杭州七格污水厂一期工程氨氮达标运行研究书杭州七格污水厂一期工程氨氮达标运行研究张健(天津创业环保集团股份有限公司,天津300384)摘要:针对杭州七格污水处理厂一期工程出水氨氮浓度不稳定的情况,以BioWin软件为平台,搭建了符合七格污水厂一期工艺实际运行的虚拟污水厂模型,并对工艺运行参数进行优化。模拟结果表明,调整污泥浓度到4200mg/L、DO浓度到3mg/L有利于氨氮的降解,不建议通过调整内回流比来降低出水氨氮浓度。关键词:氨氮;工艺优化;达标排放中图分类号:X703文献标识码:C文章编号:1000-4602(2010)23-0058-03UptostandardDischargeofAmmoniaNitrogeninFirstphaseProjectofHangzhouQigeSewageTreatmentPlantZHANGJian(TianjinCapitalEnvironmentalProtectionCo.Ltd.,Tianjin300384,China)Abstract:AimedattheunstableeffluentammonianitrogenconcentrationinthefirstphaseprojectofHangzhouQigeSewageTreatmentPlant,usingBioWinsoftwareasaplatform,avirtualmodelofthesewagetreatmentplantthatisconsistentwiththeactualoperationofthefirstphaseprojectofHangzhouQigeSewageTreatmentPlantwasbuilt,andtheprocessoperationparameterswereoptimized.Thesimulationresultsshowthatadjustingsludgeconcentrationto4200mg/Landdissolvedoxygenconcentrationto3mg/Lisfavorablefordegradationofammonianitrogen.Itisnotsuggestedthattheeffluentconcentrationofammonianitrogenisred
