*李东伟1,2, 袁 雪1, 李 斗1, 王克浩1, 杨 建1(1. , 400044;2. , 400044):依据二相厌氧机理设计实验反应器,采用人工配制水样作为实验用水,利用色谱-质谱联动仪分析二相厌氧各阶段水质的特性。实验结果表明:经二相厌氧反应后,有机物的种类没有减少,相反增加了许多水解、酸化反应的小分子中间产物,产酸反应器将大分子难降解化合物降解为易降解酸性小分子化合物,可生化性有所提高,再经过产甲烷反应器最终处理后,出水的化合物种类和含量有明显减少。:二相厌氧;色谱-质谱;有机废水;特性:X5 :A :1006-7329(2006)02-0083-03StudyonCharacteristicsofOrganicWastewaterwithTwo-PhaseAnaerobicTreatmentLIDong-wei1.2,YUANXue1,LIDou1,WANGKe-hao1,YANGJian1(1.CollegeofResourceandEnvironmentalScience,ChongqingUniversity,Chongqing400044,P.R.China;2.TheKeyLaboratoryoftheEx-ploitationofSouthwestResourcestheEnvironmentalHazardsControlEngineering,MinistryofEducation,Chongqing400044,P.R.China)Abstract:Basedontwo-phaseanaerobicmechanism,aprocessingreactorwasdesigned;andthewastewaterwithhighconcentrationdischargedintheprocessofproductionofChinesetraditionalmedicineiscarefullyanalyzedbytheuseofGC-MS.Theresultsobtainedintheexperimentshowthattheby-productsofhydrolizationandacidificationin-creaseinsteadofthereductionoforganicmatters'sort,andatthesametimethatthenumberandtheamountofcom-poundsintheeventualprocessedwaterareapparentlyreduced,theacid-producingreactormaydecomposecompoundswithgreatmoleculeintothosewithsmallmoleculeandaccordinglyimprovethebiologicallyprocessingability.Keywords:Twophaseanaerobic;GC-MS;organicwastewater;characteristics (TwoPhaseAnaerobicDiges-tion,TPAD)2070(Ghosh)(Pohland)。1977。,,。-,。1 ,COD∶N∶P=300∶5∶1N、P()。:COD=2500~8000mg/L,SS=1000~4000mg/L,BOD5=1500~6000mg/L,pH4~7。1 1CODcr/mgL-160002BOD5/mgL-127003pH62 2.1 UASB,[1],1。UASB。第28卷 第2期2006年4月 重庆建筑大学学报JournalofChongqingJianzhuUniversity Vo.l28 No.2Apr.2006*:2005-11-15:(CSTC,2005BB7253):(1966-),,,,,。1.;2.;3.;4.;5.;6.;7.;8.;9.1 2.2 [2,3],、,。,,,;,。(SMPA)。,,,,。,,。3 3.1 30d,,,2。:1~30d,31~90d。,,。2 COD3.2 ,、COD3。,20%~30%,80%,90%。,VFA,,。3 COD4 [4][5],,。,。CODBOD5,BOD5,BOD5/COD。-(CC-MS),。,。/,、、,。4/,,/,,,;,4560,,;/3518,/,/。5(a),,,。5(b),,,。6,,、;84 重庆建筑大学学报 第28卷4 GC-MS、5 6 。5 ,:,,,、。,,,。,BOD5/COD,,—。,。,,。,、。。,,。:[1] .〔J〕.,1998,19(6):56-59.[2] 〔M〕.:,1993.[3] .〔M〕.:,1998.[4] .〔M〕.:,2001.[5] .〔M〕.:,1999.[6] ,.〔J〕.,1995,17(3):118-125.[7] ,..〔J〕.,2005,27(5):87-90.85第2期 李东伟,等:二相厌氧处理有机废水过程特性及生物相研究
