FIELD: process engineering.
SUBSTANCE: invention may be used for cleaning external air of plenum vent systems of administrative and residential buildings of dust, aerosols, vapors and gas admixtures. Proposed method comprises mixing air to be cleaned with cleaning water flow, separating flows of cleaned air and dirty water, cleaning dirty water of dust, subjecting clarified water to short-wave ultraviolet radiation, and using it as cleaning water for cleaning air bearing volatile organic compound.
EFFECT: irrevocable removal of volatile organic compound.
