Aeration and oxygenation equipment is a new type of water aeration equipment that has emerged in recent years. It is a new type of three-dimensional aeration and oxygenation technology. The aeration tube is generally a microporous tube made of polymer materials. The diameter of the micropore is generally about 0.01 to 0.05. When underwater, due to surface tension, water will not penetrate into the tube, and the pressure is 0.2 to 0.3 MPa during operation. The clean air (oxygen) is extruded from the micropores, and countless micro-bubbles with a diameter of 0.5-2mm are formed in the water, which form a mist-like spiral in the water, and the diffusion distance is about 1.5-3m.

The main principles of this technology are: First, through aeration, the oxygen produced by algae in the water body is exchanged from the surface of the water body to the bottom of the pond; the second is to increase the contact area between the air and the water body and increase the dissolved oxygen in the water body by rising air bubbles; high efficiency. The third is that the charged gas itself is partially dissolved in the water, which increases the dissolved oxygen in the water body, especially in special aquaculture or in the case of deep water, it has a good effect on the dissolved oxygen in the lower water body, making the dissolved oxygen And nutrients are evenly distributed throughout the water body to ensure the healthy growth of aquatic organisms. It effectively solves the problem of oxygenation in high-density, industrialized and intensive aquaculture.





The water tiller is a new type of technology introduced from Japan. It is a new type of aquaculture machinery that can improve the ecological environment of the water body, reduce energy consumption, and increase the production and quality of aquaculture. Currently used more in Japan. By promoting water circulation, while increasing the dissolved oxygen in the water, it can effectively improve the water quality, reduce the content of harmful substances, and increase the total amount of plankton and the utilization rate of bait. The principle of the water tiller is to generate a water flow extending to the water surface through the rotation of the paddle wheel of the machine, forming a rising circulating water flow in the center of the machine, so that the water at the bottom of the water body can be guided and lifted to the water surface, absorbing oxygen and sunlight. Then dive to the bottom.

In this way, the water body can be fully exposed to ultraviolet rays, which enhances the effect of ultraviolet rays on the water body, eliminates various bacteria such as green algae and Escherichia coli floating in the water, and promotes the reproduction and growth of beneficial algae and plankton in the water body. Microorganisms and remaining bait gather together, grow into harmless groups, and become food for fish, forming a perfect food chain, reducing the amount of bait and improving the utilization rate of bait. Also through the circulation of the water body, an effect similar to opening a window for ventilation is achieved in the water body, so that some low-molecular-weight substances are emitted from the water body, which can purify the water body, eliminate odor and blisters, reduce cod and bod and The nitrogen content makes the water clear.
