| Abstract: | The continuous step feed biological nitrogen and phosphate removal (CSFBNR) process can make good use of influent COD as the carbon source required in denitrification. It can achieve high removal efficiencies of nitrogen and phosphate when treating municipal or industrial wastewater with low C/N ratio. In this review, the operational principle and characteristics of CSFBNR are discussed and significant factors influencing operation performance are highlighted, including the step numbers, influent flow distribution, anaerobic zone to aerobic zone volume distribution ratio, dissolved oxygen, sludge return ratio and influent characteristics. Based on the state of the art and application examples, process control techniques and application prospects are discussed and areas in which further research is urgently required are identified. Establishing design criteria and developing relevant process control systems are two critical points for promoting and broadening the application of CSFBNR in China. |
