【摘要】 集约化水产养殖条件下 ,如何净化和循环利用大量的养殖污水 ,已成为限制淡水渔业发展的瓶颈。该研究通过创新的工程设计 ,在自控生态大棚内实现多种水生动物和植物的高密度、集约化、节水化养殖。养鱼水经过红萍、蔬菜等植物的吸收以及水净化综合技术处理 ,可以循环使用。该大棚不向外排泄养殖废水 ,不仅大大节约用水 ,而且养殖密度成倍增加 ,并不构成任何环境污染更多还原

【Abstract】 Under intensive pisciculture conditions, the problem of how to purify and reuse the large amount of animal-breeding sewage has become a bottleneck that limits the development of pisciculture. Through an innovative engineering design, our research enabled us to grow several kinds of aquatic animals and plants in an automatically controlled ecological greenhouse in a high density, intensive and water-saving manner. The fish-raising sewage may be circularly reused after it is absorbed by Azolla and vegetables, as well as undergoing comprehensive treatment for water purification. This greenhouse system did not let out breeding sewage to the environment, so it not only saved a lot of water, but also doubly increased the growing density without causing environmental pollution.更多还原
