赤霉素生产废水处理工程改造赤霉素生产废水处理工程改造王白杨果志强凌晓赵方方(南昌大学环境与化学工程学院，南昌330031)摘要:某生物制药公司生产废水有机物浓度高，水质复杂，属难降解废水。原处理工艺对萃余液处理不够彻底，出水难以达标排放，因而对原处理工艺进行改造，即在原有构筑物基础上采用UASB+二级A/O工艺。运行结果表明:出水水质稳定，符合GB8978－1996《污水综合排放标准》的二级标准，COD去除率高于95%，ρ(氨氮)<10mg/L。关键词:生物制药;工程改造;UASB;A/ORECONSTRUCTIONOFGIBBERELLINSWASTEWATERTREATMENTPROJECTWangBaiyangGuoZhiqiangLingXiaoZhaoFangfang(CollegeofEnvironmentandChemistry，NanchangUniversity，Nanchang330031，China)Abstract:Wastewaterfromabiopharmaceuticalcompanycontaininghighconcentrationorganicsubstancesandcomplexwaterqualityisdifficulttotreat.Theoriginaltreatmentcan’tcompletelyreducetheextractionraffinateresultinginbadqualityofeffluent.Therefore，UASBanddoubleA/Oreactorsareusedtotreatthiswastewaterbasedontheoriginalstructure.Theresultshowsthatthequalityofeffluentisstableandcanmeetthesecond-orderof“theIntegratedWastewaterDischargeStandard”(GB8978－1996)，CODremovalrateismorethan95%，andammoniancontentislessthan10mg/L.Keywords:bio-pharmacy;reconstructionofproject;UASB;A/O1工程概况江西某生物制药公司是全国最大
