污水处理厂中反硝化除磷工艺的应用_张丹

环境保护污水处理厂中反硝化除磷工艺的应用张　丹1,胡　乐2(1天津市市政工程研究院,天津　300074;2白求恩军医学院,河北　石家庄　050081)摘　要:综述了反硝化除磷技术的原理和实现反硝化脱氮除磷的主要工艺。该工艺是根据反硝化聚磷菌(DPB)的摄磷特点而开发的新型生物脱氮除磷工艺,以其特有的“一碳两用”和“双泥系统”,有效解决了常规生物脱氮除磷工艺的碳源供求矛盾和泥龄控制问题,可同时获得较高的除磷和脱氮效率。目前常见的主要工艺有A2N-SBR工艺、BCFS工艺和DEPHANOX工艺。关键词:反硝化除磷;A2N-SBR;BCFS;DEPHANOXDenitrifyingDephosphatationProcessinWastewaterTreatmentZHANGDan1,HULe2(1TianjinMunicipal＆HighwayEngineeringResearchInstitute,Tianjin300074;2BethuneMilitaryMedicalCollege,HebeiShijiazhuang050018,China)Abstract:Themechanismsandnewavailableapproachesofdenitrifyingdephosphatationwereelaborated.ThisprocessesweredevelopedbasedontheP-uptakecapabilityofthedenitrifyingphosphorusremovalbacteria(DPB)underanoxiccondition.Theproblemsofcarbonsourcesupplyandsludgeagecontrolcouldbeeffectivelysolvedintheprocessesbymeansof“onecarbonsourcefortwouses”and“two-sludgesystem”.Meanwhile,phosphorusandnitrogencanberemovedefficiently.Keywords:denitrifyingdephosphatation;A2N-SBR;BCFS;DEPHANOX近年来,随着工业化和城市化程度的不断提高,合成洗涤剂、化肥和农药被广泛使用,大量氮、磷营养物进入
