【摘要】 总结了SBR脱氮工艺中的同步硝化/反硝化、亚硝化脱氮现象,讨论了影响SBR除磷的碳源、聚磷菌与非聚磷菌竞争、pH值、好氧曝气、污泥龄、水力停留时间等因素,并对SBR工艺中脱氮除磷的相互影响进行了探讨;最后,给出了可以同时脱氮除磷的一种SBR的运行方式。更多还原

【Abstract】 The phenomena of simultaneous nitrification and denitrification,and n itrite denitrification in SBR was summarized.The factors such as c arbon source,competition of PAOs an d non-PAOs,pH,aeration,sludge age and hydraulic residence time whi ch affect phosphorus removal of SBR w ere discussed.The interaction of ni -trogen and phosphorus removal was also approached.Finally,an operatio n way of SBR to simultaneously remove nitrogen and phosphorus was suggested.更多还原
