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.
Treatment of domestic sewage by PAC (powdered activated carbon) -SBR process was investigated. Results showed that removal rate of TN and TP and the activated sludge settling characteristics were improved by addition of powdered activated carbon. In the case that optimal dosage of PAC, 400 mg/L, removal rate of COD,TN and TP were 94.90, 67.70% and 96.55% respectively, and SVI of activated sludge was 45.2, better than those of SBR process. Mechanism of enhancement in PAC SBR process was concluded. PAC-SBR system was operated for one month, the effluent met the Grade 1 Class B of "Discharge standard of pollutants for municipal wastewater treatment plant" (GB18918-2002). PAC-SBR process was steady and efficient.
