With the rapid development of industry and urbanization, malodorous gas is a common pollutant in industrial production, urban life and natural environment. Its composition is complex and the problem is increasingly prominent, which has a serious impact on human health and environment. The traditional physical and chemical deodorization methods have some problems, such as unstable treatment effect and secondary pollution. Biological deodorization technology has become an important means to solve the odor gas pollution, and has been widely used.
The main components of biological deodorant are lactic acid bacteria, yeast, photosynthetic bacteria, fermented filamentous bacteria and other environmental beneficial bacteria. The microorganisms and their metabolites in the biological deodorant can quickly capture and decompose the odor molecules in the odor gas, reduce NH3H2S and other volatile odors containing sulfur and nitrogen in the odor environment; secondly, the flora can produce an acidic environmental condition in the process of growth and metabolism, inhibit the growth and reproduction of some corrupt microorganisms, and reduce the production of odor from the source. The microorganisms in the biological deodorant can form a good microbial ecosystem in the filter or filter. The deodorant bacteria can grow and reproduce the harmful substances in the odor into harmless carbon dioxide and water and microbial cell components.
The Principle of a Biological Deodorant Tower
Biological deodorant tower is a process of transforming the harmful components in the malodorous gas into harmless substances by using the metabolic activities of microorganisms. The basic principles are provided as follows:
1. Microbial adsorption: the organic pollutants in the malodorous gas are adsorbed by the microorganisms on the biofilm.
2. Microbial degradation: microorganisms use organic pollutants as carbon sources and energy sources, and decompose them into carbon dioxide, water, nitrate, sulfate and other harmless substances through the action of enzymes.
3. Gas diffusion: When the odorous gas passes through the biofilm in the biological deodorization tower, the harmful components are removed, and the purified gas is discharged from the top of the tower.
Application Effect of Biological Deodorant
1. Dedeodorization effect: biological deodorant can effectively remove the harmful components in the odor gas, and the deodorization effect is significant.
2. Environmental protection: no secondary pollution, environmentally friendly.
3. Economy: Biological deodorant technology has low operating cost and has good economic benefits.
4. Sustainability: The biological deodorization technology is sustainable and can operate stably for a long time.
Biological deodorization technology is an efficient and environmentally friendly odor gas treatment method, and its application effect is remarkable. Solve the problem of odorous gas pollution by the use of biological deodorant.
