生物强化脱色处理印染废水的中试研究_徐灏龙

生物强化脱色处理印染废水的中试研究徐灏龙,　白俊跃,　章一丹,　王慧蓉(国家环境保护水污染控制工程技术<浙江>中心,浙江杭州310007)　　摘　要:　为解决印染废水生化处理效果差的难题,开发了复合水解酸化/悬浮生物滤池的印染废水生化处理工艺,并在此基础上投加专性脱色菌进行生物强化脱色处理。结果表明,在稳定运行条件下,系统对色度的去除率提高了10%～20%,对色度的总去除率达到80%以上,对COD的去除率达到90%左右。可见,通过生物强化技术提高生化处理的脱色能力是可行的。　　关键词:　印染废水;　复合水解酸化;　悬浮生物滤池;　脱色中图分类号:X703　　文献标识码:C　　文章编号:1000-4602(2010)23-0091-03PilotStudyonTreatmentofPrintingandDyeingWastewaterbyBioaugmentationTechnologyXUHao-long,　BAIJun-yue,　ZHANGYi-dan,　WANGHui-rong(National<Zhejiang>EngineeringCenterforEnvironmentalProtectionandWaterPollution,Hangzhou310007,China)　　Abstract:　Inordertosolvetheproblemofpoorefficiencyofbiochemicaltreatmentofprintinganddyeingwastewater,acombinedprocessofhybridhydrolysisacidificationandsuspendedbiologicalfilterwasdeveloped,anddecolorizingbacteriawereaddedinbioaugmentationforcolorremoval.Theresultsshowthatunderthestableoperationcondition,theremovalrateofcolorisincreasedby10%to20%,andthetotalremovalratesofcolorandCODreachmorethan80%andabout90%.Itisconcludedthatthebioa
