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C0D6000-8000mg/L,SS2000-3000mg/L,氨氮30-50mg/L,出水要求C0D浓度小于300mg/儿，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，AO工艺，絮凝沉淀池。污泥的主要的处理流程为：从中沉池USB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AO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ABSTRACTThe design content for the papermaking wastewater treatment design.Wastewatertreatment is carried out according to the emission standards proposed by the State.Thetotal water intake is 5000 t/d.The COD concentration is less than 300mg /L,the SS is lessthan 70mg /L the ammonia nitrogen is less than 15mg /L,the pH is in the range of 6-9Within range.In a separate structure of the building,the main need to complete the plan sectionwith a partial view.Sewage treatment in accordance with the layout of the structure todeal with:sewage through the grille,regulating pool,UASB,in the pool,A /O process,flocculation sedimentation tank.The main sludge treatment process is:from the sink poolUASB and other structures in the sludge discharged into the condensate pool,and theninto the dehydration room,UASB and A /O in the sludge storage tank,to a certaincapacity to the dehydration room,The final handling of disposal.UASB process has a good function to reduce the COD load,A/O process can removeammonia in the sewage.Keywords:papermaking wastewater,UASB process,A/OprocessII目录第一部分设计说明书.…第一章概述1.1设计概况.…41.2基本设计参数.…1.3废水水质特点.1.4地理位置…7第二章工艺流程的确定…2.1厌氧法的比较2.2厌氧处理工艺确定2.3好氧工艺的确定2.4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.3.2调节池133.3UASB反应器.133.4中沉池…3.5A/0池.143.6二沉池.3.7污泥浓缩池.第四章工程设计164.1处理厂位置..164.2平面布置.161
