本科毕业设计（论文）膜SBR工艺处理混合制药废水学院环境科学与工程学院专业环境工程年级班别2009级（3）班学号3109007661学生姓名曾浩权指导教师谢武明2013年6月设计总说明制药废水的特点是成分复杂，有机物含量高、毒性大、色度深及含盐量高，可生化性较差，且间歇排放，属难处理的工业废水。制药废水一般难以降解，可长期存在于环境中。本设计针对300吨/天制药废水，进水水质为：BOD5：130mg/L，CODCr：400mg/L，pH:6-9，SS:150mg/L。出水水质达到国家工业废水二级排放标准。针对该制药废水的特点，参照国内外经验，运用膜SBR工艺，废水经酸化调节池，初沉池，膜SBR池后，有效降低废水中的COD、BOD,使废水出水水质达到国家工业废水二级排放标准。相对于其他工艺，采用膜SBR工艺有节能，占地少，造价低，无须处理污泥，运行成本低等优点。本设计处理水量为300m³/d，为小型工程，工程地点设置在制药厂区内，方便处理，经处理后的出水直接运用于制药厂区绿化用水。经计算，工程总投资为105万元左右，每立方处理水成本在0.5元左右。关键词：混合制药废水,膜SBR工艺,酸化调节DesignIlluminatePharmacicalwastewaterischaracterizedbyitscomplexcomponets,highconcentrationsoforganicmatter,hightoxicity,deepcolorandhighsaltcontents，poorbiodegradability,andintermittentemissions,whichmakeitindustrialwastewaterhardtodealwith.Itisalsoverydifficulttodegrade，andcanexistintheenvironmentforalongtime.Someoftheorganicpollutantsexistinpharmaceuticalwastewaterareeasytocausewaterpollution,andhaveposedahugethreattohumenthealth.WiththedevelopmentofChinesepharmaceuticalindustry,pharmaceuticalwastewaterhasgraduallybecomeoneofthemajorsourcesofpollution.Andhowtohandlethepharmaceuticalwastewaterbecomesadifficultprobleminenvironmentprotection.Thedesignforthepharmaceuticalwastewaterbyusingmembranetechnology,SBR,caneffectivelyreducethewastewaterCOD,BOD,theeffluentqualitycanmeetthenationalwastewaterdischargestandardoftwograde.Comparedwithotherprocess,usingthemembraneSBRprocesshasenergysaving,lesslandoccupation,lowcost,nosludgetreatment,hastheadvantagesoflowoperatingcost.Thedesigntreatmentcapacityis300mUniversity/d,forsmallprojects,projectlocationconvenientsettingprocessinginthepharmaceuticalfactory,,thetreatedeffluentisdirectlyusedinpharmaceuticalplantgreenwater.Bycalculation,watertreatmentcosts0.5yuanpercubic.Keywords:HybridPharmaceuticalWastewater,MembraneSBR,Acidification目录1绪论.............................................................51.1制药工业生产概况............................................51.2制药废水的种类、来源及特点..................................61.2.1生物制药废水...........................................61.2.2化学制药废水...........................................61.2.3其他制药废水...........................................72制药废水处理技术及发展............................................82.1制药废水生物处理技术.......................................82.2制药废水物化处理技术.......................................122.3制药废水化学处理技术.......................................122.3.1高级氧化技术.........................................122.3.2Fe-C处理法[8].......................................132.3.3电解.................................................132.3.4焚烧.................................................133水质分析及工艺流程的选择.........................................143.1进水水质及出水水质要求.....................................143.2工艺流程的选择.............................................143.3废水处理工艺流程........................................
