FIELD: sewage-purifying facilities.

SUBSTANCE: the invention is pertaining to the field of sewage-purifying facilities, in particular, to facilities of a thermal deaeration of sewage. The deaerator of sewage contains a cylindrical body with a central funnel for the flashing steam withdrawal and a sewage delivering unit mounted tangentially to the body. The latter consists of two sections, the first of which represents a uniform chamber containing a steam feeding zone made in the form of a steam nozzle and a mixing zone made in the form of a convergent pipe chamber with the connecting pipes to feed in the deaerated sewage.
