AUFWUCHSTRAEGER ZUR ERHOEHUNG DER BIOMASSEKONZENTRATION IN SCHACHTARTIGEN VERTIKALREAKTOREN

摘要

The invention relates to the biological purification of waste water (effluent) by the activated sludge process, the activation tank, which is constructed as a tower- or shaft-type vertical reactor being furnished with growth supports for increasing the biomass concentration. Better utilisation of the available oxygen supply is to be achieved. According to the invention, in a vertical reactor, comprising a shaft and a central pipe, growth supports are arranged as flow baffles on the central pipe. The flow baffles effect an intensified mixing in the upflow region and thus a breaking up of macro flocs and an improved oxygen utilisation.
