—UASB潘碌亭, 束玉保, 罗华飞, 李 璐, 缪强强(同济大学污染控制与资源化研究国家重点实验室,上海200092) : 采用催化微电解—UASB组合工艺处理羧甲基纤维素(CMC)生产废水,考察了废水pH、反应时间、温度、停留时间对COD去除率的影响。结果表明,当系统进水COD为20g/L时,在铁炭微电解反应器进水pH值为3.5、反应时间为75min及UASB反应器温度为37℃、厌氧停留时间为44h的条件下,出水COD1200mg/L,为后续好氧生化处理出水达标排放奠定了基础。 : 微电解; UASB; 羧甲基纤维素生产废水:X703 :C :1000-4602(2009)03-0070-03CatalyticMicroelectrolysis/UASBProcessforTreatmentofCarboxymethylCelluloseProductionWastewaterPANLu-ting, SHUYu-bao, LUOHua-fei, LILu, MIAOQiang-qiang(StateKeyLaboratoryofPollutionControlandResourcesReuse,TongjiUniversity,Shanghai200092,China) Abstract: Thecatalyticmicroelectrolysis/UASBprocesswasusedtotreatwastewaterfromcar-boxymethylcellulose(CMC)production.TheeffectofpH,reactiontime,temperatureandhydraulicre-tentiontimeontheremovalrateofCODwasinvestigated.TheresultsshowthatundertheconditionsofrawwastewaterpHof3.5,reactiontimeof75min,UASBtemperatureof37℃andHRTof44h,theCODconcentrationcanbereducedfrom20000mg/Lintheinfluentto1200mg/Lintheeffluent.Theprocesslaysafoundationforthesubsequentaerobictreatment.
