改性粉煤灰SBR法处理洗涤剂废水的研究孙淑波

　　　201028　-SBR孙淑波(,　110045)　:利用改性粉煤灰絮凝、高效吸附作用和活性污泥法组合处理洗涤剂废水,通过实验考察改性粉煤灰和SBR方法的一系列参数对洗涤剂废水处理效果的影响情况,得到了整个工艺的优化实验条件。处理后废水COD、LAS去除率可达86.52%、86.10%。处理后水的各项指标均接近或优于工业回用标准,实现了“双废”的资源化。:粉煤灰;改性;SBR;洗涤剂废水;回用RESEARCHONTREATMENTOFDETERGENTWASTEWATERBYMODIFIEDFLYASH-SBRPROCESSSunShubo(FoundationDepartmentofShenyangPolytechnicCollege,Shenyang　110045,China)Abstract:Throughcomprehensiveuseofflyashmodifiedflocculation,efficientabsorptionandactivatedsludgetodealwithdetergentwastewater,andbyexperimentalstudyonmodifiedflyashandaseriesofparametersinSBRmethod'seffectondetergentwastewatertreatment,theoptimizedexperimentalconditionsforthewholeprocesshavebeengot.Theremovalrateofthetreatedwastewater'sCODandLAScouldreach86.52%and86.10%respectively.Indicatorsofthetreatedwaterareclosetoorbetterthantheindustrystandardandthusrealizingthereuseofthewastes.Keywords:flyash;modified;SBR;detergentwastewater;reuse　　,100Mt,,,,。、。,1996232.63t。,2000300t,2010420t[1]。,、;LAS,,,;COD,[2]。(SBR),,,,[3-9]。1　1.1　粉煤灰1。1　%SiO2Fe2O3Al2O3TiO2CaOMgOK2O55.698.5626.591.741.681.221.09Na2OMnOP2O5CO2SO3CuPb0.720.0680.240.500.3616035.01.2　改性粉煤灰的制备HCl∶H2SO4(2∶1),20mL10g,60min,。1.3　废水,,2。1DOI:10.13205/j.hjgc.2010.s1.010　　　2010282　ρ(COD)/(mg·L-1)ρ(LAS)/(mg·L-1)ρ(BOD5)/(mg·L-1)ρ(SS)/(mg·L-1)pH400～65080～160120～210300～9008.0～10.02　2.1　改性粉煤灰处理洗涤剂废水。、、pH、,:150mL,pH7,40min,50℃。,3。3,,,。　　　　　3　mg/L(pH)ρ(COD)ρ(LAS)ρ(BOD)ρ(SS)pH543.34137.30165.23615.39.095.1945.2358.5847.44.3/%82.4867.0664.5592.3-2.2　采用SBR法处理洗涤剂废水2.2.1　2,3,4,5,6,8h,2h、2h,5L,CODLAS,1。1　CODLAS　　1,,4h,,SBR。,,,,,,COD。,COD。2.2.2　4h,2h,5L,2,3,3.5,4,5h,COD、LAS,2。23.5h,COD、LAS,3.5hCOD、LAS,,SBR。,3.5h。2　COD、LAS2.2.3　4h,3.5h,5L,2.5,3,3.5,4,5h,COD、LAS。3。3　COD、LAS　　3:4hCODLAS,4h,,,。、,4h。2.2.4　pH4h,3.5h,4h,5L,pH4,5,6,7,7.5,8,8.5,9,10,pHCOD、LAS,4。　　pH(pH5),2　　　2010284　pHCOD、LASpH,,。4,pH5～8,,CO2、H2O、NH3,COD85%,LAS78%。pH8,、,,。COD。pH5～8COD、LAS。2.2.5　4h,3.5h,3.5h,2,3,4,5,6,7L,COD、LAS,5:5　COD、LAS　　5:,,,,,COD,。,20%～30%,SBR1.5L,6L。:4h,3.5h,pH6,6L,4h。,4。　　4　mg/L(pH)ρ(COD)ρ(LAS)ρ(BOD)ρ(SS)pH110.8952.2162.3141.036.014.957.7812.528.976.3/%86.5285.1079.7578.14-　　6,-SBR。,-SBR。3　1)150mL,pH7,40min,50℃,,COD、LAS82.48%、67.06%。SBR,:4h,3.5h,pH6,6L,4h。2),,COD、LAS86.52%、86.10%,,。[1]..[J].,1998,4:23-41.[2],,.LAS[J].,2000,1(1):65-71.[3],.[M].:,2001.[4],,.[J].,2003,29(118):24-26.[5].[M].:,2003,2.[6].[M].:,2001:7-196.[7]IrvineRL,BuschAW.Sequencingbatchbiologicalreactors-ano-verview[J].JWPCF,1979,51:235.[8]IrvineRL,KetchumJrLH,BreyfolgeR,etal.Municipalapplica-tionofsequencingbatchtreatmentatculver[J].JWPCF,1983,55:484.[9]IrvineRL,KetchumJrLH.Sequencingbatchreactorforbiologi-calwastewatertreatment[J].CRCCritRevEnvironControl,1988,18:255.　　110045　32　024-88252409E-mail　[e-mail]2009-06-113
