Problems solved by technology

Among them, (a) only has the effect of killing bacteria (and viruses, protozoa), because these disinfectants react with organic matter (such as humic acids) in water to produce a variety of harmful substances, causing secondary pollution, and causing damage to aquatic economic animals. Growth brings harm, and these disinfectants are greatly affected by pH value, organic matter or metal ions, and are easy to form halogen nitrogen and other substances in water sources with high ammonia nitrogen content, so that the disinfected virus is still active, so the effect is often not obvious; (b) It will cause secondary pollution, and the use of green malachite has been banned; (c) Although it has the dual effects of disinfection and purification of water, the effect is not ideal and the cost of use is too high

Embodiment 1

[0023] At room temperature, chlorine gas is slowly passed into about 35% (weight percent) KOH solution, and stirred slowly until the chlorine gas is saturated and overflows. Add an appropriate amount of solid KOH to the reaction solution, stir until KOH is completely dissolved, cool with ice water, and filter to remove white crystals. The available chlorine content in the filtrate was determined by iodometric method.

[0024] Get above-mentioned filtrate, under vigorous stirring condition, slowly add the Fe(NO 3 ) 3 , control the temperature at about 20°C, stir and keep warm for about 1 hour, stop stirring, and filter. The filtrate is potassium ferrate solution. The potassium ferrate content of the solution was determined by the chromite method.

Embodiment 2

[0026] Take the potassium ferrate solution of known concentration prepared by the method in Example 1, add potassium hydroxide solid to saturation, cool down to about 15°C, fully separate out the crystals, and filter to obtain the crude purple-black potassium ferrate.

[0027] The crude product was dissolved in batches with a small amount of 3mol / L KOH solution, and transferred to a saturated KOH solution cooled with an appropriate amount of ice water for re-precipitation. After filtering, the filter cake was washed with benzene, ethanol and ether, and then vacuum-dried to obtain potassium ferrate crystals.

Embodiment 3

[0029] Get the potassium ferrate solution of known concentration prepared by the method of Example 1, add an appropriate amount of deionized water, the AEO-15 of solution total amount 15% (percentage by weight), stir evenly, measure the pH value of the solution, with It is advisable not to be lower than 9.0 (if less than 9.0, then adjust with 3mol / L KOH solution), and a potassium ferrate solution with a concentration of 0.1% (percentage by weight) is prepared.

Abstract

A composite disinfectant for culturing aquatic products contains potassium (or sodium) perferrite, excipient, and / or pH regulator, stabilizer, adhesive, talc powder and magnesium stearate. Its advantages are high effect on disinfecting, enriching oxygen in water, and removing heavy metals, organic substances and harmful suspended substances, and no poison.

Description

(1) Technical field [0001] The invention relates to the technical field of aquaculture disinfection, purification and water quality improvement, in particular to a disinfectant composition for aquaculture and its application. (2) Background technology [0002] In the process of aquaculture, aquatic economic animals are often attacked by bacteria, fungi, viruses, and protozoa and cause disease outbreaks; The deterioration of the water body environment affects the growth of animals; environmental pollution makes the content of heavy metals and other toxic elements in the water body environment exceed the standard, such as: lead, cadmium, copper, mercury, arsenic, etc., seriously affecting the growth of aquatic economic animals. Deposition causes food safety problems and endangers human health. Therefore, purification and disinfection are very important in the process of aquaculture. At present, there are many types of disinfectants used in farming, such as: (a) halogen-conta...
