DEVICE WITH CLOSED CYCLE OF WATER SUPPLY FOR CULTIVATION OF TRADE FISH SPECIES

摘要

The invention relates to the industry of industrial fish breeding and can be used for growing commercial fish species in installations with a closed water supply cycle. The proposed device consists of interconnected by means of water pipes and information and switching channels of hydrobiont cultivation units, stabilization water tank, mechanical filtration unit, biological water enrichment unit, denitrification biofilter, nitrification biofilter, aeration channel, ultraviolet irradiation unit, boiler, water pH stabilization unit , pump, first air compressor, fish tanks, reserve water tank, second air compressor, unit supply of fresh water, wastewater removal unit and sedimentary fractions from biological water enrichment unit, denitrification biofilter and nitrification biofilter, first shutter, second shutter, third shutter, level automatics unit including IBM compatible computer, water tracking and control unit , pump for pumping sedimentary fractions from a biological enrichment unit for water, a denitrification biofilter and a nitrification biofilter, a mixer, a pump for a biological enrichment unit water and pump reserve water tank. In addition to the operating system, the computer program "PROGRAM OF MANAGEMENT OF TECHNOLOGICAL PROCESSES IN MODERN FISHING COMPLEXES" is installed on an IBM compatible computer of the level control unit. The technical result expected from the use of the claimed device is to increase the level of landing of commercial fish species.
