FIELD: waste water purification. SUBSTANCE: in a method of cleaning waste water from organic impurities by sorption with activated carbon and subsequent regeneration of worked out sorbents with extracts, as the latter, liquid subcritical carbon dioxide at 0-30 C and pressure 35.5-75.5 atm is used, and its removal is effected by way of reducing pressure until liquid carbon dioxide is converted into gaseous state. EFFECT: simplified process.
