PROCESSING METHOD OF WATER CONTAINING SURFACE-ACTIVE SUBSTANCES Russian patent published in 2010 - IPC G21F9/04 

FIELD: power industry.

SUBSTANCE: invention refers to processing of liquid nuclear waste (LNW), can be used during processing of water containing surface-active substances (SAS), namely special laundry water. Water containing surface-active substances is supplied to evaporator plant of additional evaporation of floor drain after salt content in it is 60 ÷ 150 g/dm³ and there performed is combined evaporation of water containing surface-active substances and floor drain by keeping them in the ratio of 1 : (3÷10); after salt content is 150 ÷ 350 g/dm³, still bottom is pumped from time to time to storage tank at the working evaporator plant till salt content value is 60 ÷ 150 g/dm³.

EFFECT: improving reliability and simplifying the treatment process of special laundry water evaporation and reducing periodicity of acid washings of evaporator plant of floor drain treatment.
