Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
A biotrickling filter on pilot-scale was experimented to treat gas with low concentrations of styrene to explore the major controlling factors and purification mechanism. The gas flow was 250-1200 m3/h; the concentration of styrene was 20-120 mg/m3; the retention time was 0.8-4.3s. It was shown that the purification process is dual control process dominated by mass transfer and biodegradation; the mass transfer was controlled by the gas film, not liquid film between the biofilm and gas. The removal efficiency of styrene decreased while the load increased; the removal rate increased while the concentration and the gas flow increased. In the range of 80-100 mg/m3, removal rate tend to stable. Also, the treatment was impacted by other factors such as temperature, nourishment, spray liquid, characteristics of stuffing.
