FIELD: fish industry. SUBSTANCE: apparatus has main circulation circuit including water container for keeping aqueous organisms, pump, mechanical filter, water purification system with biological filters and oxygenator, water treatment system, water medium acidity correction device and regulation system. Water treatment system has independent water circulation circuit communicated with main circulation circuit and having water accumulator, pump and electrolyzer unit. Water acidity correction device has water electrolytic fraction reservoirs communicated with electrolyzer and main circulation circuit. Apparatus is further provided with closed circuit for circulation of liquid organofluoric composition-oxygen carrier. Closed circuit has pump, mechanical filter, degasifier, oxygenator and open chutes disposed within container. All components of closed circuit provide for adequate gas exchange between water and organofluoric composition. Water purification system has anaerobic denitrifier apart from biological filters. EFFECT: improved keeping conditions by using natural waters of any hardness, safe correction of water acidity, increased efficiency in saturating water with oxygen and high quality biological purification of water. 2 cl, 1 dwg |
