天津市污水处理厂初步设计方案.doc

:悬浮物(SS):200mg/L;五日生化需氧量(BOD5):200mg/L;化学需氧量(CODcr):400mg/L;总氮(N):40mg/L;总磷(P):;重金属及有毒物质:微量;处理后地水质要求:BOD5≤20mg/L;SS≤20mg/L;N≤15mg/L;P≤1mg/L;根据设计要求和求新地思想,该污水处理工程进水中氮、磷含量均偏高,在去除BOD5和SS地同时,还需要进行脱氮除磷处理,,具有广泛地适应性,、格栅、污水泵房、曝气沉砂池、氧化沟、接触池、浓缩池、,且工艺流程简单,省去了初沉池、二沉池、消化系统和回流设备,节省了基建投资和运行费用,同时曝气设备和构造形式多样,运行灵活,管理方便,保证出水达到污水排放标准,:,:Suspendedsubstance(SS):200mg/L;Thebiochemicaloxygendemand(BOD5)offivedays:200mg/L;Thechemicaloxygendemand(CODcr):400mg/L;Totalnitrogen(N):40mg/L;Totalphosphorus(P):;Heavymetalandnoxioussubstance:Trace;Treatedwaterqualityisrequired:BOD5≤20mg/L;SS≤20mg/L;N≤20mg/L;P≤1mg/L;Accordingtothedesigningrequirementandthoughtoflookingfornovelty:thecontentofnitrogenandphosphorusareonthehighsideinthisprojectwaterquality,soitshoudbedealedwith,,parativelyextensivedenitrificationcraftsatpresent,namely,,totallysuitableforrealityoriginallydesigned',grid,sewagepumpinghouse,earateandsinkingsandpool,oxidizingditch,contactingpool,concentrationtank,,andtheprocedureissimple,managementisconvenient,donotneedtoaddthefirstsinkingpool,thesecondsinkingpool,,realizingautomationtotallyatthesametime,easytomanage,makingthetreatedwaterreachsewagedischargestandard,:Typesofthreeditchoxidizingditch,Grid,Concentrationpool,Pumpinghouse,Newcraft个人收集整理勿做商业用途第一部分说明书设计原始资料(一)概况:天津市是我国直辖市之一,随着人口地增加,工业地发展,人民生活水
