   201028EGSB反应器处理废纸造纸废水的实验研究*涂 勇1 郭方峥1 刘伟京1 解 林2 陆 娴2(1., 210036;2. 221008) :采用EGSB反应器处理废纸造纸废水,得出在进水COD负荷为10.03kg/(m3·d),上升流速为0.92m/h的情况下,COD去除率可达到72.41%。同时采用电感耦合等离子直读光谱仪对废水中的金属离子进行测定。并结合扫描电镜及颗粒污泥的成分,分析了废水中金属离子的转移规律。采用GC-MS对污水中的有机物进行测定,分析了有机污染物在EGSB反应器内降解及转化规律。:EGSB反应器;废纸造纸废水;电感耦合等离子直读光谱仪;GC-MSEXPERIMENTALRESEARCHONTHETREATMENTOFRECYCLEDPAPERPAPERMAKINGWASTEWATERBYEGSBREACTORTuYong1 GuoFangzheng1 LiuWeijing1 XieLin2 LuXian2(1.JiangsuProvincialAcademyofEnvironmentalScience,Nanjing 210036,China;2.SchoolofEnvironmentScienceandMappingofCUMT,Xuzhou 221008,China)Abstract:UsingEGSBreactorforthetreatmentofrecycledpaperpapermakingwastewaterwiththeinfluentloadabout10.03kg/(m3·d)andtheupflowvelocityabout0.92m/h,CODremovalratemayupto72.41%.ThemeasurementofmetalionsinthewastewaterwasalsodonebyAES/ICP.Integratedbyscanningelectronmicroscopeandcompositionofgranuleofsludge,thetransferruleofmetalsinthewastewaterhasbeenana-lyzed.Theorganicmatterinthewastewaterhasbeenmeasuredandtheirdegradationandtransformationruleshavebeenstudied.Keywords:EGSBreactor;recycledpaperpapermakingwastewater;AES/ICP;GC-MS*“”(2008ZX07101-003-005,2008ZX07313-005)。  ,,。。IC,IC,,IC,IC。EGSB。EGSB。1 1.1 试验用水水质,1:1 EGSBρ(COD)/(mg·L-1)pHVFA/mmol/%SS/(mg·L-1)/℃23007.0317.2952600301.2 试验装置及流程1。EGSB,φ0.2m×0.74m,22L。1.3 检测方法:COD:;:;TN:;MLSS、MLVSS;DO、:DO;pH:pH。PE5300DV,JY/T015-1996。GC-MS5975,GB/T6041-2002。102DOI:10.13205/j.hjgc.2010.s1.031   2010281 1.4 接种污泥。2 2.1 最佳进水负荷的确定EGSBCOD5.02,6.28,7.55,10.03,12.55kg/(m3·d)5。COD2。2EGSBCOD2,、,COD,,COD。COD5.02kg/(m3·d),COD2380mg/L,COD545mg/L,76.81%,COD17.06%;COD6.28kg/(m3·d),COD2380mg/L,COD596mg/L,74.96%,COD18.96%;COD7.55kg/(m3·d),COD2270mg/L,COD645mg/L,71.59%,COD20.62%;COD10.03kg/(m3·d),COD2402mg/L,COD756mg/L,68.53%,COD20.24%;COD12.55kg/(m3·d),COD2304mg/L,COD854mg/L,62.93%,COD24.71%。2,,,,。,,,,COD。,COD10.03kg/(m3·d)。2.2 最佳上升流速的确定EGSB10.03kg/(m3·d),,,:0.13,0.45,0.61,0.76,0.92m/h,,3。3 EGSBCOD3,0.13m/h,COD2402mg/L,COD756mg/L,68.53%;0.45m/h,COD2387mg/L,COD739mg/L,69.04%;0.61m/h,COD2435mg/L,COD714mg/L,70.68%;0.76m/h,COD2463mg/L,COD697mg/L,71.70%;0.92m/h,COD2345mg/L,COD647mg/L,72.41%。“”,,,,COD。2.3 氮磷的去除效果TNTP4。4EGSBTNTP,COD,,103   2010284 TNTP。2.4 金属离子的去除效果2。2 EGSBmg/LEGSBAl37.82.67Ba1.260.33Ca708419Cd00Co0.0250Cr0.140.008Cu0.350.036Fe29.90.93K23.818.8Mg44.928.7Mn1.670.65Na245270Ni0.110.038P6.214.49Pb00Sr1.250.89Zn1.040.23  EGSBpH,,。NaOHpH7.0。EGSB,,pH。pH,。、,。,。2.5 有机物的降解情况EGSBGC-MS,3。、5、6。5 EGSB6 EGSB3 EGSBGC-MSEGSB⑧⑩1322293610134344364621-32-12192025262728303334353739412627343741⑤⑦⑨141516172325⑨1517,、①③④1118313840①④43②④②⑥-4245  :1-1-2;2-1,3,5-;3-3-,2-;4-;5-2,3-;6-;7-1-;8-1,3;9-;10-;11-;12-2-;13-;14-2-,1-(2-)-;15-2-;16-;17-2--2-;18-3--6-(1-)-2--1-;19-;20--2-(2-);21--;22-2--4-;23-2-;24-(1--2-(2-PROPENYLOXY));25-;26-,2-,2,2-1-(2--1-);27-,2--3--2,2,4-;28-;29-2,6-;30-;31-;32-4--3-;33-2-;34-;35-;36-A;37-;38-;39-;40-;41-(2-);42-;43-;44-;45-;46-4,4'-(2,6-)104   201028  GC-MS41,6,1,1,14,9,,、8,2。EGSB21。6,5,3,,、3,2,2。3,EGSB、,、,3,、。。2.6 颗粒污泥的分析,。7。7 ,。4。4 %Mg2.504.03Al12.5918.29Si11.4115.92S11.2213.70Cl1.211.33K2.212.22Ca28.8228.17Ti7.436.08Fe6.104.28  ,,,、。,。3 1)EGSBCOD10.03kg/(m3·d),0.92m/h,COD72.41%,。EGSB。2)EGSB、,。3)EGSB、,、,、。4)EGSB,。[1].[J].,2000,l6(11):23-25.[2],,.GC/MS[J].,2005,21(1):54-57.[3]HanneVH,BirgitteKA.Intergratedremovalofnitrateandcarboninanupflowanaerobicsludgeblandker(UASB)reactor:operatingperformance[J].WaterResearch,1996,30:1451-1458.[4],.[M].:,2003.[5],,.[J].,2001,20(4):114-116.[6]NunezLA.Anaerobictreatmentofslaughterhousewastewaterinanexpandedgranularsludgebed(EGSB)reactor[J].WatSCiTeeh,1999,40(8):99-10.[7],,,.[J].,2006,22(24):35-37.  210036   E-mail tuyongnj@163.com2010-04-13105
