200927好氧生化法处理印染废水经验探讨崔红涛(, 071051) :印染废水具有水量大、有机污染物含量高、色度深、碱性大、水质变化大等特点,属难处理的工业废水,水质差别很大:COD在400~1000mg/L、色度在100~400倍。目前国内比较常用的印染污水处理工艺,一般采用物化、生化的工艺技术路线,包括生物活性污泥池处理法、物理化学处理法和膜处理法等。现主要对好氧生化法调试过程进行论述。:印染废水;好氧生化法;工程调试DISCUSSIONONEXPERIENCEINTREATMENTOFPRINTINGANDDYEINGWASTEWATERBYAEROBIC-BIOCHEMICALMETHODCuiHongtao(GeophysicalExplorationAcademyOfChinaMetallurgicalGeologyBureau,Baoding071051,China)Abstract:Aprintinganddyeingwastewaterfeatureshighcontentoforganicpollutants,deepcolority,highalkalinity,andthewaterqualityofmajorchangesetc,whichisdifficulttotreat.WhoseCODandcolorityareintherangeof400~1000mg/Land100~400fold.Atpresent,theprocessesusedforprintinganddyeingwastewatertreatmentarethegeneralphysico-chemicalandbiochemicaltechnology,includingthebiologicalactivatedsludgetreatmentponds,chemicaltreatmentandphysicaltreatment.Inthispaper,thedebuggingoftheaerobicchemicalandbiologicalmethodisdiscussed.Keywords:dyeingwastewater;aerobicbiochemicalmethod;projectcommissioning0 ,,(、、、、)、()、()()4,[1]。,,,,COD。1 ,BOD5/COD,、COD。A/O,,、。,。,。、、、,[2]。,GB8978-96《》:COD100mg/L,40。,,。2 、、、、,20%,COD。、、、[2]。,,BODCOD,。,、,。588DOI:10.13205/j.hjgc.2009.s1.021 2009273 3.1 工艺流程1。1 3.2 工艺设计参数1)。。,,。2)。、,pH。,pH,。2。6h。3)。,,、,、CODSS。。pH=8.5~9。1。2.8h。4)。,,。,,,,[1]。,,。11.96h。5)。,,。,。,11.15m3/min。20.31h。6)。,。,,。,,。3.2h。7)。。。,;,,[2]。,。。57.70h。4 4.1 准备过程、,、,、、。4.2 工程调试4.2.1 :。1),,,,10%,3h,20%6h,,,。2),,,,,,,。,。4.2.2 、3。,。,,,,589 200927,,,、、,,,、、,,。,、,。。、。,。,C、N、P,,。。,,,。,。。4.2.3 1)。、,CNP,[3]。,,BODCOD,、、、。。。,pH,COD40%,。2)。,CODSS,PACPHP,。,PACPHP。,。3)。,ph、、,,,,。5 1。1 pHCODSS6.23~6.907.66~8.10/(mg·L-1)54958.127.2/%89.495/(mg·L-1)17432/%81.6/40040/%906 ,、。,、。,,。[1].[M].,2005.[2],,.[M].:,2004.[3],.[M].:,1995.5. 071051 139 (0312)5905368E-mail baodinghuanbao@163.com2009-03-18590
