A multi-stage odor scrubber comprising a first stage odor scrubber comprising a first contact chamber, a first sump for collecting liquids and a first recirculation pump. The multi-stage scrubber further comprises a second stage odor scrubber, the second stage odor scrubber comprising a venturi chamber with one or more venturi adjacent the first contact chamber, and a third contact chamber. The venturi chamber is positioned between the first and third contact chambers. A unitary housing contains the first and second stage odor scrubbers. The second stage odor scrubber further comprises a second sump for collecting liquids from the venturi chamber and the third contact chamber, and a second recirculation pump for re-circulating liquid. A method for removing contaminants from a gas stream comprises propelling a contaminated gas stream through the multi-stage odor scrubber.
