含磺胺嘧啶和酮基布洛芬的化学合成制药生产废水处理研究-45b73e0e172ded630a1cb653作者:陈曦,男,1972年生,博士,研究方向为化工环保。＊国家“863”计划项目(No.2002AA647020)。含磺胺嘧啶和酮基布洛芬的化学合成制药生产废水处理研究＊陈曦(重庆师范大学化学学院,重庆400047)摘要含磺胺嘧啶(SD)和酮基布洛芬(KP)的化学合成制药生产废水对生物处理有较强的抑制作用。实验结果表明,通过对厌氧菌和好氧菌的驯化、筛选和复配,采用酸析作预处理,结合厌氧/好氧串联工艺可有效降低废水的COD、BOD5和NH3-N;经酸析和厌氧水解酸化处理后,COD去除率为85%,再经15h的好氧处理,COD去除率可达94%,运行效果稳定。关键词生物处理磺胺嘧啶酮基布洛芬制药废水TreatmentofapharmaceuticalplantwastewatercontainingsulfadiazineandketoprofenChenXi.(SchoolofChemis-try,ChongqingNormalUniversity,Chongqing400047)Abstract:Atreatabilitystudywasperformedonthewastewater(pH=11.5,COD=2525mg/L,BOD5=915mg/L,NH3-N=258mg/L)fromapharmaceuticalplantproducingsulfadiazine(SD)andketoprofen(KP).Excel-lenttreatmentresultswereobtainedby3sequentialbatchtreatmentstepsofacidification/neutralization,anaerobicbiodegradationandaerobicbiodegradation.DuplicatedexperimentalrunswereconductedtoobtaindataofCODde-clineduringacidification/neutralization,CODdeclineandgasproductionduringanaerobicdegradationat34℃,andCODdeclineduringthefinalae
