Problems solved by technology

[0005] Oxygenates commonly used in the prior art have disintegrants, binders, and lubricants, which are all chemical products. Although they are beneficial to the manufacturing process of water body oxygenates, they cannot adsorb ammonia nitrogen, Hydrogen sulfide and algae toxins, and these chemical products are dissolved in the aquaculture water, which will affect the internal quality of fish and shrimp
In addition, in the prior art, there is no relevant record of composite microbial oxygenates

Abstract

The invention belongs to the technical field of aquiculture and discloses a compound microbiological oxygenate for removing ammonia nitrogen in aquatic water and a preparation method of the compound microbiological oxygenate. The oxygenate is prepared from the following raw material components in parts by weight: 15-25 parts of zeolite powder, 10-15 parts of chlorite, 10-15 parts of citric acid, 15-20 parts of a powdery bacillus subtilis, photosynthetic bacterium and EM bacterium mixture, 5-15 parts of a proteolytic enzyme, 5-15 parts of silicate, 20-25 parts of sodium percarbonate, 5-10 parts of quicklime, 1-4 parts of ferrous sulfate, 3-5 parts of dextrin, 3-5 parts of starch slurry and 15-20 parts of a protective agent. The oxygenate disclosed by the invention is suitable for sterilizing, oxygenating and preventing and treating diseases in aquiculture and can be used for improving the water quality, reducing the ammonia nitrogen content in a water area, improving the water level transparency, improving the substrate and purifying water.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound microbial oxygenator for removing ammonia nitrogen in aquaculture water and a preparation method thereof. Background technique [0002] The excrement and food residues of aquaculture animals are the main pollution sources of aquaculture nursery ponds and grow-out ponds. They accumulate at the bottom of the ponds for many years and are decomposed into ammonia nitrogen, nitrite, hydrogen sulfide and other harmful substances under the action of harmful bacteria. , resulting in foul odors in ponds, overgrown germs, and frequent occurrence of aquatic animal diseases. [0003] In the process of aquaculture, the traditional oxygenation method can no longer meet the needs of the aquaculture industry. The powerful oxygenation machine is easy to injure fish and shrimp, and the distribution of dissolved oxygen is uneven. The general oxygenation method cannot achie...
