Description

Technical Field

[0002] Aerobic denitrifying bacteria are a type of denitrifying bacteria that use the action of aerobic denitrifying enzymes to denitrify organic matter under aerobic conditions. They use the oxygen in nitric acid to oxidize organic matter and obtain the energy needed for their own life activities. They are widely used in sewage treatment.

[0003] Denitrifying bacteria are widely distributed in soil, manure and sewage. Denitrifying bacteria can convert nitrate nitrogen into nitrogen gas or nitrous oxide instead of ammonia nitrogen. Aerobic denitrifying bacteria mainly exist in Pseudomonas, Alcaligenes, Paracoccus and Bacillus, and can be cultured and propagated by adding nutrient solution to the culture. Put the raw materials such as culture and nutrient solution into the box, keep the materials in the required temperature range, and let air into the box, so that the denitrifying bacteria in the culture can be cultured and propagated.

[0004] The inventors of the present application have discovered that in the existing aerobic denitrifying bacteria culture device, when air is introduced into the box, it is unevenly distributed in the box, and cannot quickly contact and mix with the culture body and be integrated into the culture body, resulting in low oxygen supply efficiency; and the box used for culture is generally large, and the raw materials of the material body have a certain viscosity, so that the material body in the box is not sufficiently stirred, resulting in uneven heating of the material body, which affects the culture efficiency and effect of the denitrifying bacteria.
