| 摘 要： | 采用SBR工艺处理人工配水,考察了进水COD及氨氮浓度、C/N值、好氧时间对诱导无厌氧段生物强化除磷的影响.结果表明,当以醋酸钠为碳源、进水COD和氨氮分别为100和5mg/L、C/N值为20时,对在A/O运行方式下表现为厌氧释磷、好氧超量吸磷的SBR,逐渐缩短其厌氧时间且保持好氧时间为135 min后,好氧吸磷现象并不会消失,仅是吸磷量略有降低.该除磷现象的发生是系统微生物经过特定诱导的结果.

| Abstract: | The SBR process was used to treat artificial synthetic wastewater,and the effects of influent COD,ammonia nitrogen,C/N ratio and aerobic time on induction for enhanced biological phosphorus removal without anaerobic phase were investigated.The SBR with anaerobic phosphorus release and aerobic phosphorus uptake is operated in A/O mode.When the sodium acetate is used as carbon source,and the influent COD,ammonia nitrogen and C/N ratio are 100 mg/L,5 mg/L and 20 respectively,the aerobic phosphorus uptake does ... |
