Abstract
1. Способ обработки активного ила в ходе биологической очистки сточных вод, включающий транспортировку суспензии, полученной после аэрации смеси сточных вод с активным илом, в камеру отсасывания газа под действием создаваемого в камере разрежения и вводимого в коллектор воздуха, вакуумную дегазацию аэрированной смеси и ее транспортировку во вторичный отстойник, отличающийся тем, что воздух подается в нижнюю часть подающего коллектора вдоль его центральной оси в пульсирующем режиме, обеспечивающем пульсацию подаваемой суспензии с частотой 0,05-0,2 Гц. ! 2. Способ по п.1, отличающийся тем, что воздух подают со скоростью 0,1-1,0 м3 в с. ! 3. Устройство для обработки активного ила при биологической очистке сточных вод, содержащее резервуар для аэрации смеси отходов с активным илом и вторичный отстойник, соединенные между собой подающим и выпускным коллекторами через камеру отсасывания газа, которая связана с вакуумным насосом, причем подающий коллектор снабжен приспособлением для ввода дополнительных количеств воздуха в систему, отличающееся тем, что приспособление для ввода дополнительных количеств воздуха в систему обеспечивает его подачу в виде пузырьков в пульсирующем режиме в нижний конец коллектора параллельно его оси. ! 4. Устройство по п.3, отличающееся тем, что в качестве приспособления для ввода дополнительных количеств воздуха в систему линия оно содержит компрессор или воздуходувный насос, снабженный прибором, обеспечивающим заданный режим пульсации. ! 5. Устройство по п.3, отличающееся тем, что в качестве насоса используют аэрлифтный насос.1. A method for treating activated sludge during biological wastewater treatment, including transporting a suspension obtained after aeration of a mixture of wastewater with activated sludge to a gas suction chamber under the action of a vacuum created in the chamber and introduced into the collector air, vacuum degassing of the aerated mixture and its transportation into the secondary settler, characterized in that air is supplied to the lower part of the supply manifold along its central axis in a pulsating mode that provides pulsation of the supplied suspension with a frequency of 0.05-0.2 Hz. ! 2. The method according to claim 1, characterized in that air is supplied at a rate of 0.1-1.0 m3 per second. ! 3. A device for the treatment of activated sludge in biological wastewater treatment, containing a tank for aeration of a mixture of waste with activated sludge and a secondary settler, connected to each other by supply and outlet manifolds through a gas suction chamber, which is connected to a vacuum pump, and the supply manifold is equipped with a device for introducing additional amounts of air into the system, characterized in that the device for introducing additional amounts of air into the system ensures its supply in the form of bubbles in a pulsating mode to the lower end of the collector parallel to its axis. ! 4. The device according to claim 3, characterized in that, as a device for introducing additional amounts of air into the line system, it comprises a compressor or a blower pump equipped with a device providing a predetermined pulsation mode. ! 5. The device according to claim 3, characterized in that an air-lift pump is used as the pump.
