临沂污水处理厂升级改造工程工艺优化分析_崔宝军

临沂污水处理厂升级改造工程工艺优化分析崔宝军(临沂首创水务有限公司,山东临沂276000)　　摘　要:　临沂污水厂原设计规模为15×104m3/d,一期工程(8×104m3/d)采用底曝氧化沟工艺,二期工程(7×104m3/d)采用A/A/O工艺,总排口出水水质基本达到一级B标准。此次升级改造,将原一期工程的底曝氧化沟改造成复合式好氧池,并配套前置缺氧池,对原二期工程的厌氧段、缺氧段进行水力优化,增加转盘式过滤器,使出水水质达到一级A排放标准,不需另外征地,可为类似污水处理厂升级改造提供参考。　　关键词:　污水处理厂;　升级改造;　A/A/O工艺;　前置反硝化;　复合式好氧池;　转盘滤池;　脱氮除磷中图分类号:X703　　文献标识码:C　　文章编号:1000-4602(2009)24-0055-03OptimizedAnalysisonUpgradingandReconstructionProjectofLinyiWastewaterTreatmentPlantCUIBao-jun(LinyiCapitalWaterCo.Ltd.,Linyi276000,China)　　Abstract:　TheoriginaldesigncapacityofLinyiWWTPwas15×104m3/d,thefirst-phaseproject(8×104m3/d)withthebottomaerationoxidationditchprocess,thesecond-phaseproject(7×104m3/d)withA/A/Oprocess,theeffluentqualityatthegeneraloutletbasicallyreachedthefirstlevelBcrite-ria.Intheupgradingandreconstructionproject,thebottomaerationoxidationditchisreconstructedintoacompoundaerobictankwithpre-anoxictank,andtheanaerobicstageandtheanoxicstagearehydrauli-callyoptimized.TheeffluentqualitywillachievethefirstlevelAcriteriawi
