Problems solved by technology

However, since the fish tank is a small closed water body, and it is also an unstable dynamic water body, the input feed and the feces of the fish itself will increase the concentration of ammonia nitrogen, nitrite nitrogen, and total nitrogen in the water. keeps getting worse
In order to solve the "water" problem, there are some devices on the market that solve fish tank water through physical filtration, chemical filtration, etc., but they still need to be cleaned frequently, although some fish tanks are put in nitrifying bacteria, which reduces the amount of ammonia nitrogen and nitrite nitrogen. However, it is still impossible to remove nitrate nitrogen and total nitrogen. With the accumulation of nitrate nitrogen and total nitrogen, the pH of fish tank water quality gradually decreases, which affects the living habits and eating taste of fish. For this reason, current fish tanks are only used for raising As an ornamental fish, it is rare to use a family fish tank to raise edible fish

Embodiment 1

[0029] like Figure 1 to Figure 3 As shown, it is an aeration-driven water circulation and total nitrogen removal ecological fish tank provided in Embodiment 1 of the present invention, which includes an ultraviolet disinfection lamp tube 1, a biological enzyme charcoal filler purification box 2, a denitrification and denitrification filler purification box 3, Breeding tank 4 and two residue collection devices 5 . The biological enzyme charcoal filler purification box 2 and the denitrification and denitrification filler purification box 3 are respectively arranged on both sides of the culture tank 4 .

[0030] The ultraviolet sterilizing lamp tube 1 is used for sterilizing the water body. In this embodiment, the ultraviolet disinfection lamp tube 14 is placed at the bottom of the denitrification and denitrification purification box 3 .

[0031]Biological enzyme charcoal filler purification box 2 is filled with biological enzyme charcoal filler 6 and aeration device 16 . In ...

Embodiment 2

[0044] This embodiment is roughly the same as the No. 3 fish tank in Embodiment 1, and the difference is that the biological enzyme charcoal filler is prepared by the following method:

[0045] Add 30% modifier of the weight of the charcoal to the charcoal that has been vibrating, sieved and rounded with a particle diameter of 6-20 mm, in which 1% glucosamine and 3% glucosamine sulfate are in the A liquid of the modifier , and the balance is water. In liquid B, there are 8% peptone, 0.1% iron sulfate, 0.1% potassium dihydrogen phosphate, and the balance is water. The function of liquid B is mainly to provide nutrients for microorganisms. After the liquid A is mixed with the liquid B, the effect of changing the surface charge of the charcoal, promoting the immobilization of biological enzymes and promoting the reproduction of microorganisms has been multiplied. Turn the charcoal during the spraying process. The time for spraying and turning is 15 minutes. After standing still ...

Embodiment 3

[0052] This embodiment is roughly the same as the No. 3 fish tank in Embodiment 1, and the difference is that the biological enzyme charcoal filler is prepared by the following method:

[0053]Add 30% of the weight of the charcoal to the charcoal that has been vibrating, sieved and rounded with a particle diameter of 6-20mm, and add 30% of the weight of the charcoal as a modifier, wherein in the liquid A of the modifier, 1.5% of glucosamine hydrochloride and 1.2% of glucosamine sulfate %, the balance is water. In liquid B, there are 5% corn steep liquor, 4% peptone, 0.1% iron sulfate, 0.1% potassium dihydrogen phosphate, and the balance is water. The function of liquid B is mainly to provide nutrients for microorganisms. After the liquid A is mixed with the liquid B, the effect of changing the surface charge of the charcoal, promoting the immobilization of biological enzymes and promoting the reproduction of microorganisms has been multiplied. The process of spraying stirs th...

Abstract

The invention provides an ecological fish tank for driving water circulation and removing total nitrogen through aeration. The ecological fish tank comprises an ultraviolet disinfection lamp tube, a bio-enzyme charcoal packing purifying box, a denitrification nitrogen removal packing purifying box and a breeding tank. The ultraviolet disinfection lamp tube is arranged at the bottom of the denitrification nitrogen removal packing purifying box. The bio-enzyme charcoal packing purifying box is formed by bio-enzyme charcoal packing and an aeration device. The denitrification nitrogen removal packing purifying box is formed by denitrification nitrogen removal packing and an aeration device. A water outlet above the bio-enzyme charcoal packing purifying box and a water outlet above the denitrification nitrogen removal packing purifying box are lower the water face of a water body in the breeding tank. Under the effects of the aeration devices, the water body in the lower portion of the breeding tank enters the upper portion of the breeding tank through the bio-enzyme charcoal packing and the denitrification nitrogen removal packing from bottom to top. The ecological fish tank has the capacity of efficiently decomposing fish feces and purifying the water quality, and has the high adsorption capacity; the fish feces and feed left at the bottom of the facility are effectively removed, it is guaranteed that the quality of water in the breeding tank is clean, and water changing is not needed.

Description

technical field [0001] The invention relates to a fish tank, in particular to an aeration-driven water circulation and total nitrogen removal ecological fish tank and a method for raising edible fish using the same. Background technique [0002] Fish is rich in nutrition and delicious in food. However, due to water pollution and changes in farming methods, people generally lament that it is difficult to experience the delicacy of eating fish in the past. Simultaneously along with the raising of people's living standard, ornamental fish tank is used more and more in shopping malls, offices and families as a kind of decoration. However, since the fish tank is a small closed water body, and it is also an unstable dynamic water body, the input feed and the feces of the fish itself make the concentration of ammonia nitrogen, nitrite nitrogen, and total nitrogen in the water continuously increase, and the water quality keeps getting worse. In order to solve the "water" problem,...
