生物脱氮技术的研究

废水生物脱氮已经成为水污染控制的一个重要研究方向.传统的生物脱氮采用的是硝化、反硝化工艺,但存在着很多问题.对短程硝化反硝化、同时硝化反硝化及厌氧氨氧化等生物脱氮新技术的研究和开发进展进行了简单的综述和讨论,并指出了这些新技术的特点和研究开发应用的前景.

Study of Biological Nitrogen Removal

The study of nitrogen removal from waste water has been animportant direction of waste water control.The traditional methods of biological nitrogen removal adopted initrification and nitrification technology,but there are lots problems.The progresses of biological nitrogen removal,such as the investigation on shortcut nitrification-denitrification,simultaneous nitrification denitrification(SND)as well as anaero bic ammonium oxidation,are simply reviewed and discussed in this paper.The advantages of these new technologies arebcompared with the traditional nitrifcation and denitrification technology,and it can be concluded that the new technologies are promising for further investigation and applications.
