Marine product culture vat

Technical Field

The utility model relates to a breed jar, especially a marine product breed jar.

Background

The fishes and the aquatic animals can survive for a long time in the culture tank and must make the seawater or the fresh water in the tank reach or approach the technical index of the water quality of the natural seawater or the fresh water all the time. Of fish and aquatic animalsThe metabolic end products are generally discharged in the state of ammonia, which is dissolved in water in which the following chemical equilibrium exists: in the course of equilibration, non-ionic ammonia (NH)₃) And ionic ammonium (NH)₄ ⁺) The content is determined by pH value, pH value is less than 7, and almost all ammonium ions (NH)₄ ⁺) At pH values above 11, almost all ammonia (NH) is present₃) Are present. In addition, depending on the temperature of water, the ratio of nonionic ammonia increases as the water temperature increases, and ammonium ion (NH)₄ ⁺) At a certain content, the higher the water temperature or pH value, the nonionic ammonia (NH)₃) The greater the concentration, the more ammonia and ammonium ions can be converted in water, but their effect on seafood is different, non-ionic ammonia is harmful to fish, ammonium ions are harmless, and the sum of ammonia and ammonium ions in water is called the ammonium nitrogen value.

The fish and the aquatic animals respire and metabolize in water to generate carbon dioxide, and the carbon dioxide exists in the water in the form of carbonic acid, carbonate and bicarbonate, the more carbon dioxide is released in the culture tank, the stronger the acidity of the water is, and the higher the content of bicarbonate in the water in the culture tank is, the stronger the alkalinity of the water is, and the above reasons affect the pH value of the water.

Marine products are transported in long distance by car, and the advanced transporting method at home and abroad is that the car is equipped with generator set or inverter as power source, the refrigerator set is supplied to normal operation to reduce water temp. in the fish tank, then the air pump or oxygen bottle is used to oxygenate the fish tank, and the pH value and NH are regulated by manual chemical method₄ ⁺The value is large and small, so that the fish can survive in a dormant state at 6-10 ℃. The seawater ornamental fish tank and the restaurant culture fish tank also adopt a refrigerating unit to adjust the water temperature, and are different from the transportation fish tank in that a filtering system is added, such as filtering cotton wool, coral reefs and active carbon, and an air pump is added to oxygenate the fish tank. A protein separator is added in each high-grade fish tank to perform differentiation and separation on the protein in water. For the pH value and NH of water in the fish tank₄ ⁺The value is regulated by changing water and chemical method.

However, the prior art marine product transporting and cultivating tank has the following problems: the fish and aquatic animals are metabolized in the culture tank and decomposed into compounds containing nitrogen. With nitrogen predominantly as inorganic salts containing nitrogenForms, e.g. ammonium nitrogen Number (NH)₄ ⁺) Nitrite Nitrogen (NO)₂ ^-) And nitrate Nitrogen (NO)₃ ^-) Is easy to be absorbed and utilized by plants in a pond or sea, but does not have plants in the culture tank, so the nitrogen-containing organic matters are not easy to decompose and are mostly attached to the water bottom.
