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.
The biological purification device that combined the aeration-ship technology and biological contact oxidation was applied to the eutrophic river water treatment of Dongfeng channel in Zhengzhou city, Henan province. The effects of dissolved oxygen (DO) and hydraulic loading on the combined packing performance had been studied in previous paper. In this paper, Factors of reaction pH value and temperature were optimized using single factor test to find out the preferable treatment effect. Results showed the removal rates of CODcr, BOD5, NH3-H and TP were better when the operating pH value was 7.1~8.5 and the reaction temperature was 20°C~27°C.
