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.
Coking wastewater was treated by process of biological filter(BF) and bio-fluidized bed (BFB) with a special kind of carrier. The pretreated wastewater contained much more phenolic compounds with about 1460 mg/L of COD and 360 mg/L of NH+4-N. The wastewater treatment effect of this process was examined during biofilm colonization and operates formally. During biofilm colonization period, the treatment effect was greatly effected by biofilm colonization time. Since operates formally, the treatment effect was effected by HRT, reflux ratio, pH and aeration rate. The bio-fluidized bed system could achieve average removal efficiencies of 87.6% and 97.5% for COD and NH+4-N respectively at optimal operation condition, and NH+4-N in the effluent could meet the first level of National Discharge Standard.
