What are the effects of impeller aerator on environmental protection?

Classify：News center Release time：2024-07-22

With the leapfrog development of the economy today, our living standards are constantly improving. However, the pressure on the Earth's environment is also increasing day by day. The alarm bell for environmental degradation has been sounded, and the concept of "low-carbon environmental protection" for the future environment is becoming more and more deeply rooted in people's hearts. For the impeller aerator, it can continue to maintain the normal flow of artificial lakes in rivers that have been polluted to a certain extent for a certain period of time, eliminate eutrophication of lakes and reservoirs, eliminate black, odorous, and other problems, improve the ecological utilization rate of sewage, classify river water and rainwater landscape water, and play an important role in environmental protection.

The impeller aerator can effectively increase oxygen within a certain range. Its powerful power can transport oxygen to over 30 meters away, forming a cycle, eliminating stratification, and adapting to the growth habits of fish and shrimp. It is different from the impeller aerator, as we generate certain waves during operation without damaging the pond foundation. So when installing the aerator, please try to lower your head as much as possible and keep a distance of no less than 30cm from the bottom of the tank. And during work, the water flow direction is positive and the rotation direction is correct. If not, then any two phase wires should be replaced.

During the operation of the impeller aerator, no one is allowed to enter the water to avoid electric shock accidents caused by motor leakage. And when eliminating faults in the water, the power must be cut off. In the mixing room, air and water are mixed and then quickly discharged under the action of centrifugal force. Due to the strong jet of the impeller aerator, it leads to effective convective circulation and the air is divided into many small bubbles.

Four main functions of fish pond aerator in the process of scientific aquaculture!

In general, in aquaculture ponds, you will see aquaculture aerators installed at the center position. Some will be equipped with impeller aerators, some will be equipped with waterwheel aerators, and some will be equipped with water jet aerators

Do you know their main function? Let's learn together;

What are the main roles of fish pond oxygenation in scientific aquaculture?

Let's talk about the answer first: there are four answers;

Function 1: Conventional oxygenation

Function 2: Aeration exhaust

Function 3: Adjust water temperature

Function 4: Increase yield

Now let's analyze and explain in detail!

1: Conventional oxygenation

This is also the most important function of the fish pond aerator. In order to increase the yield per acre of aquaculture, the density of aquaculture is generally increased during the breeding process. At this time, more oxygen needs to be contained in the water body. At this time, the aerator comes into play by rapidly rotating and stirring the water body through the impeller, quickly integrating fresh air from the atmosphere into the water body, thus achieving the goal of rapid oxygenation of the water body;

2: Aeration exhaust

The rotating impeller also increases the agitation of the water body, transferring the upper water pressure to the lower layer. While conveying fresh air, it also discharges the exhaust gas at the bottom of the pond, providing comprehensive isolation for the gas content in the pond water. Harmful and unfavorable gases for aquaculture are discharged, and fresh air is injected to maintain the activity and health of the water body, thereby maintaining the safety of the aquaculture environment;

3: Adjust the water temperature

In the process of aquaculture, the issue of water bodies is more easily overlooked, especially in extreme environments such as summer and winter. If the temperature of the water body exceeds the aquaculture temperature range, it can cause large-scale aquaculture deaths. Therefore, the aerator not only injects more oxygen into the water body during this process, but also agitates the water body to balance the water temperature. It can also control the temperature of the upper and lower layers of the water body to reach the equilibrium point, avoiding the situation where the temperature of the upper layer of the water body is high and the temperature of the lower layer is too low, especially in deep aquaculture ponds;

4: Increase production

The fourth main function of fish pond aerators is to increase production. After installing aerators, the breeding density of ponds of the same size can be expanded by one or more times. In other words, the weight of aquaculture produced per unit breeding time can reach one time, which can create greater value for aquaculture. Therefore, most aquaculture ponds are now equipped with fish pond aerators;

These are the four main functions of fish pond aquaculture aerators. Do you know that if your pond is not equipped with a fish pond aerator, then give it a try!

How to use aerator reasonably in aquaculture? How to choose the most suitable aerator?

The function of the aerator is not only to increase the dissolved oxygen in the water, but also to facilitate the concentration of organic debris, feces, algae residue, and residual bait in the pool due to water agitation, increasing the habitat and feeding space for shrimp.

At present, the widely used aerators in shrimp farming include waterwheel aerators, impeller aerators, fish pond aerators, etc. Plowing and surging machines are new types of aerating machinery in aquaculture. When they are started, they can generate a circulation effect between the upper and lower water layers through stirring, forming a three-dimensional circulating water flow, thereby breaking the stratification of the water body and improving the oxygen deficiency at the bottom.

Different types of aerators have their own characteristics. Using different aerators in the same pond can not only save electricity costs but also achieve complementary oxygenation effects; For example, in the high-level pond culture of Penaeus vannamei, bottom microporous aerators or aerators are installed, combined with water wheel aerators to eliminate water stratification; The rectangular low-level soil pool can be treated with a combination of surge machines and water wheel aerators for oxygenation.

The installation position of the aerator in the shrimp pond should be determined based on the characteristics of different types of aerators, combined with the size, shape, and water depth of the shrimp pond. It should be able to promote circular flow of the pond water. The start-up time and frequency of the aerator manufacturer in the clean feeding area should be determined according to the seedling density and algae concentration. Under normal circumstances, the aerator should be started twice a day within 20 days after seedling release, and 2-3 hours before dawn and noon. After 20-40 days of cultivation, the start-up time can be extended as needed; In the later stage of aquaculture, due to increased self pollution of the water body, the total weight of shrimp increases, and it needs to be turned on all day.

In addition, on rainy days, the startup time and frequency should be increased to maintain the dissolved oxygen level in the water above 5mg/L. After heavy rain, the aerator should be started to exchange the upper and lower layers.

When feeding, the machine should be stopped for 0.5-1 hour to facilitate shrimp feeding. In high-density precision aquaculture of Vannamei shrimp or shrimp factory farming in high-level ponds, oxygen concentrators or liquid oxygen devices can be installed in places where conditions permit. The oxygen concentration in the water is much higher than that of power oxygenation, which can be used to supplement dissolved oxygen or emergency situations in the later stage of aquaculture.
