摘要
目前 ,城市污水处理厂的处理对象包括BOD5、SS和氮、磷等营养物质。就脱氮与除磷而言 ,由于各自过程的要求不同 ,二者之间存在一定的矛盾关系。讨论了城市污水生物除磷脱氮的基本原理 ,综述了城市污水脱氮除磷机理方面的研究现状和进展。分析了脱氮与除磷二者之间的矛盾关系 ,在此基础之上对碳氮磷合并去除工艺进行了比较 ,并对以后开展这方面的研究提出了展望。
The treatment parameters in municipal treatment plant include COD, BOD5, SS, N and P etc. The paradoxical relationships are inevitably produced because of the different requirements on denitrification and phosphor removal. In this paper, the fundamental mechanism of biological denitrification and phosphor removal and their present situation and progress are presented. On the basis of analysis on the paradoxical relationship between biological denitrification and phosphor removal, the development of denitrification and phosphor removal process was discussed and the further study in this field was proposed.
