Anaerobic fermentation tank is a type of fermentation tank that eliminates oxygen and prevents oxygen from entering or not being supplied. The working principle of anaerobic fermentation tanks is to eliminate oxygen from the air through certain devices to achieve an anaerobic environment and promote the normal growth and reproduction of microorganisms. The system consists of two parts: an intake pipe and an exhaust pipe, where the gas introduced into the exhaust passage is called inert gas or reducing gas.
Anaerobic fermentation tanks are widely used to simulate the natural process of biogas fermentation, converting organic waste into renewable energy - biogas. In addition, the device is also applied in research fields such as anaerobic microbiology, bioengineering, and environmental science, which helps to gain a deeper understanding of the metabolic mechanisms and fermentation processes of anaerobic microorganisms. In the field of wastewater treatment, anaerobic fermentation tanks convert organic matter in wastewater into biogas through anaerobic fermentation, achieving harmless treatment of wastewater. Meanwhile, the device can also be used for the production of biofuels, such as converting waste into biogas through anaerobic fermentation technology for clean energy use.
The advantages of anaerobic fermentation tanks include adaptability to solid organic waste from various sources, low operating costs, increased capacity, low or no water demand, water resource conservation, low production of biogas slurry, low moisture content of waste residue, low subsequent treatment costs, the ability to produce biogas as a clean energy source, and reduced emissions of biogas. However, anaerobic fermentation tanks also have some drawbacks, such as the inability to achieve reduced sulfur compounds in surface water discharge quality without post-treatment, the need for appropriate solutions in terms of corrosion, odor, and safety, longer start-up cycles, and the need for an appropriate temperature range (15 ° C to 35 ° C)
Overall, anaerobic fermentation tanks are important industrial equipment with broad application prospects and various advantages. However, it is also necessary to pay attention to its drawbacks during use and take corresponding measures to solve them.
