| 内容記述 | The movable aerator, which was devised by HIRATA (1968) to maintain a homeostatic condition in a culture tank, contributed to the mass production and high density culture of prawn seed production. This experiment was carried out to examine the capacity of the movable aerator for the decomposition of organic matter and the proliferation of microorganisms in a green house. The movable aerator was set in a 2,500 l tank (0.9×3.0×0.9 m). A 500 l polycarbonate tank, aerated with bubbling stone, was used as control. Organic substances were loaded as pollutants at the rate of 0.2 to 0.6 dry weight g/l. The weight of suspended substances contained in 10 l of water was measured by centrifugation, and the calorie contents were determined by bomb calorimetry. As indicators of water quality, the concentrations of inorganic nitrogen and phosphate were analized. At the same time, bacterial density was also observed. Decomposition rate of organic substances in the movable aerator tank was 0.023 to 0.034 dry weight g/day faster than in the polycarbonate tank. The concentrations of three types of inorganic nitrogen and phosphate were all higher in the movable aerator tank. The calorific values of suspended substances per 1 g dry weight increased with the advance of decomposition; and a correlation coefficient of 0.67 was obtained between the calorific values of suspended substances and bacterial density in the water. |
