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.
Two kinds of biological activated carbon filter (BACF), which were immobilized by high dehydrogenase activity (DHA) bacteria isolated from river water (H-BACF) and dominant bacteria from activated sludge (S-BACF), were set up to treat the river water. Results showed that dissolved-oxygen (DO) decrease of the filtrated water (compared with the influent water), bacterium number and DHA of carbon bed in H-BACF were more than that in S-BACF, and both increased with operation time. Scanning electron microscopy (SEM) indicated there was a better effect of immobilization in H-BACF compared to S-BACF. When the influent water was chemical oxygen demand (CODMn) 3.51-4.32 mg/L, total organic carbon (TOC) 4.705-12.700 mg/L, total nitrogen (TN) 4.705-12.700 mg/L, and UV254 0.066-0.114, the removal rates of H-BACF were 65.4%, 62.5%, 35.3% and 89.5%, higher than that of S-BACF (51.2%, 54.0% , 18.9% and 87.1%). Thus, the immobilization of high DHA bacteria from object source-water could improve likely bio film activity and treatment efficiency of BACF very well.
