Embodiment 1

[0034] The Bacillus subtilis with the preservation number CICC10732 was added to sterilized and cooled 0.9% physiological saline, shaken and dissolved, and left to activate in an incubator for 30 minutes, and then the mass ratio was 6:2:1 of glucose, ammonium sulfate and Expand the cultivation in the medium of potassium phosphate for 15 days to obtain the Bacillus subtilis culture fluid; during the expansion cultivation process, when the oxygen content in the bacterial fluid is lower than 2.5mg / L, glucose with a mass ratio of 6:2:1 needs to be added , ammonium sulfate and potassium phosphate;

[0035] Add the Bacillus atrophaeus with the preservation number CICC23590 into sterilized and cooled 0.9% physiological saline, shake and dissolve, and place it in an incubator for 30 minutes to activate, and then in the mass ratio of 6:2:1 glucose, ammonium sulfate and Expand culture in the medium of potassium phosphate for 15 days to obtain the culture solution of Bacillus atrophaeus;...

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...
