陈克玲(中国市政工程中南设计研究总院,湖北武汉430010) : 对浙江省某大型化工园区以染料废水为主的一家污水处理厂进行了二期扩建设计。根据现场中试结果,选定一级物化/生化/二级物化工艺作为该厂二期扩建废水处理工艺,介绍了各单元处理构筑物的设计参数。工程竣工后,对COD及BOD5的去除率均可达到80%以上,悬浮物(SS)去除率能达到62%以上。 : 染料废水; 化工园区; 设计参数:X703.1 :C :1000-4602(2010)18-0083-05DesignofDyeWastewaterTreatmentProcessinLarge-scaleChemicalIndustryParkCHENKe-ling(CentralandSouthernChinaMunicipalEngineeringDesignandResearchInstitute,Wuhan430010,China) Abstract: Thedesignofsecond-phaseextensionprojectofaWWTPinZhejiangProvinceisde-scribed.ThemainsourceofrawwastewaterinthisWWTPisdyewastewaterfromalarge-scalechemicalindustrypark.Accordingtotheresultsobtainedinapilot-scaleexperiment,thecombinedprocessoffirst-stagephysicochemicaltreatment,biochemicaltreatmentandsecond-stagephysicochemicaltreatmentischosenforthesecond-phaseextensionprojectoftheWWTP.Thedetaileddesignparametersoftreat-mentstructuresarepresented.TheremovalratesofCOD,BOD5andSScanreachmorethan80%,80%and62%respectivelyafterthecompletion.
