The aerator is a kind of equipment that drives the working parts through the power source such as motor or diesel engine, so that the "oxygen" in the air can be quickly transferred to the aquaculture water. It can make comprehensive use of physical, chemical and biological functions, which not only solves the problem of fish floating head caused by anoxia in pond culture.
But also can eliminate harmful gases, promote convection exchange of water bodies, improve water quality conditions, reduce feed coefficient, and improve the vitality and primary productivity of fish ponds, thereby increasing stocking density, increasing feeding intensity of cultured objects, promoting growth, greatly increasing yield per mu, and fully achieving the purpose of increasing aquaculture income.
When the temperature rises in spring, the decomposition of organic matter in water is accelerated, so quicklime can be sprinkled in the whole pool. Start the aerator at the right time to increase oxygen, and keep the dissolved oxygen in the pool water above 5 mg/L. After wintering, the initial use time of the aerator should not be too long to reduce the stress caused by bottoming out. At this time, changing the bottom medicine can be used as a supplement to the aerator.
Extended data:
Lavoisier's discovery of oxygen was inspired by the priest. 1774, lavoisier made oxygen through the experiment of synthesis and decomposition of mercury ash (HgO), and made a systematic study on it. It is found that it can synthesize many acids with many nonmetallic simple substances, so it is named "acid gas".
Through the experiment of oxygen, lavoisier put forward the theory of combustion oxidation, overthrew the phlogiston theory, launched a famous chemical revolution in the history of chemistry, and made chemistry stand upside down in the form of phlogiston theory. Therefore, although he was not the first person to discover oxygen, Engels called him "the person who really discovered oxygen".
