摘　　要：生物脱氮技术是一种经济、有效的方法,而膜生物反应器(MBR)中同步硝化反硝化(SND)与传统生物脱氮技术相比具有很大的优势。对MBR中SND现象的原理进行了分析,并探讨了MBR中SND脱氮效率的影响因素,包括曝气强度、p H值、碳氮比和污泥停留时间等;同时,针对MBR中膜污染问题进行了总结。最后,提出SND-MBR目前在应用中存在溶解氧控制和膜污染控制的问题,指出了其进一步研究的目标和方向。Biological nitrogen removal process is an economic and effective method, and the simul- taneous nitrification and denitrification （SND） in membrane bioreactor （MBR） has great advantages over traditional biological nitrogen removal process. The mechanism of SND in membrane bioreactor was ana- lyzed, and some influencing factors of SND were discussed, including aeration intensity, pH, C/N ratio and sludge retention time. Recent studies on the membrane fouling in membrane bioreactor were re- viewed. The problems about dissolved oxygen control and membrane fouling control in practical applica- tion were put forward, and the further research goals and direction were pointed out.
