PROCESS FOR BIOLOGICAL WATER PURIFICATION WITH INTEGRATED BUFFERING

摘要

The description relates to a process for the biological purification of water in which peak loads of waste water can be purified in small installations with an improvement in the quality of purification. To this end, waste water is drawn from the secondary settlement chamber steadily over 24 hours. In addition, the normal ventilation is reset to stand-by ventilation and ventilation is interrupted to reduce the oxygen content to a predetermined level.
