Abstract

Изобретение относитс к санитарной технике и может быть использовано дл биологической очистки сточных вод. Цель изобретени - повышение экономичности и уменьшение занимаемых установкой площадей. Установка содержит деаэраторы 1-5, напорные аэротенки 6-11 вторичный отстойник-деаэратор 14, гидротурбины 26, 27 и трубопровод 30 ввода активного ила. Исходна сточна вода насосом 28 нагнетаетс в аэротенк 6, куда по трубопроводу 30 одновременно поступает активный ил. Из аэротенка 6 сточна вода с илом эрлифтом 23 поднимаетс в деаэратор 1, откуда самотеком перетекает в аэротенк 7. Из аэротенка 11 сточна вода поступает во вторичный отстойник-деаэратор 14 и по трубопроводу 24 выводитс из установки. Активный ил по трубопроводу 25 направл етс в аэротенк 6. Изобретение позвол ет существенно снизить площадь земель, занимаемых очистными сооружени ми, объем земл ных работ при строительстве, а также длину коммуникаций воздухопроводов и длину трубопроводов циркулирующего ила. 2 ил.The invention relates to sanitary engineering and can be used for the biological treatment of wastewater. The purpose of the invention is to increase the economy and reduce the space occupied by the installation. The installation contains deaerators 1-5, pressurized aerotanks 6-11 secondary settling tank deaerator 14, hydraulic turbines 26, 27 and pipeline 30 for inputting active sludge. The original wastewater is pumped by pump 28 into aeration tank 6, where active sludge is simultaneously supplied through conduit 30. From aerotank 6, waste water with silt with airlift 23 rises into deaerator 1, from where it flows by gravity into aerotank 7. From aerotank 11, waste water enters secondary sedimentation tank-deaerator 14 and through pipeline 24 is removed from the plant. The activated sludge through pipeline 25 is directed to the aeration tank 6. The invention significantly reduces the land area occupied by the treatment plant, the volume of earthworks during construction, as well as the length of the duct communications and the length of the circulating sludge pipelines. 2 Il.

Эти компрессоры обеспечивают также работы всех эрлифтов по известным схемам (разводка не показана дл упрощени чертежа и сохранени большей нагл дности по элементам очистки). Дополнительна гидротурбина 27 выполн ет две положительные функции - рекуперирует энергию активного ила и осуществл ют дробление его хлопьев при прохождении через колесо турбины на более мелкие частицы, что способстThe drive of an additional compressor 29. drives compressed air through the duct 34 into the system, which reduces the power of the main compressor 17 and the power of the additional electric motor 35, compensating an insufficient part of the energy of the turbine 26 for the drive and the pump and the main compressor. These compressors also ensure the operation of all airlifts according to well-known schemes (the wiring is not shown to simplify the drawing and to maintain greater visibility over the cleaning elements). The additional hydroturbine 27 performs two positive functions — it recovers the energy of the activated sludge and splits its flakes as it passes through the turbine wheel into smaller particles, which contributes to
