HIGH-DENSITY ADSORBENTS OF BACTERIA, CLOSED CIRCULATORY SYSTEM CONTAINING THE SAME FOR FISH FARMING AND FISH FRY CULTURE AND FISHES FED BY USING THIS SYSTEM |
摘要 |
<p>A closed circulatory system for fish farming and fish fry culture containing high-density adsorbents of bacteria in which microbial cells of nitrifying bacteria and denitrifying bacteria are fixed at a high density. This system is composed at least of a water tank unit for fish farming, a pH-controlling unit, an oxygen-supplying unit for elevating the dissolved oxygen concentration, a nitrifying reactor unit and a denitrifying reactor unit. Water discharged from the fish-farming water tank is purified via the pH controlling unit, the oxygen-supplying unit, the nitrifying reactor unit and the denitrifying reactor unit and then returned into the farming fish-water tank. A high-density adsorbent of nitrifying bacteria, in which nitrifying bacteria cultured at a high density have been fixed, is provided in the nitrifying reactor unit, while a high-density adsorbent of denitrifying bacteria, in which denitrifying bacteria cultured at a high density have been fixed, is provided in the denitrifying reactor unit. Also, a chemical solution storage tank is connected directly to the pH-controlling unit so that the pH value of the farming water can be controlled in the pH-controlling unit with a solution of a mixture of sodium carbonate with sodium hydrogencarbonate.</p> |
