生物/化学/物理联合工艺处理高温印染废水并回用王白杨,　张　卓,　何　慧(南昌大学环境科学与工程学院,江西南昌330031)　　摘　要:　印染废水水温高、色度大、有机染料残余多,难以采用常规生物处理工艺。结合浙江某纺织印染企业生产废水的水质情况,采用以厌氧—好氧生物处理为主,后续混凝脱色、臭氧氧化、离子交换、活性炭吸附的生物—化学—物理联用工艺。中试研究结果表明,该工艺运行稳定,出水水质较好,达到了该公司染整用水水质要求。　　关键词:　内循环厌氧反应器;　曝气生物滤池;　臭氧氧化;　活性炭吸附中图分类号:X703.1　　文献标识码:C　　文章编号:1000-4602(2008)17-0075-04TreatmentandReuseofHigh-temperaturePrintingandDyeingWastewaterbyCombinedBiological/Chemical/PhysicalProcessesWANGBai-yang,　ZHANGZhuo,　HEHui(CollegeofEnvironmentalScienceandEngineering,NanchangUniversity,Nanchang330031,China)　　Abstract:　Printinganddyeingwastewaterwithhightemperature,deepcolor,high-concentrationoforganicpollutantsisdifficulttobetreatedbyconventionalbiologicalprocess.ConsideringtheprintinganddyeingwastewaterqualityofafactoryinZhejiangProvince,thecombinedbiological/chemical/physi-calprocessesincludinganaerobic/aerobictechnology,coagulationanddecoloration,ozoneoxidation,ionexchangeandactivatedcarbonadsorptionareadopted.Theresultsofpilottestshowthatthecombinedprocesseshavestabl
