A station for biological aerobic treatment of waste water combines in one reservoir divided by walls denitrification section with inlet section, nitrification section and gravity separation section, angled wall between nitrification and gravity separation sections, means for recirculation of reverse sludge from separation section to the inlet section, means for recirculation of sludge mixture between denitrification and nitrification sections through the upper holes in walls of sections and recirculation of sludge mixture from nitrification section to the gravity separation section through the lower hole in wall between sections, short partition, separating nitrification section and gravity separation section in the lower partition zone, device for aeration of sludge mixture in nitrification section, device for pumping off excess sludge from nitrification section to the device for its further treatment. The short partition is made bigger than vertical height of the lower hole in angled wall between nitrification and gravity separation sections and fixed vertically with formation of gap between it and angled wall, device for aeration of sludge mixture in nitrification section, fixed with its upper point in one level with the upper point of short partition. |
