【摘要】 结合近年来国内外除磷脱氮的最新研究成果,对好氧颗粒污泥除磷脱氮的机理及工艺进行了探讨和研究。研究表明通过适当的SBR定向培养,可以在颗粒污泥中培养出不同的微生物菌群(硝化菌、反硝化菌、聚磷菌、反硝化聚磷菌等),使其能够实现同步除磷脱氮,从而为污水生物除磷脱氮工艺研究提供了一个新思路。更多还原

【Abstract】 Based on the latest results of the study of dephosphorization and denitrification in China and outside China, the mechanism of and process for dephosphorization and denitrification by aerobic granular sludge were approached and studied. The results of the study showed that different colonies of microorganisms(nitrifiers, denitrifiers, phosphorus-accumulating organisms, denitrifying phosphorus-accumulating organisms, etc.) can be cultivated in granular sludge through appropriate orientated cultivation in sequencing batch reactor (SBR)to enable it to realize simultaneous dephosphorization and denitrification, which provides a new thinking for the study of the biological dephosphorization and denitrification of waste water.更多还原
