FIELD: treatment plants.
SUBSTANCE: invention relates to treatment of waste water and can be used for aeration of water discharged by industrial enterprises into environment, for example in natural water bodies. Water aeration device comprises a nozzle equipped with shut-off head, flexible brushes, axis, to which is attached a turbine with blades, installed coaxially inside cylindrical nozzle with possibility of rotation relative to axis of discharge mixing chamber. Outlet part of nozzle is connected to a confuser and communicated with a diffuser via mixing chamber, and air feed pipe with valve communicates with atmosphere.
EFFECT: technical result is significant increase of degree of aeration of water, low cost of water treatment and reduction of required number of holes in nozzle.
