Method for efficiently reducing ammonia nitrogen and nitrites in aquatic water body

Abstract

The invention discloses a method for efficiently reducing ammonia nitrogen and nitrites in an aquatic water body. Organic carbon substances can artificially added to regulate the C / N ratio in the water body and enhance the quantity of heterotrophic bacteria in the water environment; microbes are utilized to assimilate inorganic nitrogen and convert ammonia nitrogen and other aquatic metabolites in the water body into the components in bacteria; and the particulate matters flocculated by the bacteria are ingested by aquatic organisms, thereby reducing the ammonia nitrogen and nitrites in the aquatic water body.

Description

technical field [0001] The invention relates to the field of aquaculture, specifically a method for efficiently reducing ammonia nitrogen and nitrite in aquaculture water. Background technique [0002] There are two types of compounds commonly found in seawater: organic compounds and inorganic compounds. Among them, inorganic nitrogen compounds mainly include ammonia nitrogen, nitrite nitrogen, and nitrate nitrogen. Nitrate nitrogen is non-toxic and the most important. Too much ammonia nitrogen and nitrite nitrogen will cause toxicity, and ammonia nitrogen is more toxic. The main problem is that molecular ammonia has no charge and has strong fat solubility. It can penetrate the body surface of farmed animals, such as the epidermis of gills, into the blood to cause poisoning. The main form of ammonia in seawater is NH 4 + Ions, the content of free ammonia (namely ammonia nitrogen) is less. There are three main ways for the formation of ammonia nitrogen: a. The residual b...

AI Technical Summary

Problems solved by technology

[0003] Nitrogen-containing organic matter, especially protein and amino acid, in the residual bait cast too much bait will be oxidized and decomposed in the pond, which not only increases the ammonia nitrogen in the water, but also consumes a large amount of dissolved oxygen in the water, resulting in hypoxia in the bottom water body

After the water body is hypoxic, the organic matter will undergo anaerobic reaction, further producing more ammonia nitrogen, which will deteriorate the water quality
