Sequential wastewater treatment plant and wastewater treatment process

摘要

The invention relates to a sequential wastewater treatment process and a corresponding wastewater treatment plant in which wastewater is successively transferred in batches to separate water absorption volumes and is stowed there for collection and / or treatment / purification. So far, separate containers have been used as water absorption volumes, which is very complex in various ways. According to the invention, at least one movable partition (6, 8) for dividing the separate water absorption volumes (1, 2, 3) is provided in a basin, a water batch being pumped from one into the next water absorption volume while the water level remains constant in the two water absorption volumes, whereby the movable partition or the movable partition walls (6, 8) are moved in the transition phase in order to bring about the required changes in volume of the water absorption volumes (1, 2, 3).
