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.
Vermifilter was founded on the basis of conventional biofilter, which introduced earthworms into the filter. In this study, the performance of vermifilter treating municipal wastewater under low temperature was investigated. Results showed that in the winter, the vermifilter could still perform well when the hydraulic loading was around 5.0 m3/m2-d. When the COD and NH3-N concentration of the influent was below 450 mg/L and 40 mg/L, respectively, COD could be reduced to less than 75 mg/L and ammonia nitrogen less than 20 mg/L. Water quality of the effluent could meet the second standard of Chinese Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).
