FIELD: technological processes.
SUBSTANCE: invention relates to aerobic biological treatment of domestic waste water with suspended active sludge with hydraulically automatic mode of recirculation rate control depending on single volumes of non-uniformly supplied waste water for purification and can be used in separate buildings, for example, private houses, cottages, homesteads, etc. Invention comprises a method for aerobic biological treatment of domestic waste water with suspended active sludge with hydraulically automatic mode of recirculation rate control depending on single volumes, non-uniformly supplied for purification of waste water of households, and device for its implementation. Device for aerobic biological treatment of waste water with suspended active sludge with hydro-automatic mode of recirculation rate control depending on single volumes of non-uniformly supplied waste water of private houses and night mode of denitrification comprises receiving aerotank with aerator, which are located in common housing with vapor-proof cover and communicating with each other, primary settling tank, then a secondary settling tank equipped with a bubbling dispenser – a aerodischarge, for dosed uniform discharge of purified water outside the plant, and a compressor located in the vapor-insulated jacket, receiving aerotank and primary settler are interconnected by partition and made communicating in upper and lower zones by means of holes in partition, at that receiving aerotank and secondary settling tank are separated by partition with lower hole.
EFFECT: invention provides significant increase in reliability of operation, reduced operating costs, reduced power consumption for waste water treatment, simplified design of treatment plant, improved quality of waste water treatment due to intensified methods of biological effect on waste water.
