According to data, 4570g of oxygen is consumed to oxidize 1000g of ammonia into nitrate. Therefore, the bottom must be changed to stabilize the water. The compensation depth of dissolved oxygen in water = transparency x 1.Manufacturers of aquatic aerators introduced the status of dissolved oxygen at the bottom of the water: the integration of air into the water body, including water exchange and aeration, artificial mechanical aeration and natural aeration by wind, etc.0 mg/L below 100 cm.
Therefore, efforts to study and explore the bottom oxygenation technology of aquaculture water bodies are extremely important for improving water quality conditions, raising the level of aquaculture, and increasing the production and benefits of aquaculture. One of the best ways to improve bottom quality is to increase the dissolved oxygen in the bottom., accounted for about 10% of the total source of dissolved oxygen; second, oxygen production by photosynthesis , Wholesale farm aerator Suppliers Accounting for about 90% of the total source of dissolved oxygen.
The change of bottom quality is the condition that leads to the change of water quality.5, the dissolved oxygen in the surface of the water body is supersaturated within 40 cm, and the dissolved oxygen is less than 2.. When the dissolved oxygen in the water body is lower than 3mg/L, the nitrification reaction is hindered, and the low dissolved oxygen is often in the middle and lower layers of the water body. Some data show that plankton are distributed on the surface of the water body, 1.2m above the water surface.
Beyond this range, photosynthesis is extremely weak and almost no dissolved oxygen is produced. The abundant dissolved oxygen in the bottom layer accelerates the harmlessness of harmful substances-reducing ammonia nitrogen, eliminating hydrogen sulfide, stabilizing pH, and reducing chemical oxygen consumption. The surface layer of aquaculture water has high dissolved oxygen, and the bottom dissolved oxygen is extremely low, but the bottom dissolved oxygen consumption and demand are very large, which is a prominent contradiction in the aquaculture water. At the same time, the decrease of dissolved oxygen leads to the increase of CO2. Good bottom quality is the basis of stable water quality. , As a result, the pH drops
