Two Way Directional Biological Trickling Air Biofilter system

摘要

The present invention is a volatile organic compound (Volatile Organic Compounds, such as benzene, toluene, xylene, ethylbenzene, phenol, etc. generated in various businesses, such as petrochemical plants, coating plants, food processing plants, waste intermediate treatment plant, manure / sewage treatment plant VOCs) and methods and apparatus for the biological removal of sulfur-based and nitrogenous odorous substances.;The present invention is to fill a filter made of a ceramic or plastic ring with microorganisms attached to the housing and to purify the odor waste gas by passing the waste gas containing VOCs and malodorous substances through the filter inside the housing, the gas is It is a technology to effectively remove VOCs and odorous substances in waste gas by keeping the concentration / distribution of microorganisms adhered to the filler surface and the microbial biofilm on the entire reactor by allowing them to be selectively alternately introduced from both directions. .
