Example Embodiment

[0033] Example 1

[0034] The Bacillus subtilis with the preservation number CICC10732 was added to the sterilized and cooled 0.9% normal saline. After shaking to dissolve, it was allowed to stand for 30min activation in the incubator, and then the mass ratio of 6:2:1 glucose, ammonium sulfate and Expanded culture in potassium phosphate medium for 15 days to obtain Bacillus subtilis culture solution; in the process of expanding culture, when the oxygen content in the bacterial solution is less than 2.5mg / L, it is necessary to add glucose with a mass ratio of 6: 2: 1 , Ammonium sulfate and potassium phosphate;

[0035] The Bacillus atrophicus with the preservation number CICC23590 was added to the sterilized and cooled 0.9% normal saline, shaken to dissolve and allowed to stand for 30 minutes in a thermostat for activation, and then in the mass ratio of 6: 2: 1 glucose, ammonium sulfate and Expanded culture in potassium phosphate medium for 15 days to obtain Bacillus atrophicus cul...

Abstract

The invention provides a strain composition for treating VOCs containing waste gas. The strain composition is prepared from bacillus subtilis, bacillus atrophaeus and virgibacillus pantothenticus. The invention further provides a method for treating the VOCs containing waste gas. The method comprises the following steps that the VOCs containing waste gas is subjected to biological treatment, and strains adopted during biological treatment comprise bacillus subtilis, bacillus atrophaeus and virgibacillus pantothenticus. Bacillus subtilis, bacillus atrophaeus and virgibacillus pantothenticus are used in cooperation for treating the VOCs containing waste gas, the treatment effect can be greatly improved, and the degradation efficiency reaches 95% or above.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment, in particular to a strain composition for treating waste gas containing VOCs and a method for treating waste gas containing VOCs. Background technique [0002] Volatile organic compounds, the English name is volatileorganiccompounds, abbreviated as VOCs. In my country, it refers to organic compounds with a saturated vapor pressure greater than 70Pa at normal temperature and a boiling point below 260°C at normal pressure, or a vapor pressure greater than or equal to 10Pa at 20°C. All organic compounds of corresponding volatility. The most common VOCs are benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate, etc. [0003] VOCs are atmospheric pollutants, which use the air as the medium of transmission, and have toxic effects on the human body through the respiratory system and skin. At present, the main methods of controlling VOCs are physical...
