The present invention provides a scrubber comprising: a suction portion for forcibly removing harmful air from a contaminated area a first chamber into which harmful air flows through the suction portion, the lower portion of the first chamber being filled with a first cleaning liquid that is mixed with photosynthetic microorganisms at a preset ratio, and multiple first barriers being installed in the upper portion of the interior of the first chamber in parallel with one another at a predetermined interval such that the lower ends of the first barriers are spaced from the surface of the first cleaning liquid a second chamber into which the harmful air flows through the first chamber, the lower portion of the second chamber being filled with a second cleaning liquid that is mixed with Bacillus at a preset ratio, and multiple second barriers being installed in the upper portion of the interior of the second chamber in parallel with one another at a predetermined interval such that the lower ends of the second barriers are spaced from the surface of the second cleaning liquid a third chamber for emitting ultraviolet rays to the harmful air that flows in through the second chamber and a discharge portion for supplying air from the third chamber to the contaminated area. According to the present invention configured as above, the following advantageous effect can be predicted: harmful air generated from a contaminating facility, such as a stable, is purified and resupplied such that not only can livestock be kept stably, but stress applied to the livestock can also be minimized.La présente invention concerne un épurateur comprenant : une partie daspiration pour éliminer de manière forcée de lair nocif dune zone contaminée une première chambre dans laquelle lair nocif sécoule à travers la partie daspiration, la partie inférieure de la première chambre étant remplie dun premier liquide de nettoyage qui est mélangé à des micro-organismes photosynthétiques selon un taux pré
