摘    要:目前 ,城市污水处理厂的处理对象包括COD、BOD5、SS和氮、磷等营养物质。就氮磷脱除而言 ,一般需涉及硝化、反硝化、微生物释磷和吸磷等过程。由于各过程的要求不同 ,在同一污水处理工艺系统中就不可避免地产生了各过程间的矛盾关系。针对泥龄问题、碳源问题、硝酸盐问题、系统的硝化和反硝化容量问题、释磷吸磷的容量问题进行了探讨

关 键 词:污水处理  生物除磷脱氮  工艺系统  矛盾关系

Abstract:The treatment parameters in municipal wastewater treatment plant include COD, BOD 5, SS, N and P etc. Biological N-P removal involves in processes such as nitrification, denitrification, phosphorus release and uptake. The paradoxical relationships are inevitably produced in the same treatment system because of the different requirements of different treatment processes. This paper analyzed the problems of sludge age, carbon sources, nitrate, capacity of nitrification and denitrification, capacity of phosphorus release and uptake. Such analysis is conducive to improve the understanding of paradoxical relationships in biological phosphorus and nitrogen removal process.
