增氧机的增氧途径主要有两个:一是通过搅水造成池水垂直循环,使溶氧在表底层水均匀分布;二是在溶氧过低时,直接增加池水的溶氧量,使池水中的有毒气体(硫化氢、氨)快速向空气中逸散。因此,正确使用增氧机,不但可以预防和减轻鱼类浮头,而且可以改善水质,加强池塘物质循环,促进浮游生物繁殖,提高鱼类新陈代谢强度,增加鱼产量。
There are mainly two ways to increase oxygenation of aerator: one is to make vertical circulation of water by mixing water, make the dissolved oxygen evenly distributed in the bottom water of the table; the other is to directly increase the dissolved oxygen of water when the dissolved oxygen is too low Poisonous gases in the water (hydrogen sulfide, ammonia) quickly evaporate into the air. Therefore, the proper use of aerator can not only prevent and reduce the floating head of fish, but also improve the water quality, enhance the material circulation of the pond, promote the multiplication of plankton, increase the metabolic intensity of fish and increase the fish production.
