Abstract
Disclosed is a biofilter system for removing volatile organic compounds, generated from various industrial facilities, such as petrochemical plants, refining plants and paint plants, and environmental facilities including sewage treatment plants. The biofilter system comprises a volatile organic compound (VOC) load equilizing portion, a VOC-containing contaminated air transferring portion, a biofiltering portion, and a storing portion for adjusting pH and nutrients in the biofiltering portion. By using such system, an offensive odor and VOC evolved from various industrial facilities and environmental facilities can be efficiently controlled. In addition, even in production processes and storage facilities at which high VOC concentration regulating materials are discontinuously discharged, VOC can be effectively removed.
