FIELD: process engineering.
SUBSTANCE: invention relates to environmental protection and can be used for purification of phenol containing sewage flows. Phenol containing sewage flows are purified by a mix containing 60 to 99 wt % of methylisobutyl ketone, 1 to 40 wt % of anisole and, is required, up to 20 wt % of mesitylene.
EFFECT: higher degree of purification.
