Design and construction technology of water-purifying facilities in recirculating aquaculture system
摘要
Abstract
Water-purifying facilities are suitable for popularization and promotion at present stage in China with small investment, running low energy consumption and large unit processing advantages .In this paper, three kinds of water-purifying facilities were introduced:sedimentation tank, flotation tank and biofilter.The key technologies in design and construction process were summarized .Under the normal running condition , pH in aquaculture water was maintained below 7.5.Non-ionic ammonia, nitrite nitrogen and phosphorus were maintained at the range of 5.60-7.96 μg/L, 0.08-0.10 mg/L and 2.12-2.52 mg/L, respectively.The results showed that the control of pH and treatment effect of ammonia nitrogen in the system were good .It is proved that the design of the recirculating aquaculture system and water-purifying facilities are reasonable, which could better meet the use requirements .关键词
