工厂化水产养殖中的增氧技术

工厂化水产养殖密度大、水和土地资源利用率高、水质可净化而污染少,是应用工业化方式进行水产养殖的生产模式。高效合理的增氧方式可有效增加工厂化养殖中设施与设备的效能,提高生产效率,是工厂化水产养殖的关键技术之一。本文针对水产养殖发展的新变化、新特点,论述了国内外增氧装备的结构特点、增氧方式和效果,分析了增氧技术在发展过程中存在的问题,探讨了增氧技术在工厂化水产养殖中的应用方法和创新技术的发展趋势,为进一步提高增氧技术提供参考。

Techniques of Increase in Dissolved Oxygen Level in An Industrial Aquaculture System

An industrial aquaculture system,a kind of aquaculture practiced industrial technology,is characterized by high density,saving water resources and less pollution.The efficient and reasonable increase in dissolved oxygen level can effectively improve the efficiency of facilities,equipment,and reduce the costs of production,and thus is one of the key technologies in the industrial aquaculture system.The present paper describes some characteristics of ventilative equipment and technology and the efficiency of aeration.Meanwhile,some problems of the oxygenation technology are analyzed and the trend of aeration application and innovative technology is discussed to provide information on increase in dissolved oxygen level in an industrial aquaculture system for further study.
