摘要:研究不同型式的增氧机性能,可使生产者根据不同养殖对象与模式针对溶氧的需求,选择配置合适的增氧方式。通过对使用最为广泛的叶轮式、水车式、射流式和曝气式增氧机产品性能的池塘实效试验,分析比较各类增氧机性能、工作特性和适用范围。结果表明,养殖水体溶解氧主要来自浮游植物的光合作用;叶轮式、水车式和射流式增氧机应用于服务水域,其增氧能力远远不能满足该水域养殖鱼类的氧需求,但可满足养殖鱼类的应急氧需求;曝气式增氧机因没有应急增氧作用和水体搅拌能力而不适合四大家鱼等常规鱼种的养殖需要。

Abstract: With the development of aquaculture aeration technology, the continuous appearance of various types of aerobic machineries adapts to the needs of different aquaculture. Researching the performance of different types of aerators can make the producers select appropriate aeration manners, which is based on the demand of dissolved oxygen according to different culture objects and models. According to the experiment of the effect of impeller aerator, paddlewheel aerator, jet aerators and aeration aerator in the pond which are most widely used, we analyzed the aerator performance, operating characteristics and applicability. The result showed that the dissolved oxygen of aquaculture water mainly comes from the photosynthesis of phytoplankton. When impeller aerator, paddlewheel aerator and jet aerators apply to its service water, their aerobic capacities are far from the oxygen demands of the fishes which cultured in the water, however, it can meet the emergency oxygen demands of cultured fishes. Aeration aerator is not suitable for culturing the four major Chinese carps because it is lack of emergency oxygen effect and water mixing capacity.
Key words: impeller aerator; paddlewheel aerator; jet aerator; aeration aerator; oxygen effect; integrated assessment
