FIELD: chemistry.

SUBSTANCE: apparatus has a housing partially filled with a liquid and having an inlet pipe for contaminated air and an outlet pipe for clean air, and a cover. The cover has on its inner side a channel with an opening. The housing is divided by a partition wall into a working chamber fitted with a spraying device made in form of a drum having threads with a lyophilic surface attached to its surface, and a settling chamber. An air supply source is mounted at the inlet of the working chamber. A preliminary filter is mounted in the opening of the channel. A biofilter is mounted in front of the outlet pipe of clean air in the top part of the settling chamber. The liquid used is a nutrient solution for microorganisms of the biofilter, and the inner surface of the cover in the area of washing contaminated air as it passes between the cover and the drum lies equidistant from the surface of the drum.

EFFECT: high efficiency and quality of treatment owing to removal of contaminant organic compounds, pathogenic microorganisms, odours and dust from the air.
