| Abstract: | Circulative Channel Flow Process (CCFP) was introduced in this paper due to its great advantages in nitrogen and phosphorus removal from urban sewage. Traditional activated sludge process and oxidation ditch process were integrated effectively in CCFP, with the combination of complete mixing and circulative flow in the process. Therefore, reactions in CCFP were optimized and stable operation cowld be achived, which were helpful to increase wastewater treatment efficiency and also improve system capacity for organic impact loading. Compared with traditional A2/O process, CCFP had advantages in energy saving, with about 30% decreased in energy consumption. Results of analysis further indicated that the cost on construction and equipments of CCFP was much lower. |
