    The invention relates to fish management, namely to devices for keeping aquatic animals for a long time. A device for keeping aquatic animals is known, including an animal reservoir, aeration devices and a closed circulation loop with a filter and a pump 1}. In this device, water is circulated through the tank with animals and coarse water purification from contaminants contained in it, however, this does not remove toxic gases from the water that interfere with the normal life of animals. Closest to the proposed technical entity is an apparatus for keeping aquatic animals, containing an animal reservoir filled with water, a control unit for treating water located outside the reservoir, including an aeration device in the dyes and an ammonia remover. connections, a discharge pipe for supplying water from the lower part of the tank to the control unit, a return pipe for supplying water from the control unit to the tank and a pump for circulating water through the tank control unit and piping 12. In this device, when water is circulated through the control unit, poisonous substances found in the water, gases present in the water are released from it, in particular the removal of ammonia and carbon dioxide. As for the substances dissolved in water, they are in the control the block is not removed, which makes it impossible to maintain the life of aquatic animals for nine long periods of time. The purpose of the invention is to increase the duration of keeping of aquatic animals. In order to achieve the delivered task, a device for keeping water. ANIMAL containing a tank for aquatic animals, filled with water, a control unit for water treatment located outside the tank, including a device for aerating water and a device for removing ammonia compounds from water, a discharge pipe for supplying water from the lower part of the tank to the control block, return pipe for supplying water from the control unit to the tank and pump for circulating water through the tank, the control unit, the pipeline and the pipelines, is supplied with an oxidizing agent supply source, connected connected to the branch pipe before the device for removing ammonium compounds 1 from water during the water supply, and the control unit additionally contains a device for removing soluble organic compounds from water and a device for converting the oxidative agent into substances non-toxic to animals, both of which are are located after the device for removing ammonia compounds from water along the water supply. In addition, it is advisable to install a thermostat in the control unit, supply the device with a pipeline for fresh water supply, connect it to the control unit, and make a device for removing ammonia compounds from the adsorbent material. The drawing shows the proposed device, a General view. The device for keeping water animals consists of a tank 1 for animals filled with water and a control unit 2 for treating water, which is connected to the lower part of the tank 1 by means of a discharge pipe 3 having a filter 4, a pump 5 and a valve b, the outlet part the control unit 2 is connected to the tank 1 of the return pipe 7 to return part of the water to any part of the tank 1. If necessary, the return pipe 7 can be equipped with a pump and a valve (not shown). The control unit 2 is also connected to a fresh water source (not shown) by means of a pipeline 8c with a pump 9. For treating water coming from the tank 1 through a branch pipe 3, the control unit 2 contains a thermostat 10, which regulates the temperature E l of the water and maintains its at the lowest level at which one animal can exist, a device 11 for aerating water, providing direct contact of water with air, devices 12 for removing ammonium compounds from water and device 13 for Removal of water-soluble organic compounds from water. In addition, the device has a source 14 for supplying an oxidizing agent, connected to the branch pipe 3 in front of the device 12 for removing ammonia compounds from the water through pipe 15c valve 16 and pump 17, and in the control unit 2 a device 18 for decomposing oxidizer residues - to convert the oxidizing agent into non-chemical substances for animals. To drain the water from the tank 1, it is equipped with a pipe 19 with a valve -20. . The oxidizing agent supplied from source 14 can be selected from compounds of hypologologic acids, for example, measures of hypochlorous compounds (hydrobromous or hypoiodous acids, hydrogen peroxide, azone, and mixtures of two or more of these substances. The most preferred compound of hypogologic acid is hypochlorite sodium, since this compound has a high oxidative capacity. The compounds formed by the oxidation of a ® and naturally occurring and organic compounds, as well as the decomposition product of sodium hypochlorite, are not Suitable for converting an oxidizing agent into substances non-toxic to aquatic animals are catalysts effective for decomposing the residue of an oxidizing agent, which can be chosen from natural zeolite, synthetic zeolite, aluminum aluminum silicate, aluminum silicate. magnesium silica, alumina, activated clay, acid clay, activated carbon derived from coconut husks or coal, and mixtures of two or more of the mat In terms of the efficiency of decomposition per unit volume, the most preferred catalyst is the above mentioned types of activated carbon, which are effective for all types of oxidizing agents. The removal of ammonia compounds from water can be carried out by contacting it with a mass of adsorbing material, which is selected from organic polymer ion exchange resins, inorganic ionic materials, 1 for example, natural zeolite, synthetic zeolite, alcuminium silicate, aluminum