Compounded oxygen producer for removing nitrite in aquatic water and preparation method

Abstract

The invention belongs to the technical field of aquaculture and discloses a compounded oxygen producer for removing nitrite in aquatic water and a preparation method. The oxygen producer is prepared from components in parts by weight as follows: 40-50 parts of oxygen production ingredients, 24-38 parts of a compound microbial agent, 5-29 parts of an adsorbent, 1.0-2.5 parts of a growth accelerant, 7-10 parts of a traditional Chinese medicine admixture, 0.02-0.12 parts of a synergistic agent, 1-3 parts of a stabilizer and 1.4-2.2 parts of a sustained-release agent; the compound microbial agent comprises denitrifying bacteria, trichoderma harzianum, bacillus amyloliquefaciens, bacillus laterosporus, bacillus subtilis, rhodococcus erythropolis, silicate bacteria, streptococcus faecalis and bacillus coagulans. Multiple microbial agents are compounded in the oxygen producer, and the compounded oxygen producer can effectively remove nitrite, has the functions of inhibiting pathogenic bacteria in the aquatic water and improving digestion of intestinal tracts of aquatic animals and has better popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a compound oxygen enhancer for removing nitrite in aquaculture water and a preparation method. Background technique [0002] In recent years, aquaculture has developed rapidly, especially in artificial freshwater aquaculture, most of which are ponds or factory constructions, which are closed and the water body is static for a long time. The oxygen content and nitrite content in the water body affect the water body environment It is very large, which is directly related to the output of aquaculture, especially with the development of high-density aquaculture, a large amount of organic matter such as fish and shrimp excrement and residual bait is deposited on the bottom of the water, which makes the oxide layer on the surface of the bottom of the pool thinner, and the reduction of the lower layer The layer becomes thicker and the redox potential decreases. During t...

Problems solved by technology

[0004] The application of biological treatment methods to control nitrite in water has achieved good results. However, most of the current technologies use a single microbial strain to control water quality, and the degradation efficiency is not high enough, which has limitations. Therefore, various microorganisms Combining the optimal proportion of bacterial agents, using their interaction and mutual influence to maximize their group advantages, in order to achieve the purpose of efficient and rapid degradation, has also become a difficult problem and a research hotspot in breeding technology

However, the existing water purifier has a single function and cannot meet the requirements of high-density aquaculture. Therefore, it is of great significance to develop a multifunctional water purification agent.
