FIELD: technological processes. ^ SUBSTANCE: invention is intended for cleaning of streamflows. Method for cleaning of river current consists in dispersed supply of water-air mixture in discharge jets with control of flow from nozzles 6 of aerators 5 under perforated elastic screen 12 with through holes 13 under a sharp angle in direction 7 of flow 1 motion. Perforated elastic screen 12 is previously laid along river bottom for its whole width, fixing one of its edges to pipeline 3 above nozzles 6 of aerators 5, and the other one, located downstream, is left free. ^ EFFECT: provision of effective enrichment of water current with oxygen dissolved in water to increase its self-cleaning ability, elimination of anaerobic conditions in near-bottom layers of water by means of its aeration and circulation. ^ 5 dwg |
