Technical Field

The utility model relates to a filtration system, in particular to a biochemical reaction tank for filtering in aquaculture.

Background

The water quality in the circulating aquaculture is one of the important factors influencing the survival rate and the yield of the aquaculture, the content of ammonia nitrogen and nitrite in the water is increased due to the nitrification of excrement and residual baits generated by the aquaculture, and the nitrite can cause biological poisoning and death. Referring to the attached figure 1, in the denitrification process, nitrification is performed by nitrifying bacteria, ammonia nitrogen in water is converted into nitrite and nitrate through nitrification, then denitrification is performed by denitrifying bacteria, the nitrate is reduced to release nitrogen (N2) or nitrous oxide (N2O), the nitrifying bacteria belong to aerobic bacteria, the denitrifying bacteria belong to anaerobic bacteria, and the nitrifying bacteria and the anaerobic bacteria are difficult to coexist.

Publication No. CN108430216A, title of the invention, "denitrifying device and aquatic organism feeding system", discloses the following: an aquatic organism feeding system for feeding aquatic organisms in a closed circulation system, comprising: a rearing tank which stores rearing water for rearing aquatic organisms, a nitrification device, a denitrification device, and a pump; a nitrification device having a nitrification tank and a first filter medium stored in the nitrification tank, the nitrification device oxidizing ammonium nitrogen in the feed water by nitrifying bacteria fixed to the first filter medium; a denitrification device having a denitrification tank, a second filter medium accommodated in the denitrification tank, and an intermittent water discharge unit for intermittently performing an oxygen inhalation operation of discharging the feeding water stored in the denitrification tank to the feeding water tank to expose the second filter medium, wherein nitrate nitrogen in the feeding water is reduced by denitrifying bacteria immobilized on the second filter medium under aerobic conditions; pumping the feeding water stored in the feeding water tank by a pump and injecting the feeding water into the nitrification tank and the denitrification tank.

The invention provides a nitrification tank and a denitrification tank for nitrifying bacteria and denitrifying bacteria respectively, and then supplies feeding water to the feeding water tank, which can greatly increase feeding space and feeding cost.

Disclosure of Invention

In view of the technical problem that exists among the background art, the utility model aims at providing a biochemical reaction pond, reduces water treatment cost and equipment space.

In order to solve the technical problem, the utility model discloses a following technical scheme: the biochemical reaction tank is characterized in that: it comprises a biochemical pool, wherein the biochemical pool is provided with a water inlet and a water outlet, and the biochemical pool is internally provided with a water inlet and a water outlet

The surface of the medium for the propagation of nitrobacteria and denitrifying bacteria is provided with a plurality of small holes for providing attachment spaces for organisms, the inner walls of the small holes are rough, and one end of each small hole is closed;

and an aeration member.

The utility model discloses a medium provides the attachment space for nitrobacteria and denitrifying bacteria, and the aperture one end that the medium was densely covered is closed, makes denitrifying bacteria attach the position and gos deep into inside the aperture, and nitrobacteria then attaches to the aperture entrance, and aperture entry oxygen is many, and easily nitrobacteria breeds, and the aperture is deep supplies with for a short time, and is consumed by nitrobacteria, then easily denitrifying bacteria breeds, and in addition, the coarse easily interior membrane of hanging of pore wall, breed, therefore nitrobacteria and denitrifying bacteria can coexist, breed fast. The aeration part provides sufficient oxygen for the biochemical pool, provides living environment for nitrifying bacteria, accelerates nitrification, and can promote water in the biochemical pool to flow, the sewage and the flora carry out denitrification reaction, and the purified water is discharged from the water outlet.

Preferably, the medium is filled in a filter bag and suspended in a biochemical pool; the medium quantity is large, the filter bag is through, the effect of being beneficial to being suspended in the biochemical pool is good, so the medium can be completely immersed in water, and the bubbles generated by aeration can fully act on the medium to accelerate the nitrification.

Preferably, the medium is a rattan-pot shell; the barnacle shells are wastes of barnacles, belong to natural minerals, are rich in resource quantity, firm in structure, large in surface area, multiple in holes, rough in surface, good in biological adhesiveness and easy for formation of a mycoderm; not only has low cost, but also has excellent effect.
