FIELD: chemistry.
SUBSTANCE: in equilising tank of purifying device sewage is supplied and then pumped into activation reservoir. From activation reservoir waters after purification are supplied into secondary sedimentation tank, and from it, after sedimentation of remaining silt, into output hole. If the level of sewage waters in equilising tank decreases lower than established minimal level process of activation is automatically stopped, and excess of slit is pumped from activation reservoir. As a result of the following increase of the level of sewage waters in equilising tank above the established level, pumping of slit is stopped, and process of activation is resumed.
EFFECT: possibility of exploitation in case of uneven inflow of sewage waters with preservation of high purification ability.
