Water quality improver and preparation method thereof

Abstract

The invention discloses a water quality improver and a preparation method thereof. The water quality improver is prepared from the following raw materials in parts by weight: 30 to 40 parts of soybean, 40 to 50 parts of corn, 20 to 30 parts of composite biological enzyme, 15 to 25 parts of bacillus subtilis, 10 to 20 parts of enterococcus faecalis, 18 to 25 parts of photosynthetic bacteria, 10 to 18 parts of bacterium nitrobacter, 15 to 23 parts of oxygen producer, 17 to 23 parts of ion exchanger, 1 to 1.5 parts of wall-broken yeast powder, 22 to 30 parts of nano-silver, 11 to 15 parts of HA salt, 5 to 8 parts of microelement, 2 to 4 parts of vitamin, 5 to 10 parts of rhodotorula glutinis, and 33 to 45 parts of medical stone powder. The water quality improver provided by the invention is simple in preparation method, low in cost, and capable of reducing bottom mud organic matters of aquaculture water, thickening an aerobic layer, accelerating growth and reproduction of aerobes and decomposition of organic pollutants, and can provide micronutrient required for normal growth of aquatic products so as to improve the quality of the aquatic products.

Description

technical field [0001] The invention relates to the technical field of water quality improvement, in particular to a water quality improver and a preparation method thereof. Background technique [0002] Aquaculture is an important part of my country's national economy. Mariculture, as a pillar industry of aquaculture, has made important contributions to the construction of the national economy and the improvement of people's living standards. However, with the rapid development of the marine aquaculture industry, problems such as sea area pollution, aging shrimp ponds, black and odorous bottom sediment, and the outbreak and prevalence of large-scale catastrophic viral diseases have been quickly exposed, making people question the traditional predatory farming model.

Problems solved by technology

However, with the rapid development of the mariculture industry, problems such as sea area pollution, aging shrimp ponds, black and smelly bottom mud deposition, and the outbreak and prevalence of large-scale catastrophic viral diseases have been quickly exposed, making people question the traditional predatory farming model.

[0003] The traditional breeding mode, especially the high-density farming mode, mostly consumes a large amount of high-protein feed and maintains the production mode at the cost of polluting the pond itself and the nearshore environment. In addition, farmers use a large amount of disinfectants, Shrimp medicines such as antibiotics, and even human medicine for fish (shrimp), the dosage is getting higher and higher, and the toxicity of the medicine is getting stronger and stronger. , the vicious circle of getting sicker and sicker

In aging ponds, toxic chemicals such as breeding residues, feces, dead animals and plants, and disinfectants and antibiotics have been deposited on the bottom of the pond for many years, forming black sludge. The sludge is rich in organic matter, and anaerobic microorganisms dominate. The increase accelerates the anaerobic decomposition of organic matter, consumes a large amount of oxygen in the water, produces NH3, H2S, NO2 and other toxic substances, which affects the normal growth and development of prawns, and the black sludge contains a large number of pathogenic bacteria, parasites and harmful organisms. eggs, which increases the transmission route of the disease source in the pond, increases the amount of fish (shrimp) medicine used in the production process, and reduces the quality of aquatic products
