反硝化聚磷污泥厌氧释磷影响因素研究_徐微

反硝化聚磷污泥厌氧释磷影响因素研究徐　微,吕锡武(东南大学环境工程系,南京210096)摘　要:采用静态试验的方法研究了温度、MLSS、VFA浓度、碳源种类等对反硝化聚磷污泥厌氧释磷的影响,研究结果表明:随着温度的升高厌氧释磷速率有所增加,但厌氧释磷速率与温度之间并不是简单的线性关系,温度对厌氧释磷的长期作用还有待考察;在一定范围内增加污泥浓度与碳源可以有效地强化厌氧释磷效果;反硝化除磷脱氮工艺处理实际生活污水时,建议厌氧池停留时间为4～6h,在工艺首端设置水解酸化池将有利于厌氧释磷效果的强化。关键词:除磷脱氮;反硝化聚磷;厌氧释磷;影响因素中图分类号:X703　　　文献标识码:A　　　文章编号:1671-1556(2009)03-0026-04＊StudyonFactorsInfluencingthePhosphorusReleaseofDenitrifyingPhosphorusRemovalSludgeinAnaerobicConditionXUWei,LUXi-wu(SchoolofEnvironmentEngineering,SoutheastUniversity,Nanjing210096,China)Abstract:ThedenitrifyingphosphorusremovaltechniquescansolveboththeproblemofscarcityofcarbonandtheconflictofSRTbetweenPAOsandnitrobacteria,soithasgoodapplicationforeground.Sincethephosphorusreleaseisthekeyprocessofdenitrifyingphosphorusremoval,itisnecessarytoinvestigatethefactorsthatmayinfluencethephosphorusreleaseprocess.Thispaperdiscussesaseriesofteststhatwereoperatedtostudytheinfluenceoftemperature,MLSS,VFAconcentrationandcarbonsource.Theresultsshowthatthephosphorusreleaseratei
