Biological desulfurization technology is a method that utilizes microorganisms or biological enzymes to reduce the emission of sulfur dioxide (SO2) generated in industrial processes such as coal combustion. It has some advantages and disadvantages as follows:
Environmentally friendly: Compared to traditional chemical desulfurization methods, biological desulfurization technology is more environmentally friendly. It utilizes enzymes produced during microbial metabolism to catalyze the conversion of SO2, reducing the use of chemical agents and the generation of chemical waste.
Low energy consumption: Compared to other desulfurization methods, biological desulfurization technology has lower energy consumption. Microorganisms can grow and reproduce on their own under suitable environmental conditions, simply by providing appropriate culture media, temperature, pH, and other conditions. Compared to traditional desulfurization methods, the energy consumption is much lower.
Widely used: Biological desulfurization technology can be applied to various scale industrial facilities, including coal-fired power plants, steel plants, refineries, etc. It can flexibly adjust and adapt to different process conditions and exhaust gas components.
Cost reduction: Due to the use of naturally occurring microorganisms or enzymes instead of expensive chemical agents, biological desulfurization technology can reduce desulfurization costs to a certain extent.
Strict operating conditions: Biological desulfurization technology has strict requirements for the growth environment of microorganisms, including temperature, pH value, nutrients, etc. This requires precise control of the operating process to ensure that microorganisms can grow and function normally.
Relatively low treatment efficiency: Compared to traditional chemical desulfurization methods, the treatment efficiency of biological desulfurization technology may be relatively low. The speed of microbial metabolism is relatively slow, requiring a certain amount of time to achieve desulfurization effect, therefore requiring longer processing time.
Operational complexity: The operation of biological desulfurization technology is relatively complex, requiring professional personnel to monitor and manage the growth status of microorganisms to ensure the stable operation of the desulfurization system.
微生物适应性问题：在实际应用中，微生物可能会受到废气中其他成分的影响，如氧气含量、氮氧
Microbial adaptability issue: In practical applications, microorganisms may be affected by other components in the exhaust gas, such as oxygen content and nitrogen oxygen
