物化生化组合工艺处理分散染料废水_王白杨书物化生化组合工艺处理分散染料废水王白杨，曾悦，邱攀，周鑫(南昌大学资源环境与化工学院，江西南昌330031)摘要:某化工厂以化学合成法生产分散染料，产生的染料废水具有高COD、高氨氮、可生化性差等特点，原处理工艺无法达标排放。改造工程采用铁碳芬顿+ABＲ+UASB+A/O+芬顿组合工艺处理该分散染料废水。运行结果表明，COD去除率达到93%，NH3－N去除率达到82%，出水水质满足当地化工产业园区污水处理厂纳管标准。关键词:分散染料废水;芬顿工艺;A/O工艺;纳管排放中图分类号:TU993文献标识码:C文章编号:1000－4602(2018)14－0080－04TreatmentofDisperseDyeWastewaterbyaCombinedPhysical-chemicalandBiochemicalProcessWANGBai-yang，ZENGYue，QIUPan，ZHOUXin(CollegeofEnvironmentalＲesourceandChemicalEngineering，NanchangUniversity，Nanchang330031，China)Abstract:Achemicalplantproducesdispersedyethroughchemicalsynthesismethod．SincetheproducedwastewaterhasthefeaturesofhighCOD，highammonianitrogen，poorbiochemicaldegradationandsoon，theoriginaltreatedwastewaterqualitycouldnotmeetthedischargestandard．Basedontheoriginalprocess，acombinedprocessofferric-carbonFenton，ABＲ，UASB，A/O，andFentonareadopt-edtotreatthedispersedyewastewater．ActualoperationresultsindicatedthattheCODremovalratereached93%，NH3－Nremovalratereached82%，andalltheeffluentinde
