曝气生物滤池法（BAF）处理某医院废水工程设计

曝气生物滤池法（BAF)处理某医院废水工程设计内容摘要医院废水主要是由医院医院门诊、试验室、医院病房、洗衣店、急诊科、影象室、诊室等排出来，其由来和成份十分复杂。此外废水中含有大量病原菌、病毒感染、药物放射性元素，具备室内空间环境污染、急性感染和潜伏感染的特征。医院废水没经解决立即排出，并对生态环境保护、身体健康、人身安全导致极大威协。因而，医院废水处理是保护生态环境保护与人民健康的重要每日任务之一，医院污水处理厂基本建设是解决医院污水的关键方法之一。本设计方案经历了比照接触氧化法、曝气滤池、传统式活性污泥、AWAO、SBR法、AB法等。最后采用占地总面积小、解决效果明显、运作平稳、项目投资低曝气滤池法，不用二沉池，能降低一部分建设费用。本设计方案偏重于曝气过虑加工工艺。医院不同区域不一样的来源废水通过相对应预备处理后，采用粗格栅、细格栅、加强絮凝沉淀池一级处理方法，达到曝气滤池渗水要求及曝气滤池反洗水冲击性。二级处理采用BIOS tyry(过滤装置解决，紫外线杀菌后排至市政管网。在规划环节中，根据对各个建筑物设计测算，进行框架结构的平面图轮廊、工业厂房布局和建筑立面，进行全部解决站的设计方案。关键词：医院废水；曝气生物滤池(BAF)法；二级污水处理；BIOSTYR滤池AbstractsHospital wastewater is mainly discharged from the hospital's diagnosis andtreatment rooms,laboratories,wards,laundry rooms,radiology departments,imaging rooms,and operating rooms.The source and composition of thewastewater are very complex.And wastewater contains a large number ofpathogenic bacteria,viruses,chemical agents and radioactive materials,withspace pollution,acute infection and latent infection characteristics.If thehospital wastewater is discharged directly and not treated accordingly,it willpose a great threat to the ecological environment to human health and life safety.Therefore,it is one of the important tasks to maintain the ecologicalenvironment and people's health to do a good job in hospital wastewatertreatment,among which the construction of hospital sewage treatment station isone of the main means to treat hospital wastewater.After comparing thebio-contact oxidation method,aeration biofiltration cell,traditional activatedsludge method and A/A/0,SBR method,AB method,etc.,this design finallyadopts the aeration biofiltration cell method which covers less area,has goodtreatment effect,has stable operation and invests less,and the process does notrequire two sinks to reduce part of the construction cost.This design revolvesaround the aeration biofiltration tank process,the hospital area of differentsources of waste water after the corresponding pretreated,the use of coarsegrille,fine grille,strengthen flocculation sedimentation pool of the first-leveltreatment to meet the aeration biofiltration tank water requirements and aerationbiofiltration tank back-flushing water impact;The design process is completedthrough the design and calculation of each structure,the flat profile of the mainstructure and the layout and elevation map of the plant,so as to complete thedesign of the whole processing station.Keywords:Hospital Wastewater;Biological Aerated Filter (BAF)method;Secondary Sewage Treatment;BIOSTYR Filter.目录一、医院废水进行治理的必要性，(一)概况(二)医院废水解决重要性，二、医院废水解决现况.(一)废水水质.…2(二)建设规模与治理目标，21.污水处理厂建设规模.….22.设计进出水水质...2(三)设计依据.2三、工艺方案论证.3(一)工艺方案选择原则….3(二)医院废水处理工艺简介.3(三)3.A/A/0过程简述(四)处理工艺的选择..51.曝气生物滤池的原理及特征..62.曝气生物滤池的工艺.63.BIOCARBONE...4.BIOFOR........75.BIOSTYR..8(五)工艺流程的说明8(六)工艺流程图….11四、主要处理构筑物计算….11(一)格栅.….111.设计说明112.格栅工艺计算….12(二)集水井….14(三)絮凝沉淀池.141.设计说明….14
