Preparation method of aquaculture bactericide

Abstract

The invention provides a preparation method of an aquaculture bactericide, and belongs to the technical field of aquaculture. The preparation method includes mixing dispersions of chitosan quaternaryammonium salt in a dispersion medium with activated carbon. A modifier for preparation of the chitosan quaternary ammonium salt is 2,3-epoxypropyltrimethylammonium chloride. Activators are glycolic acid and L-zinc lactate. The bactericide comprises the chitosan quaternary ammonium salt, sodium percarbonate, citric acid, soda ash and modified activated carbon. The preparation method of the aquaculture bactericide provided by the invention is easy in control of operation and less in energy consumption and system operation loss, and the activity of biological raw materials is not destroyed. The prepared bactericide integrates the effects of water quality improvement, disinfection, anti-inflammation and sterilization, has the advantages of no toxic effects, strong ability of catching bacteria,wide application range in acid-alkali environment, good adsorption effect and large amount of bacteria removal per unit, and obviously reduces the amount of the drug and the treatment cost.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a preparation method of an aquaculture fungicide. Background technique [0002] With the continuous improvement of the degree of intensification of aquaculture in my country and the sharp increase in the species and density of aquaculture, there are quality problems in aquatic product aquaculture, such as serious pesticide residues, ammonium nitrogen, nitrite, coliform bacteria, pathogenic bacteria and Toxic elements exceed the standard. The widespread use of chemicals such as disinfectants, water quality improvers and algaecides has caused pesticide residues in aquatic products to exceed the standard; a large amount of fertilizer has caused ammonium nitrogen and nitrite in the aquaculture water to exceed the standard. Although chemicals have made great contributions to the development of aquaculture, their long-term use has brought about problems such as environm...

AI Technical Summary

Problems solved by technology

With the development of the aquaculture industry, people are constantly screening new disinfectants. At present, there are still many shortcomings in existing disinfectants, such as chlorine-containing disinfectants, which are easily affected by changes in organic matter and pH in water, and have harmful effects on utensils. Corrosive effect, also highly toxic to fish, the effective chlorine contained in the chlorine preparation reacts with the water body to form various halides, and produces a variety of non-volatile halogenated organic compounds such as trihalomethanes, etc. At the same time, the chlorine preparation reacts with ammonia in the water to form Chloramine, not only has no killing effect on pathogens in water, but also has side effects on aquatic organisms after reaching a certain concentration; the bactericidal effect of quaternary ammonium salts is easily affected by water hardness, and the bactericidal effect is poor under acidic conditions; Although iodine preparations have good bactericidal effect, they are easily affected by light and temperature, and are easy to evaporate and fail; although phenolic disinfectants are less affected by organic matter, they have poor bactericidal effect, pollute the environment, and are toxic and corrosive
