FIELD: water purification; chemical mechanical engineering. SUBSTANCE: invention relates to purification of natural and waste water from impurities, in particular, from oil-containing wastes. In a known installation containing closed hydraulic line with successively included primary floatation chamber, one or several secondary floatation chambers, pump, and saturator, each preceding chamber is connected with succeeding one through "liquid-liquid"-type ejectors, all entries for carrying liquid into which are connected in parallel to saturator outlet. Entry for aspirated liquid from ejector connected with entry into primary floatation chamber is designed for feeding liquid being primarily cleaned, in particular, water. To more efficiently take off water from each preceding chamber, floatation chambers are made in the form of isolated from each other pans each separated by hollow partitions into two subchambers, height of partitions being less than that of pan wall. Chambers have similarly disposed one inlet opening in bottom part of the first subchamber, one opening in bottom part of the second subchamber to communicate with partition hollow, and at least one outlet opening in the top zone of partition hollow. EFFECT: increased water cleaning degree. 3 cl, 4 dwg |
