| 摘要 |
A decontamination system and method for the decontamination of a contaminated gas. The contaminated gas is characterized by a gas phase and at least one contaminant. The contaminated gas is removed from its source and is introduced into a loop through which a bio-agent is circulated. The bio-agent includes a microorganism (e.g. bacterium) effective for the biodegradation of the contaminant. The bio-agent may also include a liquid carrier. The loop may include absorption column, separator and bioreactor positioned in the loop. An oxidation means can be utilized to oxidize metals in the contaminated gas. Alternatively, the bio-agent can be replaced by a liquid which circulates through the bioreactor and which is effective for absorption of the contaminant. In other embodiments, the loop can be replaced by a conduit in a form or arrangement other than a loop.
