FIELD: purification of colored sewage of water reservoirs, rivers from petroleum products; water preparation, and purification of industrial flows from dye works. SUBSTANCE: sewage containing substances which make sewage look colored is filtered using carbon fibrous material in filtration zone by periodically substituting contaminated carbon fibrous material by purified. Contaminated carbon fibrous material is regenerated with live steam at lower pressure during purification process. Method is economical and allows for high degree of purification. EFFECT: improved purification method. 10 cl, 3 dwg, 3 ex
