FIELD: sewage facilities.
SUBSTANCE: station includes a housing made in the form of a horizontally located cylinder divided into compartments, in the upper part of which there are necks, a compressor. Body is divided by vertical partitions with overflow holes into three successive compartments: receiving, aeration tank and secondary settling. Station comprises two necks, first of which is located above receiving compartment, and second—above two other compartments. External walls with inlet and outlet branch pipes, as well as vertical partitions have stiffening ribs. Aeration tank in the lower part of the housing contains an aeration system, above which a bio-loading unit is located. Third compartment is connected by airlift to the first compartment, and also contains a discharge chamber of purified water, fixed on the inner side of the outer wall of the station, which is also reinforced with a stiffening rib in the lower part.
EFFECT: simplified design of biological treatment plant with simultaneous increase in rigidity of its design and degree of purification of waste water.
