DESCRIZIONE
The invention relates to the field of commercial fish farming and can be used for breeding food fish in closed loop plants. The claimed plant consists of aquatic organism breeding units cooperating with each other by means of water pipes and data switching channels, a water stabilizing tank, a mechanical filtration unit, a biological water enrichment unit, a denitrification biofilter, a nitrification biofilter, a ventilation duct, a UV irradiation unit, a boiler Water pH stabilizer unit, a pump, a first air compressor, fish tanks, a water reserve tank, a second air compressor, a fresh water addition unit, an effluent discharge unit and sediments from the biological water replenishment unit, the denitrification biofilter and the nitrification biofilter, a first shutter, a second shutter, a third shutter and a level control unit comprising an IBM-compatible personal computer, a water parameter monitoring and control unit, a suction pump mpe for conveying sediments from the biological water enrichment unit, the denitrification biofilter and the nitrification biofilter, a mixing valve, a pump of the biological water enrichment unit and a pump of the water reserve tank. On the IBM-compatible personal computer of the automatic filling unit, the software ""Control program for process engineering in modern fish farms"" is installed. The expected technical effect from the application of the notified facility is an increased stocking density of the species of fish.
