倒置A_2_O工艺硝化除磷调控的实例分析_张静

倒置A2/O工艺硝化除磷调控的实例分析张　静(北京城市排水集团有限责任公司,北京100012)　　摘　要:　北京清河污水处理厂一期工程采用倒置A2/O工艺,运行2年以来,在保证出水NH3-N达标的情况下仅通过生物除磷就使出水TP≤0.3mg/L。实践证明,在工艺调控中掌握一些关键控制点,使倒置A2/O工艺的硝化除磷能力充分发挥,是高效生物除磷的关键。　　关键词:　污水处理厂;　倒置A2/O工艺;　硝化除磷;　工艺控制中图分类号:X703.1　　文献标识码:C　　文章编号:1000-4602(2007)20-0093-05CaseAnalysisonControlofInverseA2/OProcessforNitrificationandPhosphorusRemovalZHANGJing(BeijingDrainageGroupCo.Ltd.,Beijing100012,China)　　Abstract:　InverseA2/OprocessisusedinthefirstphaseprojectofBeijingQingheWastewaterTreatmentPlant.Duringitsoperationinthepasttwoyears,theeffluentTPreachedbelow0.3mg/Lonlythroughbiologicalphosphorusremovalundertheconditionofensuringtheup-to-standardoftheeffluentNH3-N.Thepracticeprovesthatitisthekeypointforhigh-efficiencybiologicalphosphorusremovaltomastersomecontrolpointsintheprocessadjustmentandcontroltogivefullplaytothegreaternitrifica-tionandphosphorusremovalcapabilityofinverseA2/Oprocess.　　Keywords:　wastewatertreatmentplant;　inverseA2/Oprocess;　nitrificationandphosphorusremoval;　processcontr
