FIELD: sewage treatment. SUBSTANCE: method for sewage treatment includes formation of froth layer on the surface of pure water by supply of water-air mixture with surfactants. Then, supplied to this layer is sewage water. Final treatment of water is effected by passing it through water-air layer containing ozone. Use of the offered method for sewage treatment by flotation filtration increases efficiency by 6-10%. Water purification efficiency may be brought up to 99.5 %. EFFECT: higher purification efficiency within a wide range in volume and nature of sewage. 4 tbl
