An aerator is an effective method to increase the amount of dissolved oxygen. In addition to increasing oxygen, it can also promote the circulation of water and prevent temperature stratification, chemical stratification and oxygen stratification of water. At the same time, the paddle wheel aerator must operate deep in the pond to improve the soil at the bottom of the pond, increase the oxygen in the bottom soil and avoid the generation of toxic gases, and effectively prevent the death of aquatic animals.
An aerator is a device that drives a working component through a power source such as an electric motor or a diesel engine to rapidly transfer "oxygen" in the air to the aquaculture water. It can comprehensively utilize physical, chemical, and biological functions, and can not only solve pond culture. The problem of fish floating head caused by lack of oxygen, and can eliminate harmful gases, promote convective exchange of water, improve water quality conditions, reduce feed coefficient, improve fish pond activity and primary productivity, thereby increasing stocking density and increasing feeding intensity of cultured objects. To promote growth, so that the per mu yield is greatly improved, and the purpose of increasing the income of breeding is fully achieved.
There are several types of traditional aerobic machines currently on the market:
The first is the long arm aerator: it has the combined functions of aeration, water agitation and gas explosion. It is the most widely used aerator. The annual output value is about 150,000-200,000 units, and its oxygen-enhancing capacity and power efficiency are better. Other models, but the operation noise is relatively large, generally used for large-scale pond culture with a water depth of less than 1 meter.
The second is the waterwheel aerator: it has good oxygenation and promotes the flow of water, and is suitable for deep ponds.
The third is the jet aerator: its aerobic power efficiency exceeds that of a water tanker, aeration type, and a water spray type. The structure is simple, and it can form a water flow and stir the water body. The jet aerator can make the water body gently increase oxygen, does not damage the fish body, and is suitable for aerobic use in the fry pond.
The fourth is the water spray aerator: it has a good aeration function, which can quickly increase the dissolved oxygen content of the surface water in a short time, and also has an artistic viewing effect, which is suitable for use in gardens or tourist areas.
The fifth is the aeration pump: because it is light, easy to operate and has a single oxygen-enhancing function, it is generally suitable for use in fry breeding ponds or greenhouse breeding ponds with a water depth of less than 1.0 m and an area of less than 1 mu.
Aeration and aeration technology is a new type of pond culture technology developed in recent years. Its working principle is mainly to use advanced nanotechnology to compress the air into an aeration disc distributed near the bottom of the pond through an air compressor to achieve a three-dimensional oxygenation effect from the bottom to the pond. Compared with the traditional surface mechanical oxygenation, it has the advantages of uniform oxygenation area, balanced oxygenation level, less mechanical energy consumption, and improved bottom environment effect. It has the following characteristics:
1. Form a V-shaped bubble at the bottom of the water when oxygen is added. When the water depth is about 2 meters, a V-shaped aeration disk atomized bubble can reach 3-4 meters wide; a 0.2 m diameter aeration disk can effectively reach an area of 350 square meters, and its bubble diameter is 3.5UU, the contact area with water is large, the dissolved oxygen at the bottom of the pond water can be 6-8g/L, accelerating the oxidation function of harmful substances such as ammonia nitrogen, nitrite and hydrogen sulfide at the bottom of the water body, degrading the toxicity of aquatic organisms. Side effects, inhibit excessive water enrichment and improve the living environment of aquatic products.
Second, compared with other aerobic methods, aeration and aeration are static aerobics at the bottom, which has the least impact on the normal life of cultured products, so it can increase the adaptability of cultured products, increase appetite, shorten the culture growth cycle, and stocking density. It can reach about 1.5 times of the original, and improve the quality while improving the output. Get the best economic benefits.
