I某造纸厂废水处理设计摘要本设计内容为造纸废水处理设计。根据国家提出的排放标准进行处理废水，总设计的进水为5000t/d。进水中COD6000-8000mg/L，SS2000-3000mg/L，氨氮30-50mg/L，出水要求COD浓度小于300mg/L，SS小于70mg/L，氨氮小于15mg/L，pH在6-9范围内。在某个构筑物单独处理中，主要需要完成其平面图剖面图加上一部分详图。污水的处理按照各构筑物的布置进行处理：污水通过格栅，调节池，UASB，中沉池，A/O工艺,絮凝沉淀池。污泥的主要的处理流程为：从中沉池UASB等构筑物中排出的污泥进入浓缩池，然后进入脱水机房，UASB和A/O中的污泥储存在浓缩池内，达到一定容量到脱水机房，最后外运处置。UASB工艺具有良好的降低COD负荷的功能，A/O工艺能去除污水中的氨氮。关键词：造纸废水，UASB工艺，A/O工艺IIABSTRACTThedesigncontentforthepapermakingwastewatertreatmentdesign.WastewatertreatmentiscarriedoutaccordingtotheemissionstandardsproposedbytheState.Thetotalwaterintakeis5000t/d.TheCODconcentrationislessthan300mg/L,theSSislessthan70mg/L,theammonianitrogenislessthan15mg/L,thepHisintherangeof6-9Withinrange.Inaseparatestructureofthebuilding,themainneedtocompletetheplansectionwithapartialview.Sewagetreatmentinaccordancewiththelayoutofthestructuretodealwith:sewagethroughthegrille,regulatingpool,UASB,inthepool,A/Oprocess,flocculationsedimentationtank.Themainsludgetreatmentprocessis:fromthesinkpoolUASBandotherstructuresinthesludgedischargedintothecondensatepool,andthenintothedehydrationroom,UASBandA/Ointhesludgestoragetank,toacertaincapacitytothedehydrationroom,Thefinalhandlingofdisposal.UASBprocesshasagoodfunctiontoreducetheCODload,A/Oprocesscanremoveammoniainthesewage.Keywords:papermakingwastewater,UASBprocess,A/Oprocess1目录第一部分设计说明书...................................................................................................4第一章概述...........................................................................................................41.1设计概况.................................................................................................41.2基本设计参数.........................................................................................51.3废水水质特点.........................................................................................71.4地理位置.................................................................................................7第二章工艺流程的确定.......................................................................................82.1厌氧法的比较.........................................................................................82.2厌氧处理工艺确定..................................................................................82.3好氧工艺的确定.....................................................................................92.4方案比选................................................................................................102.5流程说明................................................................................................112.6去除率...................................................................................................12第三章主要构筑物介绍.....................................................................................133.1格栅.......................................................................................................133.2调节池.....................................................................................................
