中文摘要本设计对3500m3/d的某市制药废水的处理工艺进行初步设计。该市制药废水主要分为药物提取废水和其他废水，具有一般制药废水的特点，其成分复杂、有机物含量高、色度深和含盐量高，特别是生化性很差，且间歇排放，属难处理的工业废水。设计采用“气浮－UMAR－CASS”工艺对制药废水进行处理。废水水质最高CODCr：8000mg/L、最高BOD5：3500mg/L、最高SS：125mg/L。制药废水经本工艺处理后，满足《污水综合排放标准》（GB8978-1996）一级标准。关键词：制药废水气浮UMARCASSTHETREATMENTPROCESSPRELIMINARYDESIGNFORPHARMACEUTICALWASTEWATERABSTRACTTreatmentprocessofthedesignof3500m3/dinpharmaceuticalwastewaterpreliminarydesign.Thepharmaceuticalwastewaterconsistsofextractionwastewaterandotherwastewaterhasthecharacteristicsofgeneralmedicine,pharmaceuticalwastewater,itscomplexcomposition,highorganiccontent,colordepthandhighsaltcontent,especiallybiochemistryisverypoor,andintermittentdischarge,belongstotheindustrialwastewatertreatment.Thedesignofthe"air－UMAR－CASS"processtotreatpharmaceuticalwastewater.ThewaterqualitythehighestCODCr:8000mg/L,BOD5:3500mg/LSS:125mg/L,thehighestpeak.Pharmaceuticalwastewaterbytheprocess,"Integratedwastewaterdischargestandard"(GB8978-1996)standard.Keywords:pharmaceuticalwastewater；flotation；UMAR；CASS目录第一章设计背景.................................................11.1设计题目.................................................11.2设计水质水量.............................................11.3排放标准.................................................11.4设计原则.................................................21.5设计依据.................................................21.6设计范围.................................................3第二章处理工艺方案选择.........................................42.1处理工艺比选.............................................42.1.1工艺选择原则.......................................42.1.2工艺比选...........................................42.1.3比选结果...........................................52.2设计工艺流程.............................................62.2.1工艺流程...........................................62.2.2工艺流程详述.......................................72.2.3化学品投加.............................................9第三章主要构筑物设计计算.......................................93.1集水井的设计计算.........................................93.1.1设计说明...........................................93.1.2设计参数...........................................93.1.31#集水井设计计算...................................93.1.42#集水井设计计算.................................103.1.51#集水井提升泵泵选型.............................113.1.62#集水井提升泵泵选型.............................123.2调节沉淀池的设计计算....................................123.2.1设计说明...........................................123.2.2设计参数...........................................123.2.3排泥系统设计计算..................................133.2.4进出水系统设计....................................143.2.5设备选型..........................................153.3调节沉淀池的设计计算....................................163.3.1设计说明..........................................163.3.2设计计算..........................................163.4循环池设计计算..........................................173.4.1设计说明..........................................173.4.2设计计算..........................................
