摘要
"氮"的脱除是污水处理中的重点和难点,作为一种新型的生物脱氮技术,好氧反硝化技术具备传统生物脱氮技术缺乏的工艺用时短、占地面积小、硝化反硝化能同时发生等优点。在调研国内外研究现状的基础上,对好氧反硝化细菌的筛选方法进行了分析,对影响其脱氮效率的氮源、碳源、溶解氧、p H、温度、C/N等因素进行了总结,对好氧反硝化技术存在的问题进行了归纳,并在文献查阅的基础上,指明了好氧反硝化技术未来的发展方向。
It is hard to remove the nitrogen from the waste water. aerobic denitrifying technique is a new biological way to remove the nitrogen,which has the advantages that the traditional techniques doesn＇t have, such as short process, small footprint, nitrification and denitrification can occur simultaneously. Based on the current research, the screening methods of the denitrifying bacteria were analyzed. At the same time, the elements that affect the efficiency of the nitrogen removal had been analyzed. The main elements are nitrogen, carbon, dissolved oxygen, p H, and temperature, C/N etc. At least, the aerobic denitrification technology existence question has carried on the induction. And on the basis of literature review, pointed out the aerobic denitrification technology the development direction of the future.
