Description

Technical Field

[0001] The utility model belongs to the technical field of biological fermentation tanks specially used for sewage treatment, and more specifically, particularly relates to a biological fermentation tank. Background Art

[0002] Biological fermentation tanks are widely used in aerobic fermentation processes such as antibiotics, amino acids, enzyme preparations, vitamins, organic acids, etc. In the chemical industry, they can be used for gas-liquid and gas-liquid-solid reaction processes. In environmental protection, they can be used for sewage treatment. The existing biological fermentation tanks for sewage treatment are mainly composed of tank bodies, stirring paddles, ventilation pipes and sensors. The tank body is mainly used to cultivate and ferment various bacteria. The stirring paddle is used to stir continuously during the fermentation process. The ventilation pipe is used to discharge excess gas generated during the fermentation process. The sensor on the top plate of the tank body is used to display various numerical parameters to provide data reference for sewage treatment.

[0003] The existing application number is: CN201320592344.7. The utility model discloses a biological fermentation tank, which comprises a tank body (1) and a tank cover (2) arranged on the upper part of the tank body (1), wherein a pressure gauge socket (3), a temperature gauge socket (4) and a feed port (5) are respectively arranged on the top of the tank cover (2), a rotating shaft (7) is installed at the center position of the top of the tank cover (2), a motor (6) is installed on the upper part of the rotating shaft (7), a stirring blade (8) is installed at the bottom of the rotating shaft (7), a discharge port (10) is arranged at the bottom of the tank body (1), and a stirring blade (9) is installed on the lower side wall of the tank body (1). An air inlet pipe (11) is provided which extends into the tank body (1), an air compressor (15) is installed at the other end of the air inlet pipe (11), a filter (12) with a filter screen (13) is also provided on the air inlet pipe (11) outside the tank body (1), a liquid level gauge (14) is connected to the outside of the filter (12), an air outlet pipe (16) is also provided on the top of the tank cover (2), and an exhaust gas processor (17) with a filter screen (18) is provided on the top of the air outlet pipe (16); the above structure is simple in structure, easy to use, safe and reliable, and can eliminate harmful gases in the biological fermentation process.

[0004] Based on the above, when using a special biological fermentation tank for sewage treatment, it is sometimes necessary to add desulfurization and denitrification bacteria. The desulfurization and denitrification bacteria can quickly degrade harmful substances such as ammonia nitrogen, nitrite, hydrogen sulfide, methane, heavy metal ions, etc. in sewage, and can adjust the pH value of sewage, stabilize water quality, and inhibit the growth and reproduction of harmful algae. This desulfurization and denitrification bacteria is usually processed into a sphere with a diameter of two to five centimeters through a special granulation process. Each cubic meter of sewage requires about 200 grams of desulfurization and denitrification bacteria. When adding to the biological fermentation tank, in order for the desulfurization and denitrification bacteria to be fully mixed with the sewage, it is necessary to add and stir at the same time. However, the proportion of desulfurization and denitrification bacteria that need to be added to the sewage is low and the volume of the desulfurization and denitrification bacteria is small, while the volume of the biological fermentation tank is large. Therefore, when the corresponding proportion of desulfurization and denitrification bacteria are all added at one time, the desulfurization and denitrification bacteria added to the sewage are easy to adhere to each other, which slows down the speed at which the desulfurization and denitrification bacteria dissolve in the sewage and affects the working efficiency of sewage treatment.
