| Abstract: | Biodenitrification by immobilized microorganism using macroporous carrier prepared by the research group was studied.After one SBR period with influent of 5 min,aeration 2.5 h,precipitation 1h and discharge 30 min,COD of the effluent can satisfy Grade I of the drinking water standard when influent COD was 30~100 mg/L while influent NH4+-N ranged from 4.5~24.2 mg/L,the effluent NH4+-N kept at the range of 0.4~1.5 mg/L,with removal rate over 90%.Results indicated that removal rate of NH4+-N and COD would not ... |
