycle pump is provided for recycling aerated wastewater from the treatment chamber back into the settling chamber and inducing a downward sludge velocity in excess of the velocity that would be caused by gravity alone.
