Do you know the working principle of biological waste gas treatment

Microbial degradation (biological waste gas treatment) refers to the digestion and metabolism of pollutants in organic waste gas by microorganisms. A new technology to absorb organic waste gas as nutrients by using the growth and reproduction characteristics of microbial strains.

Biofilm is the core of biological treatment of organic waste gas. Its basic principle is to use microbial breeding technology to form a variety of special microbial strains through cultivation, domestication and enrichment, and then inoculate these microbial strains on the surface of porous fillers to form a biofilm layer. When the waste gas containing various volatile organic compounds flows through the packed tower, the pollutants in the waste gas are transferred to the biofilm due to diffusion; Under suitable environmental conditions, biofilm grows and reproduces through biochemical reaction with microbial enzymes, and organic components in waste gas are degraded into carbon dioxide, water and cell components as nutrients, thus achieving the purpose of purifying waste gas.

Biological waste gas treatment equipment is suitable for odor and waste gas treatment in urban sewage treatment plants, sewage pumping stations, sewage treatment plants (stations), petrochemical, pharmaceutical and chemical industries, food processing, spraying, printing, textile printing and dyeing, leather processing and other production industries.

Advantages of biological waste gas treatment equipment:

1. Simple equipment, low operation cost, low operation and maintenance cost and high safety performance.

Secondly, with the long-acting biological filler, microorganisms can grow by the nutrients in the washing liquid and the odor in the gas without additional nutrition. Biofilm has stable ecological conditions, large biomass per unit volume, strong biosorption and oxidation ability of microbial community, strong impact resistance, fast decomposition speed and high decomposition efficiency;

Third, the tower body adopts modular structure, which is convenient for on-site construction and installation;

4. Unique air distribution mode, uniform air distribution and high purification efficiency of 90%.

Five, low energy consumption, no secondary pollution transfer.

6. The longer the running time, the better and more stable the microorganism is to the waste gas.
