However, in actual aquaculture, the dissolved oxygen in the pond water is sometimes very low, resulting in weak activity and poor feeding ability of the cultivated fish. At this time, an impeller aerator is needed. Then buy an impeller aerator to improve the fish pond. Why not take the output? Main business: impeller type aerator production, impeller type aerator sales, impeller type aerator manufacturers, impeller type aerator supply.

The oxygen generator can be seen in the switching position, so that the abnormal conditions can be pulled down immediately when it is tued on. If the fish pond is 10 acres When the above, you can install one at both ends of the fish pond. The wires of the fish pond oxygenhar to the gate switches must use the cable produced by a regular manufacturer, usually using a 3 × 1. In particular, it is easy to hypoxia.

After putting the oxygenulers down the fish pond, pay attention to check if Turbine Aerator the impeller is balanced into the water, and the impeller is balanced by the method of three float irrigation, and the impeller should be around 1 cm. The fish pond below 5 acres can be used for. The correct boot mode should be before the oxygen situation occurs, so that the fish can not be hypoxic, which is conducive to its healthy growth. It is also easy to have an oxygen.5 kW oxygen generators.

Only by proper use can guarantee its utmost role. After fertilization, it should be tued on, in short, as long as there is an oxygen situation, it should be tued on. When the weather is rapid, it is easy to hypoxia, and it is easy to apply a manure to the fish pond.

The power supply used by the fish pond produced by the feeding machine manufacturer is a three-phase electricity of 380 volts, so it must pay attention to electricity safety. Some fish farmers will start when they find the fish float, which is incorrect, and the fish has been harmful. In general, it is easy to hypoxia in the middle of the night.

n aquaculture production, fish pond aerators are used more and more widely, but some fishermen still do not understand its working principle, which is blind and arbitrary in actual operation. Therefore, only by first understanding how it works can you truly grasp how to use it.

Design principle of fish pond aerator

The purpose of a fish pond aerator is to increase dissolved oxygen in the water. This includes both the solubility and solubility of oxygen. Electrons include three factors: water temperature, water salt content, and oxygen partial pressure. The latter includes frequency impeller aerator  three factors: the degree of unsaturation of dissolved oxygen, the contact area and method of water-gas, and the motion state of water. The steady state of waters in which water temperature and water salinity are present. Therefore, in order to increase the production of oxygen in the water body, it is necessary to directly or indirectly change the partial pressure of oxygen, the contact area and method of water-gas, and the movement state of water.

1. Use mechanical parts to stir the waters to facilitate flow exchange and interface updates.

2. Disperse into small water droplets with water, spray the popular air, and increase the contact area of ​​water and air.

3. Disperse the gas into the microbubbles by negative pressure inhalation and push it into the water.

The fish pond aerator is designed according to these principles, taking measures to promote the dissolution of oxygen or taking more than two measures.

Continuous rain and more boot

In summer, if it rains continuously, the light conditions are poor, the photosynthesis intensity of phytoplankton is weak, and the supply of dissolved oxygen in the water is low. However, the respiration of various organisms in the pond and the decomposition of organic matter require a large amount of oxygen, resulting in a shortage of dissolved oxygen in the water. , it is easy to cause the floating head of the breeding object. In addition, on cloudy and rainy days, the water is sometimes crystal clear, with few phytoplankton and many water fleas, which almost eat up the phytoplankton in the pond, resulting in lack of oxygen in the pond due to lack of photosynthesis sources of oxygen.

When the "oxygen debt" is large, it is necessary to switch on more

That is, it has been sunny for a long time, the water temperature of the pond is high, the water quality is excessively fertilized due to a large number of feeding, the transparency is low, the water is rich in organic matter, the oxygen difference between the upper and lower layers is large, and the lower layer is too oxygen-deficient (oxygen debt).

At this time, in addition to prolonging the startup time, it is necessary to add new water to the pond, otherwise, the water quality will be excessively fertilized or the water quality will be deteriorated and cause hypoxia.

Does not tu on when baiting

Therefore, when the machine is tued on, the bait will be rotated to the center of the pond and Pond Aeration Equipment accumulated with the excrement, so that it is not easy to be eaten, resulting in waste of bait; do not tu on the machine in the evening, because the photosynthesis of phytoplankton is about to stop at this time, and oxygen cannot be added to the water. The dissolved oxygen in the upper and lower layers of water is evenly distributed, and the dissolved oxygen in the upper layer cannot be replenished after the reduction, while the dissolved oxygen in the lower layer is quickly consumed, which in tu accelerates the rate of dissolved oxygen consumption in the entire pond.

In short, when to start the machine and the length of the start-up time should be flexibly controlled according to the weather, the specific conditions of the farmed animals, and the load of the aerator. Generally, open at noon on a sunny day, open in the early moing on a cloudy day, open in the middle of the night with continuous rainy days, not open in the evening, and open the floating head early, the weather is hot and the start time is long, the weather is cool and the start time is short, the start time in the middle of the night is long, the start time at noon is short, and the load surface is large. Long time, small load surface and short startup time strategy.

The air flotation machine completes a complete set of sewage treatment process by releasing air bubbles into the water, a large number of air bubbles adhere to the solid suspended matter,  aquaculture Aerator follow the buoyancy and rise to the surface, and are eliminated by the scraping system to complete a complete set of sewage treatment process, but not all sewage types are applicable. Treated in a flotation machine. The suspended solids (impurities) in sewage are divided into soluble substances and insoluble substances.

The soluble substances are directly dissolved in the water, such as sugar, insoluble substances such as dust particles and so on. Air bubbles are easily attached to the surface of insoluble substances and rise to the water surface with buoyancy. Different customers have different requirements. Generally speaking, through dosing, PAC (flocculant) and PAM (coagulant aid) can make the effect better. For soluble substances, biochemical treatment can be used according to different water quality. If it is sewage treatment similar to inorganic salts and other substances, we need to use RO reverse osmosis. Simply put, the air flotation machine is the equipment suitable for industrial sewage treatment. According to different water outlet requirements, other supporting facilities may need to be added.
