Abstract

The invention relates to a treatment method of VOC (volatile organic compounds) waste gas. The method includes the steps of: selecting compound microorganisms; employing a domestication nutrient solution to perform domestication operation on the compound microorganisms; conducting centrifugal resuspension operation to improve the concentration of the microorganisms; soaking activated carbon particles in the compound microorganism liquid to obtain microbial activated carbon filler; selecting skeleton filler, and mixing the skeleton filler with the microbial activated carbon filler to obtain a biocarrier filler; filling a bio-trickling filter with the biocarrier filler; employing a spray solution to perform spray operation to the top of the biocarrier filler, letting the spray solution flow through the biocarrier filler and drip to the bottom of the bio-trickling filter under the gravity of the spray solution itself; introducing VOC waste gas to the bottom of the biocarrier filler and making the VOC waste gas permeate the biocarrier filler; and collecting the spray solution at the bottom of the bio-trickling filter, and discharging the spray solution, thus enhancing the treatment efficiency of VOC waste gas.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a method for treating VOC waste gas. Background technique [0002] VOC is the English abbreviation of volatile organic compounds (volatile organic compounds). The definition in the sense of environmental protection refers to a type of active volatile organic compounds, that is, the type of volatile organic compounds that will cause harm. VOC waste gas usually refers to the waste gas formed in the industrial production process. VOC waste gas is a kind of active volatile organic compound, an organic compound that can participate in atmospheric photochemical reactions. In addition, VOC waste gas has a huge impact on human health. When the environment is When the VOC reaches a certain concentration, people will feel headache, nausea, vomiting, fatigue, etc. in a short time. as a result of. [0003] Biological treatment of VOC exhaust gas is the most cost-effective method....
