YC series waterwheel aerator

How to make the YC series waterwheel aerator become a "increasing machine"?

Through the use of waterwheel aerators in recent years, Xiaobian found that many fishermen have gone in two directions when it comes to driving aerators: one is that the aerator does not stop for 24 hours; the other is, Do not see the floating head does not turn on. In fact, the above two boot methods are definitely unreasonable. Turning on for 24 hours is not only a waste of electricity, but also a fish pond that has been turned on. Once the aerator is unexpectedly shut down, it is easy to have an anoxic floating head. If the floating head is not turned on, the aerator is obviously used as a lifesaving machine. Did not play the role of aerator.

First of all, according to the main reason of hypoxia caused by different weather, the aerator should be used reasonably.

On a sunny morning, the lack of oxygen is mainly due to the large vertical change of dissolved oxygen in the upper and lower water layers during the day, and the lower water temperature and density in the daytime are high, and the upper water temperature is high and the density is low. The upper and lower water layers cannot convect in time, and the supersaturated oxygen in the upper layer escapes the water surface without utilization. Wasted in vain; and the lower layer consumes a lot of oxygen factors. When the surface water temperature drops and the density increases at night and the convection of the upper and lower water layers is caused, the dissolved oxygen condition of the entire water layer tends to deteriorate and cause floating heads.

When the machine is turned on at noon on a sunny day, it is a combination of biological oxygen generation and mechanical oxygen supply, which makes full use of the supersaturated oxygen in the upper layer, and uses the agitator action of the aerator to artificially overcome the thermal resistance of the water, and photosynthesis produced by the upper layer Supersaturated oxygen is transported to the lower layer, and the dissolved oxygen in the lower layer is replenished in time to reduce the oxygen consumption of the lower layer water. At this time, although the dissolved oxygen content of the upper layer was lower than that before the start-up, the upper layer was still saturated with photosynthesis in the afternoon. After the natural convection of the pond water at night, the dissolved oxygen in the upper and lower water layers can still maintain a high level, which can mitigate or eliminate the threat of fish floating heads to a certain extent.

Starting at noon on a sunny day can not only prevent or reduce the floating head of fish, but also promote the decomposition of organic matter and the reproduction of plankton, and accelerate the material circulation in the pond. Therefore, in the main growing season of fish, you must seize every sunny day, insist on turning on the aerator at noon, and make full use of the supersaturated oxygen in the upper layer of water to seize the initiative to improve water quality.

The lack of oxygen on cloudy and rainy days is caused by the lack of strong photosynthesis of phytoplankton, low oxygen production, and high oxygen consumption, which causes the supply of dissolved oxygen to exceed supply and cause fish floating heads. At this time, the role of the aerator must be brought into full play, and the technology of predictive floating head can be used to aerate early. The fish must be switched on before the fish floating head to directly improve the low peak of dissolved oxygen and prevent and rescue the fish floating head.

The waterwheel type aerator is turned on in the evening on a sunny day, so that the upper and lower water layers are convected in advance, but the oxygen-consuming water layer and oxygen consumption are increased. Its effect is similar to that of a thunderstorm in the evening, which easily causes floating heads. Starting at noon on cloudy or rainy days, not only can't increase the dissolved oxygen in the lower layer water, but reduce the oxygen generation of the upper layer phytoplankton, increase the oxygen consumption layer of the pond, accelerate the oxygen consumption rate of the lower layer water, and easily cause floating heads. . Fishing proverbs are: on a sunny evening and on a cloudy day (rainy day), the "floating head machine" is turned on at noon.
