| Abstract: | Pilot scale study of cyclic activated sludge technology (CAST) for urban wastewater treatment plant was undertaken,and results indicated that under operation period of 4.5h,precipitation ratio of 35%,sludge age of 15d,DO 31mg/L,best conditions of bacteria culture and domestication were obtained,with sludge concentration up to 2,000mg/L,stability of biological phase,efficient treatment and various effluent indicators satisfactory to criteria. |
| Keywords: | wastewater treatment cyclic activated sludge technology (CAST) pilot scale study |
