Abstract
FIELD: gas purification. SUBSTANCE: invention is dealing with removing impurities from effluent gases via purification on biofilter and may find use in petrochemical and chemical industries as well as at biological purification stations. Filter material of invention has on its surface fixed microorganisms and is preliminarily treated with aqueous solution containing 0.5-1.0 g/l of nonionic surfactant at 15- 25 C and atmospheric pressure for 0.5-1.0 h, whereupon effluent gases are saturated with water and passed through biofilter. Additional treatment of filter material allows achieving efficacious removal of water-soluble and difficultly soluble in water impurities from effluent gases, in particular, isoprene dimers and trimers, benzene, toluene, ethylbenzene, styrene and other aromatic hydrocarbons, some of them being only partially or not at all removable with the aid of known procedures. Degree of toluene removal attains 96%. EFFECT: increased purification degree. 2 tbl