silicate, silica, silica, alumina, and anomalies. zirconium type ion exchange materials, such as zirconium phosphate, zirconium tungsten and zirconium molybdate, activated carbon, and mixtures of two or more of these ies materials These materials are highly effective for the removal of ammonium compounds even when used in relatively small amounts. Said adsorbent materials are particularly effective for removing ammonia compounds from seawater. If water is supplied to a device from rivers or an urban water-borne system, the adsorbing material may be an organic polymer ion-exchange resin, for example, a cation-exchange resin of a strongly acidic nature, such as cation-exchange resins of sulphonic acid and salt type, and a cationic-enamel resin of a slightly acidic character, for example, a cationic resin of carbonic acid and salt type. The ion exchange resin can be used in a mixture with the said adsorbent material. In this case, the adsorption material containing the cation exchange resin can remove a small quality of a certain type of ammonium compounds from the water, and the lmiar compounds can be removed using a reversible osmosis– or ion – uroHHoro membrane device. . The removal of water-soluble organic compounds from water can be carried out by contacting it with a mass of adsorbing material that facilitates the flow of water through it. This adsorbing material may be selected from natural or synthetic zeolites, activated silica, silica-alumina, bone char, acidic clay, activated clay, aluminum aluminosilicate, magnesium aluminosilicate, and mixtures of or more of the aforementioned materials. Hydrogen and organic matter can be removed from water and upon contact with aluminum hydroxide, which allows organic compounds to coagulate and precipitate with aluminum hydroxide, after which the resulting precipitate is removed from the water. The operation of the device is based on the following. When living aquatic animals are kept in water, the latter is contaminated with products of metabolism, the presence of which worsens the conditions of animal life and reduces their life. The proposed device allows continuous monitoring of the concentration in the form of ammonia compounds, water-soluble organic compounds, carbonic acid radical and molecular oxygen in order to maintain these parameters at this level. In this case, animals can be kept alive for a long time. period of time. In the device, animals are kept in tank 1 with a high density of planting corresponding to more than 200 kg / m, but not exceeding 700 kg (preferably 250-600 kg / m), and the temperature of the water is maintained at a low level with the help of a temperature controller 10, at which water animals may exist. The greater density of aquatic animals leads to the limitation of their water availability, and this limitation causes a low expenditure of energy of active metabolism of aquatic animals. Therefore, under these conditions, most of the energy of metabolism of aquatic animals is consumed in order to maintain their viability, which leads to a prolongation of animal life. When the device operates, water temperatures are adjusted so that when it contains, for example, adults of the red sea bream, it (the interval is 1-12 ° C, when it is kept; adults of carp are 3-20 C, while the content of adults is 10- 15 ° С, when the mollusk contains the sea ear, 5-14 ° С, and if the mollusk contains 3-12 C., when keeping adult animals, they consume molecular oxygen dissolved in it and release carbon dioxide, ammonia compounds. and water-soluble organic compounds, such as ammonia, Primary, secondary, and tertiary amine compounds, for example, urea, uric acid, creatine, creatinine, trimethylamine amioic acids, higher fatty acids, linids, and proteins. Aquatic animals cannot remain alive in water containing a certain amount of these compounds and a small amount of molecular Oxygen. Therefore, water coming from reservoir 1 through branch pipe 3 is fed to control unit 2, previously entering the agent from the source 14. Next, the water containing the yugia oxidizing agent comes in contact with the device 12 for removing ammonia compounds from the water, with the device 13 for removing water-soluble organic compounds from the water and with the device 18 for converting the oxidizing agent into non-toxic substances for fish, after which it enters into the device And for aeration, where the water through the pipeline 21 from the pump 22 serves by blowing or bubbling air. With this contact of water with air, it is enriched with molecular oxygen, and the carbon dioxide contained in the water passes into the air. The contact of water with air can be accomplished by spraying water in air. In the device, the concentration of ammonia compounds, water-soluble organic compounds and carbonic acid radical and water is regulated so that their level does not exceed 20, 150 and 1000 ppm, respectively, and the concentration of molecular oxygen dissolved in the surrounding water is adjusted so that was at least 3 parts ca. After water treatment with a thermostat, its temperature is adjusted so that it corresponds to the level required for this animal species, and through return pipe 7 it is fed back to reservoir 1g because it becomes its indicators suitable for further keeping animals. So, if sea water entering controlled block 2 contains 10 parts of sodium hypochlorite per million as an oxidizing agent, then when it contacts d 400 ml of natural zeolite with a particle size of 3 m, the amount of hypochlorite is only 3.1 parts per million i.e. decomposition of 69 wt.% sodium hypochlorite occurs. When used for the decomposition of activated carbon with dimensions of 3–3 mm, water contains only 0.6
