【摘要】：氮磷引起的环境问题已引起世界关注,低成本减少水体氮磷污染是生物处理工艺面临的挑战.亚硝化-反硝化除磷工艺具有节约碳源和能源、节省空间及占地、提高水处理设备利用率、减少污泥产量等优势,但关于聚磷菌(PAOs)的认知缺乏深入了解,且目前尚未见氨氮亚硝化-反亚硝酸除磷整体工艺的稳定运行报道.关于PAOs的分类,不同研究者有不同见解,而短程反硝化除磷机理的研究结果主要是利用厌氧释磷储能,能量用以供给缺氧条件下利用亚硝酸盐为电子受体进行反硝化过量吸磷.短程反硝化除磷的脱氮除磷效果会受到温度、p H、碳源种类及ρ(C)/ρ(P)等诸多因素的影响,调节控制合理的反应条件有助于实现稳定高效的污废水处理效果.总结分析短程反硝化除磷的相关研究报道,对指导污废水生物脱氮除磷并克服其存在的不利因素很有必要.
[Abstract]:The environmental problems caused by nitrogen and phosphorus have attracted the attention of the world. Reducing the pollution of nitrogen and phosphorus in water at low cost is the challenge of biological treatment process. Nitrification-denitrifying phosphorus removal process has the advantages of saving carbon and energy, saving space and occupation, improving the utilization of water treatment equipment, reducing sludge yield, etc. The stable operation of the whole process of ammonia nitrogen nitrification and denitrite phosphorus removal has not been reported. Regarding the classification of PAOs, different researchers have different opinions, and the results of the study on the mechanism of denitrification phosphorus removal are mainly using anaerobic phosphorus release storage energy to provide energy for denitrification excessive phosphorus absorption using nitrite as electron acceptor under anoxic condition. The effect of denitrification and phosphorus removal by short-cut denitrification will be affected by many factors, such as temperature, carbon source and 蟻 Con / 蟻 P, etc. Adjusting the reasonable reaction conditions is helpful to realize stable and efficient wastewater treatment. It is necessary to summarize and analyze the related research reports of short-cut denitrification and phosphorus removal for guiding biological denitrification and phosphorus removal of wastewater and overcoming its unfavorable factors.
